Snail Soap by Auntie Clara's

Double, Double Toil and Trouble: Snail Soap

posted in: Auntie Clara's Blog, Blog Post | 37

Here, close to the southernmost tip of Africa, our summers are warm and dry. The rain falls in winter when low-pressure fronts sweep in from the south.

This is the heartland of South African wine country and the local vineyards spend their dormant winter months enjoying the cool winter rain. And where vines grow, snails tend to thrive.

During the winter months our local vineyard snails have a feast on fallen vine leaves and various weeds growing in the vineyard. That’s all fine and well, but when the new leaves grow and the inflorescence forms the farmer doesn’t want snails around.

I like escargot a lot. A few years ago looking at the abundance of snails in the local winter vineyard got me thinking. What if I could harvest some of those snails and turn them into escargot?

Well, with a little googling I could establish that our local snails were indeed the edible kind: Cornu aspersum, previously known as Helix aspersa.

With a little more googling I learnt that snails harvested in ’the wild’ are best kept on a controlled diet for a few weeks, then given water only for a couple of days and then they’re ready for the pot.

This was many years ago and since then I usually collect myself a yearly ’snail farm’ in the local vineyard when winter is coming to an end. It always makes me feel like quoting  – in the Danish accent put on by Meryl Streep – that timeless first line in Karen Blixen’s novel Out Of Africa:

“I once had a farm in Africa..”

Collecting the snails is easy because there are lots and it usually takes me about 45 min to gather my two to three kg. Three kg is the most I’ll take; that amount fits in my clam-shell snail cage made of two plasic crates.

About a month ago I was once again crouching between the vines gathering snails for this year’s snail adventure. And once again I was reminded of the sexy snail picking scene in the novel Captain Corelli’s Mandolin by Louis de Bernières. It’s a great book, I can warmly recommend it – and not just for the snail picking. Of course there’s also the film version where Penelope Cruz teams up with Nicholas Cage in the steamiest quest for gastropods in film history…

So, farming snails for escargot I’m well familiar with, but until recently I would never have added snail in any form to soap. In the past I’ve joked about snail slime being the weirdest soap ingredient conceivable, and I would never have considered using it. Because seriously, who would want to use soap made with snail slime?


Seriously, who would want to use soap made with snail slime?

That’s what I thought until recently when I happened to come across a few articles about snail mucin (a dignified euphemism for snail mucus or slime) – or snail secretion filtrate as it’s called by its INCI name.

Apparently snail slime is a veritable cocktail of wholesomeness. Snail slime is a hot trend in the beauty industry and snail slime cosmetics have a significant following in Korea where general beauty-product consciousness is high. In ancient times the Greeks along with various other peoples used snail slime to heal wounds and burns. But legend has it that credit for the modern-day re-discovery of the benefits of snail slime goes to Chile. Workers on farms producing snails for restaurants in Europe noticed that constant contact with snail slime did wonders for their hands. The skin was rejuvenated and cuts and scars healed exceptionally fast. Somebody decided to put the slime in a jar and sell it and so snail slime cosmetics became a reality.

So what makes snail slime so special then? Well, snails secrete slime for their own protection. Snails eat anything, negotiate all kinds of terrain and frequently find themselves in less than clean environments. The mucous membrane covering their bodies is soft and vulnerable to cuts, abrasions, sunlight and bacteria. The slime is a perfect, natural protection and healing substance. It offers UV protection, is antimicrobial and contains e.g. allantoin which regenerates skin tissue and soothes irritated skin, collagen and elastin which give the skin strength and elasticity, glycolic acid which works as an exfoliator and may help lighten dark spots, and hyaluronic acid which is a regenerating and moisturizing agent softening and lubricating the skin.

Snail slime serums and creams are said to effectively moisturize and lubricate skin, reduce inflammation, reduce acne scars, lighten the skin, and offer some UV-protection.

All that sounded very impressive and suddenly snail slime didn’t seem all that gross anymore. Seeing that I had 3kg of snails fixing to become dinner I decided I might as well not waste anything and give snail soap a chance after all.

"I can see ya"
“I can see ya”

Now, snail slime creams as well as snail slime itself may come with all those beneficial components mentioned above, but snail soap is a bit of a different animal. Firstly, saponification involves an initial pH of 14 which is a tough environment for many substances. Would any of all the good stuff survive the lye attack?

Well, it turns out that hyaluronic acid, glycolic acid as well as collagen and elastin are all used in cosmetics in hydrolyzed form. Saponification is a form of hydrolysis so in all likelihood they can take the lye attack. This process of hydrolysis also means that snail slime in fully saponified coldprocess soap has been broken down and isn’t slime anymore. However, since soap is a rinse-off product typically spending a very brief moment on the skin, it’s by no means guaranteed that any of these goodies will have time enough to impart any lasting effect on the skin.

But, soap is also to a great extent about instant gratification as in the performance of the bar while in use. Hydrolyzed proteins typically add creaminess and cushioned slip (’silky feel’) to soap lather. So, if nothing else, the protein content in snail slime can be expected to influence what the snail soap feels like while you’re using it.


There’s slime and then there’s slime..

I had the snails in a cage on a diet of the coarsely ground corn flour known as ’mielie meal’ in South Africa. A controlled environment and diet helps ensure that the snails are as clean as possible when it’s time to use them. But how would I be able to extract the slime?

A snail secretes two types of slime. One underfoot to ’pave it’s way’ as it were. The other type of slime is secreted when the animal is stressed and this is the slime that is so regenerating, rejuvenating and moisturizing for the skin. So, in order to extract the right kind of slime you stress the snail. This can be done without killing the animal, but I wouldn’t call it ’cruelty free’. On the other hand it’s probably no more cruel than killing snails with salt, snail bait – or ducks. I’ve seen pictures of snail facials where snails peacefully crawl over somebody’s face. While that may feel cool and give rise to fabulous photo opportunities, it’s probably not going to give you the most potent slime.


The process

When the snails had been on their corn flour diet for about three weeks and on water only for a couple of days, it was time for the pot.

First, they got hosed down one last time in the cage.

This, by the way, is my first blog collaboration with my daughter Alice, who kindly helped document the slime extraction process with photos.

Then the snails got rinsed carefully one by one. Given how dirty the environment can be where you find snails, the animals themselves are usually remarkably clean. However, dirt may stick to the shell and you want to remove that before cooking them or extracting slime.

After that it was time to collect some of that precious slime. ’Precious’ is not just a cute expression here; according to one article some companies pay up to 1000 Euro a litre for snail secretion filtrate. Seems like we have some green gold right there.

To extract the slime I ’massaged’ each snail. That’s a time-consuming job and it took me a good hour to collect about 130g of snail slime. That’s about 10% of the oil weight of my intended soap batch. I didn’t count exactly how many snails were involved, but it was roughly a third of my three kilos of snails..

When I was 15 you could buy prank slime in little green containers in a shop close to my school in Helsinki. I still remember the colour and moist feel of that prank slime and knowing what I know now about snail slime, I must give the prank slime manufacturers some credit: they got it exactly right. Thick, moist and soft but very stringy. Even the lime green colour was spot on.

Making snail soap

After this I made the lye solution for the soap. There was no way I would have been able to evenly incorporate the thick, heavy slime into my oils so the slime would have to go in the lye solution. Snail slime is more than 90% water, but I didn’t know how easy or difficult it would be to dissolve the thick mucus with lye so I decided to add strong green tea infusion at equal weight to lye.

The stickblender had some hard work to do mixing the green tea with the slime, but eventually I couldn’t see any big lumps anymore and so I added the lye. It all mixed nicely and everything dissolved easily and perfectly without ’floaties’ of any kind. As I poured the solution through a strainer into my oils the only thing left in the strainer were a couple of little pieces of shell.

I chose to make this experimental formula coconut-free. I expect it’s going to be used mainly by myself so I wanted to make a soap that would be comfortable to use on my own old-bird face. Keeping olive oil at about 25% (I resisted the temptation to make my slime soap from 100% olive oil 🙂 ) I added lots of avocado oil and shea butter – and a generous helping of castor oil to sustain lather. I also added a little regular sunflower oil to bring up the linoleic acid content to 15%. Linoleic acid has a relatively short shelf life, but I’ve learnt that my skin loves it so I like to make sure that I have some in soap that I make for myself.

To that I added an essential oil blend of geranium, chamomile, lavender, petitgrain, neroli and a few drops of patchouli. I love to hate patchouli. I’m very sensitive to the smell and can’t stand it by itself but I love the depth it gives in a blend in very low concentration.

I made coldprocess soap so no actual Shakespearean bubbling cauldrons for this snail soap. The soaping was uneventful and once poured the bars each got a little shell embossing with my inverted stamp tool.

My little bowl-scraping test piece was oven processed along with the other bars and performed very nicely as I tried it out the following morning. No slime, but with a rich, creamy and nicely cushioned lather – and a beautiful scent.

I’ve been using my snail soap for a few days now and the coconut-free formula feels great on my skin. The bar is nice and hard and will continue to harden as it cures. For anybody keen to know what snail soap can be like, I’ve released a few bars in Auntie Clara’s Soap Shop.

Gastropods for gourmets

“And what happened to the snails?”, you might ask. Well, first they were quickly killed in boiling water. After that I picked the meat out of each shell with a lobster fork. That’s also a laborious task – snails are slow food on so many levels!

Once all the meat – a little less than a kilo and a half – was out of the shells I slowly simmered it in a broth of a bottle of sauvignon blanc from another neighbouring vineyard, 500ml water, a couple of onions, a few cloves of garlic, a handful of fresh thyme from the garden, a couple of fresh bay leaves (Laurus nobilis) also from the garden, salt, black pepper – and one clove for good luck.

After about an hour the snails were ready. Some were packed away, destined for the freezer to be served at later dates. Some were transferred to snail dishes, sprinkled with a generous amount of ground pistachios and drizzled with garlic butter. A quick visit under the grill, a sprinkling of finely chopped, fresh flat-leaf parsley and they were ready to be enjoyed with some hot, crisp ciabatta and a nicely wooded chardonnay. Delish!

Snail Broth Wine

I’m very pleased with this year’s snail adventure. Enjoying ’wild-crafted’ escargot and using soap made with snail slime might not be everybody’s cup of tea. It probably requires a bit of an adventurous mindset. That’s fine, I’ve got plenty of that so it works well for me. And I’ll be the first to admit that I do this kind of thing “because I can”. Maybe one day when I grow up I’ll be more rationally motivated, but for now the romantic notion of making use of something that is literally available at my doorstep seems richly satisfying. And if I can get a delicious meal and some really nice soap in the process – so much the better 🙂

With that I wish you all a Happy Halloween!

    WOW… definitely snail adventure as you put it. I wouldn’t have believed it if I didn’t just see & read about it. So much care and attention went into this project. I love the shell embossing and have never heard of an inverted stamp tool – perfect finishing tough on this truly unique soap. I laughed when you said “snails are slow food on so many levels” – you aren’t kidding! Amazing job you did with this project & this post – I’ll definitely be sharing it with my students. I would absolutely be buying this if the shipping to US wasn’t so high. Your soaps are gorgeous and a work of art!

    • Clara

      Thank you Lori! You can read more about inverted stamp tools and inverted stamp technique in this blogpost International shipping is always expensive, but if you order six bars the total including shipping will be less than $10 per bar at today’s (3 Nov 2016) exchange rate. That’s not so bad, is it?

      • Lori Nova Endres

        Thanks Clara for that link, I will check it out. I was really surprised at the reasonable price of your amazing soaps (pre-international shipping). Lucky local folks! Perhaps you need a distributor in the states??? Just a thought. 😉

        • Clara

          Even with international shipping my products shipped from here to your door will be much less expensive to you than many corresponding products on the US market. Makes you think, doesn’t it? 😉

  2. Beth Byrne

    Snails make my skin crawl, so I read this with a kind of morbid fascination. You won’t find me harvesting snails anytime soon, or eating escargot, but you are intrepid!

    • Clara

      Most things cooked with plenty of butter and garlic are delicious. Snails are no exception. You should try.. 🙂

  3. Eileen Wosnack

    Hello Clara,
    You never cease to amaze me! Your writing is entertaining and the subject matter of this blog, though perhaps controversial, makes for quite a wonderful read. Along with the small excerpts from books and movies, to the pairing of the wine for the gastronomic delight, the adventure was exquisite! Thank you for sharing and for being yourself!

  4. DrJohn

    What a great story. I may have to try this sometime, but since the drought the snails have all but disappeared in my southern California garden.

    • Clara

      I think most gardeners would be pleased if anything caused the snails to disappear from the garden.. 🙂

  5. Valerie

    Oh my gosh., I have to admit my stomach did some weird movings, along with my throat, as I read this, I too can be adventurous, but just not sure if I can eat snails or use their slime in my soaps! Lol! I’m not actually closed to the idea, but I feel relatively safe that it won’t be on my ‘to do’ list anytime soon. Living in the US, my back yard (or any place close by) is not conducive to raising snails, ha ha! So please tell me……….what do snails taste like? I do love your post! You’re an inspiration to the Soapmaking community!

    • Clara

      Well-cooked snails have a pleasant texture (not tough) and a mild but pleasant taste slightly reminiscent of Portobello mushrooms. Of course they’re mostly served with plenty of butter and garlic and so they tend to taste a lot like butter and garlic – which is also nice.

  6. Janet Stewart

    Love your daughters pics and your blog. Very interesting. Im sure you are the first person ever to make snail soap!

  7. Annik

    Ohhh!!! The Halloween’soap by Clara Witch! 🙂
    Thank you so much for sharing!

  8. Amanda

    Ahhhhhhh! I have to say, this was a bit hard to read and see! Snails just eek me out. But I am completely applauding you for adventure, wonder and boldness! 🙂 I can’t say I’d make it myself, but I’d try the soap! <3 <3 I think this is the most unique soap ingredient I have ever seen.

  9. Mally

    Beautiful pictures. Loved the article. One question doesn’t the snail release harmful toxins. I wouldn’t suggest eating the ones you massaged the protective muscus from;)

    • Clara

      Hi Mally. Common garden snails like the ones I used are not toxic – unless they’ve recently eaten something toxic. You keep the snails on a controlled diet for a feaw weeks to make sure they are perfect for eating.

  10. carolyn newton

    Clara, You come up with the most spectacular things to add to soap! Who would ever think to put snail slime in soap? Auntie Clara, that’s who lol. Loved reading this post, you are such an inspiring soap maker. I would never eat snails but apparently they are very tasty and my husband likes them. Look forward to seeing what you next put into your soaps!

    • Clara

      Lol Carolyn! It’s true that I keep an open mind, but I also like to think that anything ‘odd’ that goes in does so for some good reason and adds something valuable to the product. In the case of the snail secretion filtarte it seems to add a soft, cushioned feel to the soap lather which I quite like. It’s rewarding when something that starts purely as an experiment actually turns out to be nice.

  11. abdelilah

    hello, my traning period’s topic its was about slime of snils, and i have a question; why did you use a strong green tea ? did it has a impact about the pruduct ? please answer me

    • Clara

      Hello Abdelilah. The caffeine in green tea has soothing and antioxidant properties. Does it significantly change the long term effect of a rinse-off product in use? Hard to make any conclusive statements about that without extensive clinical testing.

  12. sandar

    hello, nice info but i would like to ask if we could just add the slime to a melt and pour base and then use like that

    • Clara

      Yes, if that is what your heart desires 🙂 I can’t make any predictions about the actual snail gel content in the soap you came across – or about the other ingredients including superfat. Only the manufacturer can give you the facts you need to make an informed decision.
