In fact, heliciculture or land snail breeding has for centuries been producing escargots and escargot-pearls (snail eggs, a type of caviar) popularly eaten in France. But a high demand for snail slime used as an ingredient in cosmetics has resulted in a 325% rise in production of snails in Italy alone where 44,000 tons of snails are bred annually.
In the 1980s some Chileans who sold snails to the French discovered the so-called benefits of snail slime, but Korea was responsible for introducing beauty products containing it. Snails are specially bred for the purpose in Korean farms. Fast-rising sales of products made from snail slime indicate women do not mind applying this obnoxious animal substance on their faces thinking it will improve their skin. Yuck!
The School of Mechanical Engineering, Sungkyunkwan University, Suwon, South Korea, and the Department of Physics & Astronomy College of Science, King Saud University, Saudi Arabia, participated in a study carried out on a species of terrestrial snails called Achatina fulica, that is an agricultural pest in Kerala and found that snail mucus is a mixture of glycoproteins, hyaluronic acid and glycolic acid, all of which have long-documented benefits for the skin.
Snail slime, an unpleasant, slippery and thick semi-solid substance processed and packaged as creams, gels and serums by some foreign cosmetic companies is very much in demand. Snail mucin as it is called, claims to help recovery and regeneration of skin. Then there’s snail-based eye cream, toner and moisturiser, even a premium snail gel face mask.
The production of slime or mucus trails in snails facilitates locomotion and trail-following is important for mate-searching. If snails move over previously laid trails, they can save their own energy.
The traditional way to force snails to secrete their slime is by immersing them in water containing salt, vinegar and chemicals. The modern method is to immerse them in a special steam bath called Muller One which extracts the slime with water that contains ozone which kills bacteria.
Normal slime is viscous and sticky, but if the snails are forced to secrete a discharge it is clear and foamy making it ineffective by self-certified manufacturing standards! Companies that market snail slime products are therefore said to be conning thousands of ladies. Meanwhile, dermatologists do not agree that creams made from snail slime (however derived) iron out wrinkles.
However in September 2021 the Nature Journal published that a group of researchers from the Shiv Chhatrapati College, Junnar, in collaboration with the Department of Technology at the Savitribai Phule Pune University and the Centre for Materials for Electronics Technology had found that the sticky mucus secreted by snails was a novel biomaterial for synthesis of silver nanoparticles that were found to be effective for fungal infection, anti-microbial activity in human body and to avoid injury scars. They saw nothing wrong at all in exploiting snails to obtain their secretions and expressed the possibility of a topical cream/gel for acne treatment as well as for rapid wound healing; and would be extended to the formulation of an anti-cancer cream.
Lime or Choona
The shells of molluscs and particularly snails collected from the sea by local persons off the coasts of particularly Kerala and Odissa are used for the production of lime or choona utilised in umpteen applications including food in India.
