Sodium lauroyl sarcosinate is derived from sarcosine, a natural amino acid found in the human body and just about every type of biological material from animals to plants. 
Sodium lauroyl sarcosinate is made from coconut oil.
Sodium lauroyl sarcosinate is a cleanser and foam booster that helps with the effectiveness and feel of our toothpaste.
Sodium lauroyl sarcosinate (INCI), also known as sarkosyl, is an anionic surfactant derived from sarcosine used as a foaming and cleansing agent in shampoo, shaving foam, toothpaste, and foam wash products.
Sodium lauroyl sarcosinate is amphiphilic due to the hydrophobic 12-carbon chain (lauroyl) and the hydrophilic carboxylate. 
Since the Sodium lauroyl sarcosinate is in an amide linkage, Sodium lauroyl sarcosinate is not pH active and is neutrally charged in all aqueous solutions regardless of pH. 
The carboxylate has a pKa of about 3.6 and is therefore negatively charged in solutions of pH greater than about 5.5.
PH-sensitive vesicles can be prepared using this surfactant with another cationic or water-insoluble amphiphiles such as 1-decanol.
Addition of an mixture of equal parts of sodium lauroyl sarcosinate and the non-ionic surfactant sorbitan monolaurate (S20) to water led to the formation of micelle-like aggregates, even though neither surfactant formed micelles when present alone. 
Such aggregates can help carry other small molecules, such as drugs, through the skin.

Sodium lauroyl sarcosinate was sold as a special ingredient called "Gardol" in Colgate "Dental Cream", as toothpaste was then called, during the 1950s through the mid-1960s in the US and the mid-1970s in France. 
Sodium lauroyl sarcosinate, like sodium lauryl sulfate, is a cleansing and foaming agent, but that is where the similarities end. 
Derived from sarcosine, an amino acid that occurs naturally in the body, sodium lauroyl sarcosinate is frequently heralded for being a thorough cleanser but also for being gentle. 
Sodium lauroyl sarcosinate works by attracting excess oil and dirt, then carefully removing the grime from the hair by emulsifying it so it rinses easily away with water. 
In addition to cleaning the hair, regular use of a shampoo with sodium lauroyl sarcosinate has also been shown to improve the appearance of the hair (especially locks that are damaged) by boosting shine and body.

Sodium lauryl sarcosinate is the salt of lauryl sarcosine.
Sodium lauroyl sarcosinate is a powder or liquid and is derived from coconut.
Coconuts grow on the cocos nucifera, or coconut palm tree. 
Coconut palms grow around the world in lowland tropical and subtropical areas where annual precipitation is low. 
Widely cultivated, healthy coconut palms produce 50 nuts per year, and the tree can be used to produce everything from food and drink to fibers, building materials, and natural ingredients.
The accolades don’t end there though. 
Listed in the Handbook of Green Chemicals, sodium lauroyl sarcosinate gets the thumbs up from most green and clean beauty advocates—which is one of the reasons Prose has chosen to make it one of its primary cleansing agents in our shampoos. The other reason Prose uses it? It works so well, gently cleansing the hair without ever over-stripping. And as with most Prose ingredients, we aim to get our sodium lauroyl sarcosinate from the highest quality, most-natural source we can find. Thus, our sodium lauroyl sarcosinate currently comes from coconuts.
