Science
Mechanism of Action
This amphiphilic N-acylamino acid acts as an anionic surfactant, reducing surface tension to allow water to effectively mix with lipids and impurities for rinsing. Its unique sarcosine head group interacts with polar surfaces, contributing to refined product texture and an enhanced skin feel. Furthermore, Oleoyl Sarcosine demonstrates antimicrobial and virucidal properties and has been noted to potentially enhance the transdermal delivery of co-formulated ingredients.

Stability
Oleoyl Sarcosine exhibits robust chemical stability across a wide pH range, including high alkaline conditions, due to its carboxamide structure. While primarily soluble in oil and various organic solvents, it can be effectively solubilized in water under alkaline pH conditions.

- Strong oxidizing agents
- Ingredients known to lead to the formation of N-nitroso compounds
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concludes that Oleoyl Sarcosine is safe for use in rinse-off products. For leave-on applications, it is considered safe at concentrations up to 5%, provided the final product is formulated to be non-irritating. A critical safety consideration involves avoiding co-formulation with ingredients that could lead to the formation of N-nitroso compounds, as sarcosine can potentially nitrosate into N-nitrososarcosine, a compound of toxicological concern. While related N-Acyl Sarcosines are FDA-approved for specific food contact uses, and Oleoyl Sarcosine is listed in the FDA's inventory of food contact substances, data concerning safety for inhalation exposure is currently insufficient.
