Sodium Lauroyl Sarcosinate
Also Known As: Sodium N-(dodecanoyl)-N-methylglycinate, Sarcosyl
What Is It? Sodium Lauroyl Sarcosinate is an anionic surfactant derived from sarcosine, a natural amino acid found in the human body. It is commonly used as a foaming and cleansing agent in various personal care products.
What Makes It Different? Unlike harsher surfactants like Sodium Lauryl Sulfate, Sodium Lauroyl Sarcosinate is known for its mildness. It effectively cleanses by attracting and emulsifying dirt and oil, allowing them to be easily rinsed away without stripping the skin or hair of their natural oils. This makes it suitable for sensitive skin and hair types.
Where Does It Come From? Sodium Lauroyl Sarcosinate is derived from sarcosine, which can be obtained from natural sources such as coconut oil or synthetically produced. The lauroyl component is typically sourced from coconut or palm kernel oil.
Where Is It Used? This ingredient is widely used in:
- Shampoos
- Toothpastes
- Shaving foams
- Facial cleansers
- Body washes
Is It Sustainable? Sodium Lauroyl Sarcosinate is considered to be a more sustainable option compared to some other surfactants. It is biodegradable and less likely to cause environmental harm. Additionally, when sourced from natural ingredients like coconut oil, it supports the use of renewable resources.
Sustainable Issues Related to Its Production: While Sodium Lauroyl Sarcosinate itself is biodegradable, the sustainability of its production depends on the sourcing of its raw materials. If derived from palm oil, there are concerns related to deforestation and habitat destruction. Therefore, it is crucial to ensure that the raw materials are sourced sustainably, preferably from certified suppliers that adhere to environmentally friendly practices.
Overall, Sodium Lauroyl Sarcosinate is a gentle, effective, and relatively sustainable surfactant, making it a popular choice in the formulation of personal care products.
