What Is Sodium Lauroyl Sarcosinate?
Sodium lauroyl sarcosinate is a synthetic surfactant and foaming agent commonly found in a wide range of personal care and cosmetic products. This compound is derived from sarcosine, an amino acid that occurs naturally in the human body, and lauric acid, a fatty acid typically obtained from coconut oil.
Chemical composition
The chemical formula of sodium lauroyl sarcosinate is C15H28NNaO3, and it is classified as an anionic surfactant. This means that it possesses both hydrophilic (water-attracting) and lipophilic (oil-attracting) properties, making it an effective emulsifier and detergent.
Applications
Sodium lauroyl sarcosinate finds its way into a wide array of personal care and cosmetic products due to its versatile properties:
- **1. Shampoos and Conditioners:** It helps create a rich, creamy lather and aids in the gentle cleansing of the hair and scalp.
- **2. Facial Cleansers:** Sodium lauroyl sarcosinate is prized for its ability to remove dirt, makeup, and excess oil without over-drying the skin.
- **3. Toothpaste:** It contributes to the foaming action of toothpaste, assisting in the even distribution of the product while cleaning teeth and gums.
- **4. Shaving Creams and Foams:** Its emulsifying properties make it an excellent choice for creating smooth, lubricating lathers for a comfortable shave.
- **5. Body Washes and Shower Gels:** Sodium lauroyl sarcosinate enhances the cleansing experience by generating a luxurious foam.
