Sodium myristoyl sarcosinate

Harm score: 2 (Derivatives of natural substances)

Sodium myristoyl sarcosinate, also known as Pearl, Pearl powder or Hydrolyzed pearl powder, is an active ingredient used in many cosmetic and skin care products. This substance is derived from myristic acid, which is commonly found in animal fats and oils. Sodium myristoyl sarcosinate is a surfactant, which means that it reduces the surface tension of aqueous solutions and increases the dispersion properties, thereby improving the distribution of the other ingredients in the formulation. This effect makes it useful in many skin cleansing and skin care products.

The products to which sodium myristoyl sarcosinate is most commonly added include shampoos, conditioners, shower gels, facial cleansing gels and even toothpastes. Due to its properties, this ingredient can help remove dirt and create foam in aqueous beauty products. It can also be found in some types of makeup, as it can improve the consistency and help in spreading evenly on the skin. It is suitable for all skin types and is generally considered mild and non-irritating, making it an ideal ingredient for products designed for sensitive skin. On the other hand, it is important to note that as with all cosmetic ingredients, sodium myristoyl sarcosinate can cause allergic reactions in people with hypersensitivity to this ingredient.
