Main Applications and Effects

Main applications

  • Hair care products
  • Body care products

Sodium isostearoyl lactate is a compound made from lactic acid and fatty acids (isostearic acid). These compounds are frequently used as materials in cosmetics. Lactic acid and its salts are main components of natural moisturizing factors, which have emollient and water-retention effects on skin. Because of this high level of affinity, using just a small amount has a lasting effect on skin and hair.

With hair/skin protective properties and curl-retention properties that are long-lasting even when used with other products, it is often used in shampoos and soaps.

When added to hair products, it produces an effect similar to that of silicone, which detangles hair and eases brushing. When added to body products, it helps such products remain in the skin, prevents stretched feeling after washing, and helps improve dried skin.
