Sodium isostearyl lactylate contains a large amount of lactate structure, so it has a good Moisturizing effect. Sodium isostearyl lactyl lactylate has lipophilic characteristics. The ester group and lactyl group in its structure have better affinity for skin and hair. Water forms bound water that is difficult to volatilize, thereby slowing down the loss of moisture, and at the same time absorbing moisture in the air, so as to achieve the purpose of high-efficiency moisturizing.

Lubricating and regulating effect: Sodium Isostearoyl Lactylate has good affinity to skin and hair, can be easily adsorbed on the surface of skin and hair, and has strong lubricating feeling and film-forming property. Form a thin film on the surface of the hair, which plays the role of moisturizing, lubricating, hair care, eliminating static electricity, conditioning and so on.
