Emulsifiers

Emulsifiers

Emulsifiers are chemicals that can mix two immiscible substances together. In cosmetics, the role of emulsifiers is to make water and oil mix evenly together to form a stable emulsion. This can increase the texture and touch of the product on the one hand, and improve the stability and moisturizing properties of the product on the other hand, making it easier to be absorbed by the skin. Emulsifiers play a very important role in cosmetics and can effectively improve the use experience and effect of the product.

Emulsifiers Mechanisms

Emulsifiers play the role of mixing water and oil phases in cosmetics. Since water and oil are two incompatible substances, it is difficult for them to mix together and remain stable without the help of emulsifiers. The molecular structure of emulsifiers is both hydrophilic and lipophilic, which allows it to form a film between the water phase and the oil phase to wrap them together. When an emulsifier is added to cosmetics, it reduces the surface tension between water and oil, making them easier to mix and form a stable milky liquid. This combines water-soluble and oil-soluble ingredients, making cosmetics easier to apply and absorb, and providing better efficacy.
