Emulsifying

Ingredients with the emulsifying function help to combine components in one formula that usually do not mix well, such as water and oils. In fact, they contribute to the formation and stabilization of an emulsion, a system where the smallest droplets of one liquid are distributed in another. Due to this, the cream, lotion or milk does not exfoliate, retains a uniform texture, is easier to apply and spread over the skin or hair. In official European materials, such substances are described as agents that support the mixing of immiscible phases, and in chemical reference books, an emulsion is defined as a mixture of liquids where one is present as small droplets in the other.

For the consumer, this means not only a pleasant consistency of the product, but also more comfortable use. In skin care, such components make creams and serums more silky, help to evenly distribute lipids, moisturizers and protective substances over the skin surface. In hair products, they improve the texture of conditioners and masks, help the oil and water phases work as a whole, making the product easier to apply along the length and not disintegrate into separate layers in the bottle. Emulsifying substances often have surface activity at the same time, that is, they are located at the boundary of oil and water and keep the system stable.

Typical examples of such ingredients are Glyceryl Stearate and Polysorbate 60. They can be found in creams, cleansers, balms, and sunscreen formulas, where stability, soft distribution, and uniform texture are especially important. By themselves, they are not the main "asset" of care, but they largely determine how convenient, stable and pleasant the product will be to use.
