What is the emulsifier of cosmetics?

Emulsifiers have the characteristics of surfactant, hydrophilic group and oil group in molecules. Therefore, in the oil-water system, after adding emulsifier, water and oil can be mixed with each other to prevent oil-water separation and stabilize product performance. Emulsifiers have the following hazards that can not be ignored: destroying skin tissue structure, reducing immunity, making skin sensitive and highly carcinogenic.

Emulsifier refers to the surfactant that can stabilize the emulsion. Therefore, after adding emulsifier into the oil-water system, water and oil can be mixed with each other to form a completely dispersed emulsion. Emulsifier can not only improve the stability of emulsion, but also determine the type of emulsion.

Emulsifiers can be divided into natural emulsifiers and synthetic emulsifiers according to their sources. According to the type of action, it can be divided into surfactant, tackifier and solid adsorbent; According to its lipophilicity and hydrophilicity, it can be divided into lipophilicity and hydrophilicity.

Why should emulsifier be added to skin care products?

Because in the skin care products we use, especially in the cream and water emulsion products we commonly use, the ingredients of these things are very complicated. Among them, you will see that the first item in the ingredient list says water, and the proportion of water in many skin care products often exceeds 80%. In addition, there are pigments, various preservatives, oils, perfumes and so on. These ingredients are incompatible with each other, and only by adding emulsifier can these ingredients be stable and lasting.

Emulsifier can dissolve oil, including sebum, destroy sebum membrane, cause skin barrier damage, cause skin sensitivity and other skin problems. Emulsifiers are the same as amino acids and soap bases in our daily cleansing products. Emulsifier belongs to surfactant component.

Just as everything has two sides, so does emulsifier. Not all emulsifiers will make the skin abnormal. After all, many natural animals and plants can also extract emulsifiers, and many natural emulsifiers can also protect and repair the skin.
