The gum raw material is a water-soluble polymer compound, which can swell into a colloid in water. It has a variety of functions when used in cosmetics.
The gum raw material can make the solid powder stick and shape. It can be used as an emulsifier for emulsions or suspensions.
The water-soluble polymer compounds used in cosmetics are mainly divided into two categories: natural and synthetic. Natural water-soluble polymer compounds include starch, vegetable gum, animal gelatin, etc.
Synthetic water-soluble polymer compounds include: CMC, polyvinyl alcohol, polyvinylpyrrolidone, etc. They has the advantages of stable properties, low skin irritation and low price. They are the main source of gum raw materials.
Synthetic water-soluble polymer compounds is also divided into semi-synthetic and synthetic water-soluble polymer compounds.
Methyl cellulose, ethyl cellulose, sodium carboxymethyl cellulose, hydroxyethyl cellulose, guar gum and its derivatives are widely used semi-synthetic water-soluble polymer compounds.
Synthetic water-soluble polymer compounds include: polyvinyl alcohol, polyvinylpyrrole.
In addention, xanthan gum, acacia gum, carrageenan, agar gum, gelatin, magnesium aluminum silicate, etc, are also widely used in cosmetics.
