Ingredient
METHYL GLUCETH-20
Substance information
The methyl group is one of the simplest arrangements of atoms in organic chemistry which can be found as a moiety of numerous organic molecules. The name „methyl“ is derived from methane, the member of the alkane hydrocarbon group with the lowest molecular weight. The methane molecule contains four hydrogen atoms each one bound to a central carbon atom. The methyl group is not an independent chemical entity and contains only three hydrogen atoms, the fourth binding site is generally used for binding to a larger, mainly organic molecule. Like all alkanes, methyl groups exhibit a particularly low chemical reactivity.

Background information on use in cosmetics
Polyethylene glycols (INCI: PEG-...) are poly condensation products of ethylene glycol, or polymerisation products of ethylene oxide. The number added to the name refers to the mean number of ethylene oxide units in the substance. The consistency of the PEG derivatives is increasingly solid with a growing degree of polymerisation. PEGs with a mean molar mass of up to 600 g/mol are liquid, up to 1,000 g/mol wax-like and from 4,000 g/mol solid wax-like substances. By mixing solid and liquid components, products of a creamy consistency are obtained which are used as water-free and water rinse-off bases. With growing molar mass water solubility and hygroscopicity (ability to absorb moisture) of the polyethylene glycols decrease.
