AVOCADO OIL GLYCERETH-8 ESTERS

Substance information

Ingredient on the basis of avocado oil (persea gratissima oil). "Glycereth-" refers to a PEG-(polyethylene glycol-) ether of glycerin. The number behind "glycereth-" refers to the average number of molecular units -CH2-CH2-O-. "Ester" or "esters" refers to an esterification product (condensation product of alcohol and acid) or a trans-esterification product obtained through direct reaction of fats (mostly triglycerides) with alcohols.

Background information on use in cosmetics

Avocado oil (INCI: persea gratissima oil) is a rich oil which is obtained from the ripe fruit of the avocado tree. The avocado tree belongs to the family of lauraceae and originates from Central America. Already the Aztecs appreciated the oil and other plant parts of the tree and the oil is still used in various forms in the cosmetic and pharmaceutical industries. In cosmetic products it is particularly appreciated for its caring properties in skin and haircare. Avocado oil contains a lot of Vitamin E and A and is rich in unsaturated fatty acids such as oleic and linoleic acid. The oil is well received by the skin and makes it smooth and supple. It is particularly suited in the case of brittle and flaky skin, since it protects the skin from desiccation and supports cell regeneration. In haircare, the high-quality oil is often used. Dry hair benefits, for instance, from the caring properties of the avocado oil smoothening the hair structure and providing the hair with more gloss. Surfactants are so-called detergent substances and have a major significance in cosmetics for the cleansing of the skin and hair. Surfactants are substances which, based on their molecular structure, are able to reduce the surface tension of a liquid. In this way it is possible that two actually not mixable substances, such as oil and water, can be finely mixed. Because of their properties, surfactants have manifold uses in cosmetics: they can cleanse, produce foam and act as emulsifiers and mix substances with one another. In shampoos, shower gels and soaps, surfactants are, for instance, used to wash fat and soil particles with water off from the body. Surfactants are also used in toothpaste. Here they promote during tooth cleaning the rapid and full dissolution and distribution of the paste in the mouth. The surfactants used in cosmetic products are primarily produced synthetically on the basis of vegetable raw materials. Surfactants are often used in combination to equally meet all desired requirements – like dissolution of soil and formation of foam in combination with a good skin tolerance – in the best possible manner. Through a skilled combination of a surfactant – viewed on its own – with unfavourable skin tolerance but a very good soil removal property with a very mild, skin protecting surfactant altogether a product with good cleansing properties and the same good skin tolerances is obtained. 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.
