Isoamyl laurate is a chemical compound, a fatty latic acid ester obtained by the condensation of dodecanoic acid with 3-methylbutan-1-ol and derived from an isoamylol. It is industrially produced from vegetable oils and sugar.
The name defines the structure of the molecule:
The synthesis of isoamyl laurate typically involves the esterification of isoamyl alcohol and lauric acid. Here is a simplified version of the process:
The overall process can be summarised as follows:
Isoamyl alcohol + Lauric acid → Isoamyl laurate+ Water
It appears as a colourless transparent liquid. Soluble in ethanol, insoluble in water.
What it is used for and where
Moisturising substitute for silicone oil, of vegetable origin with good compatibility with most epoxy silicone oils, synthetic oils, mineral oils, vegetable oils, silicone oils of various viscosities and sunscreen.
Cosmetics
Used as a solvent, fragrance, as a conditioner in hair conditioners and masks, make-up products for sun protection. Compared to caprylic acid/triglyceride, it has better spreadability, is less sticky and provides a less greasy residual feel on the hands.
Skin conditioning agent. It is the mainstay of topical skin treatment as it has the function of restoring, increasing or improving skin tolerance to external factors, including melanocyte tolerance. The most important function of the conditioning agent is to prevent skin dehydration, but the subject is rather complex and involves emollients and humectants that can be added in the formulation.
Skin conditioning agent - Emollient. Emollients have the characteristic of enhancing the skin barrier through a source of exogenous lipids that adhere to the skin, improving barrier properties by filling gaps in intercorneocyte clusters to improve hydration while protecting against inflammation. In practice, they have the ability to create a barrier that prevents transepidermal water loss. Emollients are described as degreasing or refreshing additives that improve the lipid content of the upper layers of the skin by preventing degreasing and drying of the skin. The problem with emollients is that many have a strong lipophilic character and are identified as occlusive ingredients; they are oily and fatty materials that remain on the skin surface and reduce transepidermal water loss. In cosmetics, emollients and moisturisers are often considered synonymous with humectants and occlusives.
Food
Generally used as a flavouring agent in wine, beer.
