What it is used for and where
Cosmetics
Plasticiser. Ingredient added to the formulation with the purpose of retaining fragrance and colour, increasing flexibility, flowability, deformability, durability of various ingredients allowing better processing.

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.

Solvent. It is a substance for dissolving or dispersing surfactants, oils, dyes, flavourings, bactericidal preservatives in solution.
