The emollients effectively provides lubrication and protection to the skin surface during use, effectively scratching it during handling and minimizing and making the skin soft, smooth and aesthetically pleasing. In bath products, emollients are described as re-fat agents, which refer to substances that improve the lipid content of the upper layers of the skin, preventing excessive skin defatting and drying.
Emollients and re-fabricants come from natural or chemically synthesized oils and fats and can be classified into polar substances (esters and triglycerides) and non-polar substances (linear and branched alkanes) Their chemical structure affects the interaction and sensory properties of the skin. As a class of substances, emollients include lipids, oils and their derivatives, fatty acid esters, lanolin derivatives, polydimethylsiloxane Alkane and organic functional group derivatives.
