【 functions 】As a solvent, such as applied in the field of personal care products. Isoamyl diol consists of isoprene and two molecules of water, in one of the molecular structure and a tertiary alcohol, commonly used in the field of cosmetics moisturizing agent, antibacterial agent, solubilizer and emollients, is commonly used as a solvent in other fields.Isoamyl diol in the application of skin care, face film products1, because of its features is soluble in water and soluble in oil, and have excellent slip may just as well to the skin and moisturizing effect, commonly used for skin care, facial mask product of emollients solubilizing agent and solvent, help oil soluble ingredients dissolved in water-based formula, so as to improve transparency.2, because of its no irritating to skin, eyes and mucosa and has good chemical stability and oxidative stability, is often used in maternal and infant and mild skin care products, such as eye mask.3, due to its good moisturizing effect, often used in skin care, face moisturizer in the product.4, since it has excellent antimicrobial properties, are often used to need no preservatives added to protect skin to taste, the mask.
1. Compared with other polyols, isoamyl alcohol is soluble in water, and has excellent oil compatibility. It is miscible with benzene and other non-polar solvents, and has a refreshing and non-greasy moisturizing feeling, so it is often used in cosmetic solvents. 2, it is very good for skin and eye oil missolubility, and has a good solubility with water, so it is often used as one of the main raw materials of makeup products, especially suitable for eyes and sensitive skin discharge makeup products. 3, give the skin smooth and non-greasy feeling, improve the refractive index of gloss (1.443). Good wetting dispersion :TiO2 (4/5), FeO2(1/1). Helps to produce a sticky foundation (up to 80-85℃) and improve the resistance to powder drop. Application of isopentadiol in hair care products 1, because it has the characteristics of fat structure and practical tests, the gloss of combing has a better moisturizing effect on hair. 2. Damaged area, has a good repair effect on the hair surface, often used in hair conditioner, is the main component of well-known cosmetics brands.
