Pentaerythrityl Tetraisononanoate CAS No.: 93803-89-5
Source
Pentaerythrityl Tetraisononanoate is prepared by the esterification of pentaerythritol with a branched non-acid such as isononanoic acid. The reaction is usually carried out by alcohol esterification and involves high temperatures and the use of catalysts to form this tetraester compound.
Features
1.Chemical structure : Pentaerythrityl Tetraisononanoate is a four-esterified derivative of pentaerythritol, has a high molecular weight (about 697.04 g/mol), and is liquid at room temperature.
2.Physical properties : Its density is about 0.969 g/cm³, its melting point is low (about 12°C), and its solubility in water is very low, indicating that it is mainly a non-polar compound and is suitable for use in oily matrices.
Effect
1.Moisturizing : This compound has good moisturizing properties and can form a protective film on the skin surface to reduce water evaporation and thus maintain the moisture of the skin.
2.Skin Conditioning : Pentaerythrityl Tetraisononanoate improves the skin's texture, making it feel smoother and more comfortable.
3.Antioxidant : In some formulas, it may work with other ingredients to provide some antioxidant protection to help protect against free radical damage.
Function
1.Emulsifier : As an emulsifier, Pentaerythrityl Tetraisononanoate helps stabilize the mixing of water and oil phases to form a uniform emulsion.
2.Thickener : It increases the viscosity of skin care products, making them smoother when applied.
3.Skin protectant : In skin care products, it provides an extra barrier to protect the skin from external environmental aggressors.
Use
1.Skin care products : such as creams, lotions and essences, used to moisturize and improve skin feel.
2.Cosmetics : As an emulsifying and thickening ingredient in cosmetics such as foundation and eye shadow.
3.Personal care products : such as shampoo and conditioner, used to improve product texture and usage experience.
