Effect of emollients on skin feel properties of cosmetic formulations

Jan 29, 2019

It is well known that emollients play an important role in cosmetic formulations. They have many effects such as moisturizing the skin, lubricating the skin, protecting and softening the skin, and also increasing the residence time of the water in the skin. They also affect the skin feel properties of the cosmetic formula.

 

The molecular chemical structure of different emollient products, the polarity of the molecules, the degree of unsaturation, the presence or absence of branches in the molecular chain and the position of the branches and the size of the molecules can affect the interaction mechanism of the emollient on the surface of the skin. It is also the skin feeling performance that affects the emollient.

 

Combined with a large number of research results, the emollient properties of emollients with different chemical structures are different, and the physicochemical properties obviously affect the softness, smoothness and oily sensation of the emollient. Viscosity or physical form at body temperature also affects skin feel properties, while viscosity is lower, it is softer and smoother. Products that are solid at body temperature can make the skin sticky and rough. Unsaturated esters with branched chains have different skin feel properties, especially softness and smoothness.www.china-zhufengchem.com
