Novel dendritic polymer - film forming agent for cosmetic additives

Dendritic polymers, known as the "fourth generation of new polymer materials", have attracted wide attention from the scientific community and industry. The novel features of the material are: highly branched molecular structure, a large number of surface functional groups, the presence of cavities within the molecule, the monodisperse molecular weight distribution, and the molecular size of nanometer. The structural characteristics of dendritic molecules make them have unique properties: excellent dissolution and dispersion properties, low melt viscosity and solution viscosity, not easy to crystallize, easy to form films, showing unparalleled nano characteristics.
Dendritic polymers with hydroxyl functional groups are used in cosmetics for local beauty or skin, which can enhance the film formation of cosmetics on the skin surface and have good sensory properties, non-toxic side effects and easy degradation.

Product performance
Dendritic polymer as a cosmetic film forming agent has the following excellent properties:
• Improve the uniformity of the coating layer;
• Soften and protect skin;
• Improve adhesion;
• Prevent makeup from falling;
• Promotes cleansing of the skin.
Basic physical properties

Properties of dendritic polymers as cosmetic additives
Dendritic polymer with hydroxyl functional group as a cosmetic film forming agent can make cosmetics more easily form a uniform film on the skin surface and have better sensory properties than cosmetics prepared with other additives. The following table is the evaluation of the three formulations of cosmetics coated on the glass plate after drying and peeling off the film:
Table 1 Analysis: A, B and C in the figure are the comparison of three different formulations of cosmetics: C is the control group (no dendritic polymer is added), the results show that C is very difficult to remove after forming the film, that is, it is not easy to remove makeup when applied on the skin, while group A and group B add dendritic polymer in the formula, these two groups are very easy to remove and suitable for application on the skin, according to the different proportions of each component in group A and group B. Group B is one of the best formulations because it forms a rigid film that is flexible and very easy to remove, and has good sensory properties when applied to the skin;
