Application of carbomer in pharmacyWhat is the composition of carbomer?

Details:

We all know the function of carbomer. This ingredient is often used in our daily cosmetics. It has good performance and can produce high viscosity in a small amount. For example, we usually use skin care products to add only 0.2% of the amount of emulsion can have a good thickening effect, but in gel cream cream, the amount of use will increase relatively more in order to achieve good results.

What is the composition of carbomer Why does it have such a good thickening effect From the appearance, it is a white loose powder with strong moisture absorption. It is composed of polyalkyl sucrose or polyalkyl pentaerythritol and acrylic acid cross-linked polymer (acrylic acid or acrylate).

In the case of dry powder, the carbon chain of acrylic acid molecule is relatively closely aggregated. Once dissolved in water, its molecules will slowly disperse and form hydrated molecules with water molecules. At this time, the closely connected carbon chains will disperse, resulting in high viscosity. The larger the expansion of hydrated molecules, the greater the viscosity.

However, water can not fully unfold the molecules, and it needs the addition of some neutralizers to achieve a good unfolding state, such as sodium hydroxide or green amine. If carbomer is not dissolved with water but with polyhydroxy alcohol or polyethyl solvent, it can also produce strong thickening and suspension through the hydrogen bond between carbomer molecule and solvent without adding any other neutralizer.
