Adipic Acid/Diglycol Crosspolymer

What Adipic Acid/Diglycol Crosspolymer is & what it does

Trimethylpentanediol/Adipic Acid/Glycerin Crosspolymer is a synthetic film-forming polymer made by crosslinking trimethylpentanediol, adipic acid, and glycerin. In skincare and sunscreen formulas it acts as a film former and texture modifier, helping spread the product evenly and leave a smooth, flexible finish on the skin. A notable property is that it can improve the water resistance and wear of a film, which is useful in long-lasting and sunscreen products.

Is Adipic Acid/Diglycol Crosspolymer safe?

Adipic Acid/Diglycol Crosspolymer is a synthetic polymer used as a texture and film-forming agent, and it is generally considered safe at the levels used in cosmetics. Large polymer molecules like this tend to stay on the skin's surface rather than being absorbed. As always, patch testing a new product is sensible for sensitive skin.

What does Adipic Acid/Diglycol Crosspolymer do in skincare?

In skincare it functions as a film former and texture agent, helping create a smooth, cohesive feel and supporting the structure of a formula. Polymers like this can improve spreadability and give products a more refined finish. Its effect is mostly about feel and stability rather than active skin benefits.

Is Adipic Acid/Diglycol Crosspolymer natural or synthetic?

Adipic Acid/Diglycol Crosspolymer is a synthetic polymer made by reacting smaller building blocks in a controlled manufacturing process. It is not plant or animal derived. This synthetic origin gives it the consistent, predictable properties needed for stable formulas.
