Adipic Acid/Neopentyl Glycol Crosspolymer

Adipic Acid/Neopentyl Glycol Crosspolymer is a synthetic polymer — a long-chain molecule created by linking adipic acid (a dicarboxylic acid) with neopentyl glycol. It forms a three-dimensional network structure that can absorb and hold oils whilst maintaining a smooth, uniform texture.In skincare, this ingredient serves primarily as a texture modifier and stabiliser. It helps powders flow smoothly, controls viscosity in liquids, and can reduce the greasy feel of formulations without compromising efficacy or comfort.

The crosspolymer's three-dimensional structure acts like a sponge, capable of absorbing and trapping moisture and oils. When incorporated into a formulation, it helps distribute active ingredients evenly whilst controlling how much oil the product absorbs, which affects both feel and longevity on the skin.In powders, it improves flow and reduces caking. In liquids and creams, it can thicken the formula and reduce greasiness without adding weight, making the product more elegant and easier to apply.

This ingredient is used by formulators, not by consumers directly — it appears in finished products. If you are using a product containing it, apply as directed by the brand. Its presence should make the product feel more comfortable and stable; if texture or finish changes over time, storage conditions (heat, humidity, light) may have affected the formulation.

Generally well-tolerated and recognised as safe in cosmetics by major regulatory bodies. Rarely causes irritation or sensitisation, though those with very reactive skin should monitor their response to any new formulation.
