What it is
Poly C10-30 Alkyl Acrylate is a synthetic polymer formed from esters of acrylic acid with long-chain (C10 to C30) fatty alcohols. It controls viscosity and helps stabilize emulsions, and it can form a light film that improves the texture and sensory feel of a product. Because the long alkyl side chains are oil-loving while the acrylate backbone interacts with water, the polymer helps keep oil and water phases evenly combined for a smooth, uniform consistency. It appears in both mineral and organic sunscreens as well as creams, serums, and mascaras.
Origin & sourcing
It is a fully synthetic polymer produced by polymerizing acrylic acid esters of C10 to C30 fatty alcohols. The fatty side chains give it its oil-compatibility, while the polymer backbone provides thickening and stabilizing performance.
Questions everyone asks
What is this ingredient for?
It thickens the formula, helps keep the oil and water phases stable, and forms a light film that improves how the product feels on skin.
Is it a UV filter?
No. It is a texture and stability polymer and provides no sun protection by itself.
Is it natural?
No, it is a synthetic acrylate polymer made from acrylic acid esters of long-chain fatty alcohols.
