What it is
Polyglyceryl-2 Isostearate/Dimer Dilinoleate Copolymer is a synthetic copolymer combining polyglyceryl, isostearate, and dimer dilinoleate units to create a surfactant with strong affinity for oils and pigments. It is used to emulsify and disperse particles, giving even color and a smooth, non-greasy application. It is common in sunscreen sticks, tone-up products, and lip oils where stable pigment dispersion is needed.
Safety & warnings
Polyglyceryl-based emulsifiers are generally well tolerated and considered mild, with a low irritation and sensitization profile. This copolymer is not a known fragrance allergen and is not typically associated with comedogenicity at use levels.
Origin & sourcing
Synthetic, built from polyglycerol esterified with isostearic acid and dimer dilinoleic acid (a dimerized fatty acid), the latter components being derived from plant-sourced fatty acids.
Questions everyone asks
What does this copolymer do?
It emulsifies and disperses oils and pigments to give even color and a smooth feel, especially in sticks, tone-up sunscreens, and lip oils.
Is it a harsh surfactant?
No. Polyglyceryl-based emulsifiers are generally regarded as mild and well tolerated.
