Capryloyl Glycerin/Sebacic Acid Copolymer

What Capryloyl Glycerin/Sebacic Acid Copolymer is & what it does

A film-forming polymer built from glycerin and sebacic acid that holds water at the skin surface and helps a sunscreen feel smooth and cushioned. It leaves a flexible, breathable layer that supports hydration and an even finish. It is mild and non-greasy, which is why it turns up in lightweight lotions and balms.

What is Capryloyl Glycerin/Sebacic Acid Copolymer and what does it do in sunscreen?

It is a glycerin-based film-forming polymer that acts mainly as a humectant, drawing and holding water at the skin surface. In a sunscreen it leaves a thin, flexible layer that keeps skin feeling hydrated and helps the product spread and set smoothly. It contributes to a cushioned, non-greasy finish rather than to UV protection itself.

Is Capryloyl Glycerin/Sebacic Acid Copolymer safe?

Yes, for the vast majority of people. It is a large, mild polymer used at modest levels and is well tolerated on the skin. It is not a known sensitizer, and our data does not flag it as an allergen.

Does Capryloyl Glycerin/Sebacic Acid Copolymer clog pores?

Generally no. It is a water-loving film former, not a heavy oil or wax, and it is not flagged as comedogenic in our data. If a formula is breaking you out, the richer emollients and oils elsewhere in the list are far more likely the cause.

What is Capryloyl Glycerin/Sebacic Acid Copolymer on an ingredient list (INCI)?

"Capryloyl Glycerin/Sebacic Acid Copolymer" is the full INCI name you will see on the label. It usually sits in the middle of the list, alongside the other texture and hydration ingredients. It tends to appear in lightweight lotions, moisturizers, and stick formats.

Is Capryloyl Glycerin/Sebacic Acid Copolymer a humectant or an emollient?

It is primarily a humectant and film former rather than an emollient. Its job is to bind water and lay down a thin, breathable layer, so it supports hydration and finish rather than adding slip or oiliness. That makes it a good fit for formulas aiming to feel light and fresh.
