INCI: ADIPIC ACID/DILINOLEIC ACID/HEXYLENE GLYCOL COPOLYMER

A safe, synthetic film-former that helps makeup and sunscreen last longer without clogging pores.

beautyskincarefilm-former

In plain English

This ingredient is a type of plastic-like polymer that spreads into a thin, flexible film on your skin. It helps other ingredients stay put, resist water, and feel smooth. Think of it like an invisible, breathable shield that keeps your makeup or sunscreen from sliding off.

Quick decision guide

Useful, but context matters

Adipic/Dilinoleic/Hexylene Glycol Copolymer is generally a lower-concern ingredient when the full formula suits your skin.

Plain-English read

Treat this as a practical screening step before you compare products that contain this ingredient.

  1. Step 1Start with the score, then check the irritation and clogging risk before judging Adipic/Dilinoleic/Hexylene Glycol Copolymer.
  2. Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
  3. Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.

Score terms in plain English

Irritation risk

low

Less likely to sting, burn, or bother most users, though sensitive skin can still react.

Clogging risk

low

Less likely to feel heavy or contribute to clogged pores for most skin types.

Evidence level

moderate

There is useful support, but formula details and claim strength still matter.

What it is

A synthetic copolymer made from adipic acid, dilinoleic acid, and hexylene glycol. It is designed to form a continuous, flexible film on the skin or hair.

How it works

When applied, the polymer molecules link together into a thin, even layer. This layer physically holds pigments, UV filters, or other active ingredients in place, improving adhesion and water resistance without feeling heavy or sticky.

Pros

Long-lasting wear

Helps makeup and sunscreen stay on for hours, even in humid or sweaty conditions.

Non-comedogenic

Unlikely to clog pores, making it suitable for acne-prone skin when used in typical concentrations.

Cons and cautions

Synthetic origin

Made from petrochemical derivatives, which may be a concern for those seeking natural-only products.

Potential tightness

On very dry or sensitive skin, the film can sometimes feel slightly tight or drying.

Best for

  • Anyone wanting longer-lasting makeup or sunscreen
  • People with oily or combination skin who need extra staying power

Use caution if

  • Those with extremely dry or compromised skin barriers who prefer minimal film-formers

Usage tips

Apply over moisturizer to prevent any potential dryness from the film.
Use a gentle oil-based cleanser or micellar water to fully remove products containing this polymer.

Safety summary

Considered safe for cosmetic use at typical concentrations. Low irritation and comedogenic potential. No significant safety concerns reported in regulatory reviews.

Research notes

Limited independent studies on this specific copolymer, but film-forming polymers in its class are well-tolerated. Safety is supported by industry usage and regulatory approvals.

Common label clues

Typical concentration
0.5% to 5%
Regulatory status
Approved for use in cosmetics globally, including by the U.S. FDA and EU CosIng database, with no known restrictions at typical use levels.
Common uses
Sunscreens, Long-wear makeup, Water-resistant formulas
Environmental note
As a synthetic polymer, it is not biodegradable. However, it is used in low concentrations and is not known to bioaccumulate.

Good to know

  • Often listed near the end of ingredient lists because it is used in small amounts.
  • Commonly found in 'waterproof' or 'long-wear' labeled products.
