In plain English

Adipic Acid/Diglycol Crosspolymer is a man-made ingredient that acts like tiny, absorbent beads. When added to creams, powders, or foundations, it soaks up excess oil and gives the product a smooth, silky feel. It also helps other ingredients spread evenly on your skin and can make the finish look more matte. Think of it as a texture helper that makes your makeup or lotion feel nicer and last longer without making your skin greasy.

Quick decision guide

Useful, but context matters

Adipic Acid/Diglycol Crosspolymer 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 Acid/Diglycol Crosspolymer.
  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 crosspolymer created by reacting adipic acid with diglycol. It forms a network of tiny particles that can absorb oil and water, and it is commonly used as a texture modifier and oil-control agent in cosmetics.

How it works

In a cosmetic product, the crosspolymer particles act like sponges, absorbing excess sebum (skin oil) and moisture from the formula. This helps reduce shine, gives a matte finish, and prevents the product from feeling heavy or sticky. It also helps other ingredients spread more evenly and can improve the product's stability over time.

Pros

Excellent oil control

Absorbs excess sebum, helping to reduce shine and keep makeup looking fresh longer, especially beneficial for oily skin types.

Improves product feel

Gives a silky, velvety texture that makes creams and powders glide on smoothly, enhancing the overall user experience.

Cons and cautions

Synthetic ingredient

Made from petrochemicals, which may be a concern for those seeking natural or plant-based alternatives.

Potential for dryness

In high concentrations, it can absorb too much moisture, potentially leaving dry skin feeling tight or flaky.

Best for

  • People with oily or combination skin looking for a matte finish
  • Anyone who wants a smoother, more luxurious texture in their makeup or skincare

Use caution if

  • Those with very dry or dehydrated skin, as it may emphasize dryness if used in high amounts

Usage tips

Look for this ingredient in primers and foundations if you have oily skin and want a matte finish.
If you have dry skin, use products with this ingredient sparingly or layer with a hydrating moisturizer underneath.
It works well in powder formulations for touch-ups throughout the day to control shine.

Safety summary

Adipic Acid/Diglycol Crosspolymer is widely regarded as safe for cosmetic use. It has low irritation and comedogenic potential, making it suitable for most skin types. No significant safety concerns have been raised by regulatory bodies or dermatological research.

Research notes

Research on this specific crosspolymer is limited, but it is chemically similar to other safe cosmetic polymers. Its safety is supported by its widespread use and lack of adverse reports. The Cosmetic Ingredient Review (CIR) panel has reviewed related polymers and found them safe as used.

Common label clues

Typical concentration
1% to 10% depending on the product type
Regulatory status
Approved for use in cosmetics in the US (FDA), EU, and other major markets. It is not restricted and is considered safe at typical usage levels.
Common uses
Foundations, Powders, Primers, Sunscreens, Moisturizers
Environmental note
As a synthetic polymer, it is not biodegradable and may persist in the environment. However, it is used in small amounts and is not known to bioaccumulate.

Good to know

  • Adipic Acid/Diglycol Crosspolymer is considered non-comedogenic, meaning it is unlikely to clog pores.
  • It is often used in combination with other powders like silica or talc to achieve the desired texture.
