Ingredient review
Acrylamide/Acryloyldimethyltaurate/Acrylic Acid Copolymer
INCI: ACRYLAMIDE/SODIUM ACRYLOYLDIMETHYLTAURATE/ACRYLIC ACID COPOLYMER
A safe, effective synthetic thickener that gives water-based products a smooth, non-sticky feel without clogging pores.
In plain English
This ingredient is a synthetic polymer — a large molecule made of repeating units — that helps thicken water-based products like moisturizers and serums. It creates a smooth, silky texture and helps stabilize the formula so ingredients don't separate. Think of it like a gentle, invisible net that holds the product together without leaving a heavy or greasy feel on your skin.
Quick decision guide
Useful, but context matters
Acrylamide/Acryloyldimethyltaurate/Acrylic Acid 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.
- Step 1Start with the score, then check the irritation and clogging risk before judging Acrylamide/Acryloyldimethyltaurate/Acrylic Acid Copolymer.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- 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
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A high-molecular-weight synthetic copolymer made from acrylamide, sodium acryloyldimethyltaurate, and acrylic acid. It is designed to thicken and stabilize water-based cosmetic formulations.
How it works
When added to water, the polymer chains swell and entangle, increasing the viscosity of the product. This creates a smooth, gel-like texture that helps suspend other ingredients (like oils or powders) and improves the product's spreadability and feel on the skin.
Pros
Smooth, non-sticky feel
Unlike some thickeners that leave a tacky residue, this copolymer creates a silky, lightweight texture that absorbs quickly without feeling heavy.
Excellent stabilizer
It helps keep oil and water phases mixed, preventing your product from separating or becoming watery over time.
Cons and cautions
Synthetic origin
It is made in a lab, so it may not be suitable for people who prefer 100% natural or plant-based skincare ingredients.
Potential stickiness at high levels
If used in very high concentrations (above 2-3%), the product can feel slightly tacky or sticky on the skin.
Best for
- Anyone who prefers lightweight, non-greasy moisturizers or serums
- People with oily or combination skin looking for a matte finish
Use caution if
- Those who strictly avoid synthetic ingredients in their skincare
Usage tips
Safety summary
This copolymer is considered safe for topical use in cosmetics. It has low irritation and comedogenic potential, and no significant safety concerns have been identified at typical concentrations.
Research notes
Safety assessments by the Cosmetic Ingredient Review (CIR) panel and other regulatory bodies support the use of acrylate copolymers in cosmetics. Studies indicate low skin irritation and sensitization potential.
Common label clues
- Typical concentration
- 0.1% to 2%
- Regulatory status
- Approved for use in cosmetics by the FDA and the European Commission. The Cosmetic Ingredient Review (CIR) panel has reviewed similar acrylate copolymers and found them safe at typical use levels.
- Common uses
- Moisturizers, Serums, Sunscreens, Gels, Creams
- Environmental note
- As a synthetic polymer, it is not biodegradable. However, it is used in very small amounts and is not known to accumulate in the environment at concerning levels.
Good to know
- This ingredient is often used in gel-based sunscreens to improve spreadability and water resistance.
- It is considered safe by major regulatory bodies when used within typical cosmetic concentrations.
