Ingredient review
Sodium Tauride Acrylates Copolymer
INCI: SODIUM TAURIDE ACRYLATES/ACRYLIC ACID/ACRYLONITROGENS COPOLYMER
A gentle film-forming polymer that helps products spread smoothly and leaves a comfortable, non-sticky finish.
In plain English
This is a synthetic polymer that forms a thin, flexible film on your skin or hair. It helps other ingredients spread evenly and gives products a silky, non-tacky feel. Think of it like a lightweight, invisible shield that helps your skincare or haircare stay put without feeling heavy or sticky.

Quick decision guide
Useful, but context matters
Sodium Tauride Acrylates 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 Sodium Tauride Acrylates 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 polymer created by copolymerizing tauride acrylates, acrylic acid, and acrylonitrogens. It is designed to form a uniform, flexible film when applied to skin or hair.
How it works
When applied, the polymer chains spread out and link together as the water evaporates, creating a thin, breathable film. This film helps hold other ingredients in place, improves the texture of the product, and can provide a slight smoothing or tightening effect without being occlusive.
Pros
Non-sticky finish
Leaves skin and hair feeling smooth and silky without the tacky residue common with some other film formers.
Flexible film
The film it creates moves with your skin or hair, so it doesn't crack or feel stiff, making it comfortable for daily use.
Cons and cautions
Synthetic origin
As a fully synthetic polymer, it may not be preferred by those seeking natural or organic skincare routines.
Limited research on long-term effects
While generally considered safe, there is less independent research on this specific polymer compared to more common ingredients.
Best for
- Anyone looking for a non-sticky finish in serums or moisturizers
- People who want a lightweight film for sunscreens or makeup primers
Use caution if
- Those with known sensitivity to synthetic polymers (rare)
- Individuals seeking 100% natural or organic formulations
Usage tips
Safety summary
Sodium Tauride Acrylates Copolymer is considered safe for use in cosmetics at typical concentrations. It has a low irritation and comedogenic risk, making it suitable for most skin types. Rare cases of sensitivity may occur.
Research notes
Safety assessments rely on general polymer toxicology and industry data. No significant adverse effects have been reported in cosmetic use. Independent peer-reviewed studies are limited, but the ingredient is widely accepted by regulatory bodies.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Serums, Moisturizers, Sunscreens, Styling Gels, Masks
- Environmental note
- As a synthetic polymer, its biodegradability varies by formulation. Some versions are designed to be more environmentally friendly, but it is not inherently biodegradable.
Good to know
- This polymer is often used in combination with other film formers to fine-tune texture and feel.
- It is considered biodegradable in some formulations, but check individual product claims.
