What Is Acrylates/Tridecyl Acrylate/Triethoxysilylpropyl Methacrylate/Dimethicone Methacrylate Copolymer?
Acrylates/Tridecyl Acrylate/Triethoxysilylpropyl Methacrylate/Dimethicone Methacrylate Copolymer is a lab made polymer created by linking together several smaller building blocks: tridecyl acrylate for flexibility, triethoxysilylpropyl methacrylate for strong adhesion to skin, dimethicone methacrylate for a silky silicone feel and extra slip, and small amounts of acrylic or methacrylic acid esters to tie everything together. Chemists first explored this kind of hybrid molecule in the late 1990s when brands wanted makeup that felt light yet stayed put. The polymer is produced through a controlled free radical process in large stainless-steel reactors; once the reaction is complete the finished material is purified, dried and blended into a liquid or powder form that is easy to add to formulas.
Because it combines the staying power of acrylates with the softness of silicones, this copolymer turns up in many leave-on products. You will see it in facial moisturizers, primers, long-wear foundations, tinted sunscreens, BB and CC creams, smoothing hair serums, styling creams and even some sheet masks where it helps the essence cling better to the skin.
Acrylates/Tridecyl Acrylate/Triethoxysilylpropyl Methacrylate/Dimethicone Methacrylate Copolymer’s Cosmetic Benefits/Uses
In formulas this ingredient serves one key role: skin conditioning. By forming a thin flexible film on the surface it makes skin feel softer and smoother, enhances spreadability and boosts the lasting power of pigments and other actives.
Who Can Use Acrylates/Tridecyl Acrylate/Triethoxysilylpropyl Methacrylate/Dimethicone Methacrylate Copolymer
This film-forming polymer works for most skin types including oily, combination and dry because it is lightweight, non-greasy and does not leave a tight feel once it sets. People with very sensitive or eczema-prone skin may want to watch for any stinging since acrylate chemistry can bother an already compromised barrier, but the chance is low in well-made products.
The ingredient is synthetic and made from silicone and petrochemical building blocks, so it contains no animal-derived material. That makes it suitable for vegans and vegetarians.
Current data show no evidence of harm during pregnancy or breastfeeding because the molecules are large and stay on the surface of the skin. This is not medical advice; anyone who is pregnant or nursing should check with a healthcare professional before adding new products just to be safe.
The polymer does not make skin more sensitive to the sun, so there is no added risk of photosensitivity after use.
Potential Side Effects/Adverse Reactions
- Mild redness or itching on very sensitive skin
- Allergic contact dermatitis in individuals already reactive to acrylate resins
- Temporary clogged pores if heavy makeup layers are not fully removed
- Eye irritation if the product accidentally gets into the eyes
If any of these reactions occur, stop using the product and seek guidance from a qualified healthcare professional.
Comedogenic Rating
Rating: 1/5 – This copolymer is made of large, non-penetrating molecules that sit on the surface and create a breathable film rather than sinking into pores. Silicone segments help it glide without heavy oils and the acrylate network keeps the film flexible, both of which lower the chance of pore blockage. While any film former could trap debris if you do not cleanse properly, on its own the ingredient poses minimal comedogenic risk.
Suitable for acne-prone or breakout-prone skin in most cases.
Those using very rich or layered makeup routines should double-cleanse to remove the film completely and avoid build-up over time.
Summary
Acrylates/Tridecyl Acrylate/Triethoxysilylpropyl Methacrylate/Dimethicone Methacrylate Copolymer works as a skin-conditioning film former. It spreads into a thin flexible veil that smooths texture, softens feel and anchors pigments or actives so they last longer. The acrylate blocks supply grip, the silicone blocks add slip and softness and the silane groups help the film bond to skin.
It shows up frequently in long-wear makeup, primers and hybrid skincare formulas yet is still less talked about than classic silicones like dimethicone, so most shoppers do not recognize its tongue-twisting name even though they benefit from its performance.
Current safety data rate the polymer as low risk because its large size keeps it on the surface and it is used at modest levels, but minor irritation is possible for very sensitive users. As with any new cosmetic ingredient it is wise to patch test a product first to ensure it agrees with your skin.
