What Is Polyacrylate Crosspolymer-3?
Polyacrylate Crosspolymer-3 is a lab-made copolymer built from butyl acrylate, PEG-10 acrylate, PPG-6 acrylate and dimethylacrylamide that are chemically joined, then crosslinked with PEG-23 diacrylate to create a three-dimensional network. The result is a lightweight, water-dispersible powder or gel-like material that behaves as a flexible yet durable film former.
The ingredient was developed in the late 1990s when formulators looked for styling polymers that could deliver strong hold without the flaking sometimes linked to older resins. By tweaking the mix of acrylate building blocks and adding polyether segments, chemists achieved a polymer that keeps hair in place while remaining touchable and easy to rinse out.
Manufacturing begins with carefully measured monomers dissolved in water or solvent. Under controlled heat and the help of an initiator, the monomers link into long chains. PEG-23 diacrylate is then introduced so parts of the chains tie together, locking the structure in place. The finished polymer is filtered, dried or neutralised and finally milled to the desired particle size.
You will most often find Polyacrylate Crosspolymer-3 in hair gels, styling creams, mousses, pomades and aerosol sprays. Its film-forming nature also makes it a handy addition to certain eyebrow gels and clear mascaras where light hold is needed.
Polyacrylate Crosspolymer-3’s Cosmetic Benefits/Uses
In cosmetic formulas Polyacrylate Crosspolymer-3 serves a single but important purpose that brings several advantages to styling products.
Hair fixing: The polymer forms an invisible film around each hair strand, providing lasting hold so styles stay in place even in humid conditions. Because the film is flexible, hair does not feel stiff or crunchy, and it can be brushed out without heavy flaking. The ingredient also helps tame flyaways, adds slight gloss and improves overall style longevity while remaining easy to wash out with regular shampoo.
Who Can Use Polyacrylate Crosspolymer-3
Because this ingredient is a high-molecular-weight film former that stays mostly on the surface, it is considered compatible with all skin and scalp types, including oily, dry, sensitive and combination. It does not penetrate or disturb the skin barrier so it rarely triggers issues for reactive skin. There are no known concerns for darker skin tones or conditions such as eczema or psoriasis, although anyone with an existing inflammatory condition should monitor how their skin feels after use.
Polyacrylate Crosspolymer-3 is fully synthetic and contains no animal-derived matter, making it suitable for vegans and vegetarians. It is also cruelty free in itself, though the finished product’s status depends on the brand’s overall testing policy.
Current safety data show no specific risks for pregnant or breastfeeding women when the ingredient is used in rinse-off or leave-on hair products. This is not medical advice and anyone who is pregnant or nursing should run any cosmetic product past a healthcare professional to be on the safe side.
The polymer does not cause photosensitivity and will not make skin or hair more prone to sunburn. It is colour-safe for treated hair and compatible with most common styling aids like silicones, proteins and humectants.
Potential Side Effects/Adverse Reactions
Reactions to topical Polyacrylate Crosspolymer-3 vary from person to person. The effects below are possible but highly unlikely for the average user when the ingredient is included at normal use levels in a well-formulated product.
- Mild scalp or skin irritation such as redness or itching
- Allergic contact dermatitis in individuals sensitive to acrylate compounds
- Eye irritation if the product is accidentally rubbed or sprayed into the eyes
- Respiratory discomfort if large amounts of aerosolised particles are inhaled during application
- Product build-up on hair leading to a weighed-down feel if not cleansed regularly
If you notice any of the above reactions stop using the product and consult a healthcare professional for guidance.
Comedogenic Rating
Rating: 0 / 5
Polyacrylate Crosspolymer-3 is a very large water-loving molecule that sits on the surface of hair or skin rather than soaking into pores. Because it is not an oil and does not form greasy residues the risk of clogged follicles is practically nil. Its light film can be shampooed or cleansed away easily which further reduces any chance of pore blockage.
That makes this ingredient suitable for people prone to acne or breakouts.
As with any styling polymer build-up could occur if heavy products are layered and cleansing is infrequent, so regular washing is advised to keep scalp and hair fresh.
Summary
Polyacrylate Crosspolymer-3 is a synthetic styling polymer that forms a flexible film on hair giving long-lasting hold, frizz control and a touch of shine while remaining easy to brush out and rinse away. Its popularity is moderate rather than widespread, mainly turning up in mid-range gels, creams and sprays where formulators want reliable performance without flaking.
Safety data show it to be low risk for irritation, allergy or pore blockage, and it is vegan friendly and suitable for all hair and skin types. As with any new cosmetic it is smart to patch test a small area first to be on the safe side before using a full-size product.
