What Is Polyquaternium-10/Phosphorylcholine Glycol Acrylate Copolymer?
Polyquaternium-10/Phosphorylcholine Glycol Acrylate Copolymer is a lab made ingredient created by linking two well known cosmetic polymers: Polyquaternium-10, a modified cellulose that carries positive charges, and phosphorylcholine glycol acrylate, a molecule inspired by the skin’s own phospholipids. By combining them chemists get a lightweight polymer that attracts water, clings gently to hair or skin and forms a flexible film.
The idea to pair these two pieces came about in the early 2000s when formulators were looking for conditioners that felt lighter than traditional silicones yet offered long lasting smoothness. Cellulose derivatives had the conditioning ability but needed extra moisture retention, while phosphorylcholine units were known for their water loving, skin friendly nature. Grafting the two together answered both needs and quickly caught the attention of hair-care and skin-care brands.
Manufacturing starts with sustainably sourced wood pulp, which is turned into cellulose and then chemically quaternized to make Polyquaternium-10. In a separate step phosphorylcholine glycol acrylate is synthesized from simple petrochemical feedstocks. The two components are then joined through controlled free radical polymerization, yielding a clear, ready-to-use solution or powder.
You will most often see this copolymer in rinse-off and leave-in hair conditioners, moisturizing shampoos, styling creams, hydrating facial masks, light gel creams, after-sun lotions and soothing serums. Brands favor it when they want a silky finish without heavy oils or silicones.
Polyquaternium-10/Phosphorylcholine Glycol Acrylate Copolymer’s Cosmetic Benefits/Uses
This ingredient brings several perks to a formula thanks to its multifunctional nature
- Film Forming: Leaves a thin, breathable coating on skin or hair that locks in moisture and protects against environmental stress
- Hair Conditioning: Neutralizes negative charges on hair, reduces static, improves detangling and imparts a smooth, soft feel
- Humectant: Attracts and binds water, helping products keep skin and hair hydrated for longer
- Emollient: Gives a silky glide during application, making creams and lotions feel smoother and more luxurious
Who Can Use Polyquaternium-10/Phosphorylcholine Glycol Acrylate Copolymer
This copolymer is generally suitable for all skin types. Dry and dehydrated skin benefit from its water binding ability, while oily and combination skin appreciate that it feels light and non greasy. Sensitive skin usually tolerates it well because it is non reactive and free of common allergens. It is also mild enough for use on the scalp and color treated hair.
The ingredient is plant derived or fully synthetic with no animal sourced components, so it meets vegan and vegetarian standards. It is not tested on animals when sourced from suppliers that follow modern cosmetic regulations, but shoppers should still check the finished brand’s cruelty free policy.
No data points to specific concerns for pregnant or breastfeeding women. Still, this is not medical advice and anyone expecting or nursing should show the full ingredient list of every product to a qualified health professional before regular use.
The copolymer does not make skin more sensitive to sunlight, so it is safe for daytime wear and pairs well with sunscreen. It is also odorless and compatible with most preservatives and active ingredients, which makes it easy to slot into multi step routines.
Potential Side Effects/Adverse Reactions
Side effects and reactions to the topical use of Polyquaternium-10/Phosphorylcholine Glycol Acrylate Copolymer can vary from person to person. The issues listed below are possible but uncommon when the ingredient is used at customary amounts in well formulated products.
- Mild skin irritation such as redness or itching, typically in very sensitive individuals
- Contact dermatitis in people already allergic to quaternary ammonium compounds
- Eye stinging or watering if the product accidentally gets into the eyes
- Build up on hair after frequent use, which may leave strands feeling weighed down until shampooed
If any negative reaction occurs stop using the product immediately and seek guidance from a healthcare professional.
Comedogenic Rating
Rating: 0 / 5. Polyquaternium-10/Phosphorylcholine Glycol Acrylate Copolymer is water soluble and forms a light breathable film that rinses away easily. It is not oily, waxy or fatty so it does not trap sebum in pores. For these reasons it is very unlikely to clog pores.
Suitable for people prone to acne or breakouts.
The only time buildup could pose a problem is when the ingredient appears in heavy leave-on formulas used without regular cleansing. In normal daily use most users will not notice any pore congestion.
Summary
Polyquaternium-10/Phosphorylcholine Glycol Acrylate Copolymer acts as a film former, hair conditioner, humectant and emollient. The positive charges in the Polyquaternium part stick to hair or skin, smoothing cuticles and reducing static, while the phosphorylcholine side grabs water and keeps the surface hydrated. Together they leave a silky feel without greasiness.
It is not as famous as silicones or hyaluronic acid yet it pops up in a fair number of modern shampoos, conditioners and lightweight gel creams because formulators like its balance of slip and breathability.
Current data shows it is safe for nearly all users with only rare irritation. As with any new cosmetic ingredient it is wise to patch test a small area first to make sure your skin agrees.
