What Is Bis-Acryloyl Poloxamer 407?
Bis-Acryloyl Poloxamer 407 is a synthetic polymer created when Poloxamer 407, a well known skin-friendly surfactant, reacts with acryloyl chloride. The result is a cross-linkable network that behaves like a flexible film once it sets on the skin. Poloxamer 407 itself is a block copolymer made from polyethylene oxide and polypropylene oxide segments, prized for its mildness and water-solubility. By attaching acryloyl groups to it, chemists give the base polymer the ability to harden slightly after application, which opens new possibilities for texture and wear.
The ingredient first appeared in cosmetic research in the early 2000s, when formulators were looking for alternatives to traditional acrylic film formers that could feel lighter and rinse off easily. Because Poloxamer 407 already had a history of safe use in cleansers and contact lens solutions, modifying it rather than building a new polymer from scratch sped up its acceptance in personal care lines.
Manufacturing involves dissolving Poloxamer 407 in an organic solvent, then slowly adding acryloyl chloride in the presence of a mild base to neutralize by-products. After purification and solvent removal, the viscous polymer is dried into a powder or thick syrup that can be dispersed in water or oils during the final product mix stage.
You will most often find Bis-Acryloyl Poloxamer 407 in sheet masks, peel-off masks, long-wear makeup, primers, sunscreens, anti-aging serums and light moisturizing gels where a breathable film and steady emulsion are key to performance.
Bis-Acryloyl Poloxamer 407’s Cosmetic Benefits/Uses
This versatile polymer improves both how a product feels and how well it stays mixed.
- Emulsion stabilising – Keeps water and oil phases blended so lotions and creams remain smooth over their shelf life and do not split or form greasy pools on the surface
- Film forming – Creates a thin flexible layer on skin that locks in moisture, boosts wear time of pigments or sunscreens and gives a soft touch finish without tightness
Who Can Use Bis-Acryloyl Poloxamer 407
Bis-Acryloyl Poloxamer 407 is generally considered suitable for all skin types, including sensitive and acne-prone skin, because the base polymer Poloxamer 407 has a long record of gentle use. Its lightweight flexible film does not trap excessive oil so it rarely aggravates breakouts. Very dry skin may need an additional occlusive ingredient on top for optimum comfort since the film it forms is breathable rather than heavy.
The polymer is made entirely from synthetic sources with no animal-derived raw materials so it fits vegan and vegetarian lifestyles.
No data suggest that topical use poses a risk to women who are pregnant or breastfeeding when used in normal cosmetic concentrations. This information is not medical advice and anyone who is pregnant or nursing should show the full product ingredient list to a healthcare provider before adding it to a routine, just to be safe.
Bis-Acryloyl Poloxamer 407 does not make skin more sensitive to sunlight and has no known interactions with common photosensitizing actives such as retinoids or AHAs.
The ingredient is odorless and free of gluten, soy and common nut allergens which can be helpful for people managing those sensitivities.
Potential Side Effects/Adverse Reactions
Side effects and reactions to the topical application of Bis-Acryloyl Poloxamer 407 can vary from person to person. The points below list potential issues only and are unlikely to be the norm when the ingredient is formulated and used as intended.
- Mild transient stinging in freshly exfoliated or compromised skin
- Rare allergic contact dermatitis resulting in redness itching or small bumps
- Eye irritation if product migrates into the eyes before it sets
- Build-up related dullness if heavy film forming products are not cleansed thoroughly
If any discomfort swelling or persistent irritation occurs stop using the product and consult a qualified healthcare professional.
Comedogenic Rating
Rating: 0 / 5
Bis-Acryloyl Poloxamer 407 is a high-molecular weight polymer that sits on the skin as a breathable water-soluble film rather than seeping into pores or adding extra oils. It has no fatty acids or waxes that could block follicles which is why it earns the lowest possible comedogenic score. This makes it a safe pick for people who are prone to acne or frequent breakouts. Because it rinses away easily with regular cleansing there is little risk of residue build-up contributing to clogged pores over time.
Summary
Bis-Acryloyl Poloxamer 407 works as an emulsion stabiliser and a film former. Its block-copolymer backbone keeps water and oil phases blended so creams stay uniform while the acryloyl groups let it set into a light flexible layer that locks in moisture and improves wear time of makeup or sunscreen. Although not as famous as silicone or vinyl polymers it has been quietly gaining popularity in sheet masks and long-wear primers where comfort and easy removal matter. Existing safety data show a very low irritation profile with virtually no comedogenicity. As with any new skincare ingredient it is wise to patch test a product containing Bis-Acryloyl Poloxamer 407 before full-face use to confirm personal tolerance.
