Formula IngredientFilm-Forming Agent

Polyacrylate-13

INCI: Polyacrylate-13

Polyacrylate-13 is a synthetic copolymer composed of acrylic acid, acrylamide, sodium acrylate, and sodium acryloyldimethyltaurate monomers. It functions primarily as a film-forming agent and rheology modifier, creating a smooth, silky texture in formulations. It is almost always used as part of a thickener-emulsifier trio alongside Polyisobutene and Polysorbate 20, providing excellent stabilising and emulsifying capabilities.

Is Polyacrylate-13 safe? Key considerations

Can Polyacrylate-13 cause irritation?

Low Risk

Non-irritating at 3% concentration in a 48-hour SIOPT study (20 subjects) per CIR safety assessment. Non-sensitizing at 5% in a Human Repeat Insult Patch Test (HRIPT, 49 subjects). Listed under EU CosIng Annex III/66, indicating restricted use — formulators must comply with concentration limits specified in that Annex entry.

Does Polyacrylate-13 increase sun sensitivity?

No Risk

Polyacrylate-13 is a film-forming polymer with no photosensitising mechanism. No special sun protection precautions are required based on its presence in a formulation.

Is Polyacrylate-13 safe during pregnancy?

Caution

Specific data on the topical use of Polyacrylate-13 during pregnancy or breastfeeding is lacking. The CIR safety assessment does not flag reproductive or developmental concerns, and systemic absorption from topical use is expected to be minimal. As a precaution, pregnant or breastfeeding individuals should consult a healthcare provider. (Source: CIR Safety Assessment; Deascal ingredient profile)

How does Polyacrylate-13 work?

Polyacrylate-13 is a synthetic copolymer composed of acrylic acid, acrylamide, sodium acrylate, and sodium acryloyldimethyltaurate monomers.

Individuals with known acrylate allergy (rare; patch test recommended if acrylate sensitivity is suspected) should review the considerations above before use.
