CosIng record · function source ↗Polyurethane-84 is a urethane polymer prepared by a multi-step process. First, a polyester is made by condensing Hexanediol with Dimethyl Carbonate. The polyester is then reacted with Dimethylolpropionic Acid, Cyclohexane Dimethanol, and Saturated Methylene Diphenyl Diisocyanate to form a polyurethane. The polyurethane is neutralized with Triethylamine to make it water-dispersible, then chain extended with hydrazine and Diethylenetriamine.
European Commission · source text, with formatting normalised · CC BY 4.0CAS and EC identifiers are source references. A botanical extract, polymer or mixture may have more than one identifier; a name does not establish purity, supplier grade or sourcing.
Helps keep nails in good condition or improves their appearance.
Functions describe possible roles in a formulation. They do not establish the performance of every product containing this ingredient.
Look for the complete name POLYURETHANE-84. Similar words, derivatives and salts can refer to different ingredients.
A label usually does not tell you the supplier grade, extraction method or exact concentration of each ingredient. An individual ingredient cannot reveal the overall behaviour of a finished formula.
This entry currently documents source identity and functions. Ingredient-specific efficacy studies, sensitisation context and India-specific restrictions still need an editorial review.
Conditions below are taken from the dated CosIng annex export. A reference can cover a group of substances and specific product types. Read all conditions together; this is not an assessment of an Indian product.
