Polyurethane-62 ●
TL;DR. This ingredient is a synthetic film-former used to create flexible, water-resistant films in makeup, hair styling, and some skin-care formats. It helps improve hold, transfer resistance, wear time, and surface feel.
What does Polyurethane-62 do in a cosmetic formula?
This ingredient is a synthetic film-former used to create flexible, water-resistant films in makeup, hair styling, and some skin-care formats. It helps improve hold, transfer resistance, wear time, and surface feel.
Is Polyurethane-62 clean?
From a clean-beauty perspective, this ingredient has friction because it is a synthetic polymer rather than a biodegradable, naturally derived material. It is generally low-irritation when fully polymerized, but some standards scrutinize residual monomers, processing aids, and polymer persistence.
Is Polyurethane-62 sustainable?
This material is typically made from petrochemical-derived building blocks and is not considered readily biodegradable. Its sustainability profile is limited by persistence after rinse-off or wear-off, especially where synthetic polymer release is a concern.
Is Polyurethane-62 COSMOS-approved?
It is not aligned with COSMOS-natural or COSMOS-organic expectations because synthetic film-forming polymers of this type are not permitted. From a Green Chemistry view, the main drawbacks are non-renewable feedstocks and limited biodegradability, even when supplied in water-based dispersions.
How does Polyurethane-62 work chemically?
The molecule is a segmented polymer containing urethane linkages, usually designed to balance hard segments for durability with softer segments for flexibility. It is commonly used as an aqueous dispersion or pre-formed polymer at low single-digit to about 10% active levels, with performance influenced by pH, neutralization state, particle size, and co-film-formers.
