AQ™ 38S is a sulfopolyester polymer that can be easily dispersed in water without the use of emulsifying agents, surfactants, or co-solvents. AQ™ 38S has a Tg of 38°C and forms films that are highly flexible. Unlike other water soluble polymers like PVP and PVOH, AQ™ 38S forms small negatively charged aggregates when dispersed in water that are much smaller than particles in typical emulsions. This allows for dispersion to be made without the need for surfactants or dispersants and rapid film formation.
Easily dispersed in water Forms flexible films Adheres well to skin Aids emulsification of organic ingredients Quick drying Adheres well to common packaging films Water/humidity resistant Neutralizing amine not needed Provides soft and smooth feel
Problems Solved
Poor water resistance of sunscreen and lotions Adhesion failure to flexible surfaces Difficult dispersion of polymers in water
Applications
AQ™ 38S, also known as Polyester-5, is an ideal film former for creams, lotions, sunscreens and other skin care applications.
AQ™ 38S is used as a film former for coatings, inks, primers, and overprints.
In ink applications AQ™ 38S is used as a binder that allows for excellent ink adhesion and rapid curing.
