What Is Pentaerythrityl Tetraethylhexanoate Crosspolymer?
This higher-molecular-weight crosslinked variant of Pentaerythrityl Tetraethylhexanoate provides thickening and texturizing properties in addition to the emolliency of the base ester. The crosslinked structure creates a gel-like network that adds viscosity, improves suspension of particles, and enhances product stability — while maintaining the characteristic light, dry skin feel of the ethylhexanoate ester family.
Key Skin Benefits
+ Thickening — adds viscosity without waxy heaviness
+ Particle suspension — keeps pigments and powders evenly dispersed
+ Light sensory — maintains the dry-touch feel of ethylhexanoate esters
+ Emulsion stabilization — improves formula shelf stability
Pros
+ Thickens while maintaining light skin feel — rare combination
+ Good particle suspension for makeup and sunscreens
+ Synergistic with other thickeners
+ Suitable for gel-cream textures popular in Asian markets
Cons
− Synthetic crosslinked polymer — not biodegradable
− Higher cost than base tetraethylhexanoate
− Can be difficult to disperse uniformly without proper equipment
− Limited supplier options for this specific crosspolymer
