Acrylates/Vinyl Isodecanoate Crosspolymer

What is Acrylates/Vinyl Isodecanoate Crosspolymer?

Acrylates/Vinyl Isodecanoate Crosspolymer is a high-molecular-weight synthetic polymer created through the copolymerization of acrylate monomers and vinyl isodecanoate, then crosslinked for a three-dimensional network structure. In cosmetics, it disperses easily in water or aqueous phases, swelling to form transparent, high-viscosity gels without tackiness. This makes it ideal for serums, creams, lotions, sunscreens, and makeup products. Functionally, it builds structure in emulsions by reinforcing interfaces between oil and water phases, prevents particle settling through network entrapment, adjusts flow properties for easy spreading, and deposits a flexible film for enhanced product performance like water resistance or even coverage. Its electrolyte tolerance supports inclusion of salts or actives without viscosity loss, contributing to robust, sensorially pleasing formulations across pH ranges.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Emulsion stabilizer

Improves emulsion robustness by preventing droplet coalescence and phase separation, often by thickening, structuring, or strengthening the interfacial layer.

Suspending agent

Keeps insoluble particles (pigments, beads, actives) evenly dispersed by increasing viscosity or forming a network, preventing settling and separation.

Viscosity controlling agent

Adjusts thickness to the desired level for stability and usability, improving dispensing, suspension, and texture across many formulation types.

Film former

Creates a continuous film on skin or hair to improve wear, water resistance, transfer resistance, shine, or hold in sunscreens, makeup, and styling products.

Benefits

Stabilizes emulsions to maintain product consistency over time.

Controls viscosity for smooth, easy-to-apply textures.

Suspends particles evenly, ensuring uniform active delivery.

Who It's For

Who May Benefit	Who Should Avoid
Users seeking lightweight, non-greasy skincare textures.	People with rare sensitivities to acrylate polymers.
Individuals with oily or acne-prone skin due to its non-comedogenic nature.	Those preferring entirely natural or plant-derived ingredients.
Those using sunscreens or makeup for improved wear and stability.	Individuals experiencing irritation from similar synthetic thickeners.
