What Is Acrylates Crosspolymer-4?
Acrylates Crosspolymer-4 is a synthetic polymer—a long-chain molecule made up of acrylate building blocks linked together in a crosslinked network. It is produced through chemical synthesis rather than derived from natural sources. In skincare formulations, it functions primarily as a stabiliser and texture modifier.
This ingredient helps prevent the separation of oil and water phases in emulsions, maintains consistent product viscosity, and can form a lightweight film on the skin surface. It is used in a relatively small proportion of skincare products, typically at low concentrations.
How It Works
Acrylates Crosspolymer-4 acts as an emulsion stabiliser by positioning itself at the interface between oil and water phases, preventing them from separating. Its crosslinked structure allows it to absorb water and swell, which helps thicken the formula and maintain a stable, uniform texture.
When applied to skin, it can form a thin polymeric film that provides a smooth base and may help even out the skin's surface texture. This film is generally designed to be breathable and non-occlusive.
Clinical Evidence & References
Research on acrylate-based polymers in skincare is limited, and most available studies focus on their use in therapeutic delivery systems or wound care rather than cosmetic benefit. The ingredient's primary value in skincare is technical—stabilising formulations and improving texture—rather than delivering active skin benefits.
No significant clinical evidence demonstrates that Acrylates Crosspolymer-4 itself has inherent skin-conditioning or treatment properties. Its role is to support the delivery and performance of other active ingredients within a formulation.
How to Use
As this is a formulation ingredient rather than an active treatment, there is no specific usage guidance required. Simply use the product as directed by the manufacturer. If using multiple products, layer them according to the brand's recommendations based on texture and absorptive properties.
