Acrylates/C10-30 Alkyl Acrylate Crosspolymer

Brief Description

Acrylates/C10-30 Alkyl Acrylate Crosspolymer is a high-performance thickener, stabilizer, and emulsifier widely used in cosmetic formulations. It belongs to a family of synthetic polymers and is particularly valued for its ability to create clear, stable gels and improve product aesthetics in water-based and emulsion systems. This versatile ingredient provides a smooth texture and enhances the overall feel of cosmetic products.

INCI Name

Acrylates/C10-30 Alkyl Acrylate Crosspolymer

Appearance

White, fluffy powder or granules, easily dispersible in water.

Formulation Guidance

• How to Formulate:
  • Disperse in water with gentle stirring. Neutralize with a base (e.g., sodium hydroxide or triethanolamine) to activate its thickening properties.
  • Compatible with water, alcohols, and oils in emulsion systems.
  • Typically used in the water phase, added before emulsification.
• Usage Rate: 0.2–1.5%, depending on the desired viscosity and formulation type.

Scientific Data on Efficacy

• Benefits: This polymer effectively stabilizes emulsions, prevents ingredient separation, and creates a desirable texture. It also provides shear-thinning properties, meaning products are easy to spread but regain viscosity after application.
• Research and Studies:
  • Studies demonstrate its ability to stabilize emulsions containing volatile or reactive ingredients, ensuring long-term formulation stability (Journal of Applied Polymer Science, 2018).
  • Its role as a rheology modifier and its non-irritating properties make it ideal for sensitive-skin formulations (Cosmetic Science and Technology, 2020).

pH Stability Range

• Works best in formulations with a pH range of 5–10 after neutralization. Below pH 4, its thickening ability diminishes.

Solubility

• Dispersible in water but requires neutralization to achieve solubility and thickening action.

Why to Use It in Formulations

• Enhances product aesthetics by providing a smooth, creamy texture.
• Stabilizes both oil-in-water and water-in-oil emulsions.
• Improves viscosity and spreadability while maintaining transparency in gels and serums.
• Functions as a suspending agent for insoluble particles.

Stability Considerations

If the pH drops below 4 or rises above 10, the polymer may lose its thickening and stabilizing capabilities, leading to product instability or phase separation. Similarly, exposure to high heat during processing can degrade the polymer structure.

Possible Alternatives

• Xanthan Gum: A natural thickener suitable for organic formulations, though it may lack the clarity of Acrylates/C10-30 Alkyl Acrylate Crosspolymer.
• Carbomer: Provides similar thickening and stabilizing properties with excellent clarity in gels.
• Guar Gum (Hydroxypropyl Guar): A natural, plant-based thickener, ideal for eco-conscious formulations.
