AI Overview

Carbopol® Ultrez 21 (or Carbomer 21) is a self-wetting, hydrophobically modified cross-linked acrylate copolymer used as a highly efficient thickener and rheology modifier. It quickly disperses to create sparkling clear gels, creams, and lotions, making it popular in personal care for its ease of processing and superior electrolyte tolerance.

Key Features and Benefits

Self-Wetting: Quickly wets in minutes without mechanical mixing, simplifying manufacturing.
High Efficiency: Provides high viscosity and excellent suspending capabilities at low dosages.
Clarity: Forms sparkling clear aqueous and hydroalcoholic gels, even at high concentrations.
Sensory and Texture: Offers a short-flow (non-drip) consistency, ideal for lotions, creams, and hand sanitizers.
Stability: Features excellent electrolyte tolerance, making it suitable for formulations containing botanical ingredients or oils.

Common Applications

Skin Care: Creams, lotions, and moisturizing gels.
Hair Care: Styling gels and shampoos.
Hygiene: Hand sanitizers (alcohol gels) and body washes.

Technical Specifications

INCI Name: Acrylates/C10-30 Alkyl Acrylate Crosspolymer.
Appearance: White powder.
Use Level: Typically used at concentrations requiring high viscosity.

It is highly regarded for its versatility in creating elegant textures in both skin care and hair care applications, often noted for its efficiency in, for instance, a 10g package from eBay or described in detail by manufacturers on UL Prospector.
