Product Overview: Carbomer 940 Polymer
Carbomer 940 Powder is a high-molecular-weight, lightly cross-linked polyacrylic acid polymer. Synthesized through the copolymerization of acrylic acid and allyl sucrose or allyl pentaerythritol, this highly efficient rheology modifier is recognized for its exceptional thickening, suspending, and emulsion-stabilizing capabilities.
- Product Name: Carbomer 940 Polymer
- CAS Number: 9007-20-9
- Chemical Nature: Cross-linked polyacrylic acid (Acrylic crosslinking resin)
- Carboxylic Acid Group (-COOH) Content: 56.0% – 68.0%
- Appearance: Fluffy, white, hygroscopic powder
- Grade: Food Grade / Cosmetic Grade / Pharmaceutical Grade
- Testing Method: Potentiometric titration
Functional Mechanism and Physicochemical Properties
In its dry state, Carbomer 940 is an acidic, low-viscosity powder. However, when dispersed in water and subsequently neutralized, the polymer chains uncoil and repel each other due to the ionization of the carboxylic acid groups. This dramatic expansion results in a massive increase in viscosity, yielding a crystal-clear, highly stable, and elegant gel matrix.
- Rheology Modification: Provides exceptional short-flow and long-flow rheological profiles, optimizing the sensory feel of aqueous and hydroalcoholic systems.
- Suspension & Stabilization: Effectively suspends insoluble ingredients (such as exfoliants, pigments, or active compounds) and stabilizes oil-in-water emulsions, preventing phase separation.
- Optical Clarity: Forms highly transparent gels, making it ideal for clear serums, ultrasound gels, and aesthetic formulations.
- Sensory Profile: Delivers a smooth, non-greasy, and comfortable after-feel, significantly enhancing the user experience in topical applications.
Diverse Industry Applications
Extract Warehouse’s Carbomer 940 Powder is highly versatile, catering to multiple formulation sectors:
- Cosmetics & Personal Care: The industry standard for creams, lotions, sunscreens, hair gels, and clear serums. It imparts a luxurious texture and excellent spreadability.
- Topical Pharmaceuticals & Dermatology: Widely utilized in medicated gels, skin creams, and ophthalmic solutions due to its biocompatibility, simple processing, and excellent stability.
- Health Care & Nutritional Products: Utilized as a functional excipient, suspending agent, or texture modifier in specific health care products, oral care formulations (such as toothpastes), and liquid nutritional supplements.
Formulation Compatibility and Processing Guidelines
To achieve optimal performance with Carbomer 940 Powder, formulators should follow precise hydration and neutralization protocols:
- Dispersion: The powder must be dispersed uniformly in water. Using high-shear mixing or sifting techniques is recommended to prevent the formation of lumps ("fish-eyes").
- Hydration: Allow sufficient time for the polymer to fully hydrate and swell. The viscosity will initially remain low due to the acidic pH.
- Neutralization: Gradually add a neutralizing agent (e.g., Triethanolamine, Sodium Hydroxide, or Tromethamine) to achieve a target pH range of 6.0 to 7.0 (optimal at 6.5 - 7.0). This triggers maximum swelling and viscosity build-up.
- Compatibility: It is highly compatible with non-ionic surfactants and most active ingredients. However, high concentrations of electrolytes or cationic polymers may reduce the final viscosity.
