Core Properties

1. Ultra - efficient thickening and gelling: It can significantly boost viscosity at extremely low usage levels, usually 0.2% - 0.5%. After neutralization, it forms a smooth and transparent gel that gives products a premium texture without any gritty feel.
2. Excellent suspension and stabilization: It can effectively keep insoluble particles such as pigments, mineral powders, and active ingredient microcapsules in suspension, and stabilize oil - in - water (O/W) emulsions, preventing sedimentation, stratification, or creaming during the storage and use of products.
3. Superior clarity and sensory performance: The neutralized gel is highly transparent, which can enhance the visual appeal of gel - type products. Additionally, it contributes to a silky and non - sticky sensation on the skin and hair, improving the overall user experience of the products.

4. Good compatibility and processability: It works harmoniously with most anionic, non - ionic, and amphoteric surfactants, as well as common additives including humectants, preservatives, and plant extracts. It is easy to disperse and dissolve, and the neutralization process is simple, facilitating large - scale production.

   
   

Key Applications

1. Cosmetics and Personal Care

• Hair styling gels: It serves as the main gelling and thickening agent, providing long - lasting hold, high clarity, and a non - sticky finish. It can also stably suspend glitter or color particles, with a recommended dosage of 0.3% - 0.8%.
• Facial moisturizing gels and serums: It forms a transparent gel matrix to suspend active ingredients like vitamin C and hyaluronic acid, and enhances the skin - feel while offering excellent moisture - locking performance, with a recommended dosage of 0.2% - 0.5%.
• Skin lotions and creams: It stabilizes O/W emulsions, avoids oil - water separation, and improves the product's spreadability and skin - compatibility, making it suitable for formulations designed for sensitive skin, with a recommended dosage of 0.1% - 0.3%.
• Shampoos and body washes: It suspends conditioning particles such as silicone oil microspheres and plant extracts, thickens surfactant - based systems, and enhances foam stability and product texture, with a recommended dosage of 0.2% - 0.4%.

2. Pharmaceutical Products

• Topical gels and ointments: It acts as a gel matrix for drugs like anti - inflammatory and antipruritic agents, ensuring even drug distribution and good skin adhesion to achieve sustained - release effects.
• Oral care products: It thickens toothpaste and mouthwash formulations, suspends abrasive particles and active ingredients such as fluoride, and improves the consistency and usability of the products.

3. Household and Other Applications

• Hand sanitizers and disinfectant gels: It forms a transparent and fast - drying gel base, suspends disinfectant components, and guarantees stable efficacy and a comfortable feel after use.

• Household cleaning gels: It thickens and stabilizes cleaning formulas, suspends abrasive particles, and prevents splashing during use, making it suitable for cleaners used on glass, in kitchens, and bathrooms.

  
  

Processing and Storage Guidelines

1. Processing tips: To avoid agglomeration, first disperse Carbomer 940 in water or a water - glycol mixture under low - shear stirring. Then, add the neutralizer slowly while continuing to stir until a uniform gel is formed. Refrain from adding high - concentration electrolytes before neutralization as they may hinder the swelling of the polymer.
2. Storage conditions: Store it in a sealed container in a cool, dry, and well - ventilated area, away from direct sunlight, moisture, and incompatible substances like strong oxidants. With proper storage, its shelf life is generally 24 months.
3. Safety notes: It is non - hazardous and non - irritating when used normally. During operation, avoid inhaling dust to prevent respiratory discomfort. If it gets into the eyes, rinse them thoroughly with plenty of water.
