Carbomer 940 is a type of synthetic polymer, commonly used in the cosmetic, pharmaceutical, and personal care industries. It is primarily used as a thickening agent and gelling agent due to its ability to form gels when neutralized. Here are some of its key uses:
1.Cosmetic Formulations:
- Skin Care Products: Carbomer 940 is frequently used in creams, lotions, gels, and serums to increase viscosity and create a smooth texture.
- Hair Gels: It helps to improve the texture and stability of hair styling products.
- Facial Cleansers: It thickens gel-based cleansers and contributes to the product’s smooth, gel-like consistency.
2.Pharmaceutical Products:
- Topical Gels: Used in medicated gels for topical application (e.g., anti-inflammatory gels, pain relief gels).
- Controlled Release: It is used in oral drug formulations for controlled-release tablets or capsules.
3.Personal Care:
- Shampoos and Conditioners: Helps thicken the product and maintain a consistent texture.
- Antiperspirants: Used to thicken aerosol and roll-on formulations.
4.Industrial and Household Products:
- Adhesives: Carbomer is sometimes used in adhesives and pastes for its thickening and gelling properties.
- Cleaning Products: In gel-based household cleaners.
How it works:
- Carbomer 940 is a crosslinked polyacrylic acid polymer. It is typically neutralized with an alkali (like sodium hydroxide or triethanolamine) to form a gel. This neutralization increases the viscosity of the product, giving it a thicker, more stable consistency.
Properties:
- Viscosity Building: Highly effective in increasing the viscosity of formulations without affecting the product’s clarity.
- Stability: Enhances the stability of emulsions and suspensions.
- Non-irritating: Considered gentle and non-irritating, which makes it suitable for sensitive skin products.
Carbomer 940 is a versatile ingredient that can be used across a wide range of product types, providing texture, stability, and performance.
