Product Description
Sodium Carbomer
Sodium carbomer is a versatile rheology modifier widely used in the cosmetic industry. It is a synthetic polymer that functions as a thickening agent, enabling the formulation of various cosmetic products with desired textures.
Key Features:
- Fast Dispersion: Sodium carbomer readily disperses in water, simplifying the formulation process.
- Viscosity Control: It effectively increases the viscosity of aqueous solutions, transforming them into gels, creams, and lotions. This allows for customized product textures, from lightweight serums to rich, creamy moisturizers.
- pH Sensitivity: The viscosity of sodium carbomer solutions is significantly influenced by pH. Optimal viscosity is typically achieved within a pH range of 4.0 to 7.0.
Cosmetic Applications:
- Skincare:
- Moisturizers and Creams: Sodium carbomer helps create stable emulsions, ensuring even distribution of active ingredients and providing a smooth, luxurious feel.
- Lotions and Serums: It imparts a silky texture and enhances the spreadability of lightweight formulations.
- Gels: It forms clear, transparent gels that are easily absorbed by the skin.
- Sunscreens: It improves the stability and spreadability of sunscreen formulations.
- Hair Care:
- Shampoos and Conditioners: Sodium carbomer thickens these products, enhancing their cleansing and conditioning properties.
- Hair Styling Gels: It forms strong holds while maintaining a natural look and feel.
- Hair Masks: It creates rich, creamy textures that deeply nourish and condition hair.
- Color Cosmetics:
- Foundations and Concealers: It provides a smooth, even application and helps to control the flow of the product.
- Lipsticks and Lip Glosses: It adds texture and improves the adherence of the product to the lips.
- Other Applications:
- Facial Cleansers: It creates rich lather and helps to remove makeup effectively.
- Eye Creams: It provides a smooth, non-greasy texture that is gentle on the delicate eye area.
Typical Usage Levels:
Sodium carbomer is typically used at concentrations of 0.5% to 10.0%, depending on the desired viscosity and the specific formulation.
Solubility:
Sodium carbomer is typically soluble in water at concentrations of 0.2% to 0.5%.
Cosmetic Recipe Example:
Simple Hydrating Gel
-
Ingredients:
- Sodium carbomer: 0.5%
- Triethanolamine (TEA): to adjust pH to 6.0-6.5
- Aloe Vera Gel: 99.5%
- Essential Oil (optional): a few drops (e.g., lavender, rose)
-
Instructions:
- Slowly add sodium carbomer to aloe vera gel while stirring continuously to avoid clumping.
- Gradually add TEA dropwise, stirring constantly, until the desired pH is reached.
- Continue stirring until a smooth, transparent gel forms.
- Add essential oil (if desired) and mix well.
Recommendations for Use:
- Neutralize with a base: Sodium carbomer is anionic and requires neutralization with a base, such as triethanolamine (TEA), to achieve optimal viscosity.
- Avoid overheating: Excessive heat can degrade the polymer, affecting its thickening properties.
- Proper dispersion: Ensure thorough and even dispersion of sodium carbomer in the aqueous phase to avoid lumps and ensure consistent viscosity.
- Storage: Store in a cool, dry place away from direct sunlight.
