Function
Thickener
Increases viscosity: Carbomer SF-1 can significantly increase the viscosity of formulations, giving products the desired consistency and texture.
Gel
Transparent gel formation: A transparent and stable gel can be formed after neutralization, suitable for various gel products.
Stabilizer
Stable emulsification system: It can stabilize the emulsification system, prevent oil and water separation, and maintain product consistency and stability.
Suspension Agent
Suspended Solid Particles: Able to suspend solid particles in the formula to prevent sedimentation and maintain product uniformity.
Adjust rheology
Control Flowability: Able to adjust the rheology of the product so that it has ideal fluidity and thixotropy.
Provides smooth texture
Improve skin feel: Provide a smooth, silky texture and enhance the product use experience.
Application Areas
Cosmetics Industry
--Skincare: Used in creams, lotions, serums and masks to provide ideal viscosity and texture.
Cleansing Products: Increase the viscosity and foam stability of facial cleansers and cleansing foams.
--Make-up: Used in liquid foundation, BB cream, eye shadow and blush to provide smooth texture and good adhesion.
Personal Care Products
--Hair Care: Used in hair gels, waxes, shampoos and conditioners to provide great hold and shine.
--Hand Care: Used in hand disinfectant gel and hand cream to provide a refreshing feeling of use and good moisturizing effect.
Pharmaceutical Industry
--Topical Drugs: Used in ointments, creams and gels to increase the viscosity and stability of the product and ensure uniform distribution and effective release of the drug.
--Ophthalmic Preparations: Used in eye drops and ophthalmic gels to provide appropriate viscosity and lubricity to enhance the retention time and efficacy of the drug.
Industrial Application
--Coatings and Paints: Used to thicken and stabilize paints and paints to enhance their adhesion and coverage.
--Adhesive: Provides appropriate viscosity and stability to enhance the adhesion and durability of the adhesive.
Usage Guide:
Neutralization
pH Adjustment: In order to achieve the desired thickening effect, Carbomer SF-1 needs to be neutralized with an alkali (such as triethanolamine or sodium hydroxide) to adjust the pH value to about 6-7.
Concentration
Use Concentration: Typically the use concentration is between 0.1% and 1.0%, depending on the desired viscosity and application.
