Function
Here are some of the key features and uses of Carbopol 990:
1.Thickener: Carbopol 990 can significantly increase the viscosity of aqueous solutions and is commonly used in lotions, gels and creams.
2.Suspending agent: It can help suspend insoluble ingredients and make the product more uniform and stable.
3.Stabilizer: Carbomer 990 can stabilize the emulsion and prevent oil-water separation.
4.pH adjustment: Carbomer 990 shows different viscosity characteristics under different pH values, and usually works best under neutral or weakly alkaline conditions.
5.
How to use:
- Dissolution: Carbomer 990 usually needs to be dissolved in water and the pH adjusted with a neutralizing agent (such as triethanolamine) to achieve the desired viscosity.
- Concentration: The concentration used is typically between 0.1% and 1%, depending on the desired viscosity and formulation of the product.
Note:
- pH Sensitivity: Carbomer 990 is very sensitive to pH and must be used within the appropriate pH range for best results.
- Compatibility: When using it in formulas, you need to pay attention to its compatibility with other ingredients to avoid adverse reactions.
Overall, Carbopol 990 is a very effective thickening and stabilizing agent that is widely used in a variety of personal care and pharmaceutical products.
Application
Carbomer 990 has a wide range of applications in several fields, mainly in cosmetics, personal care products, and pharmaceuticals. Here are some specific application scenarios:
1.Cosmetics and personal care products
Creams and lotions: Carbomer 990 acts as a thickener and stabilizer to improve the texture and stability of the product, making it easier to apply and absorb.
Gel: Among clear gels, Carbomer 990 provides high transparency and good touch, and is commonly used in moisturizing gels, eye creams and post-sun repair gels.
Shampoo and body wash: It can increase the viscosity of the product, making it easier to control and use, while also stabilizing the active ingredients in the formula.
Sunscreen: Carbomer 990 helps disperse and stabilize the sunscreen, improving the product's effectiveness and experience.
2. Medical field
Pharmaceutical gel: Carbomer 990 can provide good adhesion and extensibility to help the drug to be better absorbed in the topical application gel.
Eye drops: As a thickening agent, Carbomer 990 can increase the viscosity of eye drops and prolong the residence time of the drug on the surface of the eye, thereby improving the efficacy.
Oral suspension: Carbomer 990 can help to suspend insoluble drug components, making the drug more homogeneous and stable.
