| Message: | Carbomer 980 is a commonly used carbomer series material. Carbomer is a high molecular polymer of acrylic acid-bonded allyl sucrose or pentaerythritol allyl ether, usually a loose white slightly acidic powder, which can be used in low dosage Produces an efficient thickening effect, thereby preparing emulsions, creams, gels and transdermal preparations with a wide viscosity range and different rheological properties.
Different carbomers have slightly different properties. Different models represent different viscosities and are known as short rheology or long rheology. For example, carbomer 940 has short rheological properties and reaches 63000MPA.S at 0.5% viscosity, suitable for viscosity. High product, Carbo 941 has long rheological properties, at a viscosity of 0.5% up to 7500MPA.S suitable for low viscosity products, Carbomer's corresponding models have ion resistance and ion resistance performance. Carbomer 980 has good thickening, high transparency, high viscosity, and strong suspending ability. Carbomer 980 is widely used in daily chemical products, such as skin care lotions, creams, transparent gel products, transparent skin care gels, hair styling gels, shampoos, shower gels, and leave-on disinfection gels.
Dissolution method in water or homogenizer:
First add carbomer to dissolve in deionized water according to the actual production requirements without stirring. After carbomer naturally absorbs water, the white powder on the surface and the white agglomerate in the solution can not be seen. Stir evenly. Then add the neutralizer (Carbo: Neutralizer = 1: 1, Carbo: 5% Neutralizer solution = 1.4.5) Adjust the PH value to about 7 to achieve a thickened state, use a round tool or disperser , Stir evenly at low speed. Adding a homogenizer, adding according to the actual production ratio, no white mass can be seen, adding neutralizer to form a gel, and then using a vacuum emulsification pot to evacuate the air from the gel.
