2023年4月2日 · The main difference between carbomer and Carbopol is that carbomer is a generic name used to refer to any polymer derived from acrylic acid, whereas Carbopol is a trademark name owned by the Lubrizol Corporation for a specific type of carbomer.
Carbopol was the first marketed carbomer and undergoes strict LLS Health testing requirements that ensure product quality and safety. In contrast, “carbomer” is a generic name that can be used to describe any high-molecular-weight polymer of acrylic acid crosslinked with allyl ethers of polyalcohols. Carbomer is also the pharmacopeial name ...
By using the emulsification solvent evaporation method, floating microspheres can also be prepared with different grades of Carbopol: Carbopol 934, Carbopol 910, Carbopol 940, and Carbopol 941....
2013年11月29日 · The original synthetic powdered alkali swellable Carbomer was trademarked as Carbopol (US patent 2798503) and commercialized in 1958 by BF Goodrich (now known as Lubrizol). Carbopol 940, 941, and 934 were breakthrough technologies that revolutionized how personal care products are formulated and created new types of products that were ...
Carbomer codes (910, 934, 940, 941, and 934P) are an indication of molecular weight and the specific components of the polymer. For many applications PAAs are used in form of alkali metal or ammonium salts, e.g. sodium polyacrylate.
Products within the Carbopol polymer family are chemically similar in that they are all high molecular weight, crosslinked polyacrylic acid polymers. However, these gel forming polymers differ by their chemical crosslinking and can be grouped into the following categories.
2021年4月28日 · Carbomer 940 NF and Carbomer 934P NF. Also referred to as Carbopol ® Gels are clear and colorless; Concentration range is 0.2–2.5%; The pH range is 6.5–11; Approximately 30% lower viscosity when using carbomer 934P compared to carbomer 940
Carbopol® Ultrez 10 polymer is a universal polymer in the Carbopol polymer family.
