Hydroalcoholic gels basically contain four major ingredients: alcohol, water, rheology modifier and neutralizer.          The effectiveness of the sanitizer using alcohol depends on the amount and type of alcohol. The FDA proposed monograph considers the effective concentrations as follows: • Ethanol at 60-95 v/v% • Isopropanol at 70-91.3 v/v%. Carbomer Selection Although ...

Carbomer product are cross-linked polyacrylate polymers, including polyacrylic acid homopolymer and acrylate copolymer. They are polymerized by method of solvent polymerization -precipitation polymerization. NM-Carbomer are defined as short flow type and long flow type by their viscosity. For example, NM-Carbomer 940, 980, 676, 996 with 0.5% solution viscosity ~55,000maps, are short flow property....

As a leading professional manufacturer of carbomers,  Anhui Newman fine chemical launched new type Carbomer --compendial grade such as NM-carbomer 934P, 980G, 940G/940NF 941G/41NF,981G, especially applied in pharmaceutical field as excipient.

Carbomer’s appearance are White fluffy powder with Slightly acetic odor, being water-soluble polymer. Their usage is 0.2%~1.5%. Because their chemical structure contains a large number of carboxyl groups, the aqueous solution should pay special attention to use after alkali neutralization to reduce the skin and mucous membrane irritation. Carbomer neutralizing agents include sodium hydroxide, pota...

Newman have attend PCHI in Shanghai 2018, hundreds of visitors have been to our booth, our product is welcome by the customer all over the world. Newman is a leading manufacture of carbomer in China, our quality leading domestix leverl and reaching the international standard.

1.Neutralizers Type Normally, Carbomomer is neutralized into salt to make the crimped molecules thicken due to the repulsion of the repulsion. Sodium hydroxide and triethanolamine are commonly used neutralizers. This is why Carbomer is sensitive to ions. 2. hydrogen Type Carbomer molecules can be thickened by the combination of one or more hydroxyl groups as a carboxyl group to form a hydrogen bon...

Carbomer is a thickener that helps to control the viscosity and fluidity of cosmetics. It also helps insoluble solids disperse and suspend in liquids, preventing the separation of water and oil from the solution. They also absorb and retain water, which expands by 1000 times in water. Such ingredients are commonly used in gel formulations, where when mixed with water, they form a sticky glue. On t...

Carbomer 20/21/2020 are a hydrophobically modified cross-linked acrylate copolymer,provide high viscosity with short flow properties. Their self-wets and disperses quickly in minutes, which remarkably meets formulators’ ease-use need. They deliver excellent thickening efficiency at a wide pH range which makes them a good choice for wide applications. They are  ideally suited for use in formul...
