What is carbomer explain with example?
Carbomer is the trade name for polyacrylic acid. Companies use it extensively in formulations across multiple industries, including cosmetics, pharmaceuticals, and personal care. Carbomers are synthetic, crosslinked polymers of acrylic acid with a high molecular weight. Dried carbomers are lightweight, white powders.
What is the difference between carbomer 940 and 980?
The key difference between carbomer 940 and 980 is that carbomer 940 is important as a rheological modifier, while carbomer 980 is important as a thickening agent. Carbomer is the market name of polyacrylate polymer. There are different types of carbomer materials based on their composition and applications.
What is Carbomer made of?
What is Carbomer? Carbomer is a term used for a series of polymers primarily made from acrylic acid. Carbomers are white, fluffy powders but are frequently used as gels in cosmetics and personal care products.
What is the pH of Carbomer?
2.7 – 3.3
Carbomer 940 is a polyvinyl carboxy polymer used as a viscosity enhancer, gelling agent, or suspension agent….SPECIFICATIONS.

Is Carbomer a compound?
Carbomer is a high molecular weight polymer compound used commonly in the cosmetic industry. These compounds can absorb large amounts of water, increasing in volume up to 1,000 times to form gels and thick solutions that are stable and resistant to spoilage. When not in solution, they carbomers exist as a white powder.
How do you make a carbomer?
The preparation method of the carbomer comprises the steps as follows: the acrylic acid, the initiating agent, the cross-linking agent, the stabilizing agent and the mixed solvent are mixed uniformly and proportionally; an obtained mixture is added into a reaction still and stirred, after nitrogen feeding and bubbling.
What is carbomer in chemistry?
Carbomers. Carbomers are acrylic acid polymers that are used for a variety of purposes. They are used in pharmaceutical processes as suspending agents, gel bases, emulsifiers, and binding agents. They are also used as artificial tears.
What are the properties of Carbomer?
Carbomer is a water and alcohol soluble polymer. It is a mildly acidic and forms a loose network when partially neutralized to pH 5-8. Carbomer requires a long time to swell properly for use. It is best to make a pre-gel before beginning the batch at hand.
