What is Carbopol 980 NF?
Carbopol® 980 NF polymer is a highly efficient thickener and it is ideal for formulating clear aqueous and hydroalcoholic gels. The polymer has short flow rheology similar to mayonnaise.
Is Carbomer 940 toxic?
The Carbomer polymers are used in cosmetics and emulsifying agents at concentrations up to 50%. Acute oral animal studies showed that Carbomers-910, -934, -934P, -940, and -941 have low toxicities when ingested.
What is Carbomer and is it safe?
“Carbomer has been assessed as safe to use in cosmetic products,” he assures. “It has been shown that carbomers can be used by everyone and have no adverse effect.” Known to be safe for all skin types, carbomers are fluffy white powders that allow other ingredients in your products to work together to get the job done.
Why is Carbomer in toothpaste?
Carbomers are thickening agents that help control the viscosity and flow of cosmetic products. They also help distribute and suspend insoluble solids into liquid, and prevent the oil and liquid parts of a solution from separating.
What is Carbomer 974P?
Carbomer 974P is a polyvinyl carboxy polymer used as a viscosity enhancer, gelling agent, or suspension agent. Carbomer 974P is cross linked with ethers of , and is used primarily in systems where sparkling clarity or a sharp viscosity response is required.
How many types of Carbomer are there?
Product Overview and Recommendations
| Carbopol Polymer | Polymerization Solvent | Carbomer Product Type |
|---|---|---|
| 934P NF | Benzene | Homopolymer |
| 940 NF | Benzene | Homopolymer |
| 941 NF | Benzene | Homopolymer |
| 1342 NF | Benzene | Copolymer |
How do Carbomers work?
Carbomers absorb water readily upon contact with water, become hydrated, and swell. In tablets, carbomers are employed as a binder and control the release of active medicament. It is suitable for both wet and dry granulation processes.
What is a carbomer copolymer?
» Carbomer Copolymer is a high molecular weight copolymer of acrylic acid and a long chain alkyl methacrylate cross-linked with allyl NF24 ethers of polyalcohols. NOTE— The heading of this monograph does not constitute the official title for a Carbomer Copolymer manufactured with the use of benzene.
Are carbomers toxic to humans?
The toxicity of carbomers has been summarized by the Cosmetic Ingredient Review Expert Panel in their assessment of the safety of the carbomers for cosmetic ingredients. This assessment and subsequent toxicology testing have demonstrated a low toxicity and irritation potential.
Is Lubrizol FDA approved for the treatment of carbopol 971p NF polymer?
Lubrizol has supporting data for dermal, ocular, and oral toxicology testing for Carbopol 971P NF polymer. Bulletin 2 provides a summary of all toxicology studies for Lubrizol’s pharmaceutical grade polymers. Additionally, Lubrizol has filed a Type V DMF with FDA. A letter of authorization (LOA) can be issued for FDA drug applications.
What is the release rate of carbopol?
Oral solid dose – immediate release: 0.5-3 wt% Powder and granular grade Carbopol polymers can be combined in a formulation to achieve desired release profiles. The release rates can be modulated by incorporating powder grades polymers, such as 974P NF, and then blending with Carbopol 71G NF granular polymer.
