Carbopol applications

The determined macro- and microelement stmcture of mumio specifies onto the expediency of the application of this biologically active substance as a cosmetic raw material in the cosmetic compositions, which do not contain carbopol. The developed procedure for calcium and sodium ions determination in pectin-containing vegetative extracts is express and it is recommended for application at elaboration of cosmetic production compositions on the carbopol base. 

Carbopol resins also have been used in controlled-release dosage forms. Especially, the resins Noven AA-1 USP and Carbopol 934P NF are being extensively developed in bioadhesive drug delivery systems for topical, bucal or nasal, ocular, and rectal applications (e.g., Fentanyl ). Noven CA-1 USP and CA-2 USP are used as oral laxative and antidiarrheal products in swallowable and chewable tablets. 

Skelland and Kanel [513] established, that the relationship [512] given by them in Table 6.1 was also fully applicable, if a Newtonian liquid (diisobutyl ketone) was stirred into a pseudoplastic liquid (aqueous solutions of Carbopol 934, a stongly acidic acrylic acid polymer), if its apparent density, which obeys the power law of Metzner and Otto, was appropriately taken into consideration. 

There are applications where the viscosity of the dispersion must be increased to maintain uniform wet thickness in the process. Addition of water-soluble thickeners such as acrylic polymers is one way of increasing the viscosity of the dispersion. For example, the addition of 1% of Carbopol 934 (supplied by B. F. Goodrich Co.) can increase the viscosity of a dispersion containing 60% solids by 30 times to about 6 poise.Other examples of thickeners include Acrysol ASE acrylic polymers, by Rohm Haas, and Natrosol hydroxyethyl cellulose polymers, by Hercules Corporation. 

Carbopol resins are used in this formula to thicken the gluconic acid to enable improved application efficacy. The polymer will also impart vertical cling to enable applications on vertical or angled surfaces. 

Regulatory Status Carbopol 1382 and Pemulen TR-1 and TR-2 are manufactured without benzene. Carbopol 1342 and Pemulen TR-1 and TR-2 are approved by Japanese MHW Special Comments If higher-viscosity emulsions are required, Carbopol resins may be used in combinations with Pemulen TR-1. Pemulen TR-2 is effective where the mode of emulsion applications is via spray mechanism Form Supplied Powder Supplier BF Goodrich...
