Carbomer 940 Powder Usage and Synthesis.

Carbomer 940 Powder is commonly used for film coating, solid dispersion, sustained-release pellets, and sustained-release skeleton tablets. In addition, Carbomer Powder has better performance as medicinal excipients and has broad development space.

Carbomer 940 Raw Materials are used as corrosion and scale inhibitor, water quality stabilizer, quenching agent, thickening agent, etc. Carbopol 940 Powder,also called Carbomer or Carboxypoly-methylene is a generic name for synthetic high molecular weight  polymers of acrylic acid used as thickening, dispersing,  suspending and emulsifying agents in pharmaceuticals and cosmetics. 

They may be homopolymers of acrylic acid,  crosslinked with an allyl ether pentaerythritol, allyl ether of sucrose or allyl ether of propylene.

Application/Function of Carbomer 940 Powder.

• 1. For pharmaceutical preparations:

Because acrylic resin has the advantages of safety, stability, inertness and non-irritation, it is a polymer material widely used in pharmaceutical preparations. Acrylic resins can be divided into two categories: methacrylic acid copolymers and methacrylate copolymers, which have various characteristics such as solubility in gastric and intestinal fluids or insolubility in water due to different copolymer components and ratios. Therefore, they are often used in film coating, solid dispersions, slow-release micro-pills, slow-release skeletal tablets and other pharmaceutical applications.

In addition, acrylic resin as a pharmaceutical excipient with more excellent performance, has a broad space for development.

• 2. For coatings:

Acrylic resin has light color, good transparency, excellent light and color retention; high temperature does not decompose and does not change color, has good resistance to acid and alkali, salt and grease detergents and other chemicals staining and corrosion performance, as well as excellent construction performance. Especially, it can be widely modified with various chemical monomers and new materials, and endowed with various special properties to prepare new varieties of acrylic resin coatings.

Preparation of Carbomer 940 Powder.

1. Carbomers are found in the market as white and fluffy powders. They have the ability to absorb, retain water and swell to many times their original volume. Carbomers codes (910, 934, 940, 941 and 934P) are an indication of molecular weight and the specific components of the polymer .
2. Carbopol, also called Carbomer or Carboxypoly-methylene is a generic name for synthetic high molecular weight polymers of acrylic acid used as thickening, dispersing, suspending and emulsifying agents in pharmaceuticals and cosmetics.
3. Carbopol U10 is a cross-linked polyacrylate polymer. It offers excellent stability at high viscosity and produces thick formulations for cosmetics.Carbopol 940 Powder is used for topical formulations and suitable for preparation of gels, creams and coupling agent. Carbomer and cross- linked acrylic resin as well as series products of these cross-linked polyacrylic acid are widely used at present and are often used in topical lotion, cream and gel. In a neutral environment, Carbomer system is an excellent gel matrix with crystal appearance and nicesense of touch, so Carbomer is suitable for preparation of cream or gel. 

1. Carbomer 940 Powder is used as a scale inhibitor and dispersant in industrial water treatment. Good compatibility. Also used as a pretreatment for drinking water. Used to separate red mud in alumina preparation. Used in chlor-alkali plants to refine brine.
2. Carbomer 940 Powder is used in the preparation of leather and some high-grade goods finishing agent, the production of acrylic resin paint, etc.
3. Carbomer 940 Powder is used to fix chromium salt, assist in tanning, reduce chromium pollution, etc. It is used to improve the processing performance of polyvinyl chloride.
4. Carbomer 940 Powder is used as corrosion and scale inhibitor, water stabilizer, quenching agent, thickening agent, etc.
5. Carbomer 940 Powder is used as a filling agent for leather finishing, textile slurry and water stabilizer.
6. Carbomer 940 Powder is used in the manufacture of acrylic resin lacquers.
7. Carbomer 940 Powder can be used as a film-forming agent and binder in leather finishing agent, and also used in the manufacture of polyacrylic resin emulsion lacquer, etc. It is widely used in the decoration of light leather such as face leather, garment leather, glove leather, etc. It can enhance the bending resistance, extensibility, light resistance, aging resistance, cold resistance and heat resistance of leather, and is the main finishing film-forming agent for finishing grain leather with pigment paste.
8. Carbomer 940 Powder is mostly used in the manufacture of cosmetics, as an ointment to promote the absorption of gray yellow mold, and can be used for drug control release.
