Product Description

Product Description

Basic Information

 

• Definition: Carbomer resin is a kind of polymer obtained by the copolymerization reaction of acrylic acid with cross-linking agents such as allyl sucrose or allyl pentaerythritol ether.
• Chemical Name: It is usually called cross-linked polyacrylic acid polymer, and different models may have more specific chemical names.
• CAS Registry Number: There are multiple CAS registry numbers, such as 9003-01-4, 76050-42-5, etc. Different CAS registry numbers have differences in the accuracy of referring to specific substances.

Physical and Chemical Properties

 

• Appearance: Generally, it is a white, loose powder with a slightly acidic odor.
• Solubility: It is insoluble in common organic solvents such as water and ethanol, but it can rapidly swell in water to form a transparent or translucent gel-like substance.
• Viscosity Characteristics: It can generate a relatively high viscosity even at a low concentration. The viscosity of its aqueous solution changes with the pH value and ionic strength. Usually, the viscosity is the highest in the pH range of 6-11, and it has a good thickening effect.
• Rheological Properties: It has the characteristics of a pseudoplastic fluid, that is, as the shear force increases, the viscosity of the solution will decrease, and when the shear force disappears, the viscosity will recover.

Application Fields

 

• Cosmetics Field
  • Thickening Agent: It is used to adjust the consistency of cosmetics, so that products such as lotions, creams, and gels have a suitable texture and spreadability.
  • Emulsifying Stabilizer: It helps the uniform mixing of the oil phase and the water phase, improves the stability of the emulsion, and prevents the separation of the oil phase and the water phase.
  • Suspending Agent: It makes the insoluble components in cosmetics uniformly suspended in the system, such as titanium dioxide and zinc oxide in sunscreens.
• Pharmaceutical Field
  • Gel Matrix: It is a commonly used matrix for preparing topical gel agents. It has good biocompatibility and can make the drug uniformly dispersed in the gel, slowly release the drug, and prolong the action time of the drug.
  • Tablet Binder: It helps to bond the drug powder together to make tablets and improves the hardness and stability of the tablets.
  • Sustained-release Material: It can be used to prepare sustained-release preparations. By controlling the release rate of the drug in the body, a long-acting and stable therapeutic effect can be achieved.
• Other Fields
  • Industrial Coatings: As a thickening agent and rheological modifier, it improves the construction performance of coatings and prevents phenomena such as sagging and dripping during the construction of coatings.
  • Adhesives: It increases the viscosity and cohesion of adhesives and enhances the bonding strength and stability of adhesives.
  • Water Treatment: It is used to treat industrial wastewater and domestic sewage. Through the adsorption and coagulation effects, it removes suspended particles and organic pollutants in water.
