What is Carbomer Resin?

Carbomer resin is a synthetic high molecular polymer with the molecular formula C5H10O2. From the perspective of chemical raw materials, it is a free radical copolymerization of acrylic acid and allyl ether in the presence of an initiator, and then through A type of acrylic resin made by cross-linking treatment with cross-linking agent. Its molecular structure contains repeated carboxylic acid groups (-COOH), which allows it to undergo a neutralization reaction when encountering alkaline substances, forming a highly swollen gel-like substance.

Carbopol resin is divided into multiple models according to the degree of polymerization and cross-linking, such as Carbopol 940, Carbopol 980, etc. Each model has different characteristics, such as viscosity, transparency, thixotropy, etc.

Carbomer Resin Property

Carbomer Resin Uses

Personal care and cosmetics industry:
Carbopol resin is often used as a rheology modifier, which can give products excellent gel properties. For example, it is used in the manufacture of cleansing products, skin creams, lotions, facial masks, sunscreens, etc. It can increase the consistency of products, improve the application feel, and Helps disperse and stabilize active ingredients in formulas.
In hair care products, carbomer resin is used to create hair styling gels and mousses that provide long-lasting hold and are easy to wash off.
In oral care products, carbomers are used in toothpastes and other oral care gels to improve the consistency and mouthfeel of the products.

Pharmaceutical field:
Carbomer resin is used to prepare external pharmaceutical preparations, such as medicinal gels, wound healing materials, and local analgesic patches, etc., because it can form a protective film on the skin surface, which helps to release drugs slowly and promote wound healing. and pain relief.
In ophthalmic drugs, carbomer can be used as the basic component of eye drops and eye ointments to help moisturize and lubricate, while also inhibiting the growth of microorganisms and used as an auxiliary treatment for dry eye syndrome and other eye diseases.

Home and Hygiene Products:
In household and personal hygiene products such as hand soap, shower gel, laundry detergent, etc., carbomer tree
It can provide the right consistency and foam stability, enhance the use feeling and keep the product uniform and stable.
In no-rinse disinfectant gel products, carbomer resin is used as the basic gel agent, which not only provides a suitable touch, but also helps the disinfectant ingredients stay on the skin surface for a longer time, thus improving the disinfection effect.

Other areas:
Carbomer resin is also used in the construction industry, such as as an additive in certain coatings and sealants, providing good viscoelasticity.
In industrial cleaners, it can increase the viscosity and stability of the solution, optimizing the cleaning effect and user experience.

Characteristics of Carbomer Resin

Structural features: Carbopol resin is a cross-linked polyacrylic acid or acrylate copolymer with a large number of carboxylic acid groups (-COOH) on its molecular chain, making it highly anionic. After being dispersed in water, the carboxylic acid groups will be ionized by reacting with alkaline substances (such as sodium hydroxide, potassium hydroxide) to form a highly swollen gel structure.

Rheological properties: Carbomer resin has excellent rheological properties and can significantly change the viscosity, thixotropy and yield stress of aqueous systems. Depending on the model and dosage, carbomer resin can be made into various product forms from light liquid to hard gel.

Thickening and suspending ability: As an efficient thickener and suspending agent, carbomer resin is widely used in cosmetics, pharmaceuticals and personal care products. It can effectively improve the consistency and stability of the product and ensure that the ingredients in the formula are evenly dispersed. Avoid precipitation and separation.

Biocompatibility and safety: Carbopol resin has good biocompatibility and safety and has been approved for use in cosmetics, food contact materials and pharmaceutical fields. In contact with skin, it does not generally cause irritation or allergic reactions.

pH sensitivity: Carbomer resin is sensitive to pH value. As the pH value increases, the degree of ionization of its carboxylic acid group increases, resulting in increased swelling of the resin, thereby changing the viscosity and gel properties of the system.

Processability and practicability: Carbomer resin is easy to disperse and dissolve, and can quickly form a stable gel system at low temperature or room temperature without affecting the transparency of the product. In addition, it has good compatibility and is compatible with other ingredients in most cosmetics and personal care products.

Wide range of applications: Carbomer resin is widely used in cosmetics (such as lotions, creams, masks, shampoos, shower gels, etc.), pharmaceuticals (such as topical gels, ointments, suppositories, etc.), food additives (such as emulsifiers) , stabilizers), industrial cleaners, coatings and adhesives and many other fields.
