Carbomer 980: Intelligent Rheological Control Master, Multiphase System Stability Tool, Enabling Product Innovation Vitality
Product Introduction:
- Carbomer 980 is a crosslinked polyacrylic resin, chemically known as crosslinked polyacrylic acid.
- The appearance is white loose powder, which is an important polymer. With good rheological properties and a variety of functions, it is widely used in personal care products, pharmaceuticals and other fields of rheological modification thickener.
- It is specially designed for thickening of surfactant systems. This "easily dispersed" cross-linked polyacrylate copolymer is processed in a cosolvent system with toxicological advantages, resulting in excellent thickening efficiency, suspension capacity, long viscous flow properties, and crystal transparency in the gel system. Because of the low viscosity of the dispersion before neutralization, it is designed to reduce the effect of caking on the dispersion in water and to make it easier to pump and handle.
The role and efficacy of Carbomer:
1.Reduce the viscosity
- Carbomer have loose, and it is a very strong acidic substances, water imbibition common when making suspected glue or protect skin to taste, to be able to add the right amount of Korea's big aunt, it can reduce the material thick, smooth and can keep their characteristics, in today's industrial production production, carbomer is the key to making skincare and doubt rubber raw materials.
2.Anti-inflammatory and antibacterial
- Carbomer is also a pure natural medicinal value ingredient, which can reduce inflammation and eliminate bacteria. Nowadays, carbomer eye drops sold in the pharmaceutical market are made with it as the key raw material for treatment. It has excellent clearing effect on human eye inflammation, and can make patients' pain and redness of eyes disappear quickly.
The quality of the product:
1. Physical properties
- Soluble in water, ethanol and glycerin and other solvents, with a certain hydrophilic properties, the molecular structure of the acid group, is weakly acidic, with short rheology, can provide high viscosity under low dosage, the formation of a clear and transparent gel.
2. Chemical properties
- Good stability, with excellent suspension stability and temperature stability, not easily affected by external factors, in acidic or alkaline environment can maintain chemical stability, relatively friendly to the environment.
Common application cases of the product:
1. Cosmetics
- As a rheological modifier in skin care lotions, creams and transparent gels, it provides thickening and suspension properties, making the product more stable and delicate.
- In hair styling gels, shampoos, and body washes, it can increase the consistency of the product, better fit the skin or hair, help lock in moisture, make nutrients more easily absorbed, and stabilize the many active ingredients in the formula.
2. The field of medicine
- Used as pharmaceutical excipients, such as making water alcohol gel, moisturizing gel. To provide a stable release environment for medicine, in transdermal preparations, to help the penetration and absorption of medicine, but also by adjusting its chemical structure and molecular weight to control the drug release rate and duration, the medicine wrapped in the polymer, and through progressive dissolution, diffusion or hydrolysis to release medicine, improve drug efficacy and reduce toxic side effects.
3. Food industry
- As a food additive, it provides a stable thickening effect.
4. The petroleum industry
- As a thickening agent and stabilizer of drilling fluid, it can effectively improve the viscosity and stability of drilling fluid, prevent wall collapse, and ensure the smooth progress of drilling operations.
Advice:
- Recommended usage is 0.2-1.5wt %, while stirring the polymer evenly scattered in the medium, but to avoid agglomeration, fully stirred to disperse, and to pH 7.0~10 polymer has ideal thickening performance, after neutralization should avoid high-speed shear or stirring to reduce viscosity loss.
Suggested applications:
- Transparent gel, water alcohol gel, surfactant system (special shampoos, cleaning products, etc), a system with high electrolyte content (Aloe vera gel),etc.
Using Tips:
- After carbomer completely dissolves water, it needs to add alkaline substances to neutralize to achieve good results, such as triethanolamine, sodium hydroxide and so on.
