Cas 9003-01-4 Polyacrylic Acid Carbomer 940 Powder For Cosmetic Gel Matrix Application

Carbomer 940, or carbomer 940, is an easy-to-use water-soluble polymer that can be used as an emulsifier, stabilizer, suspending agent, thickener and gelling agent. Pom 940 is widely used due to its versatility and safety.

In many application scenarios, Carbomer 940 is the most widely used as a thickener. This is because the chemical structure of its polypropylene polymer makes it a very effective thickening agent. Carbomer 940 can produce high-efficiency thickening effects at very low doses, and is especially suitable for making transparent gels. With hydroalcoholic gel, it can produce a clear and transparent gel with very short rheology. It can be used to prepare various gels and creams when mixed with water or alcohol. It is suitable for the manufacture of various cosmetics, such as: moisturizing cream, lotion, sunscreen Cream, hair conditioner, etc.

The characteristics and advantages of Carbomer 940 for thickening:
Short rheology, high suspension ability, high viscosity, high definition. Popular applications: hair conditioner gels, hydroalcoholic gels, moisturizing gels, shower gels, facial creams, etc. (The typical dosage of Carbomer 940 is 0.1%-1.5%, depending on the required viscosity/thickness)

4 precautions for using carbomer, 5t supply from stock, white powder, used for daily chemicals

Carbomer is widely used in the coating industry, textile industry, pharmaceutical industry, construction industry, detergent and cosmetics industry. Because of its simple process and thickening and suspending effects, it is deeply loved by these industries. Although Carbomer is good, do you know what to pay attention to when using it? Let's take a look down.

1. Which configuration of Carbomer can't be used together
Soluble salt or VC and strong acid solutions will thin the carbomer and reduce its viscosity, but hyaluronic acid can be added in small amounts. Carbomer is incompatible with phenol, cationic polymers, and high-concentration electrolytes, so it should not be used together with carbomer.

2. The transparency of carbomer gel
In the production process of some gels, ethanol is added to increase the corrosion resistance and permeability. However, when the concentration of ethanol is too high, the resulting gel will have a light milky white color and reduce the transparency of the gel. For example, if the concentration of ethanol is greater than or equal to about 75%, the transparency of disinfection and disposable gel is greatly reduced.

3. Carbomer packaging
Due to the large daily consumption of carbomer in some industries, many purchasers may stock up some goods when buying carbomer, but carbomer has a strong hygroscopicity, so when storing it, Store in a dry place, must pay attention to seal, do not expose to the air, to avoid moisture absorption and agglomeration affect the thickening.

4. The choice of carbomer manufacturers
In addition to high light transmittance, good suspension, strong stability, and high viscosity, you must also pay attention to whether the after-sales is worry-free and the service is guaranteed. Choosing a manufacturer with good after-sales service is the best way to avoid thundering during use.

1. Carbomer's levitation

Carbomer can make the liquid system have a special yield value and rheology, and only a very low concentration can make some insoluble additives (particles, oil droplets, etc.) permanent suspension. It is precisely because of this strong suspending ability that carbomer is widely used to stabilize traditional emulsions and creams, oil droplets and water-insoluble matter in suspension solutions. Other thickeners are often not available. Very high thickening suspension power and yield value.

2. Rheology of Carbomer

Most carbomer gels have almost no rheology. When the carbomer gel is stressed, its viscosity will immediately decrease, but when the stress disappears, its viscosity will be restored immediately.

3. Carbomer sensitivity

Mechanical shearing-After carbomer is neutralized, long-term stirring or high-shear stirring will cause viscosity loss

The presence of ions-electrolytes will reduce the thickening efficiency

·Ultraviolet rays--Long-term ultraviolet radiation will reduce the viscosity of the carbomer gel when pH>/=10, when exposed to ultraviolet rays

4. Carbomer's insensitivity

·Temperature change--Carbomer gel is not affected by temperature

·Microorganisms-Carbomer does not support the growth of bacteria and mold, and the growth of bacteria and mold does not affect the gel properties. The conventional dosage is 0.2-0.4%, which can replace 3-7% of conventional emulsifiers. Carbomer polymer has almost no surfactant properties, so adding 0.1-0.5% surfactant with low HLB value can adjust the oil phase particles to be smaller to prepare white and delicate cream products.

5. Carbomer polymer emulsifier is better than general emulsifier

·Effective at a very low concentration-0.1-0.5%, replacing the traditional surfactant dosage of 3-7%

·Not restricted by HLB value and PlT

·Can emulsify any liquid oil at room temperature

·If the wax is melted during the manufacturing process, the wax can be emulsified

·Give full play to the wetting, dispersing, adhesion and other functions of surfactants to make stable emulsions

·It will not re-emulsify when re-wetting, and it is easy to prepare waterproof emulsion without film-forming agent

·The high oil phase can be dissolved in water to form (o/w) emulsion

Can be prepared: moisturizing creams, lotions, cleansing products, sunscreen products, non-alcoholic perfumes, fragrance hair conditioners (enhanced gloss, easy to comb), hand sanitizers, low-consistency sprayable emulsions and transparent microemulsions, etc. There are many methods to reduce the difficulty of carbomer in application. One method is to add carbomer to the oil phase system to slow down its swelling speed, the so-called indirect method, but it depends on the formulation. Carbomer is not very sensitive to changes in the addition process.
