CARBOMER 940 CAS NO.9007-20-9
Carbomer 940 is a white loose powder. It has strong thickening properties, high transparency, high viscosity, strong suspension ability, short rheology and thixotropy, and low resistance to ionic shear force. Swelling and slightly acidic. Widely used in transparent gel, essence and cream products, especially suitable for high-transparency products.
Carbomer 940 Detailed Introduction
Carbomer is a cosmetic thickener that produces high-viscosity thick bodies in very small amounts. Before it is not configured, its appearance is actually a white loose powder. After the solution is configured, it will produce a transparent viscous colloid. It has a very high range of use in daily chemicals. Desheng's Carbomer 940 also went through rounds of testing, and finally showed to customers after all the indicators reached the standard.
Advantages of Carbomer 940:
Effective at a very low concentration of 0.1-0.5%, replacing the traditional surfactant dosage of 3-7%;
Not limited by HLB value and PIT;
It 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 obtain stable emulsions;
It will not re-emulsification when re-wetting, and it is easy to prepare waterproof emulsion without film-forming agent;
The high oil phase can be dissolved into water to form (o/w) emulsion;
Can be prepared: moisturizing creams, lotions, facial cleansers, sunscreen products, alcohol-free perfumes, fragrance hair conditioners (enhancing luster, easy to comb), hand washes, low-consistency sprayable emulsions and transparent microemulsions, etc.
Advantages of Desheng on Carbomer 940:
From the feel: Desheng Carbomer 940 is relatively light and loose, because its molecules are highly polymerized long chains, and the molecules are relatively loose;
In terms of transparency: as Desheng is not good at fighting prices, maintaining high-level product quality is what they value. A very important indicator of high-level products is transparency. Desheng produces and develops carbs. Mu 940 has high transparency and can meet the needs of most buyers;
From the packaging specifications: the packaging of Carbomer 940 is completely determined by the needs of the customer. The conventional packaging specification is 20kg per box. If the order quantity is relatively small, it is usually packaged in bags. If the customer has his own special requirements, you can also press Need to be packaged, these are not a big problem;
In terms of delivery speed: Desheng has a professional production base and adopts imported production equipment. The daily output can reach 3-5 tons, which can meet the needs of customers for large-scale orders. At present, the stock is sufficient, no matter what the customer wants. Desheng has the ability to deliver goods quickly, regardless of whether it is a ton-level or ton-level cargo. Desheng promises that the goods must be shipped on the same day for orders that are completed on the same day;
In terms of price: the larger the order quantity, the greater the profit margin. Since Desheng started the annual promotion, it has received strong support from customers. Many customers are referred by old customers. I believe that many customers are visiting After passing the price of many manufacturers, there will be such a choice;
From after-sales: We are equipped with 2 professional after-sales specialists, who will guide and follow-up visits based on the information provided by customers.
Application of Carbomer 940
Carbomer 940 has the functions of thickening, suspending, emulsifying and pseudo-thixotropy, regulating the release of water and active substances, etc. It is widely used in personal care and home care products, such as cosmetics and hand sanitizer gel;
In the field of medicine, such as suspending agent and adhesive in pharmaceuticals, coupling agent in commonly used color ultrasound, etc.;
In the industrial field, rheology modifiers in water-based coatings, negative electrode gelling agents in alkaline batteries, gelling agents in solid fuel glue, etc.;
Applied to the neutral ink system, it not only improves the viscosity and pseudoplasticity of the neutral ink, but also improves the biological stability of the neutral ink;
It has high adhesion and can be used in lithium-ion batteries, which can improve the cycle performance of the battery.
Carbomer 940 Instructions for Use:
pH value: the optimum pH value range of Carbomer 940 is 4-10, higher or lower than this range will cause the viscosity of the system to change;
Thickening efficiency: The presence of electrolyte will reduce the thickening efficiency of carbomer resin. Carbomer 940 is sensitive to salt and cations. When the soluble ion concentration in the component is greater than 0.1%, the component should be appropriately reduced. dosage. Deionized water can be used as the matrix of the main material, and salt is added after neutralization to grasp the degree of influence of salt on the system;
Transparency: When there are insoluble components, it is difficult for the Kabo 940 system to present a clear and transparent gel, and the solubilization technology can reduce or eliminate this effect;
Production equipment requirements: Carbomer 940 is thickened by forming a gel skeleton. After carbomer is neutralized, high shear stirring, persistent stirring, grinding or pumping will destroy its skeleton and cause viscosity loss , should use pipeline homogenizer, use low shear pumping, such as reciprocating diaphragm pump or gear pump;
Ultraviolet irradiation: long-term ultraviolet irradiation will reduce the viscosity of carbomer resin;
Dealing with the problem of spillage: Carbomer is a polyelectrolyte, and rubbing or squeezing the resin particles will sometimes cause static electricity. In case of spillage, please use a broom to sweep up the dry powder first, and do not rinse with water, otherwise it will form a slippery gel on the ground or equipment.
The aqueous solution of Carbomer 940 itself is acidic, and it does not have the ability to thicken before neutralization, and the liquid is opaque and translucent. After mixing, the carbomer liquid immediately turned into a transparent gel, and the viscosity increased rapidly;
The swelling speed of Carbomer 940 in water is slow. It can swell in cold water or in hot water. The swelling speed in hot water is slightly higher than that in cold water. It takes about 1 hour to 3 hours to fully swell 0.2% carbomer 940 in 100g of water. The larger the total amount, the longer the complete swelling time. The higher the concentration of carbomer 940, the longer the complete swelling time. ;
During the swelling process of Carbomer 940, the standard for complete swelling is that the neutralized Carbomer 940 is applied to the hands, the material body is clear and transparent, and the surface of the material body is smooth without rough grain; if there is transparency during the application process Round particles indicate that Carbomer 940 is not fully swollen;
In order to ensure the complete swelling of Carbomer 940, the judgment criteria are: (1) The material body has no obvious lumpy particles visible to the naked eye (2) The material body hangs on the wall of the beaker and the liquid is completely uniform without visible particles (3) Neutralization After smearing on the hands, there are no transparent round particles visible to the naked eye. At this time, Carbomer 940 is completely swollen, and the subsequent process operations can be carried out.
