Carbomer 940
Carbomer 940 is white and loose; it is acidic, hygroscopic and slightly smelly. It is soluble in water, ethanol, and glycerin. The usual concentration is 0.1% - 3.0%. Carbomer 940 contains a large number of carboxyl groups in its molecule, so the aqueous solution should be used after neutralization with alkali to reduce the irritation to the skin and mucous membranes. The neutralizer of Carbo 940 can be sodium hydroxide, potassium hydroxide, potassium bicarbonate, borax, amino acids, polar organic amines such as triethanolamine. Laurylamine and stearylamine can be used as neutralizers in non-polar systems. The neutralized carbomer hydrogel is the most viscous between pH 6-11, such as pH12, the viscosity will decrease, and the presence of strong electrolytes can also reduce the viscosity. The gel is unstable, and it is easy to grow mold and lose viscosity when exposed to the sun. Adding antioxidants can slow down the reaction. How to use Kabo 940 (acrylic resin) and matters needing attention: 1.pH value: The optimum pH value range of Carbo 940 system is 4-10, higher or lower than this range will lead to changes in system viscosity. 2.Components that are not easily compatible in the formula: protein, PVP resin, polyethylene glycol (PEG), polyethoxylated surfactant will interact with unneutralized Carbo 940, so it needs to be partially neutralized before adding Capo 940. Desheng professionally provides cosmetic raw materials and technical formula support such as Carbo 940. 3.Salt and soluble cations: Carbo 940 is sensitive to salts and cations. When the concentration of soluble ions in the component exceeds 0.1%, the dosage of the component should be controlled. If possible, use acidic, neutral or alkaline materials as the matrix of the main drug, use deionized water, add salt after neutralization to grasp the degree of salt's influence on the system, high-valent ions (Ca, Mg, Fe, AI) will Serious damage to the system should be eliminated. Self-converted pollutants (such as Fe, Cu, etc.) will gradually reduce the viscosity of the system and cause the system to become unstable. Preparation of products in stainless steel or non-metal equipment will avoid this situation. In addition, adding EDTA to chelate metal ions can also achieve good results. In addition to the above two aspects, a suitable model of Carbo 940 (such as Carbo 9401342GE resin) can also be used, which has low sensitivity to soluble salts. 4. Insoluble matter: When insoluble components are present, it is difficult for the Carbomer 940 system to present a clear and transparent gel.

CARBOMER is an acrylic polymer containing polyenyl polyether crosslinked. It is a white loose powder with strong hygroscopicity. Due to the carboxyl group in its molecular structure, it has a certain acidity, which can be neutralized by alkaline substances to form transparent gel. After the carboxyl group was neutralized and ionized, the molecular chain was dispersed and extended due to the mutual repulsion of negative charges. The thickening effect of capo resin can be produced in very low dosages. Kapoor resin enables liquid systems to have special yield values and rheological properties. Some insoluble additives (particles, oil droplets, etc.) can be suspended at very low concentrations. Because of its suspension ability, kapoor resin is widely used to stabilize traditional oil/water emulsions and creams, oil droplets in suspension solutions and water insoluble substances. The viscosity of Carbomer gel is positively correlated with the concentration, and the higher the concentration, the higher the viscosity of the gel. Carbomer gel is sensitive to electrolyte ions, and the viscosity of carbomer gel decreases sharply with the presence of electrolyte ions, and the effect of divalent ions is greater than that of monovalent ions. The decrease in viscosity of carbomer gel caused by ion is mainly because it reduces the mutual repulsion of the same charge on the main chain of the polymerization, thus reducing the actual effective concentration of carbomer in the system. performance It has the effect of thickening, suspension and stability With short flow (3) With high transparency The viscosity of capo resin is not affected by temperature Local administration system, crystal clarifying gel, water or alcohol solvent Application field Skin lotion and cream (2) Transparent gel products containing ethanol Transparent skin care gel, hair styling gel Shampoo and shower gel Rub mud treasure to remove cutin Suggested usage 0.2% ~ 1.0% Matters needing attention (1) After capo neutralization, persistent stirring or high shear stirring will cause viscosity loss The presence of electrolyte can reduce the thickening efficiency of capo resin Long-term ultraviolet radiation will reduce the viscosity of capo resin Packing and storage Packing: 20kg/ case Storage: keep in ventilated and cool place
