Hydroxypropyl Methyl Cellulose
Also known as: Hpmcd
Hydroxypropyl methylcellulose is the propylene glycol ether of methylcellulose, in which hydroxypropyl and methyl are combined by ether bond and anhydrous glucose ring of cellulose, which are white to gray white cellulose powder or particles, with the characteristics of cold water dissolution and hot water insolubility similar to methylcellulose. The solubility in organic solvent is better than that in water. It can be dissolved in anhydrous methanol and ethanol solution, and also in chlorinated hydrocarbons and ketones and other organic solvents. Soluble in water, its aqueous solution has surface activity, and after drying, it forms a thin film. After heating and cooling, it can undergo reversible conversion from sol to gel. It can be used alone or in combination with other emulsifiers and stabilizers in cold drinks. The maximum dosage of cold drinks is 1%. Hydroxypropylmethylcellulose can be mixed with other water-soluble polymer compounds to form a uniform and transparent solution with higher viscosity. The gelation temperature of low viscosity products is higher than that of high viscosity. Its solution is stable when stored at room temperature. In recent years, it has been widely used in petrochemical, papermaking, leather, textile printing and dyeing, medicine, food, cosmetics and other industries as dispersant, thickener, adhesive, excipient, capsule, oil-resistant coating and filler.

2-Ethylhexanol
2-ethylhexanol is often called octanol in the neighborhood of plasticizer. It is an important chemical raw material. In addition to the production of plasticizers, foreign octanol can also be used to produce octyl acrylate or surfactant. It can be mainly used to produce: DOP, DOA, totm, other plasticizers, octyl acrylate, surfactants, bone oil additives, mining, diesel engine fuel additives, solvents and formulations Rust inhibitor ester and other chemicals. Octanol itself is a useful solvent, defoamer, dispersant and lubricant. Its series products are mainly plasticizer such as dioctyl phthalate and octyl acrylate. Dioctyl phthalate produced from octanol is the main plasticizer of PVC. The consumption of dioctyl phthalate for PVC accounts for 95% of the total consumption.
2-Phenoxyethanol
Phenoxyethanol is an organic compound often used in skin care products. It can be synthesized by etherification of glycol and phenol. It is commonly used in skin care cream and sunscreen. Phenoxyethanol is a colorless, slightly viscous liquid with aromatic odor, slightly soluble in water, easily soluble in ethanol and sodium hydroxide. It has antibacterial effect (generally used with quaternary ammonium salt), and is often used as a substitute for highly toxic sodium azide in biological buffer solution, because 2-phenoxyethanol has low toxicity and is not chemically active to copper and lead. In cosmetics, skin care products, vaccines and drugs, they usually play the role of preservatives.
Allantoin
Allantoin has anti-inflammatory and analgesic effects, and it also has weak local paralysis effect, which can effectively reduce the stimulation of irritants. It can be used as a skin protection agent and anti irritant, which can reduce the stimulation of cosmetic ingredients on the skin. China food and drug administration has listed it as the first type of high-efficiency active group skin care agent, which has been widely used in shampoo and sunscreen products Cream products, shaving cream and oral care products.
Azelaic Acid
Azelaic acid is a skin disease prevention and treatment drug, mainly used for acne, chloasma and skin melanin deposition. It is also an important organic synthesis intermediate. It is also used in plastics, rubber and other industries to synthesize plasticizers, aviation oil to synthesize low-temperature high-speed lubricating oil, electrolytic capacitor manufacturing and other aspects. At present, the main production method is to prepare azelaic acid from unsaturated fatty acids such as oleic acid and triglycerides such as castor oil and cottonseed oil.
Benzoic Acid
Benzoic acid, also known as benzoic acid, has a molecular formula of c6h5cooh. The simplest aromatic acid with the carboxyl group directly linked to the carbon atom of the benzene ring is a compound formed by the substitution of hydrogen on the benzene ring by the carboxyl group (- COOH). It is colorless and tasteless lamellar crystal. Melting point 122.13 ℃, boiling point 249 ℃, relative density 1.2659 (15 / 4 ℃). When it sublimates rapidly at 100 ℃, its steam has a strong irritant, which is easy to cause cough after inhalation. Slightly soluble in water, easily soluble in ethanol, ether, chloroform, benzene, toluene, carbon disulfide, carbon tetrachloride, turpentine and other organic solvents. In the form of free acid, ester or its derivatives, it exists widely in nature, for example, in the form of free acid and benzyl ester in benzoin gum; it exists in some plant leaves and stems and leaves in a free form; exists in methyl oil or benzyl ester in essential oils; in horse urine, it exists in the form of its derivative, uric acid. Benzoic acid is a weak acid, stronger than fatty acid. Their chemical properties are similar, and they can form salts, esters, acyl halides, amides, anhydrides, etc., which are not easy to be oxidized. The electrophilic substitution reaction can take place on the benzene ring of benzoic acid, which is mainly produced by the intermediate substitution. Benzoic acid is often used as medicine or preservative, which can inhibit the growth of fungi, bacteria and molds. It is usually applied on the skin for the treatment of ringworm skin diseases. Used in synthetic fiber, resin, coating, rubber, tobacco industry. At first, benzoic acid was prepared by carbonization of benzoin gum or hydrolysis of alkaline water, or hydrolysis of hippuric acid. In industry, benzoic acid is produced by oxidation of toluene with air in the presence of cobalt, manganese and other catalysts, or by hydrolysis and decarboxylation of phthalic anhydride. Benzoic acid and its sodium salt can be used as bacteriostatic agent of latex, toothpaste, jam or other food, and as mordant of dyeing and printing
