  Alpha olefin sulfonate is a formaldehyde-free solution of sodium c14-c16 that preserved by mCi/MI. It has excellent viscosity, hard water stability, detergency, foam characteristics and pH stability in wide pH range, so it can be used in many applications. Compared with lauryl sulfate, alpha olefin sulfonate is a mild surfactant, which can be used in high performance sulfate free, shampoo, shower gel, hand sanitizer and pet care formula. It is very effective in unloading poor fluids and particles from gas producing wells. It has excellent thermal stability at temperatures up to 400 ° F. The product is easily biodegradable. Ordinary alpha olefins are excellent intermediates for the production of  alpha olefin sulfonate  (AOS) surfactants. These surfactants have excellent detergency, high compatibility with hard water, good wetting and foaming properties. AOS does not contain skin irritants and sensitizers, and it can be rapidly biodegraded. It is used in high quality shampoo, light li

  Polyether polyol is mostly used to manufacture soft, hard and semi-rigid polyurethane foams. Polyether polyol  is not only easy to obtain raw materials with low cost, but also hold good properties of synthetic polyurethane foam.It is the polyol  raw material  with the largest dosage for polyurethane foam industry. 1. Polyether polyol for soft foam Polyether polyol  used for soft foam is generally long-chain polyether with low functionality. The functionality of polyether polyol in soft foam formula is generally 2 ~ 3, and the average molecular weight is between 2000 ~ 6500. Polyether triol is the most commonly used in soft foam. Generally, glycerin (glycerol) is used as RXH, which is obtained by ring-opening polymerization of 1, 2-propylene oxide or copolymerization of propylene oxide with a small amount of ethylene oxide. The molecular weight is generally in the range of 3000 ~ 7000. Glycerin are mainly used  soft foam with high resilience, and can also be used in foam products such

  The following points should be noted when using propionyl chloride in China   1. Overview of hazards Health hazard: its vapor has a strong irritation to respiratory tract and eyes, and causes cough and dyspnea after inhalation. It can also cause skin burns.   Flammability hazard: this product is flammable, poisonous and highly irritating.   2. First aid measures Skin contact: Immediately take off contaminated clothing and rinse with plenty of running water for at least 15 minutes. Go to a doctor.   Eye contact: Lift the eyelid immediately and rinse thoroughly with plenty of running water or normal saline for at least 15 minutes. Go to a doctor.   Inhalation: Quickly leave the scene to fresh air. Maintain airway patency. If breathing is difficult, give oxygen. If breathing stops, give artificial respiration immediately. Seek medical advice.   Ingestion: Rinse mouth with water and drink milk or egg white. Seek medical advice. 3. Fire control measures Dangerous characteristics: the vapo

  The DMC catalyst has a freezing point of 4 ℃ and a boiling point of 90 ° C. It is a colorless transparent liquid with a slight aromatic smell at room temperature. It is easy to volatilize and has the appearance similar to alcohols, esters and ketones. It can be miscible with organic solvents in any proportion, such as alcohol, ester, ketones. It is non corrosive and partially soluble in water with a solubility of 13.9g/100gH2O. Water can also be partially soluble in DMC with a solubility of 4.2gH2O/100gDMC.       Single bimetal cyanidation has no catalytic activity, and only DMC complex formed by DMC and ligand complexation can show catalytic activity. The zinc-Cobalt cyanide complex is the most suitable for the preparation of  polyether polyol  with low unsaturation and narrow relative molecular weight distribution.   DMC catalyst  is a kind of non-toxic chemical raw material with excellent environmental protection performance and wide application. It is an important intermediate in

  Cocoamido propil betaina is a kind of light-yellow cleaning fluid that has excellent stability under acidic and alkaline conditions. It is cationic in acidic media and anionic in alkaline media. It can be compatible with various types of dyes, surfactants and cosmetic raw materials. In addition, it has excellent decontamination, softness, foaming, wetting and antistatic properties. At the same time, it has good hard water resistance and corrosion inhibition to metals.   Cocoamido propil betaina  has good cleaning and conditioning properties, which is why it is also called  cocamidopropyl betaine amphoteric surfactant . It is compatible with anionic, cationic and nonionic surfactants. It has the characteristics of low irritation and mild performance. At the same time, its foam is thin and stable. It is suitable for the production of shampoo, shower gel and facial cleanser. And it can be used to enhance the softness of hair and skin.   When cocoamido propil betaina is used in combinati

  Anionic surfactant is a kind of product with the longest history, the largest output and the most varieties among surfactants. According to the structure of hydrophilic groups, anionic surfactants can be divided into sulfonates and sulfates, which are the main categories of anionic surfactants.    The  anionic surfactants definition  is a must-known concept for many people working in the chemical industry. The various functions of surfactants are mainly manifested in changing the properties of the liquid surface, liquid-liquid interface and liquid-solid interface, of which the surface (interface) of the liquid is the most important.   Sulfate-type anionic surfactants mainly include fatty alcohol sulfate (also known as primary alkyl sulfate) and secondary alkyl sulfate ： 1.  Fatty alcohol sulfate (ester) salt (FAS or AS). The general formula of fatty alcohol sulfate is: ROS0-3M+, R is alkyl, M+ is sodium, potassium, ammonium, ethanolamine and other cations, also known as primary alkyl
