Description of MOA  Polyethoxylated fat alcohols  :

Physical property

Water solubility: polyoxylated fatty alcohols have good water solubility, and their solubility parameters are similar to water, so they show good solubility in aqueous solutions. This property makes PEG widely used in pharmaceutical, cosmetic, food and bioengineering fields.

Viscosity: The viscosity of polyoxylated fatty alcohols increases with molecular weight. At a certain concentration, PEG with high molecular weight showed higher viscosity. This property allows PEG to be used as a lubricant, rust inhibitor, paint, etc.

Temperature sensitivity: The aqueous solution of PEG is temperature sensitive; that is, the solubility of PEG in water decreases as the temperature increases. This property makes PEG potentially useful in drug delivery and controlled release systems.

Biocompatibility: PEG is compatible with organisms and does not cause significant immune responses. This property makes PEG widely used in drug delivery, tissue engineering and biomedical engineering.

Stability: Polyoxylated fatty alcohol has good thermal and chemical stability and is highly stable in acids, bases, oxidants, and other reagents. This property allows PEG to remain stable in some extreme environments.

Chemical properties

Oxidation reaction: Under certain conditions, PEG can undergo an oxidation reaction to generate corresponding polyoxy compounds. This property allows PEG to be used as an oxidant or initiator in some chemical reactions.

Esterification: polyoxylated fatty alcohols can be esterified with carboxylic acids to produce ester compounds. This property gives PEG potential application value in preparing polymer materials and surface coatings.

Etherification reaction: PEG can etherify with alcohols to form ether compounds under certain conditions. This property makes PEG also have potential application value in preparing polymer materials and surface coatings.

Acylation reaction: Under certain conditions, PEG can be acylated with acid anhydride or acyl chloride, etc., to generate the corresponding acylates. This property makes PEG also have potential application value in preparing polymer materials and surface coatings.

Applications of MOA Polyethoxylated fat alcohols：

Medical field

Drug carrier: polyoxylated fatty alcohol as a drug carrier can improve the solubility, stability and bioavailability of drugs. At the same time, PEG has good biocompatibility and low toxicity, which makes the drug have a better therapeutic effect and lower side effects in vivo.

Gene delivery: PEG can be used as a carrier for gene delivery, combining with DNA or RNA to form a complex to improve the efficiency and expression level of genes in the cell. This application has important implications for gene therapy and genetic engineering.

Medical device coating: PEG can be used as a coating material for medical devices to improve the biocompatibility and anti-contamination performance of the device. For example, PEG coatings can reduce protein adsorption and cell adhesion of medical devices in the body, thereby reducing the risk of infection.

Cosmetics

Moisturizer: Polyoxylated fatty alcohol has good moisturizing properties, which can lock the skin with moisture and keep it moist. Therefore, PEG is often used as a moisturizer in cosmetics.

Emulsifier: PEG can evenly disperse oily and water-based ingredients in cosmetics to form a stable emulsion. This application makes cosmetics more excellent in texture and feel.

Thickener: PEG can be used as a thickener to improve the viscosity and stability of cosmetics. This makes the makeup smoother and easier to control when applied.

The food industry

Food additives: polyoxylated fatty alcohols can be used to improve the taste and texture of food. For example, PEG can be used as an emulsifier, stabilizer, and thickener for food.

Food packaging: PEG can be used as a coating for food packaging materials to improve the moisture resistance, oil resistance and oxidation resistance of the packaging. This helps to extend the shelf life of food and improve food safety.

Bioengineering

Tissue engineering: polyoxylated fatty alcohol can be used as a cell culture substrate in tissue engineering to provide a suitable growth environment for cells. At the same time, PEG can also be used as a carrier for cell transplantation to improve cell survival rate and transplantation effect.

Biosensors: PEG can be used as a coating material for biosensors to improve the sensitivity and stability of sensors. This application is of great significance for biomedical research and clinical diagnosis.

Chemical industry

Synthetic materials: polyoxylated fatty alcohols can be used as important raw materials for preparing high molecular polymers, surfactants, lubricants, etc. These products are widely used in chemical, textile, paper and other fields.

Coatings and inks: PEG can be used as an additive in coatings and inks to improve the leveling, gloss and weather resistance. This makes the paint and ink more excellent in appearance and performance.

Plastic processing: PEG can be used as an additive in plastic processing to improve the processing performance of plastics and the quality of finished products. For example, PEG can be used as a plasticizer for plastics, an antistatic agent, a lubricant, etc.

Production Method of MOA Polyethoxylated fat alcohols：

Alcoholysis process

Alcoholysis is one of the earliest methods to produce polyoxyeated fatty alcohols. The method takes fatty alcohol as raw material and reacts with ethylene or propylene oxide under a catalyst to produce the corresponding polyoxyethylene fatty alcohol. The catalysts are usually sodium hydroxide, potassium hydroxide, or sulfuric acid. The advantages of this method are that it is a simple process, requires low equipment investment, has high product purity, and can be used to produce high molecular weight PEG. However, the disadvantages of alcoholysis are higher raw material costs, more by-products, the need for post-treatment and separation, and the operation is more difficult.

Esterification method

Esterification is another commonly used method for producing polyoxylated fatty alcohols. The method takes fatty acid or fatty acid ester as raw material and esterifies it with ethylene oxide or propylene oxide to produce the corresponding polyoxylation of fatty acid ester. Then, the polyoxylated fatty alcohol was obtained by hydrolysis. The advantages of esterification are wide sources of raw materials, low cost, fast reaction rate, and the fact that it can produce low molecular weight PEG. However, the disadvantage of esterification is that more by-products require post-processing and separation, and the product purity is low.

Etherification method

Etherification is a new method developed recently to produce polyoxylated fatty alcohols. The method takes fatty alcohol or adipose ether as raw material, etherizes with ethylene oxide or propylene oxide, and produces corresponding polyoxyethylated adipose ether. Etherification has the advantages of a wide source of raw materials, mild reaction conditions, and can be used to produce high molecular weight PEG. In addition, the etherification method can adopt a continuous production mode, which improves production efficiency and product purity. However, the disadvantages of etherification are the need to use special catalysts and higher reaction temperatures, more by-products, and the need for post-processing and separation.

Microbial fermentation method

Microbial fermentation is a biosynthetic process that can produce polyoxyethylated fatty alcohols. The method uses microbial strains as catalysts to convert glucose or other carbon sources into polyoxylated fatty alcohols. The advantages of microbial fermentation are a wide range of raw materials, an environmentally friendly production process, and high product purity. In addition, by screening and modifying microbial strains, the performance and yield of the product can be further improved. However, the disadvantage of microbial fermentation is that the production cycle is longer, the fermentation conditions are higher, and post-processing and separation are required.
