Some information about Isomeric alcohol ethoxylates

October 08,2021

Many people are unfamiliar with isomeric alcohol ethoxylates, but you don't know that this chemical product is widely used in our daily life. Let's follow this blog to take a look!

 

Definition

 

Isomeric alcohol ethoxylate is a kind of chemical product as a surfactant. It is mainly divided into isomeric deca alcohol polyoxyethylene ether, isomeric undecyl alcohol polyoxyethylene ether, isotridecyl alcohol polyoxyethylene ether, etc. It is widely used in textile industry, leather, daily chemical washing, etc. It is an efficient dispersant, wetting agent and emulsifier.

Usage

 

The isomeric alcohol ethoxylate is a colorless or light yellow liquid, easily soluble in water, has little skin irritation, and has good biodegradability. The lipophilic group of the isomeric alcohol ethoxylate is a branched fatty alcohol. Compared with linear alcohols, it has low freezing point, low surface tension, and high critical micelle concentration, so it has strong penetrating power, fast diffusion in water, and high concentration is not easy to form gel. Used in concentrated and super concentrated liquid detergent formulations, it can greatly improve the product's low temperature stability and decontamination performance.

 

Among the homologous surfactants of isomeric alcohol ethoxylate, isomeric C13 alcohol polyoxyethylene ether has the best decontamination performance. Isomeric alcohol polyoxyethylene ether is still a transparent solution when the mass fraction of active substance is 50%. . At the same time, it also shows good solution stability when it is compounded with AES or AEO. In winter, the water temperature is low, especially below 10 ℃, the water-soluble dispersibility of highly concentrated laundry detergent is reduced, which affects the decontamination performance of the product. The pour point of isomeric alcohol ether is generally lower than that of AEO, especially 7 or 9 EO plus the pour point of several non-ionic surfactants and isomeric alcohol ethers is lower than 15℃, and the lowest can reach 5℃, which can meet the normal use of consumers in most parts of the country. Another important feature of isomeric alcohol polyoxyethylene ether is that it has good water-soluble dispersibility at low temperature, and when it is compounded with AEO or AES in an appropriate ratio, it can greatly improve the low-temperature water solubility of concentrated laundry detergent.
