Chemal LA-4 is primarily recommended for evaluation in wetting, detergent, and emulsifying applications.
Chemal LA-4 is a nonionic surfactant belonging to the group of ethoxylated fatty alcohols, INCI name: Laureth-4. This product is based on lauryl alcohol and has a chemical description of “alcohols, C12-16, ethoxylated”. Chemal LA-4 is most commonly used as an emulsifier in industrial formulations which include metalworking fluids. It may also be used in textile and cleaning applications wherever there is a need for the formation of a stable emulsion. This chemistry is frequently used as raw material for the production of phosphate esters and carboxylates.
Chemal LA-4 is a clear to cloudy liquid with a maximum color of 1 Gardner at 25°C. The product is sold in 100% active form which may become a soft paste when cooled. Low heat and mild agitation will easily restore the material to homogeneity if this happens. Chemal LA-4 forms a cloudy solution in water.
This product is characterized by an HLB value of 9.2 and may be mixed with other nonionic, cationic, or anionic agents. Due to the long carbon chain and low ethylene oxide content, Chemal LA-4 also provides lubricity attributes with minimal foam generation. The product exhibits excellent wetting properties with a Draves wetting speed of 30 seconds.
PCC Chemax Inc. is specialized in the production of surfactants and chemical specialist additives used, i.a. in the metallurgical, textile, refinery and mining, and plastics industry.
