Fatty Alcohol Ethoxylate Applications

Polyoxyethylene alcohols from Rimpro India's fatty alcohol ethoxylate range serve as wetting agents, emulsifiers and detergency aids across household, industrial, agricultural and specialty applications.

A. Household Surfactants

The largest outlet for polyoxyethylene alcohols is in the formulation of cleaners for household and industrial use. They can be compounded as liquids, powders, pastes, or bars depending upon the specific application: laundry detergent formulations, automatic dishwashing-machine detergent, hand washing formulations, solid hard-surface (dry powder) formulations, floor cleaner and wax stripper (liquid) formulations, and waterless hand cleaner formulations.

B. Industrial Surfactants - Textile

Scouring

In the textile-scouring operation for both natural and synthetic fibers, nonionics based on alcohols have played a very important role. Wool-scouring, cotton kier boiling-off of viscose, and soaping-off are examples of some of the types of scouring operations. The polyoxyethylene alcohols are normally used in the 0.1 to 1.0% concentration range plus some polyphosphates, silicates, or other alkali. By use of the nonionic, the scouring time is reduced and soap "curds" are eliminated.

Lubricating

Since the scouring operation removes the fats present in the initial material, materials have to be added back which will serve as lubricants, softeners, and antistatic agents for the carding, spinning, and weaving operations. Mineral oil and/or vegetable oil are normally used as lubricants.

Dyeing and Finishing

The largest surfactant-consuming step in cotton processing is the dyeing and finishing step. Polyoxyethylene alcohols play an important role in this process, owing to their action as penetrants, wetting agents, and dyeing assistants. The mode of action of dyeing assistance seems to involve the agglomeration of dyestuff molecules into micelles, and polyoxyethylene alcohol serves well in this capacity.

C. Agricultural

Nonionics are excellent emulsifiers for agricultural sprays because they are unaffected by hard water and by pH changes. The general types of agricultural sprays are the "ready-to-emulsify" hydrocarbon solutions of various insecticides and plant toxicants such as DDT, Parathion, Chlordane, Toxaphene, 2,4-D and 2,4,5-T esters. Sprays of this type are sold as emulsifiable concentrates and are usually diluted with water at the time of application. The hydrocarbon is utilized to dilute the toxicant to safe strength or to keep the material in liquid form. Polyoxyethylene alcohols are very useful in this application.

D. Paper

Polyoxyethylene alcohol finds a number of uses in the paper industry. Rewetting agents such as RIMPRO TA-9.5 are used to improve the absorbency of wet-strength paper, i.e. paper towel. RIMPRO TA-9.5 is also used for the rapid penetration of treating solutions into impregnated paper or box board. Polyoxyethylene alcohol is also used in the pulping of old paper, as well as in the de-inking of old newsprint.

E. Rubber

Polyoxyethylene alcohols are excellent stabilizers for rubber latex during compounding operations.

F. Leather

Normally, leather goes through four basic processing operations - degreasing, tanning, fat-liquoring and finishing. In each operation the use of a surfactant, particularly the polyoxyethylene alcohol, is helpful.

G. Paints

The use of wetting agents and emulsifiers in the emulsion polymerization of base lattices is well-known. The choice of a particular surfactant depends on the particular monomer being reacted and the properties desired in the final emulsion. Polyoxyethylene alcohols, as well as other nonionics, are superior emulsifiers because of their tolerance for hard water.

In paint-formulating operations, stabilized latex emulsions are sometimes subject to coagulation with severe agitation or milling. The use of polyoxyethylene alcohol such as RIMPRO LA-4 and RIMPRO LA-23 overcomes this problem.

H. Cosmetics

Polyoxyethylene alcohol finds a number of uses in the manufacture of cosmetics raw materials, such as in shampoos, skin cleansers, skin compatibility, normal flora, antibacterial wash products, most sodium lauryl ether sulfate, and different types of emulsifying waxes etc.
