Abstract

A process for prepg. industrial creamlike detergent comprises (a) heat-concentrating the mixt. of ethanolamine derivs. of 30-40 wt.%, ethyleneoxide aq. soln. of 0-10 wt.% and coconut oil of 0-10 wt.% added with ethyleneoxide at 40-90 deg.C, adding kaoline of 10-30 wt.% and stirring for 3hr at 50 rpm; (b) mixing urea of 10-30 wt.%, reducible bleacher of 10-20 wt.% and additive (skin protector, stabilizer, perfume) of 0.02 wt.%; and (c) mixing (a)- and (b)-soln. with a stirrer (50 rpm) for 1hr.

Description

Manufacturing method of creamy industrial detergent

The present invention provides a weak alkaline industrial adsorbent for adsorbing solvents of ethanolamines with good biodegradability and palm oil added with ethylene oxide to kaolin to remove skin and fibers contaminated with industrial pigment oils by washing and rubbing. It relates to a method for producing a cream detergent.

In general, when dyes are contaminated with skin or textiles in a printing factory, sodium hydrosulfide, urea and caustic soda are dissolved in water and wiped off with a brush.In this case, the solution is strongly alkaline and causes degreasing or drying on the skin. This may cause a rupture, which may cause disadvantages to the worker. In addition, conventional synthetic detergents may cause a large amount of foam during washing, which may cause difficulty in rinsing, and also cause large amounts of phosphate to be released during washing. It is a fact that water pollution has also caused pollution problems.

The present invention is to absorb bleaching action by using a weakly alkaline reducing agent to adsorb the palm oil added to the biodegradable ethanolamines and ethylene oxide to the kaolin to solve the conventional defects, and to industrialize the bleaching action The purpose of the present invention is to obtain a detergent for cleaning skin and fibers contaminated with pigments and oils, which are described in detail by the following manufacturing process.

First step: 30-40 parts of ethanol amine derivative, 10-0 parts of ethylene oxide aqueous solution, 10-0 parts of palm oil to which ethylene oxide was added were heated and concentrated at 40-90 ° C., and then 30-10 parts of kaolin was added thereto. Stir and adsorb slowly with RPM 50 for 3 hours to cool it to room temperature.

Second process: 10-30 parts of urea, 10-20 parts of reducing bleach and 0.02 parts of additives (anti-contamination agent, skin protectant, stabilizer, fragrance) are added and the RPM together with the contents obtained in the first process described above. Slowly stir at 50 for 1 hour to obtain a creamy detergent.

The present invention obtained by the above process has good biodegradability and weak alkaline antifoaming, so that foam does not form during washing, so rinsing is good, and the biodegradability is good, so that water and oil and the like are separated from each other. Since no floating layer is formed in the group, the floating layer is prevented from sticking to the inner circumferential surface of the washing container after washing, and it is free from volatile and does not contain any phosphate. It contains a skin protection agent and prevents skin degreasing or dry rupture caused by using a detergent as in the prior art, but there is no fear of damaging the skin even without using gloves when washing.

In the present invention, by adsorbing palm oil added ethanol amines and ethylene oxide having good biodegradability to kaolin, it reacts with water to enhance the effect of bleaching and washing by oxidation and reduction reactions, and at the same time, its use is simple. It is a new useful invention of pollution prevention that is greatly helped.
