KR900002927B1 - A process for the preparation of creanlike detergent for removing oil - Google Patents

Abstract

A process for prepg. creamlike detergent for removing oil comprises (a) heat-concentrating the mixt. of ethanolamines of 30-40 wt.%, ethyleneoxide aq. soln. of 0-10 wt.% and coconut oil of 0-10 wt.% added with ethyleneoxide for 3hr at 40-90 deg.C; (b) mixing kaoline of 20-30 wt.%, urea of 20-30 wt.% and additive (stabilizer, skin protector, perfume); and (c) adding the (b)-soln. to the (a)-soln. in a stirrer (at 50 rpm for 3hr) at 40-90 deg.C, and cooling at room temp.

Description

Manufacturing method of cream detergent for oil removal

The present invention is not only to remove industrial oils or fats contaminated with skin, but also to remove various kinds of tools and metal oils with foreign matter on the surface of Kaolin to easily remove them by washing or rubbing. It relates to a method for producing a weak alkaline cream detergent obtained by adsorbing amines.

Generally, synthetic detergents used for household and industrial use are mainly composed of alkyl benzene sulfonate (A.B.S), which is low in biodegradation, and causes large amounts of phosphate to cause pollution due to water pollution. The use of ABS-based detergents is known to cause skin degreasing and contact dermatitis due to skin toxicity, which requires the wearing of protective gloves. Such conventional synthetic detergents generate a large amount of foam during washing. Not only is it difficult to rinse, but it is also lacking in economy as an excessive amount of water and time required for rinsing.

The present invention is to provide a weak alkaline deodorizing cream detergent having a good detergency, biodegradability to improve the rinsability during washing in order to eliminate the defects in the conventional synthetic detergent as described above. If it is described in detail by the following manufacturing process as follows.

First step: 40-30 parts of ethanolamines, 10-0 parts of aqueous ethylene oxide solution, and 0-10 parts of palm oil to which ethylene oxide was added are concentrated by heating at 40-90 ° C. for 3 hours, and then cooled at room temperature.

Second step: 20-30 parts of kaoline and 30-20 parts of urea are mixed with the contents obtained in the first step, but 0.1 part of an additive (stabilizer, skin protectant, fragrance) is mixed, wherein 40- After slowly mixing at 50 ° C. for 3 hours at 90 ° C., the mixture is cooled to room temperature to form a creamy detergent.

The creamy detergent of the present invention obtained by the above-mentioned process does not use phosphate at all and contains a skin protective agent, which does not cause skin degreasing or contact dermatitis, but also has a low volatility, so there is no fear of fire, and the present invention is biodegradable Because of its weak alkaline defoaming properties, washing rinsing is less likely to generate bubbles, so there is no fear of wasting excess water and time when rinsing laundry. It is a novel invention to increase the actual value of use as there is no fear of pollution compared to the conventional synthetic detergents because it is also formed as a group does not generate a floating layer to cling to the washing container even after washing.
