Abstract
The present invention relates to a kind of synthetic detergent powder, it is characterized in that it must comprise tensio-active agent and a kind of washing assistant that is selected from cross-linking starch, amyloform and hydroxypropylated starch.These detergent raw material wide material sources, cost are lower, free from environmental pollution, and washing effect is good, and strong detergency is suitable for producing on a large scale and using.
Description
The present invention relates to a kind of detergent composition, more specifically say to relate to a kind of synthetic detergent powder that adopts modified starch as washing assistant.
Existing synthetic detergent powder is of a great variety, but they include tensio-active agent (negatively charged ion, nonionic surface active agent), yellow soda ash, sodium sulfate, tripoly phosphate sodium STPP, Xylo-Mucine, white dyes and water glass or the like usually, and wherein main washing assistant is a tripoly phosphate sodium STPP.Because China's phosphate rock resource poorness needs to satisfy the needs that washing powder is produced from external import tripoly phosphate sodium STPP.In addition, use the washing powder that contains tripoly phosphate sodium STPP, its waste water drains in the rivers, can cause the ramp of phycophyta, and the natural eubiosis is destroyed.At present, developed some non-phosphide detergents abroad and be intended to overcome above-mentioned deficiency, typically comprised: tensio-active agent, carboxymethyl cellulose, water glass, sodium sulfate, yellow soda ash, 4A type zeolite or Grautrez S-95 polymkeric substance, optical whitening agent etc.These prescriptions are science and practicality not to the utmost all, because of external kinds of surfactants is various, but costs an arm and a leg mostly, and the domestic market is unavailability all; Zeolite is natural or synthetical silicate (aqueous zirconium, uranium, barium, strontium and potassium) in addition, and it is water insoluble, and clothing is had damage and can stop up the washing machine drainage system.And in the washing powder production process of the type that dusts, can stop up the Spray gun nozzle of spraying, so also not can be made into the washing powder of the type that dusts.United States Patent (USP) the 4th, 116, No. 854, the 4th, 169, No. 064, the 3rd, 756, No. 966 and the 4th, 029, all proposed a kind of washing powder in No. 590, but described starch generally is water-insoluble starch, at most it is carried out dextrinization and handle with starch replacement phosphide or nitride.General starch is owing to water insoluble, so after having used the washing powder that contains general starch, insoluble part can remain on the clothing, causes difficulty to rinsing.
The object of the present invention is to provide a kind ofly to replace the synthetic detergent powder of tripoly phosphate sodium STPP component, can reduce production costs and pollute, but do not influence the soil removability of synthetic detergent powder with modified starch.
The present invention realizes by such design: a kind of synthetic detergent powder, it comprises tensio-active agent (negatively charged ion, nonionic surface active agent) washing assistant and auxiliary agent etc., said washing assistant is a modified starch, said modified starch is selected from the group of being made up of cross-linking starch, amyloform or hydroxypropylated starch, and its amount ranges is in 20% to 40%(weight) between.Washing assistant preferably adopts hydroxypropylated starch, and consumption is preferably 25%(weight).
Institute's synthetic washing powder according to the present invention can be country and saves a large amount of foreign exchanges, reduces cost, and has also solved the problem of existing washing powder Marine Pollution biology and disruption of ecological balance.Its washing effect is good, and every index has all reached country and quality standard promulgated by the ministries or commissions of the Central Government, and its detersive power is greater than set quota.Modified starch be water miscible starch and can with Mg
++, Ca
++Complexing can be with the hard water deliquescing so contain the washing powder of modified starch, and is easy to rinsing, have general starch the advantage that can not compare.
The invention will be further elaborated below in conjunction with specific embodiment.
