Abstract

The present invention belongs to a composition of a washing agent using alkali soap as a base material, and a making method. In the method, soap powder is composed of animal and vegetable oil neat soap, a calcium ion dispersant and other auxiliary agents. The composition is made by a novel agglomeration shaping technology. The composition has the advantages of strong washing power in both hard water and cold water, favorable biodegradation performance, no pollution, no stimulation to human skin, simple production technology and high product quality.

Description

Soap powder is formed and manufacture method

The present invention relates to a kind of is the detergent composition and the preparation method of base-material with the alkali soap.

As everyone knows, common cloth-washing detergent mainly contains two big classes: soap and washing powder.The raw material of soap is easy to get, and biological degradability is good, and soil removability is preferably arranged in soft water and hot water, but soil removability significantly descends in hard water and in the cold water.Though washing powder all has stronger washability under various conditions, its phosphorus content height pollutes environment, has influence on vegeto-animal growth and human health.Although researching and developing at present with the phosphorus in the various auxiliary agents replacement washing powder, effect still can not be satisfactory.The one, can not substitute phosphorus fully, the 2nd, cause new pollution again, initiate auxiliary agent often has pungency to human body skin.

In order to overcome soap and washing powder shortcoming in use, and keep their advantages separately, the interest that the development of a kind of marginal New-type detergent--soap powder and exploitation cause people.Yet the composition and the manufacture method of the soap powder that just existing document is reported can't reach above-mentioned ideal purpose.JP5558300A for example ₂The composition of the soap powder of being introduced is the lipid acid of C≤14, the mixture of the water-soluble salt of the unsaturated fatty acids of the saturated fatty acid of C 〉=14 and C 〉=14 (45%), tripoly phosphate sodium STPP (10%), water glass (9%) and Sodium peroxoborate (25%).Not only still have the phosphorus of high level in this composition, soil removability is not strong yet in hard water and cold water simultaneously, in production technique, adopted besides spraying drying (have in addition bibliographical information with in fluidised bed drying or the dry type and moulding), these drying meanss are not easy to guarantee the quality of product.And for example US4812252 has introduced in lipid acid and soap and has added ether carboxylate, as 3-(2-oxyethyl group) Sodium Propionate, in order to replace coconut soap one class pore forming material, its effect just improves the lathering property of soap base washing composition, can not improve its soil removability in hard water significantly equally.

The purpose of this invention is to provide under various conditions a kind ofly, being included in all has strong washability in hard water and the cold water, and biodegradability is good simultaneously, soap powder product free from environmental pollution and brand-new, without heat drying, guarantee the high-quality manufacture method of product.

Soap powder of the present invention is made up of soap base, calcium ion dispersion agent and other collaborative auxiliary agent.Wherein soap base is animal oil soap (as ox, sheep, lard soap or their mixing oil soap) and vegetable oil soap (as soybean, peanut, rape seed oil soap or their mixing oil soap).The calcium ion dispersion agent is a dodecyl alcohol sodium sulfate, or α-sulfonated stearic acid methyl esters sodium, or α-Huang Huazhifangsuanjiazhi sodium, or alkylphenol polyoxyethylene, or aliphatic acid polyethenoxy ether, or selects wherein two kinds simultaneously for use, or three kinds, or use four kinds simultaneously.Collaborative auxiliary agent has: the hydration crystallization promoting agent, and as Na ₂CO, Na ₂SiO ₃, anhydrous Na ₂SO ₄Deng; The collaborative auxiliary agent of calcium ion dispersion agent is as Xylo-Mucine, sodium cellulose glycolate etc.; Washing assistant, as NaOH, KOH, Ca (OH) ₂Deng; Also have white dyes and odor additive, as geraniol.

The proportioning of various components in the soap powder of the present invention (weight %) is:

Animal oil soap 21～28%

Vegetable oil soap 9～12%

Calcium ion dispersion agent 1.5～7%

The collaborative auxiliary agent 0.5～2% of calcium ion dispersion agent

Washing assistant (34%) 2～5%

The hydration crystallization promoting agent

Na ₂CO ₃ 15～30％

Na ₂SiO ₃(30％) 2～10％

Na ₂SO ₄(anhydrous) 15～35%

White dyes 0.1～0.5%

Water 13～18%

Odor additive a little

The manufacture method of soap powder of the present invention adopts brand-new the attached polymer molding technology, and specific operation process is earlier with Na ₂SiO ₃(30%) drops in the kneading mixing machine, drop into the animal and vegetable oil soap subsequently, thorough mixing is even, add washing assistant solution (34%), add the calcium ion dispersion agent again and stir, the collaborative auxiliary agent (even with aquation) that then adds the calcium ion dispersion agent is not stopping successively to add hydration crystallization promoting agent Na under the stirring ₂CO ₃And Na ₂SO ₄(anhydrous) adds white dyes at last.The said mixture material is constantly mixed and dispersion in mixing machine, make its uniform distribution, finish physical and chemical processes such as hydration crystallization and adhesive aggregation simultaneously and form agglomerate.Take out the agglomerate that generates in the mixing machine and drop into granulation in the tablets press, obtain granularity, in aroma device, add odor additive at last, obtain the soap powder product after evenly at 20～60 purpose particles.

The advantage that present method compared with prior art has is: body material is identical with soap, is the animal and vegetable oil soap, and raw material is easy to get, and biodegradability is good, and is not phosphorous, thus free from environmental pollution, do not stimulate human body skin yet, safe in utilization.Owing to added the calcium ion dispersion agent, generate calcium soap precipitates when having avoided in hard water washing and washability is reduced.Again owing to adopted brand-new the attached polymer molding technology in the manufacturing processed, needn't heat drying, component mixes fully, and it is very even to distribute, thereby quality product improves greatly, and (being included in hard water and the cold water) under various conditions all has stronger washability.Production technique of the present invention is simple, and save energy reduces cost.
