Description

Non-poisonous washing powder

The present invention relates to washing composition, particularly phosphate-free and aluminum-free household laundry powder.

In the synthetic detergent powder generally with phosphoric acid salt or poly-phosphate as washing assistant, owing to they bring environmental hazard to the eutrophication of water body.And phosphoric acid salt enters people's physical efficiency and the intravital solubility calcium effect of people by skin, generates insoluble calcium phosphate and excretes, and causes calcium deficiency in the body.Diseases such as recently state such as Japan releases without phosphorus or limit phosphorus washing powder, adopts aluminiferous salt to make washing assistant, but aluminum ion enters and might bring out senile dementia in the body, and kidney function damage and bone lattice are softening.Therefore studying a kind of nontoxic washing assistant making non-poisonous washing powder is an important problem.NL7511-337 has announced a kind of without phosphorus prescription that contains calcium carbonate superfine powder and yellow soda ash and sodium bicarbonate and/or concentrated crystal soda, but does not relate to toxicity problem.J51030-206 mentions the washing composition made from concentrated crystal soda and phosphorated nonionic, cats product, but still has certain toxicity.

The objective of the invention is to seek a kind of non-poisonous washing powder of phosphate-free and aluminum-free.

Studies show that concentrated crystal soda is effective washing assistant in washing composition, alkalescence a little less than, character is gentle soft.Concentrated crystal soda is made up of the nontoxic yellow soda ash of equimolecular quantity and sodium bicarbonate.Available 106 parts of yellow soda ash and 84 parts of sodium bicarbonates (or excessive 5%), be dissolved in respectively below 60 ℃ in the clear water, make into saturated solution, while hot both are mixed, stir evenly, it is complete to crystallization to slowly cool to 36 ℃ ± 5 ℃ insulation ageings, the leaching crystal dries, and dries in room temperature, or 65 ℃ ± 5 ℃ warm air dryings, get the white needles finished product.Also can be yellow soda ash and sodium bicarbonate with 106: weight ratio 84(or excessive 5%) mixes the back and joins in other component of washing powder by formula rate, by certain technological process, makes non-poisonous washing powder of the present invention.The scope of prescription of the present invention (weight percentage) is:

Surface-active substance: 30～16%

Yellow soda ash: 12～40%

Sodium bicarbonate: 10～32%

Anhydrous sodium sulphate: 42～0%

Water glass (40Be '): 5～10%

Xylo-Mucine: 1～2%

Surface-active substance of the present invention is: anion surfactant: Sodium dodecylbenzene sulfonate or sodium lauryl sulphate.Nonionogenic tenside is a coconut acid diethanolamide.Its typical prescription is (weight percentage):

Sodium dodecylbenzene sulfonate 10%

Sodium lauryl sulphate 5%

Coconut acid diethanolamide 5%

Yellow soda ash 20%

Sodium bicarbonate 17%

Water glass (40Be ') 10%

Xylo-Mucine 1%

Anhydrous sodium sulphate 25%

Water 7%

Technical process of the present invention is:

The washing powder that the present invention makes send daily chemical product quality examination junction centre in Jiangxi Province's to detect, and its result is as shown in table 1.As shown in Table 1, not phosphorous hydrochlorate of washing powder of the present invention and aluminium salt, but decontamination index, pH value, every index such as apparent density all reaches the standard-required of China National Light Industrial Products Department.

Embodiment:

Be example with 30 kilograms of raw materials below, its production process is described: the solid material of bulk or conglomeration is pulverized, cross 60 mesh sieves, weighing in the following order: 7.5 kilograms of anhydrous sodium sulphate, 1.5 kilogram sodium lauryl sulphate, 5.1 kilogram sodium bicarbonate and 6.0 kilograms of yellow soda ash are put into the mixing machine of 0.75 kilowatt of 60 rev/mins of speed, sealing was stirred 3 minutes.Take by weighing 0.3 kilogram of Xylo-Mucine, tear up, join in 1.5 kilograms of coconut acid diethanolamides, stir moltenly, add 3.0 kilograms of 40Be ' water glass, stir, add 0.1 kilogram of clear water, fully stir, slowly join in the mixing machine equably, need not seal, start was stirred about 25 minutes, till the even group of rising, with 90 ° of mixing machine hopper upsets, 20 mesh sieves are used earlier in discharging, sieve with 80 mesh sieves then, get the sieve material between 20 order to 80 orders, move into kiln, pave into 20 mm thick, naturally dry about 48 hours, or with 65 ℃ of warm air dryings 24 hours, during need stir take off even, to moisture≤15%, pack is sealed.

In sum, washing powder of the present invention is not phosphorous, and not containing aluminium is a kind of non-poisonous washing powder, and formulation cost of the present invention is cheap, and washing effect is good, and is harmless without any pollution, and technical process is simple, is particularly suitable for vast township and village enterprises and produces.
