Abstract

The invention discloses a preparation method of phosphorus-free laundry powder, which comprises the following steps: putting sodium bicarbonate and hydroxymethyl cellulose into a mixer to uniformly mix; adding sodium dodecyl benzene sulfonate, sodium silicate and sodium perborate, and stirring for 10-30 minutes; adding a fatty acid, and 12 hours later, adding shikakai powder, essences and a fluorescent whitening agent, so that phosphorus-free laundry powder is obtained. The phosphorus-free laundry powder is prepare from the following materials in parts by weight: 3-8 parts of sodium bicarbonate, 1-5 parts of hydroxymethyl cellulose, 16-26 parts of sodium dodecyl benzene sulfonate, 1-6 parts of sodium silicate, 1-4 parts of sodium perborate, 5-10 parts of a fatty acid, 5-10 parts of shikakai powder, 0.1-2 parts of essences, and 0.05-0.5 part of a fluorescent whitening agent. The method disclosed by the invention is wide in raw material source, simple in process, less in production procedure, and simple in production equipment, and prepared laundry powder does not contain phosphorous, produces less foams, and has strong dirt removing power.

Description

technical field [0001] The invention belongs to the field of daily chemicals, and in particular relates to a preparation method of phosphorus-free washing powder. Background technique [0002] Laundry powder is a powder that is dissolved in water to make clothes easier to clean when washing clothes. The ingredients of washing powder generally mainly include surfactants, water softeners, alkali agents, bleaching agents, etc. When preparing washing powder, some additives and auxiliaries should be added to make the performance of washing powder more perfect. Common auxiliaries for washing powder are divided into two categories: inorganic salt and organic salt. According to whether the washing powder contains phosphorus, it is divided into phosphorus-containing washing powder and phosphorus-free washing powder. Sodium tripolyphosphate is mostly added to phosphorus-containing detergents to improve the cleaning effect of detergents. However, sodium tripolyphosphate has a strong...
