Problems solved by technology

The soaping temperature of the soap powder products currently on the market is as high as 100°C. High temperature will cause many problems during the soaping process: sometimes it will cause the covalent bond between the reactive dye and the fabric to break, and there will often be more foam and consume less water. The amount of water is large, and a large amount of waste liquid will be produced during the soaping process, and the waste liquid is mostly rich in phosphorus, which will cause serious pollution to the environment. On the other hand, the soap powder produced has poor solubility and weak decontamination ability, which needs to be further improved

Abstract

The invention discloses laundry soap powder. The laundry soap powder is prepared from the following raw materials in parts by weight: 30-50 parts of vegetable oil fatty acid sodium salts, 10-15 partsof alpha-sulfo fatty acid methyl ester sodium salts, 20-35 parts of a nonionic surfactant, 2-5 parts of tea saponin, 1-2 parts of polyoxyethylene fatty acid, 0.3-0.5 part of sodium iminodisuccinate, 0.2-0.3 part of sodium citrate, 0.05-0.1 part of bamboo vinegar, 0.02-0.05 part of high-carbon alcohol fatty acid ester complexes and the like. According to the laundry soap powder, vegetable oil fattyacid sodium salts are adopted as a soap base material, multi-surfactants of an anionic surfactant and the nonionic surfactant are rationally adopted, a green chelating agent and other auxiliary agents are introduced, and ultrasonic treatment is combined with a high tower spray drying process to prepare the hollow granular laundry soap powder, so that the hollow granular laundry soap powder has high decontamination ability, low temperature instant dissolution, low foam, easy rinsing, easy degradation and environmental protection.

Description

technical field [0001] The invention relates to a laundry soap powder and a preparation method thereof, and belongs to the technical field of daily washing. Background technique [0002] The raw materials of fatty acid sodium in laundry soap powder products are derived from animal and vegetable oils, which are renewable resource raw materials. The laundry soap powder produced by using sodium fatty acid raw material to partially replace the petroleum-based surfactant in the laundry powder product is mild and non-irritating to the hands; it is easy to rinse, and compared with the general laundry powder product, rinsing can save about 30% of water. Therefore, laundry soap powder product belongs to the laundry product of green environmental protection type, is deeply liked by consumers in general. The soaping temperature of the soap powder products currently on the market is as high as 100°C. High temperature will cause many problems during the soaping process: sometimes it wil...
