Low-irritation liquid detergent and preparation method thereof

Abstract

The invention belongs to the technical field of liquid detergent preparation of daily chemical products and particularly relates to a low-irritation liquid detergent and a preparation method thereof. The liquid detergent disclosed by the invention is mainly prepared from the following components in percentage by mass: 6 to 10 percent of disodium monolauryl sulfosuccinate, 3 to 5 percent of lauryl alcohol phosphoric acid ester potassium, 5 to 7 percent of alcohol ether phosphate, 5 to 7 percent of cocoamidopropyl betaine, 12 to 16 percent of soap of fatty acid potassium, 2 to 4 percent of a metal complexing agent, 0.05 to 0.15 percent of a preservative, 0.3 to 0.8 percent of essence and 40 to 70 percent of water. The liquid detergent disclosed by the invention has the advantages of mutual matching of all the components, small irritation, high detergency, easiness in rinsing and no injury to skin.

Description

technical field [0001] The invention belongs to the technical field of configuration of laundry detergent in daily chemical products, and in particular relates to a low-irritant laundry detergent and a preparation method thereof. Background technique [0002] Laundry detergent is a commonly used cleaning agent in people's life, which mainly includes laundry soap, washing powder, and laundry detergent. The main component of laundry soap is sodium fatty acid, which has good decontamination effect, low foam and easy to rinse. The disadvantage is poor resistance to hard water, and Soap scum is easy to form in water with high hardness, and it cannot be used for machine washing. The main components of washing powder are surfactants, alkaline additives and fillers. The disadvantage is that too strong alkali is irritating to the skin and is not suitable for hand washing. Moreover, excessive alkaline additives lead to poor solubility of washing powder, and the plants are easy to hard...

[0002] Laundry detergent is a commonly used cleaning agent in people's life, which mainly includes laundry soap, washing powder, and laundry detergent. The main component of laundry soap is sodium fatty acid, which has good decontamination effect, low foam and easy to rinse. The disadvantage is poor resistance to hard water, and Soap scum is easy to form in water with high hardness, and it cannot be used for machine washing. The main components of washing powder are surfactants, alkaline additives and fillers. The disadvantage is that too strong alkali is irritating to the skin and is not suitable for hand washing. Moreover, excessive alkaline additives lead to poor solubility of washing powder, and the plants are easy to harden after washing, and laundry detergent has become the main research direction, but the disadvantage of laundry detergent is that it has poor biodegradability, is not easy to rinse, and is not conducive to saving energy. water

[0003] The Chinese patent with the notification number 102888313B discloses a laundry detergent for infants and young children. The ingredients are: fatty alcohol polyoxyethylene ether 4-8%; 70wt% sodium fatty acid methyl ester sulfonate 12-16%; 50wt% alkyl glycoside 4-8%; 25wt% of potassium soap 2-4%; 35wt% of cocamidopropyl betaine 8-10%; the balance is water, the main raw material used in the formula is biodegradable raw material , green and environmentally friendly; does not contain fluorescent whitening agents, phosphorus, dioxane, nonyl / octylphenol and nonyl / octylphenol polyoxyethylene ether, etc., ecological and environmentally friendly; has good calcium soap dispersion and mild and safe performance, but Most of the surfactants used in this invention are alkaline components, which are highly irritating to the skin
