Problems solved by technology

[0003] At present, the laundry detergents on the market basically contain a large amount of synthetic surfactants (such as alkylbenzene sulfonates, alkyl sulfates), chelating agents, preservatives, etc. These components will not only cause irritation to consumers' skin, but also It will bring environmental problems; the most effective way to remove protein stains in commercially available laundry detergents is to add protease, but protease is an allergen, which will cause allergies and irritation to the human body

preparation example Construction

[0028] The present invention also provides a method for preparing mild laundry detergent described in the above technical solution, comprising the following steps:

[0029] After mixing non-phosphorus chelating agent, non-amino acid anionic surfactant, nonionic surfactant, amino acid surfactant, remaining water, antiseptic additive and thickener, solid-liquid separation is carried out to obtain the mild laundry liquid.

Embodiment 1～9

[0034] In the preparation tank, add non-phosphorus chelating agent, non-amino acid anionic surfactant, non-ionic surfactant and amino acid surfactant in sequence, stir until completely dissolved; then add the remaining deionized water, and heat at 2°C / min After lowering the temperature from 55°C to below 30°C, add anti-corrosion additives and thickeners in sequence, stir until completely dissolved, filter, remove solid particles, and obtain mild laundry detergent, partially deionized water and remaining deionized The mass ratio of water is 2:3.

[0035] See Table 1 for the types and amounts (in % by mass) of the reagents used in Examples 1-9.

[0036] Take mild laundry detergent without amino acid surfactant component in the raw material as a comparative example, see Table 1 for the types and amounts (in mass percent) of the reagents used in the comparative example.

[0037] The kind and consumption of reagent in the embodiment 1~9 of table 1 and comparative example (by mass ...

Abstract

The invention provides a mild laundry detergent and a preparation method thereof, and belongs to the technical field of daily chemical products. The mild laundry detergent provided by the invention isprepared from the following components in percentage by mass: 1 to 25 percent of amino acid surfactant, 1 to 25 percent of multi-element surfactant, 1 to 10 percent of preservative aid, 0.1 to 5 percent of non-phosphorus chelating agent, 0.1 to 1 percent of thickening agent and the balance of water. According to the invention, the amino acid surfactant contains amide groups, has strong interfacial force and strong adsorption capacity to protein stains, and can efficiently remove the protein stains in clothes. No preservative or protease is added into the raw materials of the mild laundry detergent provided by the invention, so that the mild laundry detergent is mild and small in irritation to a human body and does not easily cause allergy.

Description

technical field [0001] The invention belongs to the technical field of daily chemical products, in particular to a mild laundry detergent and a preparation method thereof. Background technique [0002] Laundry liquid is a common product for people to wash and protect clothes in daily life. As people pay more attention to their own health and environmental protection, higher requirements are put forward for the safety, environmental protection and multi-functionality of laundry products, such as whether the raw materials Safe and gentle, whether there is any residue after washing, whether it has a bactericidal effect, etc. [0003] At present, the laundry detergents on the market basically contain a large amount of synthetic surfactants (such as alkylbenzene sulfonates, alkyl sulfates), chelating agents, preservatives, etc. These components will not only cause irritation to consumers' skin, but also It will bring environmental problems; and the most effective way to remove p...
