Description

Technical Field

[0001] The invention relates to the technical field of laundry detergents, in particular to a skin-mild decontamination laundry detergent and a preparation method thereof. Background Art

[0002] The cleanliness of clothing and textiles is closely related to people's living standards.

[0003] Laundry detergent is mild, easy to dissolve, and has low energy consumption. In the European, American, and Japanese markets, laundry detergent has accounted for 40-80% of the detergent market. The market share of laundry detergent in my country has maintained a rapid growth in recent years. As people's understanding of laundry detergent continues to deepen, their demand for laundry detergent is also increasing. In addition to requiring good detergency, they also require other functions, such as mildness without hurting hands, easy rinsing, softness, anti-static, color enhancement, and green environmental protection.

[0004] However, most traditional laundry detergent formulas use sulfate, alcohol ether carboxylate or sulfonate surfactants as active ingredients, alkanolamide 6501 as a thickener, alcohol ether and alcohol ether glycosides as main ingredients, which are prone to residual dioxane. 8-16 The use of quaternary ammonium salt cationic surfactants as bactericides makes laundry detergent highly irritating and easily leaves harmful substances on the laundry. Using it to wash clothes, especially for washing infant clothes and underwear, will affect people's health. At the same time, the formula contains some difficult-to-degrade ingredients that will pollute the environment. Summary of the invention

[0005] The object of the present invention is to provide a skin-mild decontamination laundry detergent and a preparation method thereof, so as to solve the problems existing in the prior art.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a skin-mild decontamination laundry detergent, which comprises, by weight, 10 to 15 parts of surfactant, 0.3 to 0.8 parts of inorganic salt, 1 to 3 parts of nano powder, 21 to 23 parts of extract, 0.4 to 1 part of cellulase, 0.5 to 2 parts of enzyme stabilizer, 0.4 to 1.5 parts of sodium hydroxide, and water added to 100 parts.

[0007] Furthermore, the surfactant is a cationic alkyl glucoside, an alkyl glucoside, and a fatty alcohol polyoxyethylene ether sodium sulfate in a mass ratio of 1:2-3:1-3.

[0008] Furthermore, the enzyme stabilizer is a mixture of one or more of borax, formate or propionate.

[0009] Furthermore, the alkyl glycoside is selected from methyl glycoside, ethyl glycoside, propyl glycoside, butyl glycoside, hexyl glycoside, octyl glycoside, decyl glycoside, dodecyl glycoside or tetradecyl glycoside.

[0010] Furthermore, the ionic alkyl glycoside is one of cationic methyl glycoside, cationic ethyl glycoside, cationic ethylene glycol glycoside, cationic propyl glycoside and cationic butyl glycoside.

[0011] Furthermore, the extract is a tropical red water lily extract, a vanilla extract, and a peony extract in a mass ratio of 1:1 to 3:1 to 3.

[0012] Furthermore, the nano powder has a mass ratio of silver powder to titanium dioxide of 2 to 3:1, and an average particle size of the silver powder and titanium dioxide of 5 to 100 nm.

[0013] Furthermore, the inorganic salt is sodium chloride or magnesium chloride.

[0014] Furthermore, the preparation method of the skin-mild decontamination laundry detergent is as follows:

[0015] (1) Add deionized water, surfactant, and extract into a mixing container in sequence and stir until completely dissolved;

[0016] (2) Add inorganic salt and nano powder and stir evenly;

[0017] (3) adding sodium hydroxide and stirring to dissolve;

[0018] (4) Add cellulase and enzyme stabilizer and stir thoroughly to obtain the skin-mild decontamination laundry detergent.

[0019] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0020] (1) The present invention uses tropical red water lily extract, orchid vanilla extract, and peony extract as natural effective active ingredients, replacing the difficult-to-degrade raw materials in common laundry detergents, while having both detergency and environmental friendliness, greatly improving the antibacterial property of the laundry detergent, and reducing the irritation of the laundry detergent, reducing irritation to the skin, solving various skin allergies, and thereby improving the mildness of the laundry detergent;

[0021] (2) The present invention uses a composite of cationic alkyl polyglycoside, alkyl polyglycoside, and sodium polyoxyethylene fatty alcohol ether sulfate as a surfactant, which can effectively reduce the surface tension of water and the wetting, penetration and emulsification properties, and has stable chemical properties. This combination can further improve the decontamination and cleaning ability of the laundry detergent, and can make the laundry detergent more gentle, more gentle to human skin, and has a good effect of moisturizing the skin, with less irritation;

[0022] (3) The cellulase in the present invention can tidy up fabric fibers, release deep stains, and repair damaged areas on the fiber surface, making the fibers smoother and flatter, and making the clothes brighter; and the addition of nano-sized titanium dioxide and silver can enhance the antibacterial property. Since the particle size is small enough, it can penetrate into the fiber during washing, and along with the external washing action, rub the fiber to remove the surface dirt, thereby enhancing the decontamination ability of the laundry detergent;

[0023] (4) The surfactants and detergents in this invention are compatible with each other and play a synergistic role, thereby enhancing the wetting, penetration, emulsification and dispersion capabilities of the system and having excellent washing performance. DETAILED DESCRIPTION
