Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning, in particular to a cleaning composition and a preparation method thereof. BACKGROUND

[0002] Hair trimming tools such as electric shavers are a kind of equipment widely used in the field of personal care. With the improvement of personal care consciousness, the cleaning and sanitation of shavers as high-frequency use tools have gradually attracted attention. The current shaver cleaning products on the market are mainly divided into alcohol-based cleaning liquid and water-based cleaning liquid. The alcohol-based cleaning liquid takes ethanol or isopropyl alcohol as the main solvent and relies on its volatility to achieve rapid drying and bacteriostasis. However, the alcohol or isopropyl alcohol in the alcohol-based cleaning liquid has the properties of flammability and odor irritation, and high-concentration ethanol or isopropyl alcohol can damage the skin surface sebum film, and if it comes into contact with the skin during use, it can easily cause dryness and redness. In addition, it has a corrosive effect on the metal plating layer of the shaver head, and long-term use can cause the plating layer to fall off, resulting in a decrease in the sharpness of the shaver head. The water-based cleaning liquid takes water as the solvent, which can reduce the risk of flammability and reduce the skin irritation caused by ethanol or isopropyl alcohol. However, it usually uses anion (such as sodium dodecyl sulfate) or a single non-ionic surfactant, which has weak cleaning power and is difficult to clean the oil and debris in the gaps of the electric shaver head. In addition, there is no rust-proof design, and the shaver head is prone to rust and a decrease in sharpness. SUMMARY

[0003] The present application provides a cleaning composition and a preparation method thereof, which are used to solve the problem of poor cleaning effect and rust resistance of the existing cleaning liquid for hair trimming tools.

[0004] The present application discloses a cleaning composition, which comprises, in terms of mass fraction, 5-20 parts of a surfactant, 0.02-3 parts of a rust inhibitor, 0.01-0.5 parts of a chelating agent, 0.3-1.5 parts of a preservative, and 70-98 parts of a solvent. The surfactant is a non-ionic surfactant, which comprises a first surfactant and a second surfactant. The first surfactant comprises an alkyl glycoside surfactant, and the second surfactant comprises a sugar derivative surfactant. The solvent comprises water. It should be noted that the cleaning composition of the present application comprises double surfactants. The alkyl glycoside (APG) has good cleaning effect and strong decontamination ability, can penetrate the gaps of the shaver head to dissolve stubborn oil, and the sugar derivative surfactant can wrap debris and provide strong moisturizing and soothing anti-irritation. The two surfactants form a mild glycoside surfactant system, which can synergistically enhance the cleaning power. In addition, due to the non-ionic surfactant without soap base, the skin irritation is reduced, the compatibility with the skin is improved, and the irritation is reduced. The chelating agent can chelate metal ions such as calcium and magnesium, which is beneficial to avoid the reaction of metal ions with surfactants and affect the cleaning effect, and can assist in improving the stability of the rust inhibitor. The rust inhibitor can help reduce the rusting of the shaver head of the hair trimming tool.

[0005] In an implementation form of the application, the alkyl glycoside surfactant comprises C12-C20 alkyl glycoside, and the sugar derivative surfactant comprises maltodextrin glucoside. It should be noted that C12-C20 alkyl glycoside refers to an alkyl chain with a carbon number of 12 to 20, and the longer carbon chain has stronger lipophilicity, which can effectively dissolve and emulsify sebum and the like, and more effectively penetrate and deeply clean. Maltodextrin glucoside (MOG) contains an oligosaccharide group, which can wrap debris and provide strong moisturizing and soothing anti-irritation; the alkyl glycoside and the maltodextrin glucoside are compounded to form a mild glycoside surfactant system, which can synergistically enhance the cleaning power.

[0009] In an implementation form of the application, the rust inhibitor comprises a first rust inhibitor and a second rust inhibitor, the first rust inhibitor comprises a polybasic acid organic amine salt, and the second rust inhibitor comprises an organic carboxylic acid. It should be noted that the polybasic acid in the polybasic acid organic amine salt preferentially chelates calcium ions and magnesium ions in water through carboxyl sites, avoiding the interference of water scale on the rust prevention effect, and the organic amine salt can form a coordination bond with the surface of the tool bit metal (such as nickel alloy and stainless steel) through the amino group, thereby constructing a relatively thick and dense passivation layer to isolate oxygen and moisture and prevent oxidation and rust; the organic carboxylic acid can form a metal soap film layer; the organic carboxylic acid and the polybasic acid organic amine salt are compounded, which can enhance the adhesion and corrosion resistance of the rust prevention film and further improve the rust prevention performance.

[0038] The terms "first", "second", and the like in the context of the description of the components herein do not inherently imply any order, sequence, or technical

[0039] With the improvement of personal care awareness, hair trimmers such as razors are used frequently, and their cleanliness is gradually attracting attention. The current market razor cleaning products are mainly divided into two categories: alcohol-based cleaning liquid: with ethanol or isopropyl alcohol as the main solvent, relying on its volatility to achieve rapid drying and bacteriostasis. Its advantages are that the bacteriostatic effect is more durable, and the cleaning speed is fast, but the disadvantages are significant: alcohol or isopropyl alcohol has the nature of flammability and odor irritation; high-concentration ethanol or isopropyl alcohol can damage the skin surface sebum film, and if it comes into contact with the skin during use, it can easily cause dryness and redness; at the same time, it has a corrosive effect on the metal plating layer of the razor head, and long-term use can cause the plating layer to fall off, reducing the sharpness of the razor head. Water-based cleaning liquid: with anionic surfactants (such as sodium dodecyl sulfate; anionic surfactants have slightly stronger cleaning power but greater skin irritation) or single non-ionic surfactants (such as C12-14 alkyl glycoside; single non-ionic surfactants have lower skin irritation but insufficient cleaning power) as the main component, although they can reduce the risk of flammability and reduce the skin irritation caused by ethanol or isopropyl alcohol, but common shortcomings include: weak cleaning power, difficult to clean electric razor head gap grease debris, and no rust-proof design, razor head prone to rust and sharpness decline; single bacteriostatic component (such as phenoxyethanol) has limited effect, and long-term use can breed bacteria and mold; slow drying of residual liquid after cleaning, water marks are obvious, affecting the experience; most products have not optimized the foam characteristics, and excessive foam can easily block smart cleaning equipment, and foam residues remain in the razor head gap (requiring repeated rinsing multiple times). Therefore, the cleaning liquid of the hair trimmer in the prior art has the defects of incomplete cleaning, short bacteriostasis time, razor head corrosion, strong irritation, and excessive foam.

[0040] In view of this, the present application creatively proposes a cleaning composition and a preparation method thereof, which includes at least one of the following technical effects: synergistic cleaning force-mildness balance of double surface activity: alkyl glycoside (long carbon chain) is responsible for penetrating the gap of the cutter head to dissolve stubborn grease, and malt oligosaccharide glucoside (containing oligosaccharide group) is responsible for wrapping debris and providing moisturizing, both of which improve the cleaning force compared with single APG, and the skin irritation is reduced due to the non-soap-based degreasing effect of non-ionic surface activity; synergistic low-concentration broad-spectrum bacteriostasis: phenoxyethanol penetrates the bacterial cell membrane, and benzalkonium chloride destroys bacterial proteins, both of which cover gram-positive / negative bacteria and fungi, solving the "narrow-spectrum" problem of traditional single bacteriostatic agent; long-acting dual protection of chelation-rust prevention: the chelating agent first chelates calcium and magnesium ions in water (to prevent scale), and a multi-carboxylic acid (organic carboxylic acid) and organic amine complex rust prevention system is used, which not only inhibits metal electrochemical corrosion, but also avoids the interference of scale on the rust prevention effect by preferentially chelating calcium and magnesium ions in water through the carboxyl site of the multi-carboxylic acid; the organic amine forms a coordination bond with the surface of the cutter metal (such as nickel alloy and stainless steel) through the amino group, and a relatively thick and dense passivation layer is formed, which prolongs the rust prevention time compared with the use of a rust inhibitor alone; experience optimization of low-foaming and easy rinsing: the two non-ionic surfactants in the system are complexed, the amount of foam is low, and a defoaming agent of silicone type is introduced, which quickly inhibits the generation of excess foam in the presence of the surface active system, so that the product is almost impossible to foam, and the equipment is not affected. The present application can solve the problems of flammable irritation of existing alcohol-based formulations, incomplete cleaning of water-based systems, and lack of bacteriostatic and rust-proof functions, and achieve the comprehensive effects of mild and efficient cleaning, bacteriostasis, rust prevention, low foaming and low residue.
