Technical Field

The invention belongs to the technical field of corrosion prevention of daily chemical products, and particularly relates to a corrosion-preventing and sterilizing composition and a preparation method thereof.

Background

Daily chemical products are closely related to daily life of people, the use safety of the daily chemical products is concerned, and the safety and the non-toxicity of components of the daily chemical products are important as nursing products directly contacting with the epidermis of a human body. In order to prolong the quality guarantee time of the product and improve the sterilization and disinfection effects, some antiseptic and bactericidal components are often added into the product, the antiseptic and bactericidal components are mainly chemical synthetic reagents, and the addition amount, the physicochemical properties and the like of the antiseptic and bactericidal components can directly influence the quality of the nursing product.

Disclosure of Invention

In order to solve the problems, the invention provides the antiseptic and bactericidal composition and the preparation method thereof, the antiseptic and bactericidal composition has simple components and easy preparation method, and the obvious antiseptic, bactericidal and bactericidal effects can be achieved by adding a small amount of the antiseptic and bactericidal composition into a nursing product.

In order to achieve the purpose, the technical scheme of the invention is as follows:

the antiseptic bactericidal composition is characterized by comprising the following components:

octanoyl hydroxamic acid, chlorphenesin and hexanediol;

the components comprise, by mass, 15-30% of octanoyl hydroxamic acid, 8-16% of chlorphenesin and 55-75% of hexanediol.

Preferably, the components comprise, by mass, 18.3-25.2% of octanoyl hydroxamic acid, 10-12% of chlorphenesin and 62.8-71.7% of hexanediol.

Preferably, the components comprise 23% by mass of octanoyl hydroxamic acid, 10% by mass of chlorphenesin and 67% by mass of hexanediol.

Preferably, the antiseptic and bactericidal composition is used for antiseptic and bactericidal treatment of pseudomonas aeruginosa, candida albicans and aspergillus niger.

The preparation method of the antiseptic and bactericidal composition comprises the following steps:

(1) weighing octanoyl hydroxamic acid and hexanediol according to the mass percentage, heating, stirring and dissolving to obtain a mixed solution;

(2) weighing chlorphenesin according to the mass percentage, adding the chlorphenesin into the mixed solution shown in the step (1), stirring the mixture until the mixture is completely dissolved, and filtering the mixture to obtain the antiseptic and bactericidal composition.

Preferably, the heating temperature of the step (1) is 25-50 ℃.

Preferably, the heating temperature of the step (1) is 40 ℃.

The purity of the chlorphenesin is more than 99 percent, and the purity of the octanoyl hydroxamic acid is more than 99 percent.

The antiseptic and bactericidal composition is suitable for antiseptic and bactericidal of daily chemical products and care products, and can be applied to the technical fields of skin care liquid, bath foam, shampoo, hair lotion, skin cream, skin lotion, skin spray, wet tissues, mosquito and insect repellent liquid, air cleaning agents and the like.

The antiseptic bactericidal composition is applied to nursing products, and the added mass percentage is 0.5-1.2%.

The invention has the beneficial effects that:

(1) the invention provides an antiseptic and bactericidal composition and a preparation method thereof. The prepared composition is used in daily chemical products and nursing products, has obvious antiseptic and bactericidal effects on pseudomonas aeruginosa, candida albicans and aspergillus niger, and also has obvious bactericidal and bactericidal effects on other bacteria and moulds which are easy to breed in the daily chemical products and the nursing products, such as staphylococcus aureus, escherichia coli, pseudomonas aeruginosa and the like;

(2) the octanoyl hydroxamic acid and the chlorphenesin in the antiseptic and bactericidal composition are compounded with each other, so that the antiseptic and bactericidal composition has a synergistic effect, can keep the number of mould and bacteria in an applied product to be less than 10 cfu/g, and has an obvious bactericidal and bactericidal effect;

(3) the antiseptic and bactericidal composition is applied to products such as daily chemical nursing, can achieve remarkable bactericidal, bactericidal and antiseptic effects by adding trace amount, has no toxic or side effect on human bodies, and can prolong the shelf life of the products; the preparation method is simple, green and environment-friendly, and is easy to popularize and use.
