Description

Composition, method for producing same, toilet paper with same, and processing method using same

Technical Field

The present invention relates to the field of toilet hygiene, and more particularly to a deodorizing composition and a method for producing the same, and toilet paper using the same or containing the same, and a method for processing the same.

Background

How to solve the odor continuously generated in the toilet and improve the experience of people in using the toilet is always the subject of research in the field.

Toilet paper is a necessary consumable in toilets. Roll toilet paper can be placed in a household toilet and a hotel toilet in daily life, and small roll paper or a large roll paper with a disc can be placed in public places such as airports, high-speed rail stations, office buildings and the like because of the large number of people. These toilet papers for toilets are used for wiping clean and are soft in texture.

Therefore, the prior art solves the problem of toilet odor by adding a deodorizing agent to toilet paper and allowing the deodorizing agent in the toilet paper to absorb the odor.

Alternatively, some toilet papers have been provided with deodorizing agents on the paper core. The defect is that the paper core tube is covered by toilet paper, so that the deodorizing component is difficult to release; in addition, the common paper core tube material is a recycled fiber material with complex components, and the deodorant is added, so that the deodorizing effect is difficult to maintain.

Some toilet paper is added into the tail adhesive paste of the toilet paper roll, but the deodorizing effect cannot be sustained after the tail is torn off and used along with the unpacking of the consumer.

There are also some toilet papers in which the deodorizing agent is directly added to the toilet paper. However, in such toilet paper, the deodorant is in direct contact with the human skin, and is disliked by some consumers. Moreover, such deodorizing effect is consumed by toilet paper, and the amount of deodorizing agent used is large. In order to avoid that consumers do not like the deodorant to be in direct contact with the skin, and in order to fully contact the toilet paper added with the deodorant with the odor components, some toilet papers also add the deodorant in the middle of the multi-layer toilet paper. Thus, two layers in direct contact with the human body are free of deodorant.

However, these toilet papers easily absorb ammonia (urine odor) and trimethylamine (fishy smell) in the toilet, and even directly cause bacterial growth of the toilet paper, so that the toilet paper is not sanitary.

On the other hand, a large amount of organic acid is used in conventional deodorants. Although the organic acids have excellent deodorizing effect on the odor of the toilet, the organic acids can also corrode production and processing equipment, increase the acid corrosion risk and prevent the trouble of acid corrosion, and can only be produced by adopting processing equipment such as stainless steel, chrome plating and the like.

Detailed Description

In order to further describe the technical means and effects adopted by the present application to achieve the preset purpose, the following detailed description is given of the specific implementation, structure, characteristics and effects according to the present application with reference to the accompanying drawings and preferred embodiments:

in some embodiments, on the toilet paper of the present application, a composition for deodorizing (hereinafter referred to as deodorizing agent) may be applied. The deodorant is a composition composed of a plurality of compounds. In some embodiments, the odor eliminators of the present application are prepared by mixing a plurality of compounds. In some embodiments, the odor eliminators of the present application are prepared by uniformly mixing a plurality of compounds. In some embodiments, the mixing may be for 1-8 hours, or may be for 2-7 hours, or may be for 3-6 hours, or may be for 4-5 hours, or may be for 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 7.5, or 8 hours, or any range therebetween. In some embodiments, the mixing may be by adding the plurality of compounds to the solvent. In some embodiments, the solvent may be water, i.e., the odor-removing agent may be an aqueous solution. In some embodiments, the solvent may be ethanol, i.e., the odor eliminator may be an ethanol solution. In some embodiments, the solvent may be isopropyl alcohol, i.e., the odor eliminator may be an isopropyl alcohol solution. In some embodiments, the odor removing agent of the present application is added to the toilet paper of the present application, and after the solvent is removed by evaporation, evaporation or drying, the combined components (hereinafter referred to as odor removing components) other than the solvent, which are more difficult to be evaporated, evaporated or dried, remain on the toilet paper. The relative proportions between the deodorizing ingredients do not change too much, approaching or substantially identical to their relative proportions in the deodorizing agent, within a short time of the process of manufacturing the toilet paper. In some embodiments, the odor eliminating agent of the present application is, for example, an odor eliminating component of the odor eliminating agent of the present application, including citric acid and/or citrate, and other components such as alcohols, esters, or ethylenediamine tetraacetic acid and/or salts thereof.
