OXYGEN GENERATING DIAPER AND SANITARY NAPKIN WITH STERILIZING FUNCTION, AND OXYGEN GENERATING COMPOSITION THEREOF}

The present invention relates to a functional diaper and sanitary napkin, and more particularly, to a functional diaper and sanitary napkin capable of supplying oxygen to the skin in contact with the diaper and the sanitary napkin by adding a substance that generates oxygen to the diaper and the sanitary napkin.
The use of the diaper and sanitary napkin has the advantage of improving skin health by generating oxygen to improve breathability and preventing skin sores, inflammation and odors. In addition, the cleanliness of the skin may be improved due to the antibacterial and disinfecting effects of hydrogen peroxide generated when oxygen is generated by the oxygen generator.

Diapers are hygiene products that absorb and store secretions, such as urine and dung, which are discharged by newborns and are discarded after discharge. Therefore, in the diaper, materials such as nonwoven fabric and absorbent polymer are used as a material for absorbing moisture and protecting the absorbed material from leaking to the outside.

Sanitary napkins are hygiene products that absorb and store discharges such as menstrual blood discharged during menstruation and are disposed of after discharge.

However, the use of diapers or sanitary napkins increases the humidity in the area where the diaper or sanitary napkin is in contact with the skin. Due to the increased humidity and temperature, bacterial microorganisms such as Staphylococcus aureus grow around the secretions. Growing microorganisms are metabolites that emit various odors and irritate the skin. This irritated skin can cause inflammation, fungus or sores.

The present invention seeks to provide a new functional diaper and sanitary napkin in which an oxygen generating material is added to the diaper and sanitary napkin to improve these problems. In addition, the oxygen generating agent applied to diapers and sanitary napkins can be applied to various household products such as disposable sanitary napkins, towels (naphkines, tissues) to give oxygen generating function, which can give a good effect of improving hygiene and cleanliness around the skin used. have.

The present invention generates oxygen in the diaper and sanitary napkin, that is, oxygen is generated when the excrement such as urine is added by adding an oxygen generator, so that the lack of breathability due to the use of the diaper and sanitary napkin and inflammation, mold or sores on the skin It is an object of the present invention to solve the phenomenon.
In the present invention, to improve the performance of the oxygen generator by adding a catalyst and a material for adjusting the pH to the oxygen generator composition.

Hereinafter, the problem solving means of the present invention will be described in more detail.

The functional diaper and sanitary napkin of the present invention, as shown in the cross-sectional view of FIG. 1, is characterized by being composed of a nonwoven fabric 1, an absorber layer 2 disposed therein, and an oxygen generator layer 3 comprising an oxygen generator composition. do. At this time, the oxygen generator layer is a layer composed of a material capable of generating oxygen by reacting with the moisture contained in the secretion or excretion from the body.

In general, oxygen generating materials can be found in the literature, such as sodium peroxide, potassium peroxide, potassium peroxide, perchlorate, calcium peroxide, sodium percarbonate. For example, in the case of sodium peroxide,

In the case of potassium peroxide,

Oxygen is generated by the reaction of Formula 1 and Formula 2.

However, sodium peroxide, potassium peroxide, potassium peroxide, perchlorate, etc. are strongly alkaline or hygroscopic, so when applied to or attached to diapers and sanitary napkins, they may deteriorate or decompose during storage (distribution period). It is very difficult to use as an oxygen generator for use. Therefore, in the present invention, a substance selected from calcium peroxide, magnesium peroxide, sodium percarbonate, potassium percarbonate, and the like is used as an oxygen generator. However, these oxygen-generating substances also become alkaline when they come together with moisture, which can irritate the skin. To improve this, citric acid, potassium monophosphate, glutamic acid, ascorbic acid, salicylic acid, tartaric acid, and glycolic acid Soluble in water such as glycolic acid, lactic acid, sodium monophosphate, cysteine hydrochloride, 6-aminocaproic acid, and glycyrrhizic acid A material selected from a solid acid having a melting point of 50 ° C. or more was used as a neutralizing agent or a buffering agent.

As described above, the oxygen generator mixed with the oxygen generating component, the neutralizing agent, and the buffer agent generates oxygen when reacted with moisture, but the oxygen generation rate is slow and not sufficient. To improve this, components such as manganese dioxide (MnO 2), silver (Ag), potassium iodide (KI), catalase, and yeast can be used as catalysts.
Among the catalysts, manganese dioxide, silver, potassium iodide, and catalase are black in color or appear red after the reaction, making them aesthetically inconvenient to use and relatively expensive. Yeast can cause problems with its unique odor and fairness (stable at heating) during storage.

The rate of oxygen evolution was increased by using a catalyst selected from ferrous compounds such as ferric sulfate.

Such a catalyst is preferably used in a ratio of 0.001 g to 0.05 g based on 1 g of the oxygen generator used. Oxygen generator composition prepared by the above composition is installed in the diaper and sanitary napkin and generates oxygen by reacting with water discharge such as urine, dung, menstrual blood.

Oxygen generator composition is calcium peroxide, magnesium peroxide, sodium percarbonate or potassium percarbonate among the components are alkaline with the generation of oxygen in the aqueous solution by the reaction as shown in the reaction scheme (Formula 3, Formula 4, Formula 5). However, the neutralization reaction occurs at the same time as the oxygen is generated by the neutralizing agent or the buffer agent contained in the oxygen generating composition, the pH of the reaction solution is neutralized to around 6-8.

The neutralizing agent or buffering agent (buffering agent) is preferably used in the range of 0.1g to 4g with respect to 1g of oxygen generator, more preferably used in the range of 0.5g to 2.5g with respect to 1g of oxygen generator It is preferable.

In the oxygen generator composition prepared as described above, the peroxide and the percarbonate product in the solid powder state are mixed with the acidic buffering agent in the solid powder state, and are more sensitive to moisture. Thus, contact with wet air during storage or storage at high temperatures can lead to loss of function as an oxygen generator composition. To solve this, stabilizers were added to improve the storage stability. That is, alumina (Al 2 O 3), silicate (SiO 2), zeolite, molecular sieve, sodium sulfate, calcium sulfate, magnesium sulfate, calcium chloride, etc. Powders of the same inorganic materials (alkali or alkaline earth metal sulfates, carbonates, oxides or chlorides) were added in an amount ranging from 0.1 to 3.0 g per 1 g of oxygen generating agent to improve storage stability.
