The present invention relates to a disposable absorbent product containing a deodorant component, and more specifically, a component of a conventional disposable absorbent product composed of a liquid permeable top sheet, a liquid impermeable back sheet, a fluffy pulp, a super absorbent resin, and a coagulation band. The purpose of the present invention is to provide a disposable absorbent product having excellent usability and skin stability by containing a deodorant component in a heavy cuff.

In general, the disposable absorbent product refers to a product that absorbs body fluids excreted by physiological action, that is, a product that absorbs urine and stool secretions, menstrual and vaginal secretions, and more specifically, disposable diapers used by infants or adults ( Diaper, Sanitary napkin or Panty liner.

The performance of the above-mentioned disposable absorbent products has been developed with the development of super absorbent polymers, focusing primarily on the functional aspect, that is, the absorption rate and the amount of the body fluid secreted by physiological action. In the use of disposable absorbent products, there should be no side effects on the site of use of the product, and a product with excellent performance in terms of usability that effectively prevents unpleasant odors associated with the excretion of body fluid is required. Secretions are absorbed as soon as they are secreted and their absorbency has also been reached.

However, in terms of usability to properly remove unpleasant odors such as ammonia when excretion is excreted, it is impossible to effectively remove toxic gases such as ammonia generated by urine decomposed by stool or skin residing bacteria on the skin. There are many problems such as diaper rash, such as dermatitis by stimulating.

In order to solve the shortcomings of the prior art, Korean Patent Application Publication No. 90-5652 discloses disposable absorbent by adding a baby powder whose main component is talc to the groove of the elastic yarn on the outside of the curing band among the components of a conventional disposable absorbent product. It is mentioned that it solves diaper rash, which is the biggest problem when using the product, but the baby powder is added to the elastic chamber attached directly to the liquid impermeable back sheet, so it is in direct contact with the discomfort such as ammonia existing between the disposable absorbent product and the skin when worn. Since there was little opportunity to do so, it was not possible to properly remove the generated unpleasant odors and prevented diaper rash such as skin rash.

In addition, even if a deodorant is added to remove unpleasant odors and prevent skin rash, it is added to a liquid permeable top sheet, tissue down pulp, and so on. It also lost its function and could not be an effective way.

Therefore, there has been a great demand for the emergence of disposable absorbent products having excellent performance without removing unpleasant odors associated with body fluid excretion and without diaper rash such as dermatitis.

Accordingly, the present invention is a component of a conventional disposable absorbent article composed of a liquid permeable top sheet (2), a liquid impermeable back sheet (1), fluffy pulp, and a super absorbent polymer (3) and a coagulation band (7) (8). The purpose of the present invention is to provide a disposable absorbent product having excellent usability and excellent skin stability by containing deodorizing and deodorizing components in the solidified band.

Hereinafter, the present invention will be described in detail.

The present invention is 0.1-10% by weight of the total weight of disposable absorbent products alone or by mixing porous materials such as activated carbon, talc, bioceramic, bauxite silica and mica, which are deodorizing components, in the curable band among the components of a conventional disposable absorbent product. By adding a% to remove toxic gases such as ammonia accompanying body fluids to provide excellent disposable absorbent products with excellent usability and no skin rash.

That is, when the deodorizing active ingredient is added to the coagulation band, when the disposable absorbent product is worn, the walls 7, 7 ′ of the components of the coagulation band stand vertically with the skin and the contact surfaces 8, 8 ′ are skin. Since it is in close contact with the toxic gas such as ammonia present in the space between the skin and the liquid permeable top sheet of the disposable absorbent product can be effectively deodorizing function.

In addition, the body fluid to be excreted is first absorbed by the pulp and super absorbent resin located in the lower portion of the liquid permeable top sheet to block only part of the coagulation band of drift, so that the effective deodorizing active ingredient by moisture, etc. as in the prior art This is not lost.

When the added amount of the deodorizing active ingredient is less than 0.1% by weight of the total weight of the disposable absorbent product, the unpleasant odor associated with body fluid excretion cannot be properly deodorized, and when the weight of the absorbent product is more than 10% by weight of the total weight of the absorbent product, the solidified band has a solid tendency. Because of this, the skin is in contact with the physical irritation is another cause of the skin rash.

Hereinafter, the present invention will be described in detail with reference to Examples.

[Example 1-2 and Comparative Example 1-3]

Example 1-2 and Comparative Example 1-4 examined the usability and skin rash incidence according to the content of the deodorizing component of the components of the disposable absorbent product (total weight: 50g).

Example 1 is a disposable absorbent on the contact surface (8) (8 ') portion of a coagulation band of a typical disposable absorbent product component consisting of a liquid permeable topsheet, downy pulp, superabsorbent resin, a liquid impermeable backsheet, and a coagulation band. 0.5g of activated carbon, which is 1% by weight of the total weight of the product, was added, and Example 2 was a product produced by adding 0.5g of activated carbon to the wall 7 (7 ') portion of the solidified band.

In Comparative Example 1, 0.5 g of activated carbon was added to the grooves of the elastic chambers 11 and 11 'positioned at the outer portion of the curing band to the conventional disposable absorbent product composition prepared in the same manner as in Example 1, and Comparative Example 2 0.5g of activated carbon was added to the liquid permeable top sheet 2 instead of the groove of the elastic chamber of Comparative Example 1, and in Comparative Example 3, 0.5g of activated carbon was added to the fluffy pulp 3.

Using Example 1-2 and Comparative Example 1-3 prepared by the above method for 100 infants 3-6 months of age for 3 months to evaluate the usability and skin rash incidence according to the determination of the following symptoms Table 1 , Table 2 is shown.

The unpleasant recognition rate in terms of usability is the ratio of the unpleasant odor when the diaper is replaced or severely felt among the 100 items.

[Judgment of symptoms]

Usability

[+ +]: There is no discomfort when changing diapers.

[+]: Difficult to recognize unpleasant when changing diapers.

[±]: When changing diaper, you can recognize unpleasant odor.

[-]: When changing diapers, the discomfort is severe.

TABLE 1

[Judgment of symptoms]

Skin Rash

[++]: No diaper rash.

[+]: Red spots.

[±]: Red spots are strong and have erosion.

[-]: Red spots are strong and erosion is wide spread.

TABLE 2

As can be seen in Table 1, in Examples 1 and 2, the unpleasant recognition rate felt when replacing disposable absorbent products is only 4% and 1%, but in Comparative Examples 1-3, 86%, 87%, and 96% are Each could recognize a nuisance. Therefore, when activated carbon was added to the coagulation band, the best deodorizing effect was obtained.

In addition, it can be seen in Table 2 that the skin rash incidence is also excellent in Example 1-2. In summary, Table 1 and Table 2 show that activated carbon added to the coagulation band effectively deodorizes the toxic gases involved in the excretion of body fluids, thereby suppressing skin rashes.

Example 3-5 and Comparative Example 4-5

Examples 3-5 and Comparative Examples 4-5 relate to the amount of deodorant ingredient added, the purpose of which is to select an appropriate amount in terms of usability and skin safety. In Examples 3-5 and Comparative Examples 4-5, the activated carbon was added to the coagulation band in common to prepare a disposable absorbent product (total weight 50 g).

Example 3 is 0.1% by weight of the total weight of the absorbent product, Example 4 is 1% by weight, Example 5 is 10% by weight, Comparative Example 3 is 0.09% by weight, Comparative Example 5 is 11% by weight when the elastic band attached Prepared by addition. Example 3-5 and Comparative Example 4-5 were carried out on 100 infants aged 3-6 months, according to the criteria for usability and skin rash symptoms of Examples 1-2 and Comparative Examples 1-3. And Table 4 are shown.

[Table 3] Usability

[Table 4] Skin Rash

As can be seen in Table 3 above, in terms of usability, if the content of the deodorizing active ingredient is 0.1% by weight or more of the total weight of the absorbent product, it is excellent in usability by effectively removing the unpleasant odor generated during body fluid excretion, and less than 0.1% by weight. It is weak enough to properly deodorize the odor.

In addition, in terms of skin rash occurrence in Table 4, if the content of the deodorizing active ingredient is less than 0.1% by weight of the total weight of the absorbent product, the skin rash incidence rate is high because it does not properly deodorize odors harmful to the skin. Its excellent deodorizing effect is excellent in usability, so that the excessive amount of activated carbon as a solid causes physical irritation, resulting in high skin rash incidence.

Therefore, excellent usability and excellent skin stability are Examples 3-5, and the active ingredient of the deodorant is in the range of 0.1 to 10% by weight of the total weight of the absorbent product.

As can be seen from Table 5, Example 6-11 has an excellent deodorization function of less than 5% of the unpleasant recognition rate when replacing a disposable absorbent product, and the occurrence rate of skin rash caused by the disposable absorbent product when worn is also 6% or less. It is a disposable absorbent product composition.

As seen above, the disposable absorbent product according to the present invention has a superior odor deodorizing function such as ammonia generated when bodily fluid is secreted than a conventional disposable absorbent product, and the occurrence rate of skin rash due to skin irritation of such odors is greatly improved. Disposable absorbent products with superior functions compared to disposable absorbent products are possible.

Example 6-11

The disposable absorbent article used in Example 6-11 was prepared in the same manner as in Example 1 except for the added deodorizing active ingredient and the results are shown in Table 5.
