The present invention relates to a disposable absorbent article, and more particularly, to a disposable absorbent article comprising a liquid-permeable top sheet, a liquid-impermeable back sheet, a fluff pulp, To a disposable absorbent article composition containing Eucalyptus oil.

Herein, the disposable absorbent product refers to a product that absorbs body fluids excreted by various physiological functions, that is, a product that absorbs secretions of urine and feces, menstrual fluid, and vaginal secretion. Specifically, it refers to a disposable diaper, a sanitary napkin, or a pantyliner used by an infant or an adult. The term disposable refers to a product that is discarded after a single use, composted, or disposed of in an environmentally compatible manner. (I. E., The product is not washed or otherwise restored or reused as a disposable product). The term diaper refers to a garment that is commonly worn by infants and incontinent adults by pulling and securing them between the legs near the waist of the wearer. The term incontinence products refers to pads, undergarments, inserts for inhalation products, bed pads, etc., regardless of whether the wearer is an adult or other impaired person. The term sanitary napkin refers to a product that a woman wears in the vulva, which is intended to absorb and accommodate various secretions (blood, menses, and urine). The term panty liner refers generally to a less bulky absorbent product that is worn by women during the menstrual cycle.

The performance of the disposable absorbent product has been developed by development of a superabsorbent polymer or the like primarily focusing on the absorption rate and the amount of absorbed body fluids separated by physiological action. In addition, the performance that should be followed by absorbency is the development of a system that effectively avoids the unpleasant smell that accompanies the excretion of body fluids when there is no side effect of the product use site in using the product.

Conventional absorbent products are characterized in that urine elements are decomposed by feces or bacteria (urease: Urease) present in the skin to generate ammonia, and when used by skin stimulation by ammonia, diaper rash, red spot and skin inflammation And also discomfort caused by urine and body fluids secretion can not be appropriately deodorized, which causes discomfort to the user.

In order to solve the problems described above, Korean Patent Laid-Open Nos. 86-8743 and 86-8744 disclose that diaper rash is prevented by using inorganic acid or by controlling PH by adding acid functional moieties, Can not be considered effective. In addition, Korean Patent Application No. 90-6465, which is a far-infrared radiation material, uses bio ceramics to prevent skin inflammation and rash caused by ammonia generation inhibition and deodorization effect. However, It was not effective in eliminating the accompanying instant displeasure or preventing skin rash and skin inflammation. As another example, there is a treatment with a bactericide synthesized by a chemical synthesis method. However, since a considerable amount of a synthetic bactericide is required to remove the bacterial skin bacteria, there is another problem caused by the irritation of the antibacterial agent added to prevent skin rash And the sterilizing agent itself can not act as a deodorant.

Disclosure of the Invention In order to solve these problems, the present invention provides a disposable absorbent article comprising a liquid-permeable top sheet, a fleece pulp, and a liquid impermeable back sheet, wherein Eucalyptus oil is added to the skin to remove urine or fecal matter It is an object of the present invention to provide a disposable absorbent product which can inhibit the production of ammonia, which is a seafood product, and prevent skin irritation and skin rashes, and provide a deodorizing effect and a refreshing sensation when worn.

The present invention provides a disposable absorbent article characterized by containing Eucalyptus oil in all or part of the disposable absorbent article comprising a liquid permeable topsheet, a fleece pulp, a liquid impermeable backsheet and a superabsorbent resin.

The present invention also relates to a process for the manufacture of disposable absorbent articles characterized by the addition of Eucalyptus oil to a liquid permeable topsheet, a tissue or fleece pulp, or a disposable diaper, .

The present invention also relates to a process for the manufacture of disposable absorbent articles characterized by the addition of Eucalyptus oil to a liquid permeable topsheet, a tissue or fleece pulp, or a disposable diaper, .

In the disposable absorbent product of the present invention, the content of Eucalyptus oil is preferably 0.1 to 20% by weight based on the total weight of the disposable absorbent article. Disposable diapers produced by using less than 0.1% by weight of Eucalyptus oil with respect to the total weight of disposable absorbent products can not properly absorb unpleasant odors such as ammonia generated during the secretion of body fluids. Disposable absorbent products produced by using Eucalyptus oil in an amount of 20% by weight or more based on the total weight of the disposable absorbent product composition may have a relatively low absorption capacity because the amount of the fluff pulp or superabsorbent resin is reduced.

Eucalyptus oil used in the present invention is an essential oil obtained by steam distillation of leaves of Eucalyptus globulus Labillardiere or other related plants (cloves and Myrtaceae), and is a colorless or pale yellow transparent liquid. It has a refreshing taste with a peculiar direction and irritating taste. 0.91-0.93. In addition to cineol (eucalyptol, about 70%), P-cymene, cuminal, and pinene are contained. The minor components include lower fatty aldehydes, Phellandrene and Sesquiterpene. Anti-inflammatory, antiseptic, antiseptic, antiseptic, and fragrance. In the present invention, Eucalyptus oil prepared by spray drying was applied. In the present invention, the liquid-permeable top sheet is a known one for use in conventional disposable absorbent products, and the liquid-permeable top sheet most commonly used is a nonwoven fabric or a PE film. The fluff pulp is a hydrophilic absorbent material which is made by processing wood pulp and is made of fluff and is used for absorbing the secretion. It is known to be used in ordinary disposable absorbent articles. Generally used are non-breathable waterproof film, breathable waterproof film, There may also be used biodegradable waterproof films and laminated nonwoven fabrics with such liquid impervious backsheet.

There are various methods for applying the Eucalyptus oil used in the present invention to the absorbent product. Typical examples of such methods include

(1) A method of containing a liquid permeable top sheet

(2) Method for incorporation into fleece pulp

③ How to incorporate into the barrier cuff

④ Method of incorporation into superabsorbent resin tissue

And (5) a method of incorporating the disposable absorbent article at the time of manufacturing.

Eucalyptus oil is added to the conventional disposable absorbent product composition to impart antibacterial and antiseptic effects as well as a directional and cooling sensation to the product. It is possible to deodorize and deodorize the unpleasant odor that may be caused when using the bodily fluid, and to suppress the generation of ammonia, which is a decomposition product of the urea in the body fluid secretion, thereby preventing skin disease and skin rash.

Hereinafter, the present invention will be described in more detail based on examples and comparative examples.

[Comparative Examples 1 to 2 and Examples 1 to 10]

Comparative Examples 1 to 2 and Examples 1 to 10 relate to deodorizing and deodorizing effects of ammonia accompanying the simultaneous secretion of bodily fluids, and it is a method of manufacturing a conventional sanitary napkin comprising a liquid permeable top sheet, a superabsorbent polymer tissue and a liquid impermeable back sheet , And Comparative Example 2 was prepared by adding 1% by weight of Eucalyptus oil to the total weight of the sanitary napkin in Comparative Example 1 above.

Examples 1 to 9 were prepared by adding Eucalyptus oil to the composition of Comparative Example 1 at 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8 and 0.9 wt%, respectively (Table 1).

5 g of each of the same female menses was taken during the menstrual period and applied to the surface of the sanitary napkin prepared in Comparative Examples 1 to 2 and Examples 1 to 9 in the air, respectively, and then each was immersed in an inert atmosphere (for example, nitrogen, The initial concentration was measured in 5 minutes using a gas detection method (eg, GC), and the concentration was measured after 1 hour to calculate the deodorization ratio of ammonia. In other words,

As can be seen from the above Comparative Examples 1 to 2 and Examples 1 to 9, it can be seen that when eucalyptus oil is added to the conventional disposable sanitary napkin product, the deodorizing ability of ammonia accompanying the excretion of menstrual blood is excellent.

[Comparative Examples 3 to 5 and Examples 10 to 15]

Comparative Examples 3 to 5 and Examples 10 to 15 show the skin protection effect against horny rash and dermatitis which may appear when the disposable sanitary napkin is worn, and it is composed of a liquid permeable top sheet, a super absorbent polymer sheet and a liquid permeable back sheet, A conventional disposable sanitary napkin product manufactured according to the disposable sanitary napkin manufacturing method was referred to as Comparative Example 3. In the conventional disposable sanitary napkin composition, eucalyptus oil is contained in the liquid-permeable upper sheet in a weight ratio of 0.01%, 0.1%, 1%, 5%, 10%, and 20% The disposable sanitary napkin product of the present invention produced in accordance with Examples 10 to 15 was described. In Comparative Examples 4 to 5, the conventional disposable sanitary napkin product was made to contain the compounding disinfectant Katon CG in a liquid permeable top sheet at a weight ratio of 1% to the total weight of the disposable sanitary napkin, respectively, . In Comparative Examples 3 to 5 and Examples 10 to 15, 100 menstrual women between 20 and 50 years old were directly used during menstruation period to examine the degree of itching and dermatitis.

(Table 2) is a table in which the skin symptom at the site of use is classified into five grades by the examiner after using the disposable sanitary napkin prepared in Comparative Examples 3 to 5 and Examples 10 to 15 during the menstrual period.

As shown in Comparative Examples 3 to 5 and Examples 10 to 15, the ratio of the skin grade 0 was about 30% in the conventional disposable sanitary napkin product (Comparative Example 3). Compared with Comparative Example 3, % And 26%, respectively, while the women's cleanser had a weak skin protection effect, whereas the chemical synthetic fungicide, ketone, proved to irritate the skin. In Examples 10 to 15 in which 1-menthol was added to the conventional sanitary napkin product (Comparative Example 5) in comparison with Comparative Examples 3 to 4, the ratio of the skin-0 grade was about 51 to 70% Rash and dermatitis. This is thought to be due to alleviation of symptoms of dermatitis and rash by preventing skin alkalization by menses. In addition, it is thought that Eucalyptus oil is antimicrobial and sterilizing action on the skin.
