Description

Disposable diaper comprising skin protecting agent

The present invention relates to a disposable absorbent product containing a skin protectant to have an antibacterial and anti-itch effect. More specifically, the present invention applies natural vegetable skin protectants such as baicalin and quercetin to disposable diapers and sanitary napkins, which are important for hygiene, and various organic and fecal substances generated from excretion produced by physiological action. The present invention relates to a disposable absorbent product that provides anti-inflammatory, antibacterial and anti-allergic functions to bacteria and microorganisms as well as inorganic pollutants.

In general, skin irritation, erythema (redness), and dermatitis caused by secretion absorbent products may cause strong pressure to fix the absorbent body to the body, and to absorb saturated skin and mucous membranes. After physicochemical factors such as tissue swelling and the absorbent are wetted with secretions, fermentation and decay occurs due to contamination of the skin flora and enterobacteriaceae, and alkaline or acidic substances are generated and the pH of the skin adhesion site is increased. It is well known that there are microbiological factors that result from inducing out of the pH range of 6.0 to 7.5 or by producing by-products that are irritating to the skin.

In the present invention, the disposable absorbent product refers to a product that absorbs various physiological human secretions, and a product that absorbs large, urine, menstrual or vaginal secretions, and more specifically, a disposable diaper used by an infant or an adult ( diaper; nappy, sanitary belt, towl or napkin, panty liner, tampon, and the like.

As shown in FIG. 1, it consists of the absorbent body 3 which consists of a liquid permeable top sheet 2, a fluffy pulp, a superabsorbent polymer 3 ', etc., and a liquid impermeable back sheet 1, and cuts off both sides of a cuff. The conventional disposable absorbent product in which (4) is formed is produced in the fermentation metabolism process of urine urea in feces or skin, especially candida albicans, when urine is kept on. Ammonia produced by fermentation and decay by urease causes a rise in pH and prevents skin's inherent ion balance, causing skin side effects. Likewise, harmful bacteria are propagated from menstrual or vaginal secretions. There was a problem that causes a change in pH and unpleasant odor.

As a biological diaper rash prevention method that has been generally tried in the past, a method of killing human flora including ammonia-producing bacteria by treating fungicides and a method of suppressing a rise in pH by dilution by adding various organic acids have been used. As such, the organic acids used for suppressing the pH rise include citric acid, adipic acid, azelaic acid, malic acid, tartaric acid, gluconic acid, rutaric acid, leblenic acid, glycolic acid, succinic acid, fumaric acid, pimelic acid, sumeric acid and sebacic acid. Although methods using weak acid substances such as these have been used, their pH is in the range of 3.0 to 5.5, and the skin irritation may be as good as skin rashes due to ammonia formation in a state away from the physiological pH of 6.0 to 7.5. Actually, the pH increase due to the formation of ammonia does not buffer at a certain range of pH, but only slows the rate of increase. In addition, some products use a method of treating petroleum jelly on the liquid permeable top sheet 2 to suppress skin rash caused by friction between contact with feces and skin, but the effect is insignificant. This may be due to the fact that petrolatum is coated on the skin to reduce friction and partially block skin contact with feces, but it is impossible to completely block it, and to relieve secondary sores or inflammation for more effective sores. It is necessary to add substances that have anti-inflammatory or bactericidal properties.

Therefore, the present inventors have conducted research to manufacture a functional absorbent product having improved skin anti-germ function in the existing disposable absorbent product, and as a result of the skin irritation by adding a natural vegetable skin protection agent such as kalkaline and quercetin, The present invention has been accomplished by discovering that it can relieve sores or inflammation.

SUMMARY OF THE INVENTION An object of the present invention is to apply natural vegetable skin protectants such as bicalin and quercetin to a disposable disposable diaper and sanitary napkin, which are important for hygiene, to a conventional disposable absorbent product including an absorbent, and thus, various kinds of excretion generated from excretion produced by physiological action The present invention provides a disposable absorbent product that provides anti-inflammatory, antibacterial and anti-allergic functions to organic and inorganic sources as well as bacteria and microorganisms.

Disposable absorbent products containing a skin protector according to the present invention is a disposable absorbent product comprising a liquid permeable topsheet, a liquid impermeable backsheet, and an absorber positioned therebetween, wherein the absorbent product includes bicalin or quercetin as a skin protectant. It comprises at least one of the same natural vegetable skin protectant.

The natural vegetable skin protectant is preferably comprised between the liquid permeable topsheet or the liquid permeable topsheet and the absorber.

The natural vegetable skin protectant is included within the range of 0.001 to 30% by weight based on the standard weight of the entire product.

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

1 and 2, the disposable absorbent article containing the skin protector according to the present invention is a liquid permeable topsheet 2 and a liquid impermeable backsheet 1 and an absorbent body 3 disposed therebetween. Disposable absorbent product comprising a, at least one or more natural vegetable skin protectant, such as Baikallin or quercetin as a skin protectant in the absorbent product.

Disposable absorbent articles consisting of a liquid permeable topsheet 2 and a liquid impermeable backsheet 1 and an absorber 3 positioned therebetween are known to be commercially available and available.

As the liquid permeable top sheet 2, a synthetic nonwoven fabric or a film having a hole is used so that body fluid can quickly pass through the absorbent body 3. As the synthetic nonwoven fabric, a hydrophilic treatment is usually used for hydrophobic fibers in order to quickly deliver the body fluid to be absorbed by the absorber 3.

The liquid impermeable backsheet 1 functions to prevent body fluids absorbed by the disposable absorbent product from leaking under the absorbent body 3 and contaminating the wearer's clothing or the surrounding environment, and mainly uses polyethylene film. The nonwoven fabric may be adhered to a polyethylene film to improve the softness of the material.

The absorber 3 is typically made of fluff pulp, superabsorbent polymer 3 '(SAP; super absorbent polymer), tissue (5), and the like, and includes a liquid permeable upper sheet (2). Absorbs the passing feces at high speed and retains the absorbed feces to prevent the absorbed feces from contacting the skin again.

In the present invention, a natural vegetable skin protection agent is included between the top sheet 2, the top sheet 2 and the absorbent body 3, between the back sheet 1 of the absorbent body 3, and the like.

The skin protective agent may be preferably Baikallin and quercetin, but the present invention is not limited thereto, and any one that exhibits pharmacological activity having a skin protective function may be used.

The Baikal is extracted from the medicinal plant, Gold, is known to have anti-allergic and anti-inflammatory effects. The quercetin is a kind of flavonoids widely distributed in plants, and is used as an antioxidant or an anti-capillary penetration agent. Anti-inflammatory effects are also known. It is also known that these Baikalins and quercetin are extremely safe with little irritation to the skin.

The natural vegetable skin protectant is preferably comprised between the liquid permeable topsheet 2 and the absorbent body 3. This is especially the position closest to the human body, and also the skin sores and also the friction with the liquid permeable top sheet 2, which is located closest to the skin, the wetting and contamination of the top sheet 2 and the top sheet 2 The direct contact between the absorber 3 and the skin due to deformation or the like, or the secretion absorbed by the absorber 3 once is most likely to come into contact with the skin when drawn out of the absorber 3 again by deformation or denaturation of the absorber 3 itself. Part.

The natural vegetable skin protectant is included within the range of 0.001 to 30% by weight based on the standard weight of the entire product. The amount of the vegetable skin protectant used may vary depending on the degree of anti-inflammatory and anti-allergic effects of the skin protectant according to the person to be used of the product and the size and type of use thereof. For example, each of Baikallin and quercetin alone or These may be used in combination with each other, and in addition, they may be used in combination with other skin protection agents having pharmacological activity such as conventional skin protection and anti-inflammatory. In addition, it may be different depending on the application site of the disposable absorbent product, and the formulation of the skin protection agent may be applied in any form of powder, lotion or liquid. Specifically, the natural vegetable skin protectant is included within the range of 0.001 to 30% by weight based on the standard weight of the entire product. If the amount of the vegetable skin protection agent is less than 0.001% by weight based on the standard weight of the entire product, there may be a problem in that it is difficult to obtain a desired skin protection effect, if the amount is more than 30% by weight, the current disposable absorption Not only is it difficult to apply to a product on a product basis, there may be a problem that affects the shape and mass of the product.
