Embodiment I

[0101] The component fibers of the topsheet are bicomponent fibers available from Chisso Corporation, Tokyo, Japan under code ESC052. An initial finishing oil was prepared which was obtained from Sanyo Chemical Industries Ltd., Kyoto, Japan under the code Sunoil F. Condensed tannin (obtained from Rilis Scientific Industry Co., Ltd., Osaka, Japan under the code Pancil COS-6A) was dissolved in the finishing oil. The component fibers are treated with the resulting finish oil by the touch roll method. The resulting fibers were fried and cut into staple fibers (ie, about 51 mm in average length), which were formed into nonwoven webs by card-forming thermal bonding methods and (or air-through methods). The resulting topsheet material has 18 g / m 2 basis weight.

[0102] The absorbent core is formed from an airlaid tissue material having a 90 g / m 2 and available from KNH under code A902.

[0103] The backsheet is formed from a microporous polyethylene film having a 37 g / m 2 and ...

Embodiment II

[0105] The compositions exemplified in Table 1 are representative of carrier systems (or materials) for body treatment compositions. The carrier system is typically prepared by mixing petrolatum and a fatty alcohol, such as behenyl alcohol, by weight, then heating the mixture to about 80°C while stirring with a low speed propeller stirrer. Next, a viscosity agent or thickener is added to the mixture and the ingredients are shear mixed into the final carrier system. Suitable viscosifiers or thickeners include beheneth-10, fumed silica, bentonite and steareth-2, wherein the viscosifier or thickener can be used alone or Use in combination. The ingredients can be shear mixed using an IKA Ultra Turrax shear mixer at 1151.9 rad / sec (11,000 revolutions per minute).

[0106] Alternatively, petrolatum, fatty alcohol, and viscosity or thickener can be mixed and heated at 80°C with stirring to melt the ingredients, then stirred into the final carrier system using a high-speed blade agi...

Embodiment II-IX

[0120] Examples II to IX below, illustrated in Table 2 below, are representative of body treatment compositions comprising the identified carrier in Table 1 . The body treatment composition is prepared by making a pre-mix solution of zinc oxide body treatment, adding the zinc oxide pre-mix to other body treatments and any optional ingredients such as panthenol and glycerin, or by making hexamethylene A body treatment solution of Bito and Niacinamide skin treatments and any optional ingredients. The body treatment solution is then added to a carrier system such as those described in Table 1, wherein the body treatment solution and carrier system are heated to a temperature of about 80°C with agitation. All ingredient levels are by weight of the body treatment composition. These body treatment compositions are especially effective in controlling skin disorders such as skin erythema, malodor and bacterial skin infections.

Abstract

The invention is directed to an absorbent article comprising a condensed tannin. The condensed tannin is extracted from a plant family which is selected from the group consisting of Ebenacea, Mimosoideae, Apiaceae, Pinaceae, Rosaceae, Fagaceae, and mixtures thereof. Since the condensed tannin has more hydroxyl groups and larger molecular structure than general polyphenol organic compounds, it cantrap malodor molecules more effectively than the general polyphenol organic compounds. In addition, the absorbent article of the invention can also provide a body treatment that protects the wearer'sbody and provides body comfort.

Description

field of invention [0001] The present invention relates to absorbent articles worn in contact with the body of the wearer. In particular, the present invention relates to absorbent articles such as pantiliners, sanitary napkins, tampons, interlabial pads, incontinence pads, diapers, breast pads, sweat pads and the like. More particularly, the present invention relates to an absorbent article comprising condensed tannins. Background of the invention [0002] Absorbent articles, such as sanitary napkins, pantiliners and incontinence pads, are typically worn in the crotch region of undergarments. These devices are designed to absorb and retain fluid and other excretions from the body to prevent soiling of the body and clothing. Absorbent articles are typically placed within clothing (eg, the wearer's panties) and worn between the wearer's legs, next to the genital (or source of fluid discharge) area of ​​the body. Disposable absorbent articles generally comprise a fluid-perm...
