Problems solved by technology

[0005] By pre-applying pharmaceuticals such as emollients and skin care agents to absorbent products, it is possible to suppress the occurrence of rashes, or to seek to cure rashes, but the use of existing absorbent products coated with the above-mentioned pharmaceuticals is difficult for the skin of the wearer. sometimes rash

no. 1 Embodiment approach

[0020] figure 1 (A) is a schematic view when the absorbent product according to one embodiment of the present invention is held in a tense state and viewed from above, figure 1 (B) is to figure 1 The diaper shown in (A) is kept in its natural state, at an equivalent figure 1 (A) Schematic diagram of the cross-section when the portion of the IB-IB line shown in (A) is cut.

[0021] Here, the "upper surface" of the absorbent product in this specification refers to the upper surface of the absorbent product placed with the surface contacting the wearer's body surface side upward when worn. In addition, "maintaining the absorbent product in a tense state" refers to applying tension to the absorbent product in its width direction and longitudinal direction and maintaining it so that the deformation caused by the shrinkage of the elastic body provided in the absorbent product is substantially reduced. disappeared.

[0022] The illustrated absorbent article 70 is an unfolded disp...

no. 2 Embodiment approach

[0096] The biggest feature of the diaper 70 of this embodiment is that the diamide derivative represented by the above formula (I) is applied to the top sheet 11, the waist flaps 30a, 30b, the body flaps 35a, 35b, and the leg flaps 45a, 45b respectively. On the inner side (the side in contact with the wearer's skin) or a part thereof.

[0097] The above-mentioned diamide derivatives are transferred to the wearer's skin along with the wearing of the diaper 70, and play the following functions: (1) prevent excrement from directly contacting the wearer's skin, and suppress skin irritation caused by the excrement, (2) ) weaken the friction between the skin and the diaper, reduce the skin irritation caused by the diaper, (3) improve the water retention capacity and barrier function of the stratum corneum after being absorbed through the skin, and the diamide derivative functions as an oily skin care agent. Thus, the diaper 70 suppresses rashes.

[0098] As the above-mentioned diam...

Embodiment 1

[0120] Except in areas 45a, 45b ((refer to figure 1 (A) Except that the water-soluble skin care agent and the oily skin care agent were not applied, an unfolded diaper having the same structure as the diaper 70 of the embodiment was produced.

[0121] At this time, as the surface sheet 11, a core-sheath composite fiber with a fineness of 3.3 dtex and a weight per unit area of ​​30 g / m was used, in which the core component was polypropylene and the sheath component was polyethylene. 2 of non-woven fabrics. On the above-mentioned core-sheath composite fiber, before it is made into a non-woven fabric, it is coated and mixed with witch hazel extract (1,3-butanediol extract) as a water-soluble skin care agent, and a hydrophilic surfactant polyoxygen. Ethylene sorbitan monolauryl (HLB=13.3), hydrophobic surfactant sorbitan tristearate (HLB=2.1), monoalkyl phosphate potassium salt, antistatic agent, lubricant, etc. Coating solution. When preparing the coating liquid, the added amo...

Abstract

The present invention provides an absorbent article (70) capable of suppressing rash of skin in regions which come into contact with a gather portion of the absorbent article, by applying a water-soluble skin care agent and oily skin care agent on the gather portion to be contacted with the skin of a wearer in wearing the absorbent article (70) , and allowing at least a part of the above mentioned oily skin care agent to be transferred to the skin of a wearer when wearing before the above mentioned water-soluble skin care agent is transferred to the skin of a wearer.

Description

technical field [0001] The present invention relates to absorbent articles containing skin care agents. Background technique [0002] Since the diaper is worn for a relatively long time, excretion occurs several times during the period, so the humidity inside tends to become very high due to the action of sweat and excrement. Especially for diapers with creases for the purpose of suppressing leakage, the adhesion to the skin is relatively high in the creases and relatively low in other parts of the diaper. Therefore, the skin part that is in contact with the creases is easy to Sweating, it becomes a state prone to macules due to evaporation. The same can be said about other absorbent products having gathers, such as sanitary napkins, incontinence pads, pantyliners, and sheets for vaginal excretions. [0003] Accordingly, absorbent products that impart skin care effects and suppress the occurrence of freckles have been proposed. [0004] For example, Japanese Patent No. 32...
