Description

1259775 玖, invention description: [Technical field of invention] 3 FIELD OF THE INVENTION The present invention relates to an absorbent article such as a diaper, a diaper, a diaper, a sanitary napkin, a sanitary pad, and the like. More particularly, the present invention relates to an absorbent article for applying a skin care composition to at least a portion thereof, the composition being delivered to the skin of the user by normal contact and movement and/or body heat of the user. L «tr - ϋ. Jt 10 BACKGROUND OF THE INVENTION Absorbent materials are used to absorb aqueous liquids in the preparation of sanitary articles such as baby diapers or sanitary napkins. To avoid direct contact with the absorbent material during use and to increase ease of use, the material is covered with a thin, water permeable nonwoven. Nonwoven materials of this type are typically prepared from synthetic fibers such as polyolefin or polyester fibers because of their low cost of manufacture, good mechanical properties and thermal stability. In the sanitary article industry, skin affinity emulsions are increasingly provided in this type of nonwoven material to enhance overall tolerance and ease of use. For example, DE 33 09 530 C1 describes a sanitary absorbent pad which is impregnated with a skin care material consisting of triglycerides and/or partial glycerides of coconut fatty acids having 8 to 18 carbon atoms. . In order to avoid problems in the transfer of the preparations from fabric to skin during use, the selection of the mixture of DE 33 09 530, triglyceride S and partial glycerides is such that it has between 35 and 40 The rising point in the °C range. 1259775 Another method of delivering skin care substances to the skin during use is shown in WO 96/16682. It describes a diaper having an inner cover network prepared from an emulsion which is solid or semi-solid at 2 ° C and delivered to the user at the time of use. The emulsions comprise from 10 to 95% of a non-aqueous emollient which is plastic or liquid at room temperature and has a melting point of at least 35 from 5 to 90%. However, it is preferably a so-called brake agent. 10 Terrorism, the main problem with knowing the emulsion is its storage stability. At the skin temperature is about 36 money. c. The emulsion itself must be in a form that it can be delivered to the skin without difficulty from the fabric; that is, the viscosity of the emulsion at these temperatures should be sufficient to separate and transport to the skin without the fabric. However, if the hygienic product is stored at a relatively high temperature, such as above the machine, this method of temperature dependence may be a problem. In this case, it is usually observed that = out: not on the fabric material. Therefore, the skin affinity emulsion of the non-woven material of the object of the present invention 15 ensures the storage stability of the far solution, particularly the storage stability at high temperatures. Body infiltration ==::=! The non-woven fabric in the diaper must have a liquid skin hydrophilicity. In the case of pass 2 low loss and (4) pass-through-- money (4) delivery to use I kg (4) (4) purely non-fabric transmission = in terms of selectivity, optionally provide additional growth. Rationale: The formation or reduction of bacteria, fungi and yeast extracts must be able to apply the emulsion to the non-woven material easily and as much as possible using known preparation methods, light 20 1259775. It has been found that products using prior art techniques do not fully achieve these properties. The emulsion composition is typically applied to the absorbent article or a material intended for use in the article in a dazzling state. It is generally between 35 and 1 inch. (: between one and five temperatures. Once the molten emulsion is applied, it is allowed to cool and solidify on the surface of the article or material to which it is applied to form a cured coating. Any suitable application method can be used, such as Trough coating method, extrusion coating method, gravure coating method, and spray coating method. A major problem faced when applying the emulsion composition to an absorbent article or a 10 material planned for the article is The manufacturing process is generally a very fast method, and the molten emulsion cannot be sufficiently cured before the article or material is folded or wound, causing the smearing of the emulsion. The emulsion may further penetrate the surface layer of the article to which it is applied and enter. Absorbing the core to make it hydrophobic and reducing its absorbability. 15 [Injection of the internal solution] SUMMARY OF THE INVENTION One object of the present invention is to provide an absorbent article comprising an emulsion of the above type which overcomes or at least reduces The problem of smearing during the manufacture of the article and the problem of the material applied by the osmotic emulsion. 20 Surprisingly, it has been found that The above-mentioned object is achieved by the three components selected for the stunning nature.

BRIEF DESCRIPTION OF THE DRAWINGS 15 Fig. 1 is a perspective view of an absorbent article in the form of a diaper. The 苐2 diagram is a section through a section of an absorbent article. C实旌^方式] Detailed Description of the Invention The term "absorbent article" refers to a product placed in contact with the skin of a user to absorb and contain body exudates such as urine, feces and menstrual fluids. The invention mainly refers to a disposable absorbent article, which means that the article is not expected to be recovered or reused by washing or otherwise as an absorbent article after use. Examples of disposable absorbent articles include feminine hygiene products such as sanitary napkins, sanitary care. Pads and sanitary trousers; diapers and diapers for infants and incontinent adults 10 1259775 pants; incontinence pads; diaper pads, etc. The figure shows a diaper i for a baby or an incontinent adult, the structure of which is typical The ground comprises a liquid permeable surface layer 2, a liquid impermeable bottom layer 3 and an absorbent body 4 enclosed therebetween. The liquid permeable surface layer 2 may comprise a non-woven material such as a spunbond type, a meltblown type, Carding type, hydroentangled type, wet-laid type, etc. Suitable non-woven materials may be composed of natural fibers such as wood pulp or cotton fibers, or rayon fibers such as polyester, polyethylene, a composition of propylene, an adhesive fiber, or the like, or a mixture of natural and man-made fibers. The surface material may be further composed of two kinds of 10 fibers bonded to each other in a bonding mode, as disclosed in EP-A-1 035 818. Other examples of materials are porous foams, porous plastic films, etc. Materials suitable as the surface layer material should be soft and non-irritating to the skin and liquids such as urine or menstrual fluid can penetrate. The liquid impervious bottom layer 3 can include A thin plastic film, such as a polyethylene 15-ene or polypropylene film, coated with a non-woven material of a liquid impermeable substance, a hydrophobic non-woven material that prevents liquid penetration, or a plastic film and a non-woven film. a laminate of a material. The underlayer material may be breathable, thereby allowing vapor to escape from the absorbent core while preventing liquid from passing through the underlying material. The planar extension of the surface layer 2 and the underlying material 3 is slightly greater than that of the absorber 204, and Extending beyond the edge of the absorber. Layers 2 and 3 are joined to each other at their extensions, such as by gluing or by heat or ultrasonic fusion. Surface and/or The layer may be further bonded to the core of the absorber by any method known in the art such as adhesive, thermal bonding, etc. The core of the absorber may also not adhere to the surface layer and/or the bottom layer. 1259775 Any of the conventional types. Examples of common absorbent materials are fiber short, cotton paper, high body (tetra) (so-called superabsorbent), absorbent foam, absorbent non-woven material, etc. The 甬-absorber is a mixture of fibrous fibril pulp and superabsorbent. It is also common for the two bodies to comprise layers of different materials having different properties in terms of liquid absorption capacity, liquid distribution ability and storage capacity, which are familiar to those skilled in the art: Therefore, there is no need to elaborate on it. For example, a thin absorbent body commonly found in baby diapers and incontinence guards typically includes a compressed mixed or layered structure of one of fibrous batt and superabsorbent. The size and absorption capacity of the absorbent core (4) can be varied to suit different uses, such as infant urine #, adult incontinence diapers and pads, diapers, sanitary pads, sanitary napkins, and the like.

The diaper disclosed in Fig. 1 is intended to surround the lower half of the user's body in the form of an absorbent trouser. The condition of the package is planned to be worn on the front side of the front of the user's body during use; during the period of use, it is planned to be worn on the surface of the user's body, the surface of the moon, α, 6 and a narrower between the front and the back. The ankle portion 7, and its system, are intended to be placed over the ankle between the user's legs. The front portion 5 has a pair of tape sheets 8 or other types of bonding members such as hook-and-loop type fastening members. The diaper includes elastic side hem 10 that forms a leg opening. The elastic system is provided by a resilient member 11 that is secured between the skin and the bottom layer of the side hem region 10. The diaper disclosed in Figures 1 and 2 further includes an elastic barrier hem 12 having a proximal edge 13 and a distal edge 14, and an elastic member 15 separating the distal edge 14 from the skin region. The barrier hem 12 forms a leak-proof barrier, and its proximal edge U is fixed to the surface layer 2 in the region of the side hem 1 or above the absorbing core 4 near the trailing edge of the absorbing core 12 1259775. The diaper may further comprise an elastic waist member in the form of a resilient member that extends laterally across the waist portion of the article. In another embodiment, the diaper includes a 5 strap portion that is bonded to the back portion of the diaper and is intended to be tied together around the waist of the user. The fastening member of the front portion of the diaper is then adhered to the outside of the strap to form the diaper into the desired shape of the pants. An example of a lace-up diaper is shown at w〇 01/00129. However, it should be understood that the diaper shown in the above figures represents only one non-limiting example, and the invention is not limited thereto and can be used in any of the types of absorbent articles defined above. The absorbent article of the present invention has a skin care composition in at least a portion thereof whereby the composition is delivered to the skin of the user by normal contact, movement of the user and/or body heat. When delivered to the user's skin, the skin care 15 composition provides the desired skin treatment or protective benefits, such as reducing red marks, erythema, diaper dermatitis, and irritating the skin. The occurrence of diaper dermatitis or diaper rash is caused by a combination of several factors. Moist skin makes it easier for friction and pressure to break the skin. The high moisture content also means that the stimulating substance may penetrate the skin and the effect may be increased, and the bacteria and fungi may breed. The air-impermeable skin and urea in the urine decompose into ammonia, causing an increase in pH. Higher pH results in enzymes from the small intestine (lipases and proteases) and microorganisms from the secretions, which can break down the skin more. It can easily develop into a vicious circle in which the factors promote and strengthen each other. 13 1259775 Best to prevent dermatitis by creating conditions to eliminate the effects of these factors that cause and maintain the development of diaper dermatitis. Therefore, efforts should be made to keep the skin dry as much as possible, often to allow the skin to breathe and replace wet diapers. The mechanical shear force should be reduced to a minimum of 5 by selecting the smoothest and softest material possible; and the wear between the diaper and the skin is reduced. By providing a skin-softening and protective lotion or cream, the barrier layer can be further enhanced to prevent the intrusion of irritating substances or enzymes. In the case of more severe dermatitis, the damaged skin is infected with microorganisms and requires treatment with a more active drug. At this time, an ointment with cortisone and various fungicides and bactericidal bacteria is used. The skin care composition can be applied to any portion of the article that is in direct contact with the skin of the user during use or that is in contact via the permeable surface layer. The parts include the skin 2 or portions thereof, the elastic side hem 1 阻, the barrier hem 12, the strap in the lace diaper, the elastic elements in the side hem, the barrier hem and/or the 15 臊Part. The skin care composition can also be applied to fibers contained in the nonwoven material, and to the two fibers of the two materials. The skin care composition according to the present invention is solid at 21 ° C, and at least comprises: a) 5 to 70% by weight of a component which melts in the range of 25 to 37 ° C, which is selected from the group consisting of synthetic waxes , paraffin wax, fatty acid ester, polyhydroxy fat 20 decyl ester, fatty alcohol, alkoxylated fatty acid ester, alkoxylated fatty alcohol and mixtures of such compounds; b) 5 to 70% by weight of one component, Its melting point is at least 5QC higher than the melting point of component a), and component b) is derived from the following groups: stone butterfly, poly-based fatty acid ester, Cl4-22 fatty alcohol, C12j2 fatty acid, fatty alcohol and fatty ester Alkoxylated derivative 14 1259775 Organisms and mixtures of such components, wherein the composition additionally comprises the following components: C) 5 to 25% by weight of one of the crystallization promoters selected from the group consisting of: Partial glycerides, ethylene glycol diesters, and polymeric waxes, provided that the melting point of the crystallization 5 action promoter is in the range of 45 to 70 ° C; and the composition comprises less than 5% by weight of water. Melting is defined by the input of thermal energy, in which the amplitude of the oscillation of the particles is so large that the lattice structure collapses as a result of the increase in the kinetic energy of the particles, causing a substance to change from a solid to a liquid. Melting point 10 is defined as the temperature at which the liquid phase and solid phase of a substance are in thermal equilibrium at a pressure of typically 1013 kPa. In reality, however, the term "melting point" is actually mostly used as a transition point from a solid to a liquid state, rather than as a transition to the opposite direction of action. The heat absorbed during this process is called heat of fusion or melting enthalpy. Although there are exceptions, the melting point generally increases with increasing pressure. For many pure materials, the melting point can be accurately determined because during heat introduction, the temperature remains constant for a specific time interval. The amorphous glassy material has no specific melting point because there is no crystalline crystal lattice. A similar phenomenon is observed in the melting properties of fat, ointment, cream or suppository materials; in these cases, the cure point, so-called rise and fall points, may be used in the 20-characteristic analysis. It should be understood that the action of the crystallization promoter means that it has a very precise melting point, and the melting point must be higher than the melting point of the liquid to semi-liquid component a), but must be lower than the application temperature of the emulsion. The combination of component a) which melts at a lower temperature and component b) which melts at a higher temperature, and the simultaneous addition of crystallization as a promoter for C 15 1559775, firstly make the emulsion have storage stability even at high temperatures, At the same time, it can be delivered from the object to the user's skin during use. Component a) may be selected from a wide variety of compounds known to those skilled in the art, and the melting point must range from 25 up to 37 °C.
