    FIELD OF THE INVENTION
    [001] The present disclosure relates to a method for applying a skin beneficial agent to an absorbent article. BACKGROUND OF THE INVENTION
    [002] Absorbent articles such as sanitary napkins and underwear liners sometimes include colored regions to highlight various sections of the article such as the location of the absorbent core in the crotch portion of the article. The ink can be printed on the top sheet material or any other material or layer of the article before or during assembly of the article. Topical additives such as lotions can be added to the article in a way that provides a skin condition benefit to the article user. The lotion addition can be applied by continuous spray or extrusion methods or by printing (Patent Document No. US 2011/0264065).
    [003] There is no need for an improved method of applying additives to absorbent articles, especially costly skin-beneficial agents. DESCRIPTION OF THE INVENTION
    The present invention relates to a method according to claim 1 and an absorbent article according to claim 15 which provides an article and an improved method of application comprising agents beneficial to skin.
    [005] Therefore, the method involves a method of applying a skin-beneficial agent to an absorbent article comprising a topsheet layer having a body-facing surface and a garment-facing surface, the article having a longitudinal front portion, a longitudinal rear portion and a crotch portion located between the rear and the front portion. The method at least entails the step of printing, by means of an in-line synchronized printing technique, a water-based ink composition comprising a binder and a skin beneficial agent microencapsulated in the article, the skin beneficial agent being at least one additive or partially hydrophobic or lipophilic substance, and the microcapsule material is insoluble in water at 20°C.
    [006] The absorbent article therefore comprises a topsheet layer having a body-facing surface and a garment-facing surface, the article having a longitudinal front portion, a longitudinal rear portion and a crotch portion located between the rear and the front portion, and the article having a water-based ink composition comprising a binder and a microencapsulated skin beneficial agent printed by an in-line synchronized printing technique thereon, the agent beneficial to skin is at least one additive or partially hydrophobic or lipophilic substance, and the microcapsule material is insoluble in water at 20°C.
    [007] The skin beneficial agent is added to the article in a convenient and versatile manner that is cost-effective and time-effective. The required machining consumes less space and has low investment costs due to smaller machine operations that add paint and skincare agent together in the same composition and in one process step.
    [008] The costs of skin-beneficial agents are low due to the agents applied in exactly the right place in the article. Skin-beneficial agents are protected from the paint composition during the application stage. The benefit to the user also increases due to the agent being slowly released from the microcapsules during use of the article. A conventional application method results in the agent exposed from the time of application as the agent spread over a large surface area of the article. BRIEF DESCRIPTION OF THE DRAWINGS
    [009] Figure 1 is a top view of a sanitary napkin having an ink composition comprising a microencapsulated skin beneficial agent applied to its topsheet.
    [0010] Figure 2 is a top view of a diaper having an ink composition comprising a microencapsulated skin beneficial agent applied to its topsheet. DETAILED DESCRIPTION OF THE INVENTION
    [0011] As used herein, "skin beneficial agent" is a substance or agent known to a person skilled in the art that has properties that can affect, improve, or maintain a state of skin or mucosal health. In particular, the skin-beneficial agent will have a function in addition to a fragrance or essence. The function can be physical stimulation of the skin such as increased blood circulation so as to maintain a natural balance of cells in the skin or adding a moisturizing effect, vitamin absorption or drug delivery through the skin or mucosa. The function can be a physical change to the substrate so that there is a less skin-damaging microclimate in the absorbent article and/or give an improved function of the substrate material such as a barrier to keep bodily fluids in the absorbent article. The function can be a chemical reaction that leads to a physical sensation such as an observed warming or cooling effect.
    [0012] The skin-beneficial agent function can be activated when the article user makes contact with the skin or mucosa with the skin-beneficial agent.
    [0013] The skin beneficial agent is at least one additive or partially hydrophobic or lipophilic substance. The skin beneficial agent may therefore be at least partially miscible with a hydrophobic substance. The skin beneficial agent may be insoluble in water at 20°C.
    [0014] The skin beneficial agent can be selected from oil, fat or wax or is a mixture or derivative of any thereof. The skin beneficial agent may be from a natural source.
    [0015] The skin beneficial agent can be selected from extracts of plants, herbs, fruits, seeds, spices and oils.
    [0016] The skin beneficial agent can be selected from an extract of any of almond oil, argan oil, sesame seed oil, jojoba oil, grape seed oil, shea butter, sesame oil olive, coconut oil, avocado oil, limonene, linalool, geraniol, citral, coumarin, hibiscus, Lavendula augustifolia, marigold, chamomile, mint, sandalwood, peach, mango, apricot, hawthorn, coffee, chocolate, menthol, xylitol.
    [0017] The skin beneficial agent can also be selected from carbamide, glycerin, dimethicone, tocopheryl (vitamin E), ascorbic acid (vitamin C), allantoin, thymol, salicylates.
    [0018] The skin beneficial agent may also be a synthetic equivalent of natural skin beneficial agents.
    [0019] As used herein, "absorbent article" means an article selected from a sanitary napkin, an underwear liner, an incontinence pad, an incontinence diaper, a belted diaper, a baby diaper or absorbent intimate.
    [0020] The ink composition comprises at least one binder and a microencapsulated skin beneficial agent. The ink composition may, except for microcapsules with skin beneficial agent, be a standard formulation known to a person skilled in the art. The paint composition is water-based. The ink composition can include colored pigments or dyes or it can be colorless. The ink can also include typical printing additives known to one skilled in the art such as solvents, co-solvents and processing aids. The solvent can include among other alcohols, esters, aldehydes and water. Binders may be, but are not limited to, polymers, resins, emulsions and mixtures based on styrenes, acrylates, acetates, alkyds, polyurethanes, nitrocellulose or other cellulose derivatives, polyglycols, polyvinyl butyrates, polyvinyl alcohols, polyvinyl pyrrolidone and derivatives or mixtures of same. Constituents such as dispersants, surfactants, wetting aids, defoamers, defoamers, waxes, silicones, viscosity modifiers, pH regulators, antiskid agents and preservatives may also be present in the paint formula along with one or more of an encapsulated beneficial additive . The binder in the ink composition ensures hardening of the ink as well as keeping the ink including the microcapsules in place on the material.
    [0021] The size of the microcapsules can be at least 1 µm, or at least 3 µm, or at least 10 µm and can be below 100 µm, or below 70 µm, or below 30 µm. The size of the microcapsules can be 1 to 100 µm, or 1 to 70 µm or 3 to 30 µm.
    [0022] The skin beneficial agent is added in the form of microcapsules which make the encapsulated additive closed from the surrounding medium, i.e. the printing ink when applied to the absorbent article material. Closure can be achieved by fully encapsulating an incompatible fluid, such as oil in a water-based paint, by semi-permeable or impermeable water-insoluble walls, or by incorporating the additive into a water-insoluble matrix.
    [0023] The additive microencapsulation technique is known for other uses such as cosmetics. Examples of companies producing such microcapsules are Devan Chemicals, Belgium; Encasys, USA; Micro Capsule Technologies, France; and Robert Blondel, France.
    [0024] Microencapsulation can be done through emulsion polymerization in water-in-oil emulsions to create emulsions, dispersions or dry powders. Typical shell materials include compositions based on silica, melamine and polymers. The microcapsule material can be a composite of melamine and silicone polymers. The microcapsule material is insoluble in water at 20°C.
    [0025] The skin beneficial agent is microencapsulated and can be added to the paint composition as an emulsion, dispersion or as a powder. The concentration of microcapsules in the resulting ink composition and the amount of ink composition applied to the absorbent article can be determined by a person skilled in the art by routine experimentation and formulated for each specific use. The concentration of microcapsules depends on the beneficial agent used and the desired effect of the article. The amount of ink applied to the absorbent article will depend on the composition of the ink and the desired pattern in the article. The amount of ink needed may also vary depending on surface absorption.
    [0026] The concentration of microcapsules in the article may be at least 0.001 g/m2, or at least 0.01 g/m2 or at least 0.1 g/m2 or at least 0.05 g/m2 and below 5 g/m2, or below 1.0 g/m2 or below 0.6 g/m2. The concentration of microcapsules in the article can be 0.001 to 5 g/m2, or 0.01 to 1 g/m2 or 0.05 to 0.6 g/m2.
    [0027] The skin beneficial agent can be applied on 0.1 to 40% of the area of the article, such as 0.1 to 25%, such as more than 0.1% and less than 10% of the article, or more 0.1% and less than 5% of the article.
    [0028] One advantage of microencapsulation of skin-beneficial agents is that agents that would be incompatible with the ink can be added and dispersed appropriately as microcapsules. A further advantage is that agent release is gradual during use of the article and the inherent smell, if any, will be reduced in the manufacturing operation as well as in stock.
    [0029] The ink composition is applied by printing onto the absorbent article. By print, herein, is meant any type of application requiring a fluid to form a coating or other dry layer on a substrate. By precision, it means that the average will be placed in designated areas on the substrate, rather than in a poorly controlled manner such as when using an extrusion or spray technique. Printing can be contact type as selected from flexoprint, screen printing, offset printing, gravure or non-contact type as selected from digital inkjet which can be continuous or drip on demand, drop formation piezo flashing, heat activated technology, or other technology.
    [0030] Designated areas can be functional zones in the product where the skin-beneficial additive is precisely located through in-line synchronized printing to provide optical performance of the particular additive in the product, i.e., where the substance will be most effective, eg most beneficial part of the product.
    [0031] The ink composition is applied by an in-line synchronized printing technique, which allows an exact placement of the ink composition.
    [0032] In-line synchronous printing steps can be incorporated as steps in a process of manufacturing absorbent articles, or the layers can be in-line synchronously printed prior to product assembly.
    [0033] After applying the ink to the absorbent article, any solvent will evaporate so that the ink dries almost instantly. However, a drying step can be added, such as blowing hot air on the printed surface.
    [0034] The paint composition can be applied to selected areas as desired, and in any desired pattern. The present method allows for very accurate models and fine lines and dots to be formed.
    [0035] When disposed on the absorbent article, the topsheet has a body-facing surface and a garment-facing surface. The paint composition can be applied to one or both of said surfaces. By applying the paint composition to the body-facing surface, the user gains direct access to skin-beneficial agents. By providing the ink on a surface facing the garment, slower activation and release of microcapsules is achieved, which may be desired for certain applications. The skin beneficial agent can also be applied to an intermediate layer of the article.
    [0036] Depending on the location of the ink, several advantageous functional effects can be obtained. Examples of ink models with different functions are shown below. These designs can be used individually, but they can clearly be advantageously combined to achieve the desired characteristics of the absorbent article.
    [0037] The paint composition can be applied as one or more liquid barriers along at least a part of the longitudinal side edges, where the liquid barriers can be formed by continuous or dotted lines. Additionally, a set of paint composition dots can be applied to a central part of the article.
    [0038] The microencapsulated beneficial agent may be printed on an area or zone of the article selected from: - along the longitudinal lateral ends of the crotch portion; - a central area of the crotch portion; - a central area of the front portion; - a central area of the rear portion.
    [0039] The absorbent article may further comprise a flap extending from each longitudinal side end of the article and the microencapsulated skin beneficial agent may be printed in an area of said flaps.
    [0040] The printed zones or areas can be a zone or area that has an arrow, heart, moon, circular, oval, etc. shape. and placed in certain regions of a product to present a unique function.
    [0041] The absorbent article comprises at least one topsheet layer and, if desired, also a backsheet layer and an absorbent layer disposed between the backsheet and topsheet layers.
    [0042] Each layer of the absorbent article has a garment-facing surface and a body-facing surface, and ink can be applied to any of said surfaces. The ink composition can be added to an intermediate layer, such as an acquisition layer located below a top sheet.
    [0043] The present invention also relates to an absorbent article having an ink composition comprising a microencapsulated skin beneficial agent printed thereon.
    [0044] The absorbent article may comprise a topsheet-facing body of a non-woven, a film or laminate thereof or a foam, and a backsheet of a liquid-impermeable polymeric film material or a laminate of a film and a non-woven material and an absorbent layer comprising pulp and/or superabsorbent material and/or fibrous web.
    [0045] The back sheet material can be aerated or non-aerated. The backsheet faces away from the wearer during use, and is opposite the body facing the topsheet layer of the absorbent article. A means of attachment can be applied to the garment facing the side of the backsheet, which can be covered with silicone paper or single packaging.
    [0046] The activation of the microcapsules can be performed by mechanical activation in which the capsule breaks by a shear force or by pressure on contact. Microspheres will break due to user movements. Not all microcapsules will break at the same time as some may be buried deeper in the material and therefore there will be a slow and continuous beneficial release of the agent during use of the article. A lasting effect, therefore, can be achieved.
    [0047] Print application allows for precise placement of a delicate printed pattern in selected areas of the article, compared to when an additive is applied, for example, as a constituent of the spin finish on a top sheet, namely, in a cocktail, which is commonly used by nonwovens suppliers. To further enhance the benefits, printing is combined with precise in-line positioning (synchronization) of any product's print. This allows the print to be placed in zones or areas, that is, particular functional zones of the product. In this way, the skin beneficial agent will be applied only to the imprinted areas, therefore, it allows less quantity and possibility for adapted areas. The in-line synchronization of printing and the microencapsulated skin-beneficial agent also allows blemish-masking, if any, from the skin-beneficial agent by including pigment (or pigments) or dye (or dyes) in the ink composition. Encapsulated skin beneficial agents are well protected from additional constituents in the paint composition during and after application to the article.
    [0048] The disclosure will be described by way of example with reference to the Figures.
    [0049] Figure 1 shows a sanitary napkin and Figure 2 shows a diaper each has an ink composition comprising a microencapsulated skin beneficial agent applied by print to the top sheet of the article. The articles are elongated in shape having a longitudinal front portion, a longitudinal rear portion and a center or crotch portion located therebetween. The article in Figure 1 has a fin that extends from each longitudinal side end of the article. The ink composition was printed onto the article in areas or zones by an in-line synchronized printing technique. The zones are areas printed on the fins and side portions of the article (a), in the center of the crotch portion of the article (b), the rear portion of the article (c) and the front portion of the article (d). The ink composition is printed on the wetting zone (1), on the front (2, 3, 4), on the back (5, 6) and along the longitudinal sides of the article (7, 8) and on the fins (9).
    [0050] The print that includes one or more of the skin-beneficial additives can be applied in different layers of the product. The top sheet is printed in the example above, but an intermediate layer, core or acquisition layer, or on a back sheet, glued part, packaging or silicone paper can also be printed. In more than one printed area, it is possible to have the same or different beneficial additives printed on the same product layer and also on different product layers. Printed beneficial zones can be placed within an absorption area or outside the absorption area of an article. EXAMPLES
