A sanitary napkin is disclosed as a form of disposable absorbent article. It has an absorbent core and a hydrophobic topsheet that has an upper side that is to be worn against a user's body. The topsheet is selected from a group of nonwoven topsheets and apertured film topsheets. A trace amount of a fibrous superabsorbent material, in the range of 0.30 and 3.5 grams of superabsorbent material per square meter, is provided in a fibrous matrix in a secondary topsheet that is in intimate contact with the lower side of the topsheet. The fibrous matrix is made by airlaying the superabsorbent material with cellulose and bi-component fiber onto a non-woven carrier.

Disposable absorbent article

A disposable absorbent article having a durable hydrophilic substantially liquid pervious acquisition layer. The acquisition layer includes an acquisition layer substrate and a hydrophilicity boosting composition coated on the acquisition layer substrate. The hydrophilicity boosting composition includes a hydrophilicity boosting amount of nanoparticles having a particle size of from about 1 nanometer to about 750 nanometers.

Disposable absorbent article comprising a durable hydrophilic acquisition layer

A disposable absorbent article having a durable hydrophilic substantially liquid pervious topsheet. The topsheet includes a topsheet substrate and a hydrophilicity boosting composition coated on the topsheet substrate. The hydrophilicity boosting composition includes a hydrophilicity boosting amount of nanoparticles having a particle size of from about 1 nanometer to about 750 nanometers.

Disposable absorbent article comprising a durable hydrophilic topsheet

The present invention relates to an absorbent article having a stable skin care composition disposed on its skin-contacting surface. The skin care composition is readily transferable to the skin via normal contact, wearer motion, and/or body heat. Importantly, the skin care composition contains at least one skin care ingredient imparting visible skin benefits to the skin upon transfer to the skin and at least one theological agent for stabilizing the composition such that agglomeration, stratification and/or settling of the composition are minimized. The present invention also relates to a process for making the absorbent articles having a stable skin care composition disposed thereon.

Absorbent article having a stable skin care composition

A disposable absorbent article having a durable hydrophilic substantially liquid pervious core wrap surrounding a storage layer. The core wrap has a hydrophilicity boosting composition coated on a core wrap substrate. The hydrophilicity boosting composition includes a hydrophilicity boosting amount nanoparticles having a particle size of from about 1 nanometer to about 750 nanometers.

Disposable absorbent article comprising a durable hydrophilic core wrap

The present invention relates to an absorbent article having a stable skin care composition disposed on its skin-contacting surface. The skin care composition is readily transferable to the skin via normal contact, wearer motion, and/or body heat. Importantly, the skin care composition contains at least one skin care ingredient imparting visible skin benefits to the skin upon transfer to the skin and at least one rheological agent for stabilizing the composition such that agglomeration, stratification and/or settling of the composition are minimized. The present invention also relates to a process for making the absorbent articles having a stable skin care composition disposed thereon.

Process for applying a stable skin care composition to a substrate

Coating compositions, methods and articles of manufacture comprising a nanoparticle system employing same to impart surface modifying benefits for all types of soft surfaces, and in some cases, hard surfaces, are disclosed. In some embodiments, dispersement of nanoparticles in a suitable carrier medium allows for the creation of coating compositions, methods and articles of manufacture that create multi-use benefits to the modified surfaces. These surface modifications can produce long lasting or semi-permanent multi-use benefits that, in some embodiments, may include at least one of the following improved surface properties: cleaning, wettability, liquid strike-through, comfort, stain resistance, soil removal, malodor control, modification of surface friction, reduced damage to abrasion and color enhancement, relative to the surfaces unmodified with such nanoparticle systems.

Method of hydrophilizing materials

The present invention relates to methods for inkjet printing of nanoparticle system for types of soft surfaces, and in some cases, hard surfaces.

Method of applying nanoparticles

The present invention relates to disposable thermal packs comprising a unified structure having at least one continuous layer of a semirigid material which softens when heated. The thermal packs also comprise a plurality of individual heat cells, which typically comprise an exothermic composition, spaced apart and fixed throughout the unified structure. The material of the continuous layer or layers provide sufficient rigidity to maintain structural support of the heat cells, to prevent unacceptable stretching of structures of the continuous layer or layers during processing or use of the thermal packs, and to deter easy access to heat cell contents, while also providing good overall drape characteristics when heated. The thermal packs, when incorporated into body wraps, pads, and the like, provide efficient and effective heat coverage by having excellent conformity with various body forms.

Thermal pack having a plurality of individual heat cells

Back wrap having thermal cells

The present invention relates to disposable thermal neck wraps having one or more thermal packs comprising a unified structure having at least one continuous layer of semirigid material, which has different stiffness characteristics over a range of temperatures, and a plurality of heat cells, wherein the heat energy is applied to specific areas of the upper back, neck and shoulders. More particularly, the present invention relates to disposable thermal neck wraps having good conformity to user's upper back, neck, and shoulders which provides consistent, convenient, and comfortable heat application.

Disposable thermal neck wrap

The present invention relates to disposable thermal neck wraps having one or more thermal packs comprising a unified structure having at least one continuous layer of semirigid material, which has different stiffness characteristics over a range of temperatures, and a plurality of heat cells, wherein the heat energy is applied to specific areas of the upper back, neck and shoulders. More particularly, the present invention relates to disposable thermal neck wraps having good conformity to user's upper back, neck, and shoulders which provides consistant, convienent, and comfortable heat application.

The present invention relates to disposable thermal body pads comprising one or more thermal packs having a unified structure of at least one continuous layer of a semirigid material which softens when heated and a plurality of individual heat cells, which typically comprise an exothermic composition, spaced apart and fixedly attached across the thermal pack. The material of the continuous layer or layers provide sufficient rigidity to maintain structural support of the heat cells, to prevent unacceptable stretching of structures of the continuous layer or layers during processing or use of the thermal pads, and to ensure child resistance, while also providing good overall drape characteristics when heated. The disposable thermal body pads are intended to be attached to a user's clothing on one side and to be held directly against the user's skin on the other side, for pain relief. More particularly, the present invention relates to disposable thermal body pads having good conformity to user's body which provides consistent, convenient and comfortable heat application. Even more particularly, the present invention relates to such disposable thermal body pads intended for relieving menstural pain.
