A wetness indicating composition can include a mixing solvent including water and a water-miscible volatile organic solvent. The wetness indicating composition can also include an amphiphilic polydiacetylene and a hydrophobic binder. In some embodiments, the wetness indicating composition can be applied to a substrate and serve as a wetness indicator for an absorbent article.

An absorbent article having a topsheet, a backsheet, an absorbent core disposed at least partially between the topsheet and the backsheet, and a wetness indicating composition is provided. The wetness indicating composition includes a colorant and a colorant fastener. The colorant has a first color state, wherein the first color state is associated with a first state of the wetness indicating composition. The colorant has a second, different color state, wherein the second color state is associated with a second state of the wetness indicating composition. The wetness indicating composition is disposed on the absorbent article in a plurality of discrete graphics, wherein each of the plurality of discrete graphics has an area of between about 0.02 cm.sup.2 and about 25 cm.sup.2.

Described are systems and methods which can be used to indicate the period of time elapsed since the occurrence of a triggering event. More particularly, this application relates to systems and methods which can be used to visually indicate the time period elapsed since an article has been removed from its packaging. The system can include an indicator disposed on or within the article and a trigger disposed within the receptacle and in contact with the indicator. The article may be enclosed within a sealable receptacle of the package. The indicator is responsive to a change in a concentration of the trigger in contact with the indicator.

A polymer composition comprising an organic polymer and a mica containing effect pigment, e.g., a pearlescent pigment comprising mica, well suited for producing molded articles, in particular, for molding articles comprising thin sections and or delicate features, such as a hollow interior defined by a thin wall or structural features susceptible to tear or other damage and the like, is provided as are a method for preparing molded articles comprising the polymer composition and articles comprising the polymer composition, including, for example, an article used to deliver a medical or personal care component such as a tampon applicator, and a method for preparing molded articles comprising the polymer composition. Optionally, articles of the present disclosure have a varying translucency or opacity about a dimension of the article.

A product for monitoring the condition of a wound comprises: (a) a sample application zone; (b) a reaction zone downstream of the sample application zone comprising protease-sensitive polymers; (c) coloured particles; and (d) a viewing zone downstream of the sample application zone and reaction zone. The sample application zone transmits fluid towards the viewing zone. Cleavage of the polymers by protease activity present in applied wound fluid results in carriage of the coloured particles with the wound fluid to the viewing zone thereby providing a visual indication of protease activity in the viewing zone. A product for monitoring the condition of a wound comprises a matrix that absorbs wound fluid. The matrix comprises cross-linked and protease-sensitive polymers forming a reaction zone on/in the matrix, and, coloured particles. The arrangement of the polymers and coloured particles is such that cleavage of the polymers by protease activity present in the wound fluid results in transport of the coloured particles along/through the matrix to provide a visual indication of protease activity in the wound fluid. Companion products, uses, kits and methods of monitoring the condition of a wound are also provided.

The disclosed technology relates to materials for the detection of wounds, e.g., chronic wounds or infected wounds, including compositions, substrates, kits, dressing materials, and articles, and systems containing such compounds. The disclosed technology further relates to methods of using these compositions, kits and systems in the diagnosis and/or detection of chronic or infected wounds based measurement of pH. Additional disclosure relates to methods of characterizing wounds based on pH of wounds or wound fluids and using such information to treat, manage, and follow-up patients suffering from chronic or infected wounds.

Provided herein are fabric materials and debridement devices comprising gel-forming hydrofibres for disrupting a biofilm, loosening, or sequestering unwanted materials from wounds, and uses thereof. In particular, debridement and detection devices for selective and atraumatic removal of unwanted tissues and for detection of a wound infection are provided.
