  • Publication number: 20180064842
    Abstract: A substrate includes a double-network polymer system including a cross-linked, covalently-bonded polymer and a reversible, partially ionicly-bonded polymer, wherein the substrate has a moisture level less than or equal to 15 percent of the total weight of the substrate, and wherein the substrate includes a latent retractive force. A method for manufacturing a substrate includes producing a double-network hydrogel including a cross-linked, covalently-bonded polymer and a reversible, ionicly-bonded polymer; elongating by force the double-network hydrogel in at least one direction; dehydrating while still elongated the double-network hydrogel to form a substantially-dehydrated double-network polymer system; and releasing the force to produce the substrate.

  • Patent number: 9895094
    Abstract: A lateral flow device for testing a bodily fluid, such as urine, blood, mucous, saliva, etc., is provided. The lateral flow device is configured to be attached to an absorbent article via an attachment mechanism located on the lateral flow device or the absorbent article. The lateral flow device includes a chromatographic medium (e.g., porous membrane) that defines a detection zone that provides a signal indicative of the presence or absence of the analyte. The device may also include a control zone that provides a signal indicative of whether a sufficient amount of bodily fluid has been provided and tested. Regardless of its specific configuration, the lateral flow device is configured to be attached onto the absorbent article to provide a user or caregiver with rapid information about a health condition. For example, the device may be attached onto a diaper to provide information about the presence of enzymes or other compounds often encountered with a patient having a urinary tract infection.

  • Patent number: 9585826
    Abstract: A triggerable composition for two-stage, controlled release of a functional active chemical includes an encapsulation material for encapsulating a betaine ester or betaine ester derivative including a functional active. The encapsulation material is triggerable to release the betaine ester or betaine ester derivative at a first stage upon the occurrence with an environmental stimulus, such as a pH change, an enzymatic change, and a temperature change. The betaine ester or betaine ester derivative of a functional active with at least one hydroxyl group releases the functional active through a hydrolysis reaction upon contact with an aqueous medium.

  • Patent number: 9555147
    Abstract: The invention describes a color-developing composition that contains at least four major components: (1) a leuco dye or a combination of leuco dyes, (2) an electron-withdrawing color-developer agent or a combination of color-developers that can form colored complexes with the leuco dyes, (3) a separator or combination of separators that when present in sufficient amounts, can prevent the formation of the colored complexes between the color-developer and leuco dyes, all contained within (4) an encapsulation matrix that includes at least one film-forming and one aqueous-insoluble polymer. All of the foregoing components are dissolved together in a volatile organic solvent medium to form a homogeneous solution that can be applied as an ink on substrates, which can be incorporated as part of absorbent articles or personal care products.

  • Patent number: 9084838
    Abstract: A feminine care absorbent article (e.g., feminine care pad, sanitary napkin, tampon, etc.) is provided that employs a synergistic combination of an antimicrobial composition for inhibiting thegrowth of microorganisms (e.g., bacteria, protozoa, yeast, fungi, etc.) and a pH sensor for signaling to the user when the antimicrobial composition is no longer operating at its full capacity. In this manner, the user can initially wear the article without fear of infection. After a certain period of time, the user can visually inspect the color of the pH sensor to obtain an indication of whether the antimicrobial composition is still active and effective in inhibiting microorganism growth, or whether it is time to replace or remove the article.
