  • Patent number: 11904032
    Abstract: A wearable article, a moisturizing composition and a method for preparing a wearable article have been disclosed. The wearable article includes at least a layer of a flexible material, wherein the flexible material is an elastomeric material and an inner surface of the layer of flexible material is a coated with a coating formulation comprising 1% to 7% by weight of a moisturizing composition and 93% to 99% by weight of solvent. The moisturizing composition includes 10 to 30% by weight of at least one humectant and 1.0 to 5.4% by weight of at least one antioxidant. Thereby, the present invention reduces transepidermal water loss (TEWL) and promotes skin barrier recovery.

  • Publication number: 20220015478
    Abstract: A detachable glove comprising at least two layers that are separated by an adhesive layer, wherein the adhesive layer includes a wetting agent, a latex coagulating agent, a synthetic organic polymer and water. A chlorinated detachable bi-layered glove and a method of manufacturing thereof. A polymer coated, detachable, bi-layered glove and a method of manufacturing thereof. A method of peeling a detachable bi-layered glove wherein the method includes (i) pulling cuff area of the outer glove layer until its circumference is detached from the inner glove layer and (ii) peeling off the outer glove layer once the full circumference of the outer glove layer is detached from the inner glove layer to yield the inner glove layer for further usage.

  • Publication number: 20210147649
    Abstract: A coating composition, an elastomeric article having the coating composition and a process for making coated elastomeric articles are disclosed in the present invention. The coating composition comprises 0.5% to 11% by weight/volume of at least one cooling agent; 0.5% to 11% by weight/volume of at least one non-ionic surfactant; and water, wherein rest of the coating composition is made of water. The coated elastomeric articles prepared according to the present invention improve user's sensory experience of wearing the elastomeric articles for long durations without varying the user's hand temperature or limiting mobility of the user's hand.
