  • Publication number: 20140294944
    Abstract: There is provided a composition for the delivery of oxygen having microencapsulated peroxide and microencapsulated catalyst that liberate oxygen upon sufficient contact with each. The components may be stored separately or together until use. Upon mixing, oxygen is liberated. The composition can be used for wound healing or for cosmetic applications to deliver oxygen to the skin to help skin elasticity and retard the effects of aging.

  • Patent number: 8603281
    Abstract: An elastic composite formed from a lightweight nonwoven facing that has a low degree of strength in the cross-machine direction (“CD”) is provided. Through selective control over certain parameters of the materials employed in the composite and the formation process, the present inventors have discovered that such low strength and lightweight facings may be readily laminated to an elastic film without significantly damaging their integrity. For example, in one embodiment, the elastic film may possess a multi-layered construction that includes an elastomeric elastic layer positioned adjacent to a strength-enhancing thermoplastic layer. The polymer content and thickness of the thermoplastic layer are generally selected to impart additional strength and integrity to the film. Likewise, the polymer content of the elastic layer may also be selected so that the film possesses a sufficient tack for adhering to the facing.
