Publication number: 20150089714Abstract: The invention described herein relates to a therapeutic, moisturizing coating composition for elastomeric articles which is applied directly onto the skin-contacting surface of the article as part of the manufacturing process. The coating composition is thermally stable and subsequently hydrates when contacted with a moisturized skin surface to convert into a liquid “lotion” form during wearing of the article. The coating composition provides therapeutic benefits to the wearer's skin as a result of wearing the article, such as improved skin moisturization, softness of feel, improved skin elasticity and firmness, and reduced redness and irritation. The invention is particularly useful in medical gloves, including examination and surgical gloves.Type: ApplicationFiled: August 7, 2014Publication date: April 2, 2015Applicant: ALLEGIANCE CORPORATIONInventors: SHIPING WANG, Yun-Siung Tony Yeh, James Owens, Wei Cheong Wong
