This invention relates to methods and compositions for materials having a non-leaching coating that has antimicrobial properties. The coating is applied to substrates such as gauze-type wound dressings. Covalent, non-leaching, non-hydrolyzable bonds are formed between the substrate and the polymer molecules that form the coating. A high concentration of anti-microbial groups on multi-length polymer chains and relatively long average chain lengths, contribute to an absorbent or superabsorbent surface with a high level antimicrobial effect.

Materials with covalently-bonded, nonleachable, polymeric antimicrobial surfaces

Absorbent dressings, including highly-absorbent dressings having antimicrobial polymer attached thereto via non-siloxane bonds are disclosed. Bandages (i.e. wound dressing), sanitary napkins and the like are useful applications for the intrinsically bactericidal absorbent dressings whose method of manufacture and use are disclosed and claimed.

Intrinsically bactericidal absorbent dressing and method of fabrication

The cosmetic topical formulation of this invention is directed toward diminishing skin wrinkling, fine line, improving skin tone, and combinations thereof. Preferably, the topical formulation contains a matrix metalloproteinase inhibitor, MMPI, and advantageously includes a natural estrogen, e.g., a true estrogen compound, such as 17-beta estradiol, or an estrogen-like steroid, (such as various phytoestrogens found in herbal preparations), as opposed to a synthetic estrogen. Other forms of the cosmetic topical formulation of this invention include combinations of synthetic estrogen and MMP inhibitor. Exemplary synthetic estrogens include, but are not limited to, ethinyl estradiol and clomiphine citrate. The cosmetic topical formulation is safe and effective diminishing wrinkling, and improving skin tone. Certain compositions of this invention are useful for minimizing photodamage to skin, while in other embodiments, the composition according to this invention is useful to prevent or minimize the adverse effects on skin induced by cigarette smoking.
