  • Patent number: 6893630
    Abstract: Anti-microbial products comprising an antiperspirant active and an amount of transition metal chelator sufficient to enhance the deodorancy performance of said antiperspirant active, are claimed. The transition metal chelator salt improves the anti-microbial performance of the antiperspirant active and the two components can be co-formulated. Particular products are antiperspirant deodorant compositions. Preferred chelator salts have high affinity for iron (III).

  • Patent number: 6793914
    Abstract: An anti-microbial composition employing: (i) a C1 to C4 monohydric alcohol carrier fluid, present at a level of at least 50% by weight of the total composition (excluding any volatile propellant present); (ii) an iron (III) chelator having an iron (III) binding constant of 1023 or greater; and (iii) a solubility promoter such as water: The transitional metal chelator serves as an active anti-microbial, whilst the carrier fluid-solubility promoter mixture enables the formation of a stable composition. Preferred compositions are homogeneous solutions.

  • Patent number: 6503490
    Abstract: The invention concerns the achievement of a deodorancy benefit upon the human body or upon articles worn in close proximity thereto and involves the application of an anti-microbial product comprising a transition metal chelator and a phenolic or enolic compound that is (a) a transferrin dissociation promoter that operates by aiding the reduction of iron(III) bound to transferrin to iron(II) and/or (b) an anti-oxidant comprising a tert-butylphenol group.

  • Publication number: 20010033854
    Abstract: Anti-microbial compositions for use on the outer surface of the human body or on apparel worn in close proximity thereto comprising a carrier material and a salt of a transition metal chelator comprising a transition metal chelator anion and particular organic cations. The chelator salts possess great formulation flexibility, being compatible with a wide range of other materials, and are believed to function by inhibiting the up-take of essential transition metal nutrients by microbes. Preferred chelators have high affinity for iron (III).
