Claims27
A composition for controlling malodor on a substrate comprising:
- a. from about 0.05% to about 10% of a hydrophobic nanozeolite having a silica to alumina molar ratio of at least 10:1;
- b. from about 90% to about 99.95% of a compatible carrier;
- and
- c. optionally additional ingredients selected from the group consisting of surfactants, perfumes, preservatives, anti-microbials, de-foaming agents, antifoaming agents, bacteriocides, fungicides, antistatic agents, insect and moth repellents, colorants, bluing agents, antioxidants and mixtures thereof.
A laundry detergent composition for controlling malodor on a substrate comprising:
- a. from about 0.1% to about 50% of a hydrophobic nanozeolite having a silica to alumina molar ratio of at least 10:1;
- and
- b. a balance of conventional detergent ingredients selected from the group consisting of surfactants, builders, chelants, brighteners, bleaching agents, enzymes, soil release polymers, dye transfer inhibitors, fillers, perfumes and mixtures thereof.
A method for removing malodor from a porous substrate, the method comprising the steps of
- (A) applying to said substrate a composition comprising:
- (i) from about 0.05% to about 10% by weight of a hydrophobic nanozeolite having a silica to alumina molar ratio of at least 10:1:
- (ii) from about 90% to about 99.95% by weight of a compatible carrier;
- and
- (iii) optionally additional ingredients selected from the group consisting of surfactants, perfumes, preservatives, anti-microbial, de-foaming agents, antifoaming agents, bacteriocides, fungicides, antistatic agents, insect and moth repellents, colorants, bluing agents, antioxidants and mixtures thereof;
- and
- (B) allowing the substrate to dry.
An article of manufacture comprising:
- (a) a spray bottle;
- and
- (b) a composition comprising:
- (i) from about 0.05% to about 10% by weight of a hydrophobic nanozeolite having a silica to alumina molar ratio of at least 10:1;
- (ii) from about 90% to about 99.95% by weight of a liquid carrier;
- and
- (iii) optionally additional ingredients selected from the group consisting of surfactants, perfumes, preservatives, anti-microbials, de-foaming agents, antifoaming agents, bacteriocides, fungicides, antistatic agents, insect and moth repellents, colorants, bluing agents, antioxidants and mixtures thereof.
An article of manufacture comprising:
- (a) a spray bottle;
- (b) a composition comprising:
- (i) from about 0.05% to about 10% by weight of a hydrophobic nanozeolite having a silica to alumina molar ratio of at least 10:1;
- (ii) from about 90% to about 99.95% by weight of a liquid carrier;
- and
- (iii) optionally additional ingredients selected from the group consisting of surfactants, perfumes, preservatives, anti-microbials, de-foaming agents, antifoaming agents, bacteriocides, fungicides, antistatic agents, insect and moth repellent, colorants, bluing agents, antioxidants and mixtures thereof;
- and
- (c) a set of instructions in association with said spray bottle, detailing use of the composition in an amount effective to provide reduction in odors on a porous substrate.
