Functionalized substrates comprising perfume microcapsules
A functionalized substrate comprising: from about 1% to about 20% of a water-dispersible and/or a water-disintegrating material comprising a cellulose by weight; from about 0.001% to about 50% of a binder material by weight; and a plurality of microcapsules encapsulating at least one functional material, wherein said plurality of microcapsules is incorporated with said functionalized substrate.
1. An article comprising:
a. a functionalized substrate comprising:
i. from about 1% to about 20% by weight of said functionalized substrate, of a cellulose derivative selected from the group consisting of a hydroxypropylmethylcellulose phthalate, a hydroxypropylmethyycellulose acetate succinate, a carboxymethylethyl cellulose, a cellulose acetate trimellitate, a cellulose acetate phthalate, and mixtures thereof;
ii. from about 0.001% to about 50% by weight of said functionalized substrate, of a binder material; and
iii. a plurality of microcapsules encapsulating at least one functional material, wherein said plurality of microcapsules is incorporated with said functionalized substrate; said functionalized substrate having a rate of dissolution in water of from about 0.1 to about 1 gram/minute at a temperature of 40° F.-50° F.
2. The article according to claim 1 , wherein the weight ratio of said at least one functional material to said cellulose derivative of from about 1:0.05 to about 1:1.
3. The article according to claim 1 , further comprising a weight ratio of said cellulose derivative to said binder material of from about 100:1 to about 1:1.
4. The article according to claim 1 , wherein said binder material comprises carboxymethyl cellulose, a carboxymethyl cellulose derivative, a guar gum, a xanthan gum, and mixtures thereof.
5. The article according to claim 1 , further comprising a water-soluble polymeric material.
6. The article according to claim 5 , wherein said water-soluble polymeric material comprises: a polyvinyl alcohols, a modified PVA; a polyvinyl pyrrolidone; a polyvinylamine; a partially hydrolyzed polyvinyl acetate; a polyalkylene oxide; a polyethylene glycol; a acrylamide; a acrylic acid; a cellulose, an alkyl cellulosic; a polyvinyl acetate; a polycarboxylic acid; a polyaminoacid or peptide; a polyamides; a polyacrylamide; a copolymer of maleic/acrylic acid; a polysaccharides; and mixtures thereof.
7. The article according to claim 1 , wherein said at least one functional material comprises a perfume.
