Abstract

Amine functionality-containing materials such as cationic cellulose-based compositions are coated to suppress their tendency to generate "amine odors" in an alkaline pH environment. Further provided are effervescent compositions, liquid or solid soap formulations, fabric softeners, shampoos and the like comprising such materials coated with a suitable coating composition are provided.

Claims

1. A bathing composition comprising a coated amine functionality-containing composition, which coated amine functionality-containing composition comprises 0.01-10% by weight, based on the total weight of the composition, of a cationic polymer which comprises cationic cellulose, said polymer being coated with a coating composition comprising at least one coating agent selected from the group consisting of long chain non-ionic surfactants free of amine functionalities, water-soluble polymers, waxes, oils, plant sterols, alkyl/alcohol esters and mixtures thereof.

2. The coated composition of claim 1, wherein said composition is in the form of a soap or detergent formulation.

3. A bathing composition in the form of an effervescent preparation comprising a coated amine functionality-containing composition which coated amine functionality-containing composition comprises 0.01-10% by weight, based on the total weight of the composition, of a cationic polymer, said preparation further comprising a carbonate salt, which carbonate salt, prior to use, is isolated from said amine functionality-containing composition by a coating composition comprising at least one coating agent selected from the group consisting of long chain non-ionic surfactants free of amine functionalities, water-soluble polymers, waxes, oils, plant sterols, alkyl/alcohol esters and mixtures thereof.

4. The coated composition of claim 3, wherein said coating agent is selected from the group consisting of polyethylene glycol, polypropylene glycol and mixtures thereof.

5. The coated composition of claim 3, wherein said coating agent is polyethylene glycol.

6. The coated composition of claim 3, wherein said cationic polymer is present in an amount of 0.05-5% by weight.

7. The coated composition of claim 3, wherein said cationic polymer comprises cationic cellulose.

8. The coated composition of claim 3, wherein said coated composition further comprises a colloidal material selected from the group consisting of colloidal oatmeal, flour derived from corn, wheat, soy, rice or barley, meals obtained from corn or almond, hydrophobic starch obtained from corn, wheat, rice, potato, water-insoluble gums, cellulose and mixtures thereof.

9. The coated composition of claim 8, wherein said colloidal material is coated together with said cationic polymer.

10. The coated composition of claim 3, further comprising a fragrance in an amount up to 0.70 percent, by weight.
