Filed:

Sep 28, 1981

Appl. No.:

6/306466

Inventors:

David W. Colborn - Pleasanton CA
Thomas S. Coyne - Livermore CA
Carolyn P. Emrie - Pleasanton CA
Barbara H. Munk - Berkeley CA

Assignee:

The Clorox Company - Oakland CA

International Classification:

A01K 1015
C11B 900

US Classification:

119 1

Abstract:

Most conventional animal litters develop malodors fairly quickly. An animal litter in accordance with the present invention selectively releases an odor masking component in response to agitation of the litter by an animal. The animal litter comprises absorbant particles having microcapsules affixed to exterior surfaces of at least some of the absorbant particles. The microcapsules encapsulate the odor masking component, which is released when the microcapsules are ruptured.

International Classification:

C01B 1106

US Classification:

25218725

Abstract:

This invention provides a stable, fragranced liquid hypochlorite bleach composition in which an immiscible or slightly miscible fragrance is stably dispersed in the bleach substantially without wetting the interior walls of the plastic container for the bleach. This lack of wetting is caused by using as a dispersant for the fragrance, a hydrotrope which does not wet the plastic but stably suspends the fragrance in the bleach.

US Classification:

25218726

Abstract:

This invention relates to a storage and shipping system comprising corrugated containers which house plastic vessels or bottles used to hold fragranced liquid bleaches in which the shipping and storage containers are stacked on top of one another. In the stacks in all of the shipping and storage containers except for the topmost one, the plastic vessels will share some of the vertical component of the compression load caused by the shipping and storage container directly located above a given shipping and storage container. The compression load can cause stress-cracking in the vessels or bottles if strongly wetting surfactants are used to disperse the fragrances. Surprisingly, it has been found that such stress-cracking can be essentially mitigated when an agent for dispersing the fragrance is used which does not promote stress-cracking in said vessels or bottles by substantially not wetting the interior surface of said plastic, and does not decrease the surface tension below the critical surface tension of the plastic. An exemplary agent is sodium xylene sulfonate.

US Classification:

512 2

Abstract:

This invention relates to a storage and shipping system comprising corrugated containers which house plastic vessels or bottles used to hold fragranced liquid bleaches in which the shipping and storage containers are stacked on top of one another. In the stacks, in all of the shipping and storage containers except for the topmost one, the plastic vessels will share some of the vertical component of the compression load caused by the shipping and storage container directly located above a given shipping and storage container. In a further embodiment of the invention, the problem of surface wetting of blown polyethylene bottles by certain additives in liquid bleach is recognized and addressed. In another embodiment of the invention is provided a stable fragranced bleaching composition. In a still further embodiment of this invention is provided a homogeneous fragrance preblend and a method of making thereof.
