摘要:
A process for producing micronized dispersed micro-particles and to micro-particles produced by this process. In the process a combination of a dispersion liquid, an active ingredient and a wax is passed at a temperature at which the wax is molten into a high energy micro-particle producing machine operating at a temperature at which the active ingredient and wax are kept molten and producing a composition comprising a plurality of micro-particles dispersed in said dispersion liquid by cooling said combination to a temperature below the solidification temperature of each of said micro-particles before each said micro-particle leaves said micro-particle producing assembly.
摘要:
Floor care and cleaner products which can be rapidly reconstituted in water are described. The product comprises granules having an unpacked bulk density of from about 0.3 to 0.8 g/cm.sup.3 uniformly containing an alkaline builder and an alkali-soluble film-former bonded together with a water-soluble binding agent. The alkaline builder serves the dual function of a cleaner and a solubilizing agent for the film-former component.

Disclosed are end point indicator compositions and devices containing them, particularly useful as air freshener devices, comprise compositions containing a polar indicator dye which assumes a first color or is colorless in the presence of a room temperature volatilizable solvent which is initially present in excess and a small amount of a proton donating compound. The indicator dye assumes a second color visually distinct from the first color in the presence of the proton donating compound after the majority of the solvent escapes from the remainder of the composition. Optionally, the compositions further include color change developers and/or secondary dyes to render the change to the second color, indicating attainment of the end point, more apparent to a user.

摘要:
The process of the invention for the preparation of products, in particular cellulose-containing products (1) and spaces includes the arrangement of at least one flavour and/or fragrance (3) and/or active substance, bound in a solid carrier material, in and/or at the product (1) and/or the direct proximity of the cellulose-containing product (1) and/or the space. Furthermore, means are provided for the preparation of products, in particular cellulose-containing products, and of spaces as described, as well as systems from these means and products, in particular cellulose-containing products.
摘要:
The invention relates to a method for attaching a volatizable active substance (4) to a supporting material (1) and for the controlled release of this active substance (4) into the surrounding area, during which the volatizable active substance (4) is introduced into a carrier material (2), which is solid at normal temperature and which is melted by heating, and a carrier material/active material melt S is placed in contact at least with a portion of the supporting material (1) having the normal temperature or a lower temperature whereby attaching thereto in the form of a film F, and the volatizable active substance (4) is released in a controlled manner by natural and/or artificial influence of air and/or heat from the carrier material (2) attached in the form of a film F.
