Description

EXAMPLES

(1) Example compositions of lavatory treatment compositions according to the invention were produced, and are identified on Table 1. The compositions disclosed on Table 1 demonstrate compositions according to the invention, including certain preferred embodiments of lavatory treatment compositions of the invention. In these compositions, the constituents were used as supplied from their respective suppliers. The constituents constituted may have constitute less than 100% wt. actives, or may have been supplied as constituting 100% wt. active of the named compound, as indicated in the following Tables 1 and Table 2. The identified amounts of each constituent on Table 1 are in % wt. based on the total weight of a composition of which it forms a part. To each of the compositions, deionized water was added in quantum sufficient (q.s.) in order to provide to 100% wt. of each lavatory treatment composition.

(2) The lavatory treatment compositions disclosed as E1-E12 were formed generally in accordance with the following steps:

(3) To a laboratory beaker resting upon a variable temperature controllable hotplate, which laboratory beaker was further equipped with a electrically driven stirrer was provided measured amounts of the constituents of the Part A premixture (e.g. Genapol O 200, the indicated detersive surfactant, and a portion of the organic solvent constituent), and the temperature of the contents of the beaker was raised to and regulated to 80 C.-85 C., and stirring continued under these conditions until a homogenous mixture was formed. Stirring took approximately 10-20 minutes, after which, the temperature of this homogenous, first pre-mixture was allowed to reduced to approximately to 60 C.-65 C.

(4) While the first pre-mixture was being formed, into a separate lavatory beaker resting upon a variable temperature controllable hotplate and equipped with a further electrically driven stirrer were provided measured amounts of the Part B constituents (a portion of the organic solvent constituent, and where present, fragrance and/or coloring agent) were supplied and stirring was initiated while the temperature of the contents of this further beaker was maintained at a suitable temperature, advantageously between about 10-60 C. Stirring of the contents of the second laboratory beaker continued until homogenous which formed the second pre-mixture. Thereafter, the second beaker was removed, and its contents were added, under stirring conditions at a temperature of between about 60 C.-65 C. to form a resultant homogenous mixture. Stirring continued for approximately 5-15 minutes. Thereafter, the stirrer was removed, and to the laboratory beaker was added a measured aliquot of the deionized water (Part C) which is approximately room temperature and a manual stirring rod or paddle was used. It was observed that the onset of gelling within this laboratory beaker was nearly instantaneous, and the formation of a firm gel had begun in as little as 5-10 seconds after the introduction of the water. Subsequently, the manual stirring rod or paddle was removed, and set aside. The contents of the laboratory beaker was allowed to rest, overnight (approx. 12 hours) at room temperature, on a laboratory tabletop, in order to allow for the gel to fully set.

(5) The lavatory treatment compositions according to E13-E25 of Table 1 were produced in accordance with the following general protocol. The first premix identified as Part A of Table 1 was formed by adding to a clean container (e.g., an open mouthed laboratory beaker) the adhesion promoter constituent based on a fatty alcohol polyglycol ether. The container was positioned in a combination laboratory hotplate and magnetic stirrer apparatus. The container was next heated from room temperature (approx. 20 C.), and at approx. 45 C. a magnetic stirring bar was introduced and stirring initiated, and continued until the adhesion promoter constituent reached approx. 80-90 C. to ensure the full melting of the adhesion promoter constituent had occurred. Thereafter under stirring conditions were added the remaining constituents of Part A, and stirring an heating was maintained until the contents of the container was homogenous, after which the heat source was deactivated or removed, and under continued stirring the contents of the container were allowed to cool, to 45 C.-65 C. During this time the second premix identified as Part B of Table 1 was formed in a similar manner, by mixing the constituents in a clean container, under stirring and under heating to a more moderate temperature of to approximately 55 C.-65 C., thus providing a homogenous mixture of the Part B constituents. Next, a measured amount of water, identified as Part C of Table 1, which was preferably distilled or deionized water, was heated to approx. 80 C. in a third container. When the water was sufficiently heated, the homogenous mixture of the first container and the second containers were combined, and optionally mixed, and thereafter this mixture was poured into the water of the third container and optionally mixed using a manual stirrer rod, or by a mechanical mixing means. The third container was briefly heated (approx. 2 minutes) at a low power setting (approx. 300 Watts) in a consumer grade microwave device, and thereafter was poured into one or more wide bore syringes, and allowed to rest in a quiescent state for at least 5 minutes in order to allow for the initiation of hardening and formation of a self-supporting gel. Subsequently the lavatory treatment composition was dispensed from the syringe using a mechanical press to extrude the gelled lavatory treatment compositions into a small dispensing container which contained between 3-9 grams of the gelled lavatory treatment compositions.

(6) Alternately following mixing of Part A, Part B and Part C, the resultant lavatory treatment composition may be allowed to rest in a quiescent state at room temperature until a self-supporting gel was formed. It is observed that when the resultant mixture was provided, e.g. poured, into small form, cavity, mold or container (e.g., having a volume of less than about 100 cc, the spontaneous formation of the self-supporting gel, preferably a ringing gel, occurs at a much faster rate then were the resultant mixture is allowed to rest at room temperature in a larger form, cavity, mold or container. The resultant gel may be ejected from the form, cavity, mold or container in which it had formed, and used as a lavatory treatment composition. Alternately the resultant gel may be heated, e.g, in a microwave, until it returns to a fluid form after which it can be poured again into a form, cavity, mold or container, or other process equipment, such as a nozzle or syringe from which the lavatory treatment composition may be dispensed.
