[0210] Embodiments of the invention are further defined in the following non-limiting examples. It should be understood that although these examples are indicative of certain embodiments of the invention, they are given by way of illustration only. From the above discussion and these Examples, one skilled in the art can ascertain the essential characteristics of this invention, and without departing from the spirit and scope of the invention, Inventions are suitable for a variety of uses and conditions. Accordingly, various modifications to the embodiments of the invention in addition to those shown and described herein will become apparent to those skilled in the art from the foregoing description. Such modifications are also intended to fall within the scope of the appended claims.
[0211] The following examples provide exemplary embodiments of solid, neutral enzymatic detergent compositions of the present application that provide improved stability and cleaning performan...
example 1
[0224] In this example, exemplary formulations according to the present application were prepared to evaluate their overall stability in bulk and powder form. Twenty-seven exemplary formulations were prepared as described in Table 2 below. Exemplary formulations have a solid matrix that maintains 10-15% of the liquid composition and results in a pH of about 8-9 in solution. Observations regarding the stability of these formulations are provided in Table 3 below.

[0232] In general, the exemplary formulations, with the exception of formulation 7, demonstrated the ability to form solid lumps and / or powders. In particular, Exemplary Formulations 1-4, 8-9, and 24-27 exhibited significantly improved stability and flow in both solid block and solid powder states.
example 2
[0234] In this example, additional exemplary formulations according to the present application were prepared to evaluate their overall stability in bulk, powder form, and when the compositions were dispensed into 10% tank solutions. Eight exemplary formulations were prepared as described in Table 4 below. Exemplary formulations have a solid matrix that holds 10-15% of the liquid composition and produces a pH of about 8-9 when dispensed into a 10% reservoir solution. The blocks were held at 122°F for four weeks and their swelling was measured periodically. The 10% tank solution was kept at room temperature (RT) and 122°F and checked for phase separation immediately and again after 24 hours. These observations are provided in Table 5 below.
