Abstract
Solid alkali metal benzyl oxide compositions providing flowable solids, namely flowable powders and flowable granulates, and solid compositions containing the alkali metal benzyl oxide compositions in combination with additional components are disclosed. Methods of making the solid compositions and using the solid compositions are also provided. The solid compositions are particularly useful for making solid cleaning compositions, including degreasing compositions, that beneficially are PPE-free providing safety improvements over liquid formulations.
Claims19
A solid composition comprising:
- an alkali metal benzyl oxide;
- a sulfonate carrier;
- and
- a non-hygroscopic solid acid;
- wherein the solid is tablet, block, powder or granulate, wherein the solid is a dimensionally stable solid or a flowable solid, and wherein the solid does not require personal protective equipment (PPE) for handling.
A method of making a solid composition comprising:
- combining either (i) an alkali metal hydroxide, benzyl alcohol and a sulfonate carrier to generate in situ a solid composition, or (ii) a premix comprising alkali metal benzyl oxide and a sulfonate carrier with a non-hygroscopic solid acid,
- wherein the molar ratio of alkali metal hydroxide to benzyl alcohol is at least about 2:1 to about 5:1, or preferably from about 2:1 to about 4:1, and
- adding a non-hygroscopic solid acid to generate the solid composition, wherein the solid is tablet, block, powder, or granulate and wherein the solid is a dimensionally stable solid or a flowable solid.
