ABSTRACT:
A stearate-matrix, pre-spotter composition in solid, stick form to be applied by direct contact to stained areas of fabric, thereby transferring the composition to the stained areas of the fabric. The composition includes an alkyl aromatic sulfonic acid and/or sulfonate, at least one nonionic surfactant and an enzyme uniformly dispersed throughout a semi-hard stearate matrix. The composition optimizes the pH to promote enzyme action, while simultaneously achieving a satisfactory drop point for shipping and warehousing. Hardness and transferability are achieved at a low pH level that was previously not thought to be possible without the addition of various salts.
