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.

Composition pré-retouche, à matrice de stéarate, sous forme de bâton solide, à appliquer par contact direct avec des zones tachées d'un tissu, en transférant ainsi la composition dans les zones tachées du tissu. La composition renferme un acide aromatique sulfonique alkylé et (ou) un sulfonate, au moins un surfactif non ionique et une enzyme uniformément dispersée à travers une matrice semi-dure de stéarate. La composition optimise le pH pour activer l'action de l'enzyme, tout en assurant un point de goutte acceptable pour le transport et l'entreposage. La dureté et la transférabilité sont réalisées à un bas pH, ce qui n'était probablement pas possible antérieurement sans addition de divers sels.
