  • Patent number: 6051544
    Abstract: Granular secondary alkanesulfonate, essentially comprising finely divided, solid sec. alkanesulfonate and an additive. This granular sec. alkanesulfonate is obtained by grinding and mixing coarse sec. alkanesulfonate with an additive. The resulting alkanesulfonate can be used in solid detergent and cleaning product compositions or directly for producing extrudates, pressed articles or compacts.
