Abstract
Liquid alkyl lactam bleach activators are intimately mixed with a water-soluble surfactant and a thickener to form a bleach activator particle with good solubility, which perhydrolyzes well, and which is non-sticky and free flowing. Optionally, but preferably, the particles will further comprise binders and filler materials. Novel activator compositions comprising polyhydroxy fatty acid amides plus lactam activators are disclosed.
