Particulate laundry detergent composition comprising a detersive surfactant, carbonate and a flourescent whitening component

A solid laundry detergent composition comprising:

• (a) a detersive surfactant;
• (b) from 0 wt % to 10 wt % zeolite builder;
• (c) from 0 wt % to 10 wt % phosphate builder;
• (d) carbonate;
• and
• (e) a fluorescent whitening agent;
• wherein the composition is in free-flowing particulate form and comprises at least two separate particulate components,
• wherein the first particulate component comprises:
• (i) a detersive surfactant;
• (ii) at least 10 wt %, by weight of the first particulate component, of carbonate;
• (iii) from 0 wt % to 10 wt %, by weight of the first particulate component, of zeolite builder;
• (iv) from 0 wt % to 10 wt %, by weight of the first particulate component, of phosphate builder;
• and
• (v) from 0 wt % to less than 5 wt %, by weight of the first particulate component, of fluorescent whitening agent;
• and
• wherein the second particulate component comprises:
• (i) at least 0.20 wt %, by weight of the second particulate component, of fluorescent whitening agent;
• and
• (ii) from 0 wt % to less than 20 wt %, by weight of the second particulate component, of carbonate.
