A carbonaceous adsorbent to be used for the removal of a pyrogen dissolved in water is disclosed. The adsorbent is obtained by carbonizing porous beads of a cross-linked polymer. This adsorbent is favorably used for the removal of endotoxin in the production of pure water from deionized water resulting from the treatment with ion-exchange resins.

A carbonaceous absorbent to be used for the removal of a pyrogen dissolved in water is disclosed. The absorbent is obtained by carbonizing porous beads of a cross-linked polymer. This absorbent is favorably used for the removal of endotoxin in the production of pure water from deionized water resulting from the treatment with iron-exchange resins.

This detergent composition is superior in solubility, detergency, and sudsing on account of the synergistic effect of the two types of different components. This detergent composition exhibits high detergency in both soft water and hard water, and is mild to the skin and hair. ##STR1## (where RCO denotes an aliphatic acyl group of carbon number 8 to 22.).
