Self-building laundry detergents are organic polyamine amides, which contain a plurality of carboxylate radicals and an amide ester. These compounds are useful individually as detergents or as components in detergent compositions.

Self-building detergents

A toning composition which employs one or more of the propylene and butylene oxide-based glycol ethers with propylene glycol for removing sebum from the skin of a user without stinging and without dissolving and removing to any significant degree the intercellular lipids critical to the retention of moisture in the skin.

Toning composition and process of using

The invention relates to novel O,O'-, O,S'- or S,S'-dithiodialkylene-bis(mono- or dihydrocarbyl carbamothioates) and S,S'-dithiodialkylene-bis(mono- or dihydrocarbyl carbamodithioate). The novel compounds of this invention are useful as collectors in the froth flotation of sulfide mineral ores.

Curable compositions

A golf club, particularly a putter, has a unitary body including forward and rearward generally triangular and approximately planar panels merging at their apices with an upright socket adapted to receive a club shank. At their intermediate portions the forward and rearward panels are spaced apart, and at their bases the panels merge with the forward and rearward transverse margins of a ground panel substantially square in plan in a plane normal to the socket axis. The upper face of the ground panel has an upstanding, massive hump. One, or preferably both, of the side margins of the ground panel forms a substantially upright impact face.
