A fluorinated organic acid compound of the formula C.sub.n F.sub.2n.sub.+1 CONRCHRCOOH, wherein each R is independently selected from H or an alkyl radical of one to eight carbon atoms and n is an integer of six to 18, is added to a dispersion containing a pigment, a bonding agent and a dispersing agent such as sodium alginate to obtain improved dye compositions.

Carotenoid compositions dispersed in a hydrophilic, organic colloid such as gelatin which is distributed on the particles of a pulverulent carrier material such as starch which has a lipophilic surface.

Compositions useful for imparting fluorescent properties to surfaces comprising at least one compound of the formula: ##SPC1## Wherein R.sup.1 and R.sup.2 represent individually alkyl of 1-18 carbons; R.sup.3 and R.sup.4 each represent a monocyclic or bicyclic aryl radical.

The corrosivity toward copper of lubricating oils containing a polyvalent metal salt of a diester of dithiophosphoric acid is substantially reduced by incorporating therewith a zinc dialkyl naphthalene sulfonate and a basic alkaline earth metal petroleum sulfonate.

An antibiotic composition having as essential components (A) a broad spectrum cephalosporin antibiotic subject to degradation by a .beta.-lactamase and (B) a cephalosporin antibiotic resistance to degradation by the .beta.-lactamase whereby the broad spectrum antibiotic is protected against such degradation.

The subject matter of the present application relates to polyurethane compositions. As disclosed herein, the polyurethane compositions are prepared by heating a composition which comprises polyoxyalkylene polyol, organic polyisocyanate, alkoxyalkylamino compound, acid catalyst, and metallo-organic catalyst.

The lubrication characteristics of alkylmethylpolysiloxanes in which the alkyl radical contains from six-18 carbon atoms are improved by the addition of from about 0.1 to 3 weight percent dodecenyl succinic acid anhydride.
