Abstract: A topical composition for skin treatment comprising about 60.001% to 1% by weight of a retinoid solubilizer and/or stabilized with preferably about 0.1% to about 50% by weight of a diester or polyester of a naphthalene dicarboxylic acid having compound formula (I), (II), (III) or mixtures: wherein R1 is an alkyl group, straight chain or branched, having 1 to 22 carbon atoms; wherein each R1, same or different, is an alkyl group having 1 to 22 carbon atoms, a diol having the structure HO—R2—OH, or a polyglycol having the structure HO—R3—(—O—R2—)m—OH wherein R2 and R3, same or different, are each an alkylene group, straight chain or branched, having 1 to 6 carbon atoms, and wherein m and n are each 1 to about 100, or a mixture thereof.

Abstract: A composition containing a diester of a naphthalene dicarboxylic acid having compound formula (I) for photochemically stabilizing dibenzoylmethane derivatives, absorbing UV radiation, imparting gloss and for stabilizing natural hair color and hair dyes against fading, and which can be used to increase the emolliency and sunscreen protection factor (SPF) of cosmetic formulations and for filtering out ultraviolet radiation from human skin: wherein R1 is has the formula (II) wherein k is 1 to 13, preferably 1 to 6, most preferably 1, and R2, same or different, is selected from the group consisting of a compound of formula (II) wherein k is 1 to 13, preferably 1 to 6, most preferably 1, and an alkyl group, straight chain or branched, having 1 to 22 carbon atoms, and mixtures thereof. These diesters of formula (I) are quite effective in stabilizing the dibenzoylmethane derivative UV-A filter compounds making them more effective, and effective for longer periods of time.

Abstract: The invention relates to new furfurylthioalkanes of the formula ##STR1## wherein n can be zero or 1R represents the methyl or ethyl radical if n is 0, and represents hydrogen or the methyl radical if n is 1, andR' represents methyl or ethyl,a process for their preparation and their use as aroma substances.

Abstract: Dimethylfuryl-dihydro-1,3,5-dithiazines are useful flavorings having low taste threshold values. They impart a coffee or mocha taste, in particular to drinks, confectionery and bakery products.

Abstract: The invention relates to new thio-alkanones of the formula ##STR1## in which X represents an oxygen or sulphur atom,R.sub.1 represents hydrogen or a C.sub.1 -C.sub.2 -alkyl group and the broken lines represent a single bond or no bond,to a process for their preparation and their use as flavorings.

Abstract: Disclosed is an improved method for preparing a particulate citric acid or an alkali metal alkaline earth metal salt thereof. The method involves spray granulating citric acid or a salt thereof from its partially purified fermentation broth to form granules which are freer flowing and less inclined to fracture than is citric acid or its salts prepared by crystallization techniques which properties render the material prepared by the present method suitable for handling in bulk.

Abstract: A process for the preparation of pure 2-hydroxybenzyl alcohol, pure 4-hydroxybenzyl alcohol or a mixture of both hydroxybenzyl alcohols by reacting phenol and formaldehyde in the presence of a basic catalyst and subjecting the resulting reaction mixture to an at least 2-stage countercurrent extraction in a solvent system of water/organic solvent which is water-immiscible or water-miscible only to a limited extent.
