Abstract: Polysaccharide aldehydes having the formula Sacch-O-CH.sub.2 -CH.dbd.CH-CHO, Sacch-O-CH.sub.2 -C.tbd.C-CHO, ##STR1## such as starch, cellulose, and gum aldehydes, are useful for imparting wet, dry, or temporary wet strength to paper. They are prepared by a non-oxidative method which involves reacting the polysaccharide base, in the presence of alkali, with a derivatizing acetal reagent having the general structure ##STR2## and then hydrolyzing the acetal by adjusting the pH to less than 7, preferably 2-4. In the formulas, n is 1-3; R.sup.11 and R.sup.12 are independently an alkyl, aryl, aralkyl, or alkaryl group when n is 1, R.sup.11 or R.sup.12 is one of the groups when n is 2, or R.sup.11 and R.sup.12 are not present when n is 3; R.sup.13 is an alkyl group, optionally containing an ether linkage, or an aralkyl group; R.sup.14 and R.sup.15 are individually a hydrogen or a methyl group; R.sup.16, R.sup.17, and R.sup.18 are individually an alkyl group; Y.sup.

Abstract: Derivatives of carbonyl-group containing behavior modifying compounds, in which said carbonyl group has been converted to a photolabile group which regenerates the carbonyl group on exposure to radiation, are of value in various methods for the control of animal, and in particular insect, species.

Abstract: An active antioxydant containing a compound shown by structural formula ##STR1## is produced by applying an acid catalyst to sesamolin substantially in the absence of active hydrogen compounds.

Abstract: There is provided a novel benzylamine derivative of the formula I: ##STR1## wherein R.sup.1 represents a hydrogen atom or a methyl group, X represents a hydrogen atom, a methyl group or a tosyl group, and Y represents a hydrogen atom, a methyl group or ##STR2## in which R.sup.2 and R.sup.3 being identical or different from each other represent independently a lower alkyl group.

Abstract: The invention relates to a cosmetic composition for combating the greasy appearance of hair. This composition is characterized in that it contains an active product consisting of a particular polymer derived from chitosan comprising 0 to 30% by weight of units (A), 5 to 50% by weight of units (B), 30 to 90% by weight of units (C), or alternatively preferably 0 to 20% by weight of units (A), 40 to 50% by weight of units (B), 40 to 50% by weight of units (C.sub.1) below; ##STR1## The use of the composition makes it possible to delay the onset of the greasy appearance of the hair.

Abstract: The invention relates to nitrocellulose free nail lacquer compositions comprising copolymers of hydrophobic and hydrophilic monomers, in suitable carriers. The nail lacquer compositions may be applied to nails where they form a high gloss, well adhering waterproof film. A process for forming nitrocellulose free nail lacquer compositions is also provided.

Abstract: The present invention relates to a novel method of preparing D-ribose.In this method, a 1,5-di-O-alkyl derivative of D-xylofuranose is prepared; the hydroxyl groups in positions 2 and 3 are each substituted by a group which is preferably mesyl (CH.sub.3 SO.sub.2) or methyldithiocarbonyl, CH.sub.3 SC(=S); the 2,3-unsaturated derivative is prepared; and D-ribose is finally obtained by cis-hydoxylation of the carbon-carbon double bond, followed by acid hydrolysis of the resulting 1,5-O-dialkyl derivative.

Abstract: This invention relates to novel intermediate compounds resulting from a method for forming a dihydrogen-phosphate inositol from a protected or unprotected inositol that comprises at least two vicinal trans hydroxy groups that are unprotected. This method results in each of the unprotected hydroxy groups of the inositol, which can contain from two to six unprotected hydroxy groups, being converted to a dihydrogen-phosphate group and each protected group being converted to a free hydroxy group. The method permits one to make such compounds in very few steps and in very high yields.
