Abstract: Amino resins that contain more free formaldehyde than is desirable for health and/or pollution reasons can be treated with a mixture of diketo reagents (or their nitrogen analogs) and other compounds containing amino moieties to reduce the free formaldehyde content while not diminishing, and in some cases even enhancing, the ability of the resins to function according to their normal uses. The invention is especially useful for melamine-formaldehyde resin dispersions useful to detackify paint.

Abstract: A refill cartridge for a stick product dispenser, for stick products including adhesive sticks, lipsticks, release agent sticks, shaving soap sticks, coloring sticks, and so forth, is provided by molding the stick product material to have a shape substantially the same as the internal shape of the associated dispenser casing or holder, and to fill the free internal volume of the holder. When the stick product originally within the dispenser is used, the refill cartridge is partially inserted into an open end of the empty dispenser holder, and the cartridge is either pushed or drawn into the dispenser, for refilling the same with the desired stick product, and permitting nonconsumable portions of the stick product dispenser to be repeatedly reused via such refilling.

Abstract: A mutant fungal strain, namely G. candidum NRRL Y-552, mutant known as Henkel 9-2-3-9 produces a lipase called "UNLipase" providing a selectivity of 25:1 for oleic acid over palmitic acid by the assay procedure employed. UNLipase has a temperature range of operation of between 0 and 40 degrees Celsius (and no activity over 55 degrees Celsius). The optimum pH ranges are between 7.5 and 8.5. Magnesium cations increase activity, whereas calcium cations are inhibitory. The molecular weight of the protein appears to be 65 kDa by size exclusion chromatography. UNLipase shows a high degree of selectivity for hydrolysis, esterification and transesterification.

Abstract: The stability in storage and flowability of liquid water-based alkyl glycoside preparations of relatively low concentration were to be improved and their handling under in-use conditions was to be facilitated by an increase in viscosity with very small quantities of non-alkyl-glycoside active substance. This was achieved by gel-form aqueous mixtures consisting essentially of 2% by weight to 15% by weight of an alkyl glycoside corresponding to the formula R.sup.1 --O(G).sub.n, in which R.sup.1 is an alkyl radical containing 8 to 22 C atoms, G is a glycose unit and n is a number of 1 to 10, 0.05% by weight to 2% by weight of an anionic surfactant of the sulfate or sulfonate type, the ratio by weight of alkyl glycoside to sulfate and/or sulfonate being 40:1 to 5:1, and 83% by weight to 97.95% by weight water or a mixture of water with a water-miscible organic solvent.

Abstract: A bath for treating metal surfaces for the formation thereon of composite films for the cold working of metal advantageously comprises an otherwise conventional conversion coating bath that also contains organic cationic polymer having at least 1 cationic nitrogen atom per molecule and having a molecular weight of 1,000 to 1,000,000, or a salt of such a polymer. Major improvements in the lubrication properties, particularly in the seizure resistance, can be achieved by applying out a conventional lubrication treatment on such a composite film. Specifically, practical operating limits in metal cold working, e.g., the working degree or ratio, working speed, tool life, and the like, can be increased in a single step. This is useful in terms of improving productivity, product stability, cost reduction, and the like.
