Abstract: Excellent adhesion to subsequently applied paint or elastomer is obtained by coating a metal substrate with a phosphate conversion coating by contact with a liquid phosphating solution that contains zinc cations, phosphate anions, and at least one adhesion promoter selected from (i) film-forming organic substances, (ii) polymers of vinyl phenols modified by substitution of substituted aminomethyl moieties on their aromatic rings, (iii) inorganic oxides of one of the elements silicon, aluminum, titanium, and zirconium. Preferably, the phosphating solution also contains manganese and nickel cations and either iron cations or hydroxylamine. If adhesion to paint is desired, the adhesion promoter preferably is an acrylic film-forming substance, while if adhesion to elastomers is desired, the adhesion promoter preferably is a polymer of vinyl phenol and the phosphating solution preferably also contains calcium cations.

Abstract: Autodeposited coatings useful for protecting metal surfaces and in production of rubber-to-metal composites are obtained by curing adducts based on epoxy resins which are adhered to the metal surface. One or more epoxy resins, such as for example, the combination of a diglycidyl ether of bisphenol A and a flexibilizing epoxy resin, may be prereacted to form an adduct of higher average molecular weight than the starting epoxy resins. Said adduct may then be dispersed in water, with the resulting dispersion being used in an autodeposition bath composition.

Abstract: This invention relates to a jointing compound of an acrylate/acrylonitrile copolymer containing 2 to 8 carbon atoms in the alcohol component as binder and fatty compounds as plasticizer and also fillers and auxiliaries. Epoxystearic acid methyl ester in particular may be used as the fatty compound while a butyl acrylate/acrylonitrile copolymer in particular may be used as the acrylate/acrylonitrile copolymer. The combination of the two substances results in jointing compounds characterized by a dramatic improvement in elasticity (resilience). Accordingly, they are particularly suitable for substrates with different coefficients of thermal expansion.

Abstract: A hybrid dye is provided that is useful for coloring keratin fibers and skin. The hybrid dye has the structure X-S-Y, where X is derived from a substantive dye, Y is derived from an oxidation dye precursor or a melanin precursor, and S is a direct bond or spacer group. The present invention also provides a composition for coloring keratin fibers that contains the hybrid dye.

Abstract: An encapsulated active substance for a manual detergent for hard surfaces comprises an essentially anhydrous active substance with at least one surfactant and at least one liquid polymer carrier encapsulated in a water-soluble or water-dispersible capsule, the active substance containing: less than 25 wt. % of carrier; at least one unbranched or branched, acryclic or cyclic, saturated or unsaturated alcohol with 1 to 10 carbon atoms and one or two primary, secondary or tertiary hydroxy groups and a carbon chain optionally having one or more —O— groups; or being free of glycerol. The encapsulated active substance can be used as a manual detergent for hard surfaces.

Abstract: A device for dispensing solid material from a tube having a longitudinally displaceable internal piston moved by an externally operated spindle threading through the piston. At its base the spindle has a narrowed, non-threaded region, such that when the piston is fully withdrawn into the tube, the threads of the spindle and piston slip if the spindle continues to be rotated. To prevent the piston threads from completely disengaging the spindle threads, the spindle's non-threaded region is shorter than the piston's internal threads. In this way, the spindle will not break even if it continues to be rotated after the piston is fully withdrawn into the tube, yet it readily engages the piston threads when turned in the opposite direction to displace the piston towards the dispensing end of the tube. Thus the device as a whole remains reliably usable.
Abstract: The invention relates to a low-viscosity hotmelt adhesive containing A) at least one hydrocarbon resin solid at 20° C. with a softening temperature of 70 to 140° C., B) at least one oil with an average molecular weight of >500 and preferably C) a styrene block copolymer. The new hotmelt adhesive is distinguished by a melt viscosity of essentially only 500 to 3200 mPas at 150° C. for a softening temperature of 60 to 115° C. It is preferably used in the field of hygiene for bonding films, nonwovens and/or shaped articles of cellulose derivatives, being distinguished by particular resistance to dermatologically compatible coatings.

Abstract: A dispenser is provided for dispensing a flowable product from a container. The dispenser includes a roller applicator having a roller housing and roller rotatably mounted on the roller housing. The dispenser also includes an openable closure and sealing elements. The closure pivots relative to the roller to provide an open position in which the roller is uncovered and a closed position in which the roller is covered by the closure to the outside. The sealing elements are located between the roller and the roller housing and are activated by turning the closure into the closed position.
Abstract: A process for coating laundry detergent or cleaning product tablets that contain builder(s) and also, if desired, further laundry detergent and cleaning product ingredients, by transporting the tablets on a conveyor belt provided with a multiplicity of apertures and forcing coating material through the conveyor belt apertures from below with a force such that the coating material forced over the conveying plane forms a surge through which the tablets are transported.
Abstract: The toothbrush consists of a brush head with bunches of bristles (2, 3, 4) arranged in a longitudinal bristle bed (1) and a handle (6), which is connected to the bristle bed (1) by a connecting part (5). The length of the bunches of bristles (3, 4) varies in the longitudinal direction of the bristle bed (1) in a wave shape. The first bunches of bristles (2) are situated at the two outer sides of the bristle bed (1), have split bristle ends and are of essentially the same length. The second bunches of bristles (3, 4), whose length varies in the longitudinal direction of the bristle bed (1), are situated between the two outer sides of the bristle bed (1). The inventive toothbrush has an improved cleaning action, especially for interdental spaces but also for the gingival line.

Abstract: A film of a polymer or polymer precursor such as an epoxy resin is autodeposited on an active metal surface and then used to form an adhesive bond directly between the metal surface and the surface of a rubber substrate. Excellent adhesion of the metal to the rubber is obtained without the need to either phosphate the metal surface or use a primer or adhesive other than the autodeposited coating.
