Abstract: Provided is a mixing apparatus which can efficiently mix two fluids, for example to create emulsions, which using a relatively low energy input. This objective is met by a mixing device comprising two confronting surfaces (1, 2) having cavities (3, 4) in the surfaces, (1, 2) and wherein the two confronting surfaces are located such that a least three narrow slits (cf. 7, 8, 81) are formed to provide subsequent contraction and expansion of the flow. Especially when the apparatus is run in a static mode, only a low energy input is required, while still providing favourable mixing conditions.

Abstract: The invention provides a hair treatment composition comprising a combination of a sugar, an aliphatic amino acid and a basic amino acid. The composition is particularly suitable for the treatment of hair which is dry, damaged and/or prone to manageability problems.

Abstract: The formation of nitrosamines in cooked, cured meat products is reduced or eliminated by using certain 1, 2, 3, 4-tetrahydro-6-alkoxyquinoline compounds in the curing mixtures or to treat the cured meat.
