Abstract: A positive displacement mixer and method for mixing a product that mixes at least two materials into a homogenous product. The positive displacement mixer has at least one positive displacement element having a length, a primary compartment, and a moving element, and two or more minor positive displacement elements each having a length, a minor compartment, and a moving element. The primary compartment and the minor compartments are fluidly connected and during mixing the primary compartment and minor compartments are closed to the atmosphere.

Abstract: A process of making fragrance compositions by adding solvents with different polarity before and after a filtering step to accelerate precipitation of e.g. waxy carry-overs from perfume oils.

Abstract: A continuous in-line process of making fragrance compositions increases the rate of production, compared to traditional batch processes, by having a chilling step that accelerates precipitation transformation.

Abstract: A continuous in-line process of making fragrance composition by the ratio addition of solvents pre- and post- the filtering step to accelerate wax precipitation formed from waxy carry-overs from the perfume raw materials.

Abstract: The personal care article comprises a single chamber package and a personal care product. The package comprises a dispensing orifice, a first zone, a second zone and a third zone that are located proximal, medial and distal to the dispensing orifice. The personal care product comprises a first, a second and a third personal care composition with a first, second, and third concentration of hydrophobic benefit material. The first, second, and third personal care compositions are substantially within the first, second and third zones. The personal care product comprises a second concentration that is greater than the first and third concentration of hydrophobic benefit material. The personal care product is sequentially dispensed, such that, the first personal care composition is capable of being substantially dispensed prior to the second and third personal care compositions and the second is capable of being substantially dispensed prior to the third personal care composition.
