Abstract: A process which may be continuous is provided for manufacture of personal care product compositions. The process involves feeding a first water phase which is a concentrate containing most if not all water soluble ingredients of the composition into a blending tube. A second phase which can be oily or aqueous and a third water phase, the latter being essentially pure water, are also fed into the blending tube. All of the phases are transported through the tube at a flow rate of about 5 to about 5,000 lbs./minute and at a pressure of about 10 to about 5,000 psi. Preferably the tube leads into a homogenizer such as a sonolator.

Abstract: A process is provided for manufacture of a personal care composition. Steps include separately feeding a first phase and optionally a second phase into a blending tube, each of the phases moving through the tube at a rate of at least about 5 pounds per minute. Mixing occurs in a homogenizer, in particular a sonic agitator. Thereafter, a late variant addition phase which may include a fragrance, colorant and/or promotional ingredient is fed into the homogenized first phase. The combination is then conveyed to a static mixer for completion blending.

Abstract: Capsules for protecting a benefit ingredient and/or a colorant usefull in detergent or personal care compositions. The benefit agent and/or colorant within the capsule is surrounded by a continuous phase based on a mixture of thermoplastic-type co-polymer and hydrocarbon oil. The continuous phase is preferably transparent. Detergent and personal care compositions containing the capsules are also described.

Abstract: The method disclosed is one wherein n pumps and n relative solenoid valves operated by a single microprocessor-controlled stepping motor dispense one or more of n colouring agents into a paint/varnish medium. The quantity dispensed is either a proper or improper fraction of an integer of 1/m of the volumetric unit of measure (fluid oz) and is defined p, a nominal value reflecting the number of half-steps indexed by the motor which is corrected proportionally by comparison of the effective and the nominal weight of a droplet downstream of the pump and upstream of the solenoid valve in order to produce an effective number of half-steps x. A similar correction is made to the number R of half steps which correspond to the delay occasioned by operation of the solenoid valve, comparing the effective and nominal weights of the droplet downstream of the valve; the speed of the motor is corrected to compensate for system resistances.
