This invention discloses a solubility aid for very high density powders of 650 g/L or greater density and having a low particle porosity of 25% or less. The solubility aid is a non-surfactant alkylene oxide condensate.

Cold water solubility for high density detergent powders

A folding pour spout, particularly, for detergent cartons. The spout is formed from a spout blank preferably comprising a single thin sheet of plastic. The spout blank includes a first spout-forming panel having a pull tab, a second spout-forming panel including notches and a panel for attachment to a carton. The reduced thickness of the spout blank facilitates manufacturing of the carton.

Folding pour spout

A plastic closure for cartons which permits controlled dispensing of product. The closure is a fitment comprised of a thin material which is of such a minimal thickness that it does not tend to cause uneven stacking of the cartons when they are in flattened form, prior to their erection. The closure is generally thin enough to be accommodated within a carbon having either a 3- or 4- point rule score and normal score caliper balancing. The closure comprises a base member having an aperture, and a cover member which has a depending plug which fits within the aperture of the base when the cover member is in the closed position.

Ultrathin carton closure

A fabric softening particle is provided comprising a mixture of quaternary ammonium ion-exchanged clay having an ion-exchange capacity of at least about 10 meq/100 gms and preferably about 50 meq/100 gms and a water-insoluble quaternary ammonium salt in the ratio of 1:3 to 3:1. The particle softens more efficiently than either of its components. When incorporated into a detergent powder, detergency is not diminished as would occur when either of the particle components are separately incorporated.
