Abstract: A system for dry cleaning soils from fabrics comprising densified carbon dioxide and a surfactant in the densified CO.sub.2. The densified carbon dioxide is in a temperature range of about -78.5.degree. C. to about 100.degree. C. and a pressure range of about 14.7 to about 10,000 psi. At least 0.1% by volume of a modifier is preferably present. The surfactant has a polysiloxane, a branched polyalkylene oxide or a halocarbon group which is a functional CO.sub.2 -philic moiety connected to a CO.sub.2 -phobic functional moiety. The surfactant either exhibits an HLB of less than 15 or has a ratio of siloxyl to substituted siloxyl groups of greater than 0.5:1.

Abstract: The present invention relates to skin cleansing bar composition in which polyalkylene glycols of very specific molecular weights are used to define compositions which are mild, foam well and provide consumer-desired sensory profiles. A significant amount of these specific PEGs must be incorporated into the bar to deliver these desired effects. To properly process such a bar composition, the cast-melt method is the preferred technique.

Abstract: An aqueous cleansing and oily soil removing composition comprising a surface active agent and an agent for removing oily soil from skin, in which the surface active agent and agent for removing oily soil are separate but combinedly dispensable from a single packaging means as discrete domains, preferably in a predetermined ratio. Separating the agent for removing oily soil from the surface active agent results in improved removal of oily soil from skin, and a clean, fresh feel which is appreciated by the consumer.

Abstract: A carton having one or more closure flaps with a delaminating window formed by lines which are not substantially straight in a direction parallel to the fold line separating the flap from the panel of the carton. Preferably, the delaminating window is formed from an undulating curve. The lack of straight lines tends to minimize the risk that bending will occur and interfere with the sealing of the carton. The invention also includes a process of sealing the cartons by adhering the delaminating window to another flap.
