Abstract: Liposomes are prepared comprising a polyhydroxybutyrate calcium polyphosphate complex which provides for uptake of a desired component, particularly nucleotides and nucleic acids. The charged species may be introduced into the lumen of a liposome by incubating liposomes with a solution of the component of interest for sufficient time to provide for introduction of the component into the lumen of the liposome, followed by washing at diminished temperatures. The resulting liposomes may then be used as vehicles for delivery of the lumen component.

Abstract: A method of providing a cosmetic product or a cleaning composition with defoaming properties, includes adding to the cosmetic product or the cleaning composition a triethanolamine product mixture which has not been distilled and which is composed of a major part by weight of triethanolamine; a minor part by weight of diethanolmono-C.sub.3-4 -alkanolamine and monoethanoldi-C.sub.3-4 -alkanolamine; and less than 1% by weight of a mixture of diethanolamine and monoethanolamine. Preferably, the triethanolamine product mixture is composed of from 60-90% by weight of triethanolamine; from 10-40% by weight of a mixture of diethanolmono-C.sub.3-4 -alkanolamine and monoethanoldi-C.sub.3-4 -alkanolamine; and less than 1% by weight of a mixture of diethanolamine and monoethanolamine.

Abstract: A cosmetic or body composition containing an effective amount of a non-leachable anti-microbial polymer. The polymer contains carboxyl groups which are at least partially neutralized or exchanged with anti-microbial quaternary ammonium cations or anti-microbial polyamides.
