Physiological levels of diacylglycerols in phospholipid membranes induce membrane fusion and stabilize inverted phases.

Abstract: In the preceding paper (Ellens et al., 1989), it was shown that liposome fusion rates are substantially enhanced under the same conditions which induce isotropic 31P NMR resonances in multilamellar dispersions of the same lipid. Both of these phenomena occur within the same temperature interval, delta TI, below the L alpha/HII phase transition temperature, TH. TH and delta TI can be extremely sensitive to the lipid composition. The present work shows that 2 mol% of diacylglycerols like those produced by the phosphatidylinositol cycle in vivo can lower TH, delta TI, and the temperature for fast membrane fusion by 15-20 degrees C. N-Monomethylated dioleoylphosphatidylethanolamine is used as a model system. These results show that physiological levels of diacylglycerols can substantially increase the susceptibility of phospholipid membranes to fusion. This suggests that, in addition to their role in protein kinase C activation, diacylglycerols could play a more direct role in the fusion event during stimulus-exocytosis coupling in vivo.

Cleansing articles for skin and/or hair which also deposits skin care actives

Abstract: The present invention relates to a substantially dry, disposable, personal cleansing article useful for both cleansing the skin or hair and delivering skin care actives onto the skin or hair. These articles are used by the consumer by (i) wetting the dry article with water and (ii) generating lather by subjecting the wetted article to mechanical forces, e.g., rubbing. The article comprises a water insoluble substrate, a lathering surfactant, and a skin care active component. Preferably, the articles of the present invention further comprise a deposition aid and/or a conditioning component.

Fabric conditioning composition

Abstract: Fabric conditioning compositions contain particles of size 0.1 to 200 microns and of melting point 38° C. to 150° C. and comprising a wax-like carrier substance and a perfume. The particles are distributed throughout a composition, especially an aqueous fabric-softening composition, which contains a fabric-substantive cationic surfactant.

Pyridinethione salts and hair care compositions

Abstract: Metal salts of pyridinethione useful in shampoos, creme rinses and other hair care compositions to deliver antidandruff benefits while not detracting as much as previous pyridinethione salts from the compositions' aesthetics Compositions containing such salts are also included
