Electron Spin Echo Modulation Studies of Doxylstearic Acid Spin Probes in Frozen Vesicles: Interaction of the Spin Probe with D2O and Effects of Cholesterol Addition

Electron spin echo studies have been carried out for a series of x-doxylstearic acid ( x=5, 7, 10, 12, and 16 ) spin probes in frozen deuteriated aqueous solutions of phospholipid vesicles and cationic dioctadecyldimethylammonium chloride (DODAC) vesicles.Modulation effects due to interactions of the nitroxide group of the spin probes with D2O give information about the conformations of the probes and the degree of hydration of the surfactant headgroups as well as about the degree of packing of the alkyl chain.We show that DODAC headgroups are more hydrated than choline headgroups and that the doxylstearic acid probes show a larger tendenncy for bending in DODAC vesicles than in phospholipid vesicles.Upon addition of cholesterol into phospholipid vesicles, the headgroups are separated and their degree of hydration increases.
AMPHOLYTIC TER-POLYMERS FOR USE IN PERSONAL CARE COMPOSITIONS
-
, (2010/09/17)
Novel ampholytic ter-polymers comprising at least an ethylenically unsaturated cationic monomer, a monomer containing a carboxylic acid or sulfonic acid group and diallyamine or derivative are claimed. Further, the ter-polymers may be used in personal care or personal washing compositions optionally in the presence of conditioning agents such as silicone, fatty amines, fatty amine oxides and fatty quaternaries and/or various benefit agents. The ter-polymer compositions are especially useful in the treatment of keratin-containing substrates. Keratin substrates include, but are not limited to, animal and human hair, skin and nails.

The present invention provides a compound having the formula: STR1 in which each Rd is the same or different and each is --NH--Z--N(Ra)(Rb) or --N--?Z--N(Ra)(Rb)!2 in which Z is C2 -C14 alkylene or optionally substituted arylene, Ra and Rb are the same or different and each is C1 -C12 alkyl, or Ra and Rb, together with the nitrogen atom to which they are each attached, form a morpholino, piperidino or piperazino ring; each Rc is the same or different and is NH2, NH(C1 -C4 alkyl), N(C1 -C4 alkyl)2, N(CH2 CH2 OH)2, O--C1 -C4 alkyl, STR2 alkali metal atom, ammonium or a cation formed from an amine; or a quaternized form thereof. The present invention also relates to a composition for the treatment of textiles, in particular to a composition containing the new ultra-violet absorbing agents; and to a method for the improvement of both the sun protection factor (UPF) and the whiteness of textile fiber material, comprising treating the material with the composition according to the present invention.
