Appeal No. 2004-0378
Application No. 09/765,675
20. A nanoemulsion according to claim 17, wherein said anionic amphiphilic
lipids are chosen from:
- alkyl ether citrates,
- alkoxylated alkenyl succinates,
- alkoxylated glucose alkenyl succinates, and
- alkoxylated methylglucose alkenyl succinates.
23. A nanoemulsion according to claim 1[,] further comprising at least one
ionic amphiphilic lipid chosen from cationic amphiphilic lipids and anionic
amphiphilic lipids chosen from:
- alkaline salts of dicetyl phosphate and of dimyristyl phosphate;
- alkaline salts of cholesteryl sulfate;
- alkaline salts of cholesteryl phosphate;
- lipoamino acids and salts thereof;
- sodium salts of phosphatidic acid;
- phospholipids; and
- alkyslulfonic derivatives of formula:
R-CH-CO-O-(CH2-CH2-CO)-CH3
l
SO3M
in which R, which may be identical or different in embodiments wherein
more than one of said alkylsulfonic derivative is used, is chosen from
C16-C22 alkyl groups, and M is chosen from alkali metals and alkaline-earth
metals.
64. A nanoemulsion according to claim 1 further comprising at least one
aminosilicone.
78. An oil-in-water nanoemulsion comprising oil globules with an average size
of less than 150nm comprising at least one oily phase, at least one
amphiphilic lipid, and at least one nonionic polymer comprising at least
one hydrophobic block and at least one hydrophilic block.
