The invention relates to new self-emulsifying preparations containing (a) 7 to 20% by weight stearyl oligoglycoside, (b) 7 to 20% by weight cetyl oligoglycoside, (c) 0.1 to 3% by weight myristyl oligoglycoside, (d) 0.5 to 7% by weight lauryl oligoglycoside, (e) 4 to 12% by weight cetyl alcohol, (f) 10 to 20% by weight stearyl alcohol, (g) 20 to 30% by weight C 16/18 partial glycerides containing 58 to 62% by weight monoglyceride and (h) 20 to 30% by weight C 16/18 partial glycerides containing 30 to 45% by weight monoglyceride, with the proviso that the quantities shown add up to 100% by weight with water.
1. A self-emulsifying base composition consisting of:
(a) 7 to 20% by weight stearyl oligoglycoside,
(b) 7 to 20% by weight cetyl oligoglycoside,
(c) 0.1 to 3% by weight myristyl oligoglycoside,
(d) 0.5 to 7% by weight lauryl oligoglycoside,
(e) 4 to 12% by weight cetyl alcohol,
(f) 10 to 20% by weight stearyl alcohol,
(g) 20 to 30% by weight C 16/18 partial glycerides containing 58 to 62% by weight monoglyceride,
(h) 20 to 30% by weight C 16/18 partial glycerides containing 30 to 45% by weight monoglyceride; and
(i) water to 100%.
2. The self-emulsifying base composition of claim 1 , wherein oligoglycosides (a) to (d) conform to formula (I):
R 1 O-[G] p (I)
wherein R 1 is an alkyl group containing 12, 14, 16 or 18 carbon atoms, G is a sugar unit containing 5 or 6 carbon atoms and p is a number of 1 to 10.
3. The self-emulsifying base composition of claim 1 , wherein the partial glycerides (g) and (h) conform to formula (III):
wherein R 3 CO is a linear saturated acyl group containing 16 or 18 carbon atoms, R 4 and R 5 independently of one another have the same meaning as R 3 CO or represent hydrogen, wherein, at least one of the substituents R 4 and R 5 independently represents hydrogen.
4. The self-emulsifying base composition of claim 2 , wherein the partial glycerides (g) and (h) conform to formula (III):
wherein R 3 CO is a linear saturated acyl group containing 16 or 18 carbon atoms, R 4 and R 5 independently of one another have the same meaning as R 3 CO or represent hydrogen, wherein, at least one of the substituents R 4 and R 5 independently represents hydrogen.
5. A member selected from the group consisting of cosmetic preparations and pharmaceutical preparations comprising the self-emulsifying base composition of claim 1 .
6. A member selected from the group consisting of cosmetic preparations and pharmaceutical preparations comprising from 0.1 to 8% by weight of the self-emulsifying base composition of claim 1 , based on the weight of the preparation.
7. A member selected from the group consisting of cosmetic preparations and pharmaceutical preparations comprising from 0.1% to 2% of the self-emulsifying base composition of claim 1 , based on the weight of the preparation.
