O/W-emulsifiers, O/W-emulsions and methods of manufacture thereof
View Patent ↗O/W-emulsifiers are described, comprising: (a) 30-50% by weight of hardened palm oil glycerides; (b) 15-35% by weight of potassium cetyl phosphates; (c) 20-30% by weight of cetyl alcohol, and (d) 5-15% by weight of potassium phosphate, in each case with respect to the total mass of the emulsifier. Further described are corresponding O/W-emulsions, comprising an aqueous phase, an oil phase dispersed in the aqueous phase and between 0.25 and 15% by weight of the abovementioned O/W-emulsifier. Finally, also described are methods for manufacturing such an O/W-emulsion.
1. An O/W-emulsifier, comprising:
(a) 30-50% by weight of hardened palm oil glycerides;
(b) 15-35% by weight of potassium cetyl phosphates;
(c) 20-30% by weight of cetyl alcohol; and
(d) 5-15% by weight of potassium phosphates;
wherein the percentages by weight indicated relate to the total mass of the 01W-emulsifier,
and wherein the potassium phosphates of component (d) do not comprise potassium cetyl phosphates.
2. The O/W-emulsifier as claimed in claim 1 , wherein the emulsifier contains no polyethylene glycol (PEG) and/or no other glycol and/or no paraffin and/or no isoparaffin.
3. The O/W-emulsifier as claimed in claim 1 , consisting of:
(a) 35-45% by weight of hardened palm oil glycerides;
(b) 15-35% by weight of potassium cetyl phosphates;
(c) 25-30% by weight of cetyl alcohol;
(d) 5-10% by weight of potassium phosphates; and
(e) 0-15% by weight of other substances;
wherein the percentages by weight indicated relate to the total mass of the O/W-emulsifier.
4. The O/W-emulsifier as claimed in claim 1 , wherein the component (b) comprises potassium monocetyl phosphate and potassium dicetyl phosphate in a ratio by weight of between 10:1 and 2.5:1.
5. The O/W-emulsifier as claimed in claim 1 , wherein the component (d) comprises potassium hydrogen phosphate.
6. The O/W-emulsifier as claimed in claim 1 , wherein the O/W-emulsifier is in the form of pastilles.
7. The O/W-emulsifier as claimed in claim 4 , wherein the component (b) comprises potassium monocetyl phosphate and potassium dicetyl phosphate-in a ratio by weight of between 6:1 and 3:1.
8. The O/W-emulsifier as claimed in claim 5 , wherein the potassium hydrogen phosphate is 4% by weight or higher, with respect to the total mass of the O/W-emulsifier.
