Abstract
The present application provides preparations for changing the color of keratinic fibers, containing in a cosmetically acceptable carrier, at least one color-changing agent, at least one soap, and at leaset one non-ionic surfactant of formula (I), in which R1 denotes an alkyl or alkenyl residue having 5 to 21 carbon atoms, R2 denotes a C2-C4 monohydroxyalkyl residue, and R3 denotes hydrogen, a C1-C4 alkyl residue or a C2-C4 monohydroxyalkyl residue.
Claims15
A preparation for changing the color of keratinic fibers, containing, in a cosmetically acceptable carrier:
- at least one color-changing agent;
- at least one soap;
- and
- at least one non-ionic surfactant of formula (I),
- in which:
- R1 denotes an alkyl or alkenyl residue having 5 to 21 carbon atoms;
- R2 denotes a C2-C4 monohydroxyalkyl residue;
- and
- R3 denotes hydrogen, a C1-C4 alkyl residue or a C2-C4 monohydroxyalkyl residue.
A method for changing the color of keratinic fibers, the method comprising:
- applying to the fibers at the same time a preparation and an oxidizing agent preparation, in which:
- the preparation comprises:
- at least one color-changing agent;
- at least one soap;
- at least one propellant;
- and
- at least one non-ionic surfactant of formula (I),
- in which:
- R1 denotes an alkyl or alkenyl residue having 5 to 21 carbon atoms;
- R2 denotes a C2-C4 monohydroxyalkyl residue;
- and
- R3 denotes hydrogen, a C1-C4 alkyl residue or a C2-C4 monohydroxyalkyl residue;
- and
- the oxidizing agent preparation comprises, in a cosmetic carrier:
- at least one oxidizing agent;
- and
- a propellant;
- distributing the preparation and the oxidizing agent preparation uniformly over the fibers;
- and
- rinsing the preparation and the oxidizing agent preparation out of the fibers after a contact time of 10 to 45 min at a temperature of 20 to 45° C.
A packaging unit comprising:
- at least one first container which contains a preparation that comprises:
- at least one color-changing agent;
- at least one soap;
- at least one propellant;
- and
- at least one non-ionic surfactant of formula (I),
- in which:
- R1 denotes an alkyl or alkenyl residue having 5 to 21 carbon atoms;
- R2 denotes a C2-C4 monohydroxyalkyl residue;
- and
- R3 denotes hydrogen, a C1-C4 alkyl residue or a C2-C4 monohydroxyalkyl residue;
- and
- at least one second container which contains an oxidizing agent preparation that comprises, in a cosmetic carrier:
- at least one oxidizing agent;
- and
- a propellant.
