Abstract
Discrete particle aggregates and/or discrete particle agglomerates for application onto keratin fibers, preferably hair, optionally combined with one or more oxidative and/or direct dyes.
Claims8
A method of manufacturing discrete particle aggregate, agglomerate and combinations threreof comprising the steps of
- i) providing a primary particle having a particle size greater than 1000 nm
- ii) preferably milling said particles to a particle size of from about 20 nanometers to about 400 nanometers and
- iii) sonicating said particles.
A method of manufacturing discrete particle aggregate, agglomerate and combinations thereof comprising the steps of:
- i) dispersing a chromophoric material into an aqueous or non aqueous solution;
- wherein the starting mean particle size is larger than 1000 nanometers resulting is a chromophoric material dispersion
- ii) milling the chromophoric material dispersion to result in a milled chromophoric material dispersion with the chromophoric material having a mean particle size less than the starting mean particle size;
- and
- iii) sonicating the milled chromophoric material dispersion to obtain resulting a mean particle size of the chromophoric material from about 20 nanometers to about 400 nanometers.
A method of manufacturing discrete particle aggregate, agglomerate and combinations thereof comprising the steps of:
- i) dispersing a chromophoric material into an aqueous or non aqueous solution;
- wherein the mean particle size is from about 20 nanometers to about 400 nanometers resulting is a chromophoric material dispersion
- ii) sonicating the chromophoric material dispersion.
A method of coloring keratin fibers comprising the steps of:
- i) applying to keratin fibers to an aqueous or non aqueous solution containing a particle aggregate, agglomerate and combinations thereof;
- wherein said aggregate and agglomerate consist of a chromophoric material;
- and further wherein said aggregate and agglomerate possesses a size of from about 20 nanometers to about 400 nanometers;
- ii) allowing the discrete particle aggregate, agglomerate and combinations thereof to penetrate the keratin fibers with the particle aggregate, agglomerate and combinations thereof;
- and
- iii) rinsing the keratin fibers.
