FIELD OF INVENTION
The present invention relates to a hair color composition and more particularly to
a hair color composition comprising a powder hair color and a novel conditioning
milk formulation.
BACKGROUND OF INVENTION
The desire to alter the color of human hair is not a facet of modem times. Since
the days of the Roman Empire the color of human hair has been routinely altered
to accommodate the changes of fashion and style. However, the attainment of
precise initial colors which are retained by the hair for a desirable period has
remained a more elusive goal. The difficulties in the development of hair coloring
compositions which can deliver precise long-lasting colors are in part due to the
inherent structure of the hair itself and in part due to the necessary conditions of
effective hair coloration processes. In the modern era hair color is not employed
just to cover grey hair, but also to add highlights, supplement the natural hair
color, provide new attractive colors etc.
Hair color compositions are broadly classified as permanent, demi-permanent,
semi-permanent and temporary. The permanent hair colors involve synthetic
chemicals like dyes and oxidants that provide a persistent coloration for a long
period of time. Subsequent dyeing is usually necessitated by hair growth. Demipermanent
hair color is permanent hair color that contains an alkaline agent other
than ammonia (e.g. ethanolamine, sodium carbonate) and, while always employed
with a developer, the concentration of hydrogen peroxide in that developer may be
lower than used with a permanent hair color. Since the alkaline agents employed
in demi-permanent colors are less effective in removing the natural pigment of
hair than ammonia these products provide no lightening of hair's color during
dyeing. As the result, they cannot color hair to a lighter shade than it was before
dyeing and are less damaging to hair than their permanent counterpart. Semipermanent
hair color has smaller molecules than temporary dyes. These dyes only
partially penetrate the hair shaft. For this reason, the color will survive repeated
washing, typically 4-5 wash or a few weeks. Semi-permanents contain no, or very
low levels of developer, peroxide or ammonia, and are therefore safer for
damaged or fragile hair. However, semi-permanents may still contain the toxic
compound .The temporary colors fade or get washed away in just a few washes,
usually less than two. However, various colorant mentioned above usually contain
harmful chemicals that cause dermatological problems and skin allergies. Thus,
there has been a shift towards natural ingredients for providing hair color.
Natural dyeing is a valuable part of herbal medicine and its biggest advantage is
not to hurt the skin, care and maintenance effect on the human body during its
use. The powder hair color of the present invention is obtained from natural
sources like Henna and Amla.
Henna (Lawsonia inermis, also known as Mehendi, the henna tree, the mignonette
tree, and the Egyptian privet) is aflowering plantand the sole species of
the Lawsonia genus. This is not known to have any significant side effects. The
use of Henna powder to color and condition the hair has been known for at least
2,000 years. Another form of Henna is known as "Black Henna" which may be
derived from indigo (from the plant Indigofera tinctoria). It may also contain
unlisted dyes and chemicals. "Black henna" may containp-
Phenylenediarnine (PPD) and is used to blend with Lawsonia Hennas to produce
darker shades. This is not useful when a natural shade of hair is required and in
the twentieth century the use of Henna declined in favor of other synthetic
formulations. However, with the current emphasis on natural products, Hennabased
hair dyeing and conditioning compositions are enjoying heightened
popularity.
Modem commercial preparations are generally powders which are mixed with
water, applied to the hair as slurry, covered with a cap for about 1 hour and then
rinsed off from the hair with water. While the currently available Henna
preparations impart various shades of red to the hair and, in addition add body and
luster to the treated hair, they have a number of disadvantages. They have a strong
tendency to coalesce into small balls, forming a lumpy mixture which is difficult
to apply uniformly to the hair. Complete grey coverage is also not possible due to
improper wetting of Henna and low viscosity lumpy mixture whose application
can't be controlled/ easily drips out from hair. Further, the Henna slurry is
difficult to rinse from the hair.
Moreover, the commercial products in the market are difficult to wet and take
longer time for mixing and result into a thin mass.
Thus, there is a need to provide a hair color composition comprising natural
ingredients like Henna. There is a need for a hair color composition that provides
natural hair colors that do not fade away after several washes. It is also desired to
provide a hair color composition whose ingredients can be easily mixed into a
creamy mass that easily spreads and does not drip upon application to hair.
There is also a need for a haii color composition that provides complete grey
coverage. There is also a need for a hair color composition without ammonia that
gets easily rinsed off and does not irritate eyes and gives natural color to hair.

Process of preparation of powder hair color
The process of preparation of powder hair color is prepared in three stages namely
pre-mixing stage, mixing stage and post-mixing stage.
1. Pre-mixing stage
Both henna powder and the amla powder are sieved through a suitable sieve and
then dried at 88-~o'c, to reduce moisture content by 1.5-2.0% and 2.5-3.0%
respectively. The required quantity of the sieved henna and sieved amla is then
dispensed as per the requirement of the formulation.
The mixture of p-phenylenediamine, p-aminophenol, p-phenylenediamine
sulphate, p-aminophenol sulphate, resorcinol and/or the analogue mixture thereof
is ground separately and further sieved through 40 mesh stainless steel sieve. The
rest of the raw material including tartaric acid, polyquaternium-37, sodium lauryl
sulphate, sodium sulphite and black olive extract are dispensed in required
quantities as per the formulation ensuring that all the raw materials are at room
temperature.
2. Mixing stage
In the mixing stage, in a suitable blender amla powder is taken to which a mixture
of the above mentioned raw materials is added and mixed. To this blender the
sieved henna powder is added and mixed for few minutes by maintaining the
rotation of the blender to 30-35rpm. The grounded mixture of pphenylenediamine,
p-arninophenol, p-phenylenediamine sulphate, p-aminophenol
sulphate, resorcinol andlor the analogue mixture thereof is added to the blender
and resulting bulk is mixed thoroughly. Sodium perborate is added to the blender
and the bulk is mixed for one hour.
3. Post-mixing stage
The bulk obtained in the mixing stage is passed through the 40 mesh sieve and the
sample is collected for lab analysis. After confirmation of quality, bulk is released
and packed in air tight bags and stored in a dry area. The powder hair color hence
obtained is packaged under nitrogen purging on the same day.
Example 3
Process of preparation of conditioning milk formulation
DM water, propylene glycol, milk powder, disodium EDTA and acrylates/ClO-30
alkyl acrylate crosspolymer are placed into vessel-1 and heated up to 75-80'~. In
the vessel-2, with a side pot arrangement stearic acid, glyceryl monostearate, cetyl
alcohol, light liquid paraffin, almond protein, cetyl acetate and acetylated lanolin
alcohol and dimethicone were placed in vessel-2 and steam heated with a slow
stirring. The mass in the vessel-2 is then melted by maintaining the temperature in
the range of 78-80'~ while ensuring that the mass does not get overheated due to
localized heating of the inner surface of the side pot.
Once temperature of both the vessels reaches 75-8o0c, 400mrn Hg vacuum is
applied to both vessels and the homogenizer is started at the medium speed. The
oil phase of vessel-2 is simultaneously filtered through 100 mesh and slowly
added through the suction to the solution of the vessel-I. The side pot of the
vessel-1 is flushed with hot water to ensure any leftover oil phase transferred to
the vessel-I. After 5 minutes of homogenization, triethanolamine is added to
adjust the pH. This mixture is homogenized at medium speed for 15 minutes
while maintaining the temperature at 75'~. The homogenization is stopped after
15min and mixing was continued by agitator and scrapper at low speed. At the
same time the de-aeration using vacuum 650rnrn is continued and the mixture is
cooled.
The mixture of a suitable fragrance and tocopherol acetate is added to vessel-1
below 40'~. The preservative solution is then added and mixed for 20min. The pH
of the bulk solution was then adjusted in between 6-7 by adding triethanolamine.
The conditioning milk formulation of present invention is then submitted for
quality assurance analysis as per in-house specification and then packaged using
suitable packaging material.
