## Background
FIELD OF THE INVENTION
The present invention generally relates to agents for coloring and/or lightening keratinic fibers, in particular human hair. A further field of the present invention is that of ready-to-use agents that are produced by mixing one of the aforesaid agents with a further separate component including water and hydrogen peroxide.
BACKGROUND OF THE INVENTION
One skilled in the art knows of a variety of coloring systems, depending on the required color result, for making available color-changing cosmetic agents, in particular for keratinic fibers such as e.g. human hair. For permanent, intense color results having corresponding fastness properties, so-called “oxidation” coloring agents are used. Such coloring agents usually include oxidation dye precursors called “developer components” and “coupler components” that, under the influence of oxidizing agents such as hydrogen peroxide, form the actual dyes with one another. Oxidizing coloring agents are notable for outstanding, long-lasting color results. In addition to coloring, lightening of one's own hair color, and often hair-bleaching, is a very special desire of many consumers. For this, the natural or artificial dyes coloring the fibers are usually decolorized oxidatively using corresponding oxidizing agents, for example hydrogen peroxide.
In order to provide satisfactory coloring and lightening performance, oxidative coloring agents and/or lightening agents generally require an alkaline pH during utilization; optimum results are achieved in particular at pH values between 8.5 and 10.5.
Until the present time, ammonia has been the alkalizing agent of choice for establishing these pH values. Not only can ammonia be used to establish the pH range necessary for dye formation, but ammonia also ensures swelling of the hair to a greater extent than all other known alkalizing agents. At the same time, ammonia acts as a penetration adjuvant.
The applications-engineering advantages associated with the use of ammonia are so numerous that despite its unpleasant, pungent odor, ammonia is used in a large number of commercial oxidative coloring agents.
Extensive efforts to reduce the ammonia odor are already known from the literature. A variety of possibilities exist for minimizing the odor: as a first possibility, the literature recites varying the alkalizing agent and thus partly or entirely replacing ammonia with odorless alternatives.
A plurality of formulations that employ a mixture of ammonia and monoethanolamine, or exclusively monoethanolamine, as an alkalizing agent already exist in the literature. Reducing the ammonia content often results, however, in poorer penetration of the dyes into the hair, which can be reflected especially in poorer gray coverage and poorer washing fastness.
Although complete or partial replacement of ammonia with alternative alkalizing agents has advantageous effects in terms of minimizing the odor of the coloring and/or lightening agents, it is associated with disadvantages in terms of the fastness properties of the color results obtained with the coloring and/or lightening agents. If a corresponding replacement of the alkalizing agent is made, the resulting losses in terms of coloring performance must be compensated for by optimizing the formulation.
WO 2006060570 and WO 2006060565 propose the use of carbonates or carbonate sources as alkalizing agents in order to furnish oxidative coloring agents with little odor impact. It is likewise known in the literature, however, that carbonates in combination with oxidizing agents can damage the hair to a greater extent. The additional damage to the hair brought about by carbonates may not be much of a problem when utilizing the coloring agent on untreated or undamaged hair, but in the case of persons who regularly color or bleach their hair it can add up to serious cumulative damage. If more intense lightening and/or regular coloring is desired, the use of carbonates therefore once again does not represent a feasible alternative.
A second possibility, in principle, for reducing ammonia odor consists in the addition of special perfume substances that are intended to mask the ammonia odor. This approach is taken, for example, in WO 2005/110499. Perfume substances can be unstable under alkaline storage conditions, however, so that the risk exists that the scents may become degraded or structurally modified during storage, which is also reflected in an unpredictable change in odor. Because corresponding changes often become perceptible only after several months or even years, the employment of new or unknown perfumes is considered problematic.
A third general possibility for reducing ammonia odor consists in optimizing the formulation. The idea here is to select the carrier constituents of the formulation in such a way that they ensure optimum retention of ammonia in the formulation, and in that manner minimize its odor. It is once again known, however, that the formulation, the fatty substances included in it, its emulsifier agents and surfactants, and its viscosity have a substantial influence on coloring performance. When the formulation is modified, a deterioration in coloring performance must therefore in all cases be avoided.
For example, JP 2007191459 proposes the use of cationic surfactants, phosphate esters, and aliphatic alcohols in order to reduce ammonia odor in hair coloring agents.
JP 2003040750 discloses that the ammonia odor in hair-bleaching agents is particularly low when at least 5% of a crystalline component is added to the agents.
Although the literature proposes several methods for reducing the odor impact caused by ammonia, there is nevertheless no known possibility for completely suppressing ammonia odor.
It is therefore desirable to make available almost odorless agents for oxidative coloring and/or lightening of hair. To meet the performance requirements imposed on these agents, they are to include ammonia, but the ammonia odor is to be substantially completely masked. In particular, the complete masking of the ammonia odor is intended to persist over a long period of time, so that even after storage of the agents (in a closed vessel) for several weeks, optimally for several months, no ammonia odor is perceptible. At the same time, the agents are to exhibit no loss in terms of their coloring performance, in particular in terms of their gray coverage and their washing fastness. In addition, utilization of the agent is not to be associated with greater hair damage.
It is also desirable to successfully mask the ammonia odor for the entire duration of use, the intention being that even after a maximum of two hours of contact, no ammonia odor—and moreover also no other chemical odor—is to be perceptible.
Furthermore, other desirable features and characteristics of the present invention will become apparent from the subsequent detailed description of the invention and the appended claims, taken in conjunction with the accompanying drawings and this background of the invention.
BRIEF SUMMARY OF THE INVENTION
An agent for coloring and/or lightening keratinic fibers, in particular human hair, includes: ammonia in a quantity of 0.40 to 3.0 wt.-%, preferably of 0.50 to 2.4 wt.-%, more preferably of 0.60 to 2.0 wt.-% and especially preferred of 0.62 to 1.75 wt.-%, based on the weight of the agent; one or more alkanolamines from the group of monoethanolamine, 2-amino-2-methylpropanol, and triethanolamine; one or more ethoxylated fatty alcohols having a degree of ethoxylation from 80 to 120; cetyl alcohol and stearyl alcohol in a total quantity of 4 to 8 wt-%, based on the weight of the agent; and one or more ethoxylated fatty alcohols having a degree of ethoxylation of 30.


DETAILED DESCRIPTION OF THE INVENTION
The following detailed description of the invention is merely exemplary in nature and is not intended to limit the invention or the application and uses of the invention. Furthermore, there is no intention to be bound by any theory presented in the preceding background of the invention or the following detailed description of the invention.
In the course of the work leading to this invention it has emerged, surprisingly, that it is possible for the ammonia included in agents for coloring and/or lightening to be entirely masked in terms of olfaction, particularly for olfactory perception thereof to be completely prevented, when a special combination of different alkalizing agents is employed and when these various alkalizing agents are simultaneously combined with a mixture of specially ethoxylated fatty alcohols and cetearyl alcohol.
A first subject of the present invention is therefore an agent for coloring and/or lightening keratinic fibers, in particular human hair, including:

    
    
        (a) ammonia in a quantity of 0.40 to 3.0 wt.-%, preferably of 0.50 to 2.4 wt.-%, more preferably of 0.60 to 2.0 wt.-% and especially preferred of 0.62 to 1.75 wt.-%, based on the weight of the agent,
        (b) one or more alkanolamines from the group of monoethanolamine, 2-amino-2-methylpropanol, and triethanolamine,
        (c) one or more ethoxylated fatty alcohols having a degree of ethoxylation from 80 to 120,
        (d) cetyl alcohol and stearyl alcohol in a total quantity of 4 to 8 wt-%, based on the weight of the agent,
        (e) one or more ethoxylated fatty alcohols having a degree of ethoxylation of 30.
    
    


“Keratin-containing fibers” are understood in principle as all animal hair, e.g. wool, horsehair, angora wool, furs, feathers, and products or textiles produced therefrom. Preferably, however, the keratinic fibers are human hairs.
The term “agents for coloring and/or lightening” keratin fibers that is used according to the present invention is understood to mean agents for oxidative coloring of hair and agents for oxidative lightening or bleaching of hair.
In order to produce color, oxidative coloring agents include oxidation dye precursors, so-called “developers” and “coupler components.” Developers and couplers diffuse separately into the keratin fibers and, under the influence of ammonia as an alkalizing agent and an oxidizing agent (usually hydrogen peroxide), react chemically with one another to form the actual dyes. Depending on the quantity of oxidizing agent employed, the keratin fibers are simultaneously lightened to a greater or less extent during coloring, since the oxidizing agent not only initiates the dye-forming process of the developers and couplers, but also oxidatively destroys the hair's own pigments (melanins). Depending on the quantities of oxidation dye precursors and oxidizing agent that are used, the oxidative coloring process can therefore involve predominantly coloring (with a high dye proportion) or predominantly lightening (with a high proportion of oxidizing agent). In the latter case, the oxidation dye precursors are employed principally to tint the lightening result.
Agents for oxidative lightening or bleaching of hair often include hydrogen peroxide as the only oxidizing agent in order to achieve a moderate bleaching effect, but if there is a desire for more intense hair-bleaching performance they can also include oxidizing agent mixtures. In the latter case hydrogen peroxide is usually employed in combination with persulfates such as potassium persulfate, sodium persulfate, and/or ammonium persulfate. Agents for oxidative lightening or bleaching can likewise additionally include oxidation dye precursors, but the focus of these agents is on lightening of fibers.
In a preferred embodiment, the agents according to the present invention are agents for oxidative coloring of hair.
The agents according to the present invention include the constituents essential to the invention in a cosmetic carrier, preferably in a suitable aqueous, alcoholic, or aqueous alcoholic carrier. For hair-coloring purposes such carriers are, for example, creams, emulsions, gels, or also surfactant-including foaming solutions, for example shampoos, foam aerosols, foam formulations, or other preparations that are suitable for utilization on the hair.
As a first essential formulation constituent (a), the agents according to the present invention for coloring and/or lightening keratin fibers include ammonia in a quantity of 0.40 to 3.0 wt.-%, preferably of 0.50 to 2.4 wt.-%, more preferably of 0.60 to 2.0 wt.-% and especially preferred of 0.62 to 1.75 wt.-%, based on the weight of the agent.
Ammonia is employed preferably in the form of its aqueous solution. Corresponding aqueous ammonia solutions can be 10- to 35-percent solutions (calculated in wt %; 100 g aqueous ammonia solution accordingly includes 10 to 35 g ammonia). Ammonia is employed preferably in the form of a 20 to 30 wt % solution, particularly preferably in the form of a 25 wt % solution.
In order for the agents according to the present invention to conform to the requirements profile imposed upon them in terms of their color intensity and their fastness properties, it is not possible to dispense with the use of ammonia. It has emerged, however, that ammonia can be completely masked olfactorily if it is included in specific quantity ranges in the agents according to the present invention. Complete masking by means of the further ingredients (c), (d) and (e) that are essential to the invention and are likewise included in the agent according to the present invention is possible when the inventive agents include ammonia (a) in a quantity from 0.40 to 3.0 wt.-%, preferably of 0.50 to 2.4 wt.-%, more preferably of 0.60 to 2.0 wt.-% and especially preferred of 0.62 to 1.75 wt.-%, based on the weight of the agent.
In a more preferred embodiment, an agent for coloring and/or lightening keratinic fibers is therefore characterized in that it includes ammonia (a) in a quantity from 0.50 to 2.5 wt %, more preferably from 0.60 to 2.0 wt %, and particularly preferably from 0.62 to 1.75 wt %, based on the weight of the agent.
The aforementioned preferred and particularly preferred quantitative indications of ammonia (a) assume pure ammonia as a basis for calculation. If 0.62 to 1.75 wt % ammonia (a) is therefore employed very particularly preferably in the inventive agent, this corresponds to the utilization of a quantity from 2.48 g to 7.0 g of a 25 wt % ammonia solution in the inventive coloring agent.
When ammonia in the above-described quantity ranges is furthermore combined with the alkalizing agent (b), color results with high color intensity and outstanding fastness properties can then be generated with the corresponding agents according to the present invention. Surprisingly, with the use of a combination of the constituents (a) to (e) that are essential to the invention, not only are losses in color intensity avoided, but moreover the color results produced with these agents in fact exhibit improved gray coverage and improved washing fastness.
The agents according to the present invention for coloring and/or lightening keratinic fibers include, as a second constituent (b) essential to the invention, one or more alkanolamines from the group of monoethanolamine (2-aminoethanol, formula A), 2-amino-2-methylpropanol (2-amino-2-methylpropan-1-ol, formula B), and triethanolamine (formula C).




In order to achieve maximum odor masking and in order to optimize fastness properties, the alkanolamine(s) is/are also preferably employed in special quantitative ranges. Complete masking of the ammonia odor, and at the same time particularly good washing fastness values, are achieved when the alkanolamines (b) are included in a total quantity from 0.4 to 13 wt %, preferably from 1.0 to 8.0 wt %, more preferably from 1.54 to 5.0 wt %, and particularly preferably from 1.6 to 3.2 wt %, based on the weight of the agent.
In a further preferred embodiment, an agent for coloring and/or lightening keratinic fibers is therefore characterized in that it includes one or more alkanolamines (b) from the group of monoethanolamine, 2-amino-2-methylpropanol, and triethanolamine in a total quantity from 0.4 to 13 wt %, preferably from 1.0 to 8.0 wt %, more preferably from 1.54 to 5.0 wt %, and particularly preferably from 1.6 to 3.2 wt %, based on the weight of the agent.
A preferred agent according to the present invention includes, all quantity indications being based on the weight of the agent,

    
    
        (a) 0.40 to 3.0 wt % ammonia,
        (b) 0.4 to 13.0 wt % monoethanolamine,
        (c) in a total quantity of 0.2 to 3.0 wt.-%, preferably of 0.4 bis 2.4 wt.-%, further preferred of 0.6 to 1.8 wt.-% and especially preferred of 0.8 to 1.6 wt.-%, one or more ethoxylated fatty alcohols having a degree of ethoxylation from 80 to 120,
        (d) cetyl alcohol and stearyl alcohol in a total quantity of 4 to 8 wt.-%, and
        (e) in a total quantity of 4 to 8 wt.-% one or more ethoxylated fatty alcohols having a degree of ethoxylation of 30.
    
    


As a third formulation constituent (c) essential to the invention, the agents according to the present invention include one or more ethoxylated fatty alcohols having a degree of ethoxylation from 80 to 120.
“Fatty alcohols” are to be understood according to the present invention as saturated or unsaturated, unbranched or branched C8 to C28 alkyl groups with hydroxy substitution. Unsaturated fatty alcohols can be mono- or polyunsaturated. In the case of an unsaturated fatty alcohol, its carbon-carbon double bond(s) can exhibit the cis- or trans-configuration.
Preferred fatty alcohols are octan-1-ol (octyl alcohol, capryl alcohol), decan-1-ol (decyl alcohol, caprinyl alcohol), dodecan-1-ol (dodecyl alcohol, lauryl alcohol), tetradecan-1-ol (tetradecyl alcohol, myristyl alcohol), hexadecan-1-ol (hexadecyl alcohol, cetyl alcohol, palmityl alcohol), octadecan-1-ol (octadecyl alcohol, stearyl alcohol), (9Z)-octadec-9-en-1-ol (oleyl alcohol), (9E)-octadec-9-en-1-ol (elaidyl alcohol), (9Z,12Z)-octadeca-9,12-dien-1-ol (linoleyl alcohol), (9Z,12Z,15Z)-octadeca-9,12,15-trien-1-ol (linolenyl alcohol), eicosan-1-ol (eicosyl alcohol, arachyl alcohol), (9Z)-eicos-9-en-1-ol (gadoleyl alcohol), (5Z,8Z,11Z,14Z)-eicosa-5,8,11,14-tetraen-1-ol (arachidonyl alcohol), docosan-1-ol (docosyl alcohol, behenyl alcohol), (13E)-docosen-1-ol (brassidyl alcohol), and (13Z)-docos-13-en-1-ol (erucyl alcohol). Within this group in turn, hexadecan-1-ol (hexadecyl alcohol, cetyl alcohol, palmityl alcohol) and octadecan-1-ol (octadecyl alcohol, stearyl alcohol) are very particularly preferred fatty alcohols.
In order to constitute the constituent (c) essential to the present invention, these fatty alcohols are ethoxylated with a degree of ethoxylation from 80 to 120.
“Ethoxylation” (also “oxyethylation”) is understood as the reaction of fatty alcohols with ethylene oxide (EU). The insertion of from 80 to 120 groups of the —CH2—CH2—O— type per fatty alcohol molecule yields linear polyethers that carry at one end of the chain a hydroxy group and at the other end of the chain the C8 to C28 alkyl group of the fatty alcohol.
Preferred ethoxylated fatty alcohols (c) have a degree of ethoxylation from 90 to 110. It is very particularly preferred if ethoxylated fatty alcohols (c) having a degree of ethoxylation of 100 are employed.
In a further very particularly preferred embodiment, an agent for coloring and/or lightening keratinic fibers is characterized in that it includes as (an) ethoxylated fatty alcohol(s) (c) having a degree of ethoxylation from 80 to 120 one or more compounds of formula (I)




in which R1 denotes a saturated or unsaturated, unbranched or branched C8 to C24 alkyl group, preferably a saturated, unbranched C16 or C18 alkyl group, and

n denotes an integer from 80 to 120, preferably an integer from 90 to 110, and particularly preferably the number 100.

In the course of the work leading to this invention it has emerged that, surprisingly, the degree of ethoxylation of the ethoxylated fatty alcohol (c) substantially influences the ability of the agent to reduce ammonia odor. For this reason, it is particularly preferred if one or more ethoxylated fatty alcohols having a very specific degree of ethoxylation are employed as (an) ethoxylated fatty alcohol(s).
A particularly advantageous and thus explicitly very particularly preferred agent for coloring and/or lightening keratinic fibers is characterized in that it includes as (an) ethoxylated fatty alcohol (c) one or more compounds from the group of

In a further preferred embodiment, an agent for coloring and/or lightening keratinic fibers is therefore characterized in that it includes one or more ethoxylated fatty alcohols (c) having a degree of ethoxylation from 80 to 120 in a total quantity from 0.2 to 3.0 wt %, preferably from 0.4 to 2.4 wt %, more preferably from 0.6 to 1.8 wt %, and particularly preferably from 0.8 to 1.6 wt %, based on the weight of the agent.

Formation of the dyes in oxidative coloring agents occurs only under the influence of an oxidizing agent; hydrogen peroxide is usually used for this. In a preferred embodiment, hydrogen peroxide is used as an aqueous solution. According to the present invention, it is preferred that the agent according to the present invention (IA) and the accompanying oxidizing agent preparation (OA) are optimized for a weight-based mixing ratio (IA)/(OA) in the range of 0.33 to 3, preferably 0.5 to 2 and especially preferred 1 to 1.

It has proven to be advantageous if the oxidizing agent preparations according to the present invention additionally include at least one stabilizer or complexing agent in order to stabilize the hydrogen peroxide. Particularly preferred stabilizers are, in particular, EDTA and EDDS, and phosphonates, in particular 1-hydroxyethane-1,1-diphosphonate (HEDP) and/or ethylenediaminetetramethylenephosphonate (EDTMP) and/or diethylenetriaminepentamethylenephosphonate (DTPMP) or sodium salts thereof.
Furthermore, the agents according to the present invention can additionally include polymers and/or thickeners. Cationic, anionic, and/or zwitterionic polymers can be used as polymers. Examples of suitable anionic polymers are obtainable commercially, for example, under the trade names Carbopol® or Rheothik® 11-80. The polymers marketed under the INCI name Acrylates Copolymers are also suitable anionic polymers. A preferred commercial product is, for example, Aculyn® 33 of the Rohm & Haas company. Further preferred anionic polymers are marketed by the Rohm & Haas company under the trade name Aculyn® 22 and by the National Starch company under the trade names Structure® 2001 and Structure® 3001.

Coloring and lightening processes on keratin fibers usually proceed in an alkaline environment. In order to minimize stress on the keratin fibers and also on the skin, however, it is not desirable to establish too high a pH. It is therefore preferred if the pH of the agent according to the present invention is between 6 and 12, in particularly between 7 and 10.5. The pH values for purposes of the present invention are pH values that were measured at a temperature of 22° C.
The agents according to the present invention are agents for oxidative coloring and/or lightening of hair. In the ready-to-use agent, the oxidation dye precursors react with the oxidizing agent, accompanied by formation of the actual dyes. The agents according to the present invention are therefore commercialized as multi-component kits, in most cases as two-component kits. The first component includes the oxidation dye precursors and the alkalizing agent (preparation A), which is mixed shortly before utilization with a second component including the oxidizing agent (preparation B). The two components are usually mixed with one another at a weight ratio from 1:3 to 3:1, preferably 1:2 to 2:1, especially preferred 1:1. This mixture of the component including color cream/alkalizing agent (preparation A) and the component including oxidizing agent (preparation B) is referred to as the “utilization mixture” or the “ready-to-use agent.” All quantity indications with reference to the “ready-to-use agent” refer to the ready-to-use mixture of the agent according to the present invention, including dyestuff/alkalizing agent, and the component including oxidizing agent. All quantity indications with reference to the “agent” refer to the agent according to the present invention, including dyestuff/alkalizing agent.
A further subject of the present invention is therefore a ready-to-use agent for coloring and/or lightening keratinic fibers, which is characterized in that it is produced immediately before utilization by mixing preparations (A) and (B) in a weight-based mixing ratio (A)/(B) in the range of 0.33 to 3, preferably 0.5-2, especially preferred 1:1, wherein

    
    
        preparation (A) is an agent of the first subject of the invention,
        preparation (B) is an agent that includes, based on the weight of preparation (B), 80 to 95 wt.-% water, 1.0 to 23.0 wt %, more preferably 2.5 to 21.0 wt %, particularly preferably 4.0 to 20.0 wt %, and very particularly preferably 5.0 to 18.0 wt % hydrogen peroxide (calculated as 100-percent H2O2), and optionally one or more fatty alcohols from the group lauryl alcohol, myristyl alcohol, cetyl alcohol, stearyl alcohol, arachyl alcohol (eicosan-1-ol), gadoleyl alcohol ((9Z)-eicos-9-en-1-ol), arachidonyl alcohol ((5Z,8Z,11Z,14Z)-eicosa-5,8,11,14-tetraen-1-ol), behenyl alcohol (docosan-1-ol), erucyl alcohol ((13Z)-docos-13-en-1-ol), and brassidyl alcohol ((13E)-docosen-1-ol), in a total quantity of 0.01 to 3 wt.-%, preferably 0.1 to 2 wt.-%, further optionally at least one surfactant in a total quantity of 0.01 to 3 wt.-%, preferably 0.1 to 2 wt.-%, especially preferred 0.2 to 0.5 wt.-%, and further optionally at least one oil in a total quantity of 0.01 to 3 wt.-%, preferably 0.1 to 2 wt.-%, especially preferred 0.2 to 0.5 wt.-%.
    
    


A further subject of the present invention is a method for coloring and/or lightening keratinic fibers which is characterized in that

    
    
        if desired, a pretreatment agent PRE is applied onto the fibers, then
        a coloring and/or lightening agent (A), corresponding to the agent according to any of claims 1 to 11, is applied to the fibers, a further agent (B) being added if desired to the agent (A) before utilization, wherein preferably (A) and (B) are present in a weight-based mixing ratio (A)/(B) in the range of 0.33 to 3, preferably 0.5-2, especially preferred 1:1, and wherein the agent (B) preferably includes, based on the weight of preparation (B), 80 to 95 wt.-% water, 1.0 to 23.0 wt %, more preferably 2.5 to 21.0 wt %, particularly preferably 4.0 to 20.0 wt %, and very particularly preferably 5.0 to 18.0 wt % hydrogen peroxide (calculated as 100-percent H2O2), and optionally one or more fatty alcohols from the group lauryl alcohol, myristyl alcohol, cetyl alcohol, stearyl alcohol, arachyl alcohol (eicosan-1-ol), gadoleyl alcohol ((9Z)-eicos-9-en-1-ol), arachidonyl alcohol ((5Z,8Z,11Z,14Z)-eicosa-5,8,11,14-tetraen-1-ol), behenyl alcohol (docosan-1-ol), erucyl alcohol ((13Z)-docos-13-en-1-ol), and brassidyl alcohol ((13E)-docosen-1-ol), in a total quantity of 0.01 to 3 wt.-%, preferably 0.1 to 2 wt.-%, further optionally at least one surfactant in a total quantity of 0.01 to 3 wt.-%, preferably 0.1 to 2 wt.-%, especially preferred 0.2 to 0.5 wt.-%, and further optionally at least one oil in a total quantity of 0.01 to 3 wt.-%, preferably 0.1 to 2 wt.-%, especially preferred 0.2 to 0.5 wt.-%,

The utilization mixture produced in this manner was applied with an Aplicette onto hair strands (yak belly hair) and left there for a time period from 30 minutes. The utilization mixture was then rinsed out with a shampoo and dried. A caramel blonde color was obtained.
2. Determining Ammonia Odor During Utilization
The utilization mixture previously produced (E1+OX1) was applied onto the head of a test subject. During the utilization time period, the ammonia odor was evaluated in each case by five trained persons at various points in time (directly after application at 0 min, after 10 min, after 20 min, and after 30 min) The evaluation was performed blind, meaning that the persons who performed the evaluation did not know which formulation they were evaluating at the time. The average was calculated from the individual evaluations.
The ammonia odor was evaluated on a scale from 0 (virtually no odor perceptible) to 10 (very strong ammonia odor).
