Aspects of the present invention are directed to compositions and method of lifting the color of hair or for altering the color of hair comprising at least one alkalizing agent, at least two fatty substances, at least one surfactant, at least one cationic polymer, at least one thickening agent, at least one solvent, and optionally at least one colorant.
It is known that consumers desire to use cosmetic and personal care compositions that enhance the appearance of keratinous substrates such as hair and skin by changing the color of the hair or skin and/or by imparting various properties to hair or skin such as shine and conditioning. The process of changing the color of hair can involve either depositing an artificial color onto the hair which provides a different shade or color to the hair or lifting the color of the hair, such as for example, from a dark brown shade to a medium brown or a light brown shade.
In certain instances, hair lightening compositions may possess an alkalinity such that these compositions may have a pH value of above 7 and may require the presence of an alkaline agent. Furthermore, it is preferable to formulate such compositions that are less costly to manufacture by requiring fewer ingredients and/or lower levels of ingredients. In general, hair lightening or color lifting compositions may require the presence of an alkalizing agent such as ammonia or an ammonia gas generating compound and/or an amine or ammonium-based compound in amounts sufficient to make such compositions alkaline. These alkalizing agents also cause the hair shaft to swell, thus allowing the small oxidative dye molecules to penetrate the cuticle and cortex before the oxidation condensation process is completed. The resulting larger-sized colored complexes from the oxidative reaction are then trapped inside the hair fiber, thereby permanently altering the color of the hair. However, the use of ammonia may affect the user, not only because of the undesirable odor of ammonia, but because it may also pose greater risks of intolerance, for instance, irritation of the scalp and stinging.
The process of altering the color of hair by lifting or lightening or depositing the color of the hair, generally requires the use of compositions that comprises mineral oil as a common source of fatty compound in compositions that use MEA as the main source of alkalinity. However, mineral oil is derived from the petroleum industry and greener alternatives would be preferable.
It is also important to provide hair coloring compositions with various types of consistencies, such that the compositions can be provided in the form of a liquid emulsion, such as a liquid-lotion, liquid-gel, liquid-cream, or a cream emulsion, such as a thick cream or gel-cream, or a foam or mousse wherein the liquid emulsion form has a thinner consistency than the cream emulsion form and is typically packaged in a bottle. The liquid emulsion form is generally employed when the entire head of hair is to be colored or when only one color is desired since the dye composition spreads easily, allowing for greater coverage while the cream emulsion form can be employed for dyeing the entire head of hair and for highlighting or lightening only certain sections of the hair.
The option of replacing all or at least some of the aqueous ammonia with at least one other standard alkalizing agent frequently does not lead to compositions that are as efficient as those based on aqueous ammonia.
Thus, there is still a need for compositions which color the hair or otherwise alter the color of the hair which are more environmentally friendly, minimize damage to the hair and is inexpensive to produce.

For example, the hair color composition may be left on the hair for up to one hour, such as from about 3 minutes to about 45 minutes, from about 5 minutes to about 30 minutes, or from about 10 minutes to about 20 minutes. In further embodiments, the hair color composition may be left on the hair for a period up to about 30 minutes, such as, for example, from about 1 to about 30 minutes, about 1 to about 10 minutes, or about 1 to about 5 minutes. One skilled in the art will, by considering various factors such as the starting and desired tones of the hair, be able to determine an appropriate amount of time to leave the hair color composition on the hair in order to achieve the desired alternation in hair tone. By way of non-limiting example, various embodiments according to the disclosure may provide for an increase of 1 to 4 in the tone height of the hair.
If desired, the composition may, optionally, be shampooed and/or rinsed off the hair.
The amounts of each component in the compositions described below are expressed in % by weight, based on the total weight of the hair color base composition.
Performance Testing Method
Performance test was conducted using the panelists who usually use permanent hair coloring products to color their hair and are trained to evaluate the scalp discomfort. Variations of different shades of both inventive formulas and comparative formulas were applied on the hair in a controlled quantity and in a randomized way during a study conducted in a controlled environment. First, both products (inventive and comparative) contained in bowls were applied in a controlled quantity on the hair and scalp of each half of the head with a brush. The compositions were left on the hair for a period of about 30 minutes, and then rinsed off. During that time, the intensity of the feelings experienced by the panelists was evaluated and recorded by them at the different stages of the application of both products using a questionnaire, which consisted of structured linear scales to evaluate scalp comfort, such as burning, itching and stinging sensations. Different stages/time point of the evaluations included: before application of the products, upon the application of the products, during the processing time (at 2, 5, 10, 15, 20, and 30 minutes from the end of the application), and rinsing.
Above mentioned performance testing method was used to collect the data as shown in
Above mentioned performance testing method was used to collect the data as shown in
Compared to the comparative example B in the Table 2, the inventive example A had low levels of ammonium hydroxide, surfactants and cationic polymers in a combination with high levels of fatty compounds, glycol distearate and hydrogenated vegetable oil. Surprisingly, even with the low levels of ammonium hydroxide, surfactants and cationic polymers in a combination with high levels of fatty compounds, and in particular, with glycol distearate and hydrogenated vegetable oil, the performance of inventive example A was equal to or better than that of example B, as seen in
