Embodiment 1
[0360] Example 1 - Formulation Example
[0361] The following compositions of the present disclosure were prepared:
[0362] Table 1 Liquid emulsion color alkali composition
[0363]
[0364] a From about 63 to about 70mm at 40°C 2 Viscosity / s; from supplier Sonoban USA under the trade name Heavy white mineral oil or from the supplier ExxonMobil Chemical under the trade name Primol TM 352 commercially available
[0365] Table 2 liquid emulsion color alkali composition
[0366]
[0367] a From about 63 to about 70mm at 40°C 2 Viscosity / s; from supplier Sonoban USA under the trade name Heavy white mineral oil or from the supplier ExxonMobil Chemical under the trade name Primol TM 352 commercially available
[0368] Each of the formulations in Tables 1 and 2 above was prepared as follows (total 1000 grams):
[0369] The acrylate copolymer (with Aqua SF-1 (commercially available) was added to water and the resulting solution was mixed with a VMI Rayneri mixer ...
Embodiment 2
[0386] Example 2 - Hair Coloring Study; Chromaticity Measurements
[0387] Agents for changing the color of hair are prepared by mixing a color base composition and an oxidizing composition and are intended to color hair in the following manner when used:
[0388] - mixing 10 g of color base composition A with 10 g of oxidizing composition B;
[0389] - apply the resulting mixture to a hair sample;
[0390] -The hair swatches are then shampooed, rinsed and then dried.
[0391] If desired, the color base composition can be mixed with the oxidizing composition in a ratio of 1:1, or in a ratio of 1:2, or in a ratio of 1:3.
[0392] Depending on the pH of the color base composition, the resulting mixture has a pH greater or less than 7.
[0393] Each formulation in the table below was mixed with an oxidizing composition, B (eg, the composition in Table 5) according to the procedure above to form a reagent for changing the color of hair (swatches). After dyeing the hair, the co...

[0447] Example 3 - Suspension / Stability Study
[0448] Samples of the color base composition of the invention were placed in a temperature-controlled compartment set to different temperatures ranging from room temperature to 45°C. No separation or precipitation of the emulsion was observed over a period of 2 months.
[0449] The following invention was also tested for stability using yield stress measurements (elastic function, G'(Pa)) over increasing temperatures from 20°C to 60°C (temperature sweep at 1°C per minute at 0.1% deformation) color base formula. The stability of a dye composition is also related to the ability of the composition to suspend dye molecules without becoming unstable with increasing temperature or over time.
