Description

Examples 1 and 2, Comparative Examples C1 to C4

Hair Combability

[0238] Hair combability test measures the force required for standard comb to pass through a hair tress. The parameter measured is: [0239] Total work: the total energy required during the whole combing process (Joules) [0240] Peak of Force: the maximum force registered during the combing process (gmf)

[0241] Since the hair surface characteristics are dependent on the cuticle/comb interaction, hair in wet or dry situations can change the values in the measurements. Caucasian bleached tresses were treated 5 times with the samples. Test in wet condition was performed. The tresses were dried at controlled temperature and humidity (22° C.+/−2° C. and 55% RH) overnight before evaluation in dry condition. Comparisons among the samples were made. Statistical analysis was performed with analysis of variance, followed by post-test of Tukey, considering 95% of confidence interval. The blends were incorporated at specific concentrations in shampoo and conditioner formulations: example 1=0.1% b.w. in shampoo and 0.5% b.w. in conditioner; example 2=1.0% b.w. in shampoo and 1.0% b.w. in conditioner. Pure ingredients were incorporated at half of its respective blend, i.e.: SymMollient S=0.05% b.w. in shampoo and 0.25% b.w. in conditioner; Biobranil Oily=0.05% b.w. in shampoo and 0.25% b.w. in conditioner; Hydrolite 5=0.5% b.w. in shampoo and 0.5% b.w. in conditioner; and finally Biobranil PGW=0.5% b.w. in shampoo and 0.5% b.w. in conditioner. The results are compiled in Table 1. Examples 1 and 2 are according to the invention, examples C1 to C4 serve for comparison. The values express the percentage of improvement when compared to placebo.

Luster Evaluation

[0243] Luster evaluation test analyzes luster effect by the interactions of the light with the hair surface. The measurement is made using SAMBA system and the results are expressed by: [0244] Shine: intensity of the reflection of the light at the hair surface—first reflection of the light. [0245] Luster: parameter calculated from values of shine, chroma and diffused light to express the luster effect seen by an observer.

Volume/Frizz Control Assessment

[0252] Volume is the gain of body in a hair tress due to its humidity exposure or mechanical actions such as combing or friction of fibers. Frizz is the bristling of some fibers of hair that get apart from the tress body (fly-away effect). Anti-frizz/volume test measures the variation in the shape of the tress after exposure to a high humidity environment, for a controlled period of time. The parameter measured is: [0253] Number of Pixels in the Image

[0254] Afro virgin tresses were treated 5 times with the samples and dried at controlled temperature and humidity (22° C.+/−2° C. and 55% RH) overnight before evaluation. They were straightened with a flat iron. Images at initial time were captured. Tresses were left for 4 h at 70% relative humidity environment. Images at final time were captured. Comparisons between initial and final time were made. Statistical analysis was performed with analysis of variance, followed by post-test of Tukey, considering 95% of confidence interval. The blends were incorporated at specific concentrations in shampoo and conditioner formulations: example 1=0.1% b.w. in shampoo and 0.5% b.w. in conditioner; example 2=1.0% b.w. in shampoo and 1.0% b.w. in conditioner. Pure ingredients were incorporated at half of its respective blend, i.e.: SymMollient S=0.05% b.w. in shampoo and 0.25% b.w. in conditioner; Biobranil Oily=0.05% b.w. in shampoo and 0.25% b.w. in conditioner; Hydrolite 5=0.5% b.w. in shampoo and 0.5% b.w. in conditioner; and finally Biobranil PGW=0.5% b.w. in shampoo and 0.5% b.w. in conditioner The results are compiled in Table 4.

Fluorescence Microscopy

[0256] Rhodamine B is cationic and presents affinity with damaged regions of the hair. Tresses are treated and then soaked in solution with Rhodamine B. It reacts with the negative sites of damaged hair. A fluorescent complex is formed in the hair fiber and can be detected when exposed to a fluorescence microscope. After capturing images in the microscope, the intensity of luminance in the images is quantified by image analysis.

[0257] The parameter measured is luminance intensity as expression of damage. A treatment that generates images less fluorescents expresses the effect of penetration of the formulation. Caucasian bleached tresses were treated 5 times with the samples. The tresses were dried at controlled temperature and humidity (22° C.+/−2° C. and 55% RH) overnight before evaluation. Microscopic images were made and then analyzed to calculate the luminance intensity. Comparisons between treated and untreated hair were made. Statistical analysis was performed with analysis of variance, followed by post-test of Tukey, considering 95% of confidence interval. The blends were incorporated at specific concentrations in shampoo and conditioner formulations: example 1=0.1% b.w. in shampoo and 0.5% b.w. in conditioner; example 2=1.0% b.w. in shampoo and 1.0% b.w. in conditioner. Pure ingredients were incorporated at half of its respective blend, i.e.: SymMollient S=0.05% b.w. in shampoo and 0.25% b.w. in conditioner; Biobranil Oily=0.05% b.w. in shampoo and 0.25% b.w. in conditioner; Hydrolite 5=0.5% b.w. in shampoo and 0.5% b.w. in conditioner; and finally Biobranil PGW=0.5% b.w. in shampoo and 0.5% b.w. in conditioner.

Swelling Test

[0259] Through diameter measurements, it is possible to determine the level of swelling of a fiber of hair over time. The laser measures the variation in the fiber diameter as it absorbs water over a pre-determined time. According to the fiber condition or the film covering its surface, the level of swelling may change. The more damaged the hair, more hydrophilic it is and, consequently, more swelling is noticed since most of the hair damages take the lipids, ceramides and other hydrophobic substances away from the hair. The parameter measured is: [0260] % of swelling as % of the fiber diameter variation.

[0261] Caucasian bleached tresses were treated 5 times with the samples. The tresses were dried at controlled temperature and humidity (22°C.+/−2° C. and 55% RH) overnight before evaluation. Comparisons among the samples were made. Statistical analysis was performed with analysis of variance, followed by post-test of Tukey, considering 95% of confidence interval. The blends were incorporated at specific concentrations in shampoo and conditioner formulations: example 1=0.1% b.w. in shampoo and 0.5% b.w. in conditioner; example 2=1.0% b.w. in shampoo and 1.0% b.w. in conditioner. Pure ingredients were incorporated at half of its respective blend, i.e.: SymMollient S=0.05% b.w. in shampoo and 0.25% b.w. in conditioner; Biobranil Oily=0.05% b.w. in shampoo and 0.25% b.w. in conditioner; Hydrolite 5=0.5% b.w. in shampoo and 0.5% b.w. in conditioner; and finally Biobranil PGW=0.5% b.w. in shampoo and 0.5% b.w. in conditioner.
