The present disclosure relates to silicone based cosmetic compositions comprising a silicone amine and an anionic silicone, and methods for using the cosmetic compositions. The present disclosure additionally relates to silicone based coloring compositions and uses thereof for artificially coloring and/or preserving artificial color in/on a keratinous substrate.
An essential constituent of the body is keratin, which plays a decisive role in determining the properties of hair, skin, scalp, lips and nails. The keratin is often affected or damaged by external influences and/or adverse environmental conditions. For example, high or low humidity conditions can adversely affect the skin in terms of moisturization, suppleness and smoothness. Other external influences such as solar irradiation (irradiation with UV light), air pollutants, and mechanical or physical rubbing/scrubbing of the skin can also damage or irritate the skin, thereby affecting the condition and appearance of the skin and/or scalp.
Solar irradiation (irradiation with UV light) can also lead to a reduction in the mechanical strength of the hair and to a bleaching of the natural and artificial hair color. Chlorinated water in swimming pools etc. causes oxidation of the keratin, which can lead to a loss of protein. Moreover, human hair is often subjected to chemical hair treatments, such as treatments with permanent waving or hair straightening compositions, hair colorants, bleaches, shampoos, etc. Additionally, hair is subjected to regular washing, combing, brushing and blow drying. Just like UVA irradiation, these treatments can change the original properties of the hair, damage the hair and/or produce color-changing effects on the hair. For example, bleaching generally leads to hair damage, where the melanine pigments in the cuticle cells and the cortex cells of the hair are degraded by complex chemical reactions.
Damaged hair becomes rough, brittle and more difficult to manage, comb and/or disentangle. Loss of shine can also result from exposure to UV light and high humidity and the artificial color on hair fades from exposure to UV light and washing. Additionally, the noxae involved in hair chemical treatments cannot be completely eliminated after the first rinsing so that the result is ultimately insidious oxidation and consequently the specified hair damage and/or undesirable color changes in both dyed and naturally colored hair.
In addition, high or low humidity conditions result in reduced manageability making it more difficult to comb or groom and style or shape the hair. Under high humidity conditions, hair can become frizzy, more porous and more sensitive to the effect of moisture and therefore requires longer drying times. Its resistance and tear strength are reduced and its extensibility is altered. Under low humidity conditions, the hair becomes dry. It is thus desirable to apply a composition on the hair which will help keep moisture out of the hair or help retain moisture in the hair at various humidity conditions.
It has been surprisingly and unexpectedly found that the silicone based cosmetic compositions of the present disclosure provide cosmetic benefits to hair and skin and can be used for beneficially coating, treating, protecting and/or improving the condition and quality of hair and skin.
Imparting a color change or color effect to hair can be done using permanent, semi-permanent, and temporary hair coloring products. Many permanent hair coloring products use oxidative hair color that bleaches the melanin found in the hair shaft as well as imparting color. Activated peroxide in the oxidative dye composition provides a bleaching effect while the oxidative dye molecules penetrate the hair shaft and polymerize therein. While hair that is oxidatively colored provides a certain permanence, re-coloring every four to six weeks may be necessary due to new hair growth. Oxidative hair color is sold in the form of a two component kit. The reactivity of the oxidative dye and the oxidizing agent means that the two ingredients cannot be formulated into a single composition. Rather, the kits have one container filled with an aqueous composition in the liquid, gel, or cream form that contains the oxidative dyes and a second container filled with a developer composition that contains an oxidizing agent, usually hydrogen peroxide. The two containers are combined immediately prior to use and applied to hair. The oxidizing agent and dyes react when mixed. The mixture is applied to hair for an appropriate period of time, generally 20 to 60 minutes, then rinsed off with water. Permanent hair color is very versatile and long lasting in the colors and effects it provides, and it is only with permanent hair color that one can color hair to a shade that is lighter than the natural color.
Semi-permanent hair color generally provides more lasting color than temporary dyes but without the permanence and commitment of oxidative color. Semi-permanent color is a single component product containing direct dyes. Many of such products contain two types of dyes: one of smaller molecular size (such as nitrophenylene diamines and nitroaminophenols) that are capable of penetrating the hair shaft and being retained within. While smaller molecular size permits these dyes to more easily penetrate the hair shaft. The second type of dye used in semi-permanent hair color has a larger molecular size and is too large to penetrate the hair shaft of normal virgin hair. However, such larger dye molecules easily penetrate porous and damaged hair where they are often retained due to their larger size. Accordingly, the balancing of the small and large dye molecules found in many semi-permanent products provides color with a uniform and durable effect. Semi-permanent color provides excellent gray blending and good color retention.
Temporary hair color may employ pigments and natural colorants (e.g., vegetable-derived) is often found in the rinse form, and typically lasts for one shampoo. Such hair color is often used when special effects are desired. Temporary color simply coats the hair shaft with colorants that are too large to penetrate its outer surface. Minor penetration of the hair shaft may occur in individuals with damaged or porous hair, but such color application rarely lasts through more than one or two shampoos.
Thus, it is an object of the present disclosure to provide a silicone based composition for treating keratinous substrates such as the hair, skin and/or the scalp wherein the composition can provide cosmetic benefits to and help protect the keratinous substrates from external influences or improve the condition of the keratinous substrates. It is an additional object of the present disclosure to provide hair coloring compositions and methods for coloring hair including methods for simultaneously washing and depositing color onto the hair.

Three IHIP Regular Bleached hair swatches (1″ width, 5″ length) were treated with the following compositions.
The initial wet combing of untreated control and test hair swatches was performed using the Instron, measuring break energy (g-in). 1 gram of Control composition and 1 gram of Test composition were thoroughly massaged into the control and test hair swatches and the hair swatches were allowed to stand for 5 minutes. The hair swatches were wetted and 0.4 grams of shampoo per gram of swatch (SLES-2 15%, pH=6) were massaged into the control and test hair swatches for 30 seconds. The hair swatches were then rinsed in water for 15 seconds (80 gph, 32° C.), The final Break Energy was measured and statistical analyses were performed on the measurements (t-test).
The results showed that for the hair treated with the Test composition, there was a statistically significant change from initial to final wet combing measurements, as shown by Break Energy values of 513.14 and 198.96, respectively. Lower break energy values correspond to less energy required to comb the hair. Therefore, the treatment of the hair with the disclosed complex significantly improved the wet combing properties of the hair as compared to those of the untreated hair as shown by the reduced force in combing of about 2.5 times.
In addition, the % change in Break Energy between the hair treated with the Test composition and hair treated with the Control composition was −58.1 and −10.48, respectively. The more negative the change, the smoother the hair. Therefore, the hair treated with the disclosed complex exhibited significantly better wet combing properties compared to the hair treated with the control composition, as shown by an improvement in wet combing of 5.5 times.
Six IHIP Platinum Bleached hair swatches (1 cm width, 19 cm length) were dyed with Redken Hi Fusion R with Pro-Oxide 20 vol. developer at 1:1 ratio. The hair swatches were then shampooed 6 times with the following shampoos.
Initial LAB values of hair swatches using Konica Minolta Spectrophotometer were measured. 0.4 grams of Test shampoo and Control shampoo were massaged into Test and Control hair swatches for 15 seconds. The hair swatches were then rinsed in water for 15 seconds (80 gph, 32° C.). The shampoo and rinse cycle was repeated 6 times. The hair swatches were completely dried and the final LAB values were calculated. The ΔE and %ΔL values were calculated.
The %ΔL results are as shown below.
The lower the %ΔL value, the darker the color of the hair. Using an ANOVA statistical test, the %ΔL value for Test shampoo was found to be significantly lower than %ΔL value for the Control shampoos 1, 2, and 3. Therefore, the disclosed composition, when present in the shampoo, helped retain the color on the hair after shampooing and washing.
Six swatches of regular bleached hair from International Hair Importers “IHIP” (5 mm width, 19 cm length) were dyed with the following formulas, each formula mixed 1:1 with a 20 volume developer composition (6% hydrogen peroxide), 20 g of mixture per swatch, for 40 minutes of processing time.
After rinsing the hair for 1 minute, the swatches were shampooed once with sodium lauryl ether sulfate-2 (SLES-2), 15% by weight in water (pH=6, 1 g/g hair). Initial and final L*A*B* values were measured using the Konica Minolta Spectrophotometer; ΔE and % ΔL were calculated, and a statistical analysis test (ANOVA) was performed.
The ΔE and %ΔL results are as follows:
The higher the ΔE value, the greater the overall change in color of the hair. The lower the %ΔL value, the darker the color of the hair after dyeing. According to the ANOVA test, the overall color changes, ΔE, for the Test formula A and Test formula B were statistically significantly greater than the ΔE, for the Control formula. In addition, the %ΔL value for the Test formula A and Test formula B were statistically significantly lower than the %ΔL value for the control formula. Furthermore, Test formula B performed better than Test A with respect to both ΔE and %ΔL comparisons with the control formula.
Therefore, the results show that the hair swatches dyed with the formulas containing the silicone amine/anionic silicone combination were significantly darker in color and had significantly greater color intensity compared to the swatches dyed with the control formula. This indicates significantly better color deposit using the compositions of the present disclosure compared to the traditional hair color (control formula).

Traditional hair dyes are usually processed for 30 minutes (+/−10 minutes). Reducing the processing time drastically to 10 minutes (+/−5 minutes) would be more desirable, however the efficiency of the resulting color would be sacrificed, unless a high load of dye compounds are added to compensate for the color in conventional methods. By using the composition of the present disclosure, reducing the processing time did not adversely affect the efficiency of the resulting color, even when the levels of the dye compounds used were consistent with those in traditional hair dyes.
A swatch each of IHIP 90% Gray Permed, 90% Gray Unpermed, and Regular Bleached hair swatches was dyed with the following formulas below for 5, 10, and 15 minute processing times.
The hair swatches were rinsed for 1 min (80 gph, 32° C.) and dried completely. The final L*A*B* values were measured using the Konica Minolta Spectrophotometer, and ΔE values between control and test formulas were calculated. Results are as follow:
5 minute processing time, 90% gray permed hair had ΔE of 14.95 and 90% gray unpermed hair had a ΔE value of 14.55.
10 minute processing time, 90% gray permed hair had ΔE of 11.06 and 90% gray unpermed hair had a ΔE value of 10.70.
15 minute processing time, 90% gray permed hair had ΔE of 9.63 and 90% gray unpermed hair had a ΔE value of 9.86.
A high ΔE value indicates a greater color change, and a ΔE>3 is accepted as significant color difference. The ΔE values and visual observations of the swatches show that the swatches dyed with the formulas containing the silicone amine/anionic silicone combination had significantly greater overall color change, by having more intense and darker color compared to the control formula.
Therefore, the formulas containing the silicone amine/anionic silicone combination provided better color deposit than the traditional dye at shorter processing times of 5, 10, or 15 minutes.
Six IHIP Platinum Bleached hair swatches (2.5 g) were dyed with the following formulas below for 30 minutes of processing time.
The hair swatches were rinsed for 1 min (80 gph, 32° C.) and dried completely. The initial and final L*A*B* values were measured using the Konica Minolta Spectrophotometer, and ΔE was calculated.
After treatment, the ΔE values for Test formula and Control formula were 50.222 and 41.278, respectively. The higher the ΔE value, the greater the overall change in color of the hair. In addition, %ΔL values for Test formula and Control formula were −57.845 and −70.513, respectively. The lower the %ΔL value, the darker the color of the hair. According to a statistical t-Test, the Test formula performed statistically significantly better than the Control formula in terms of both A E and %ΔL comparisons. Therefore, the addition of the silicone amine/anionic silicone combination to the dye composition helped increase the color deposit and boost the intensity of the color on the hair, despite the dilution of the dye concentration by 20% in the test formula.
A swatch each of IHIP Platinum Bleached hair swatches (2.5 g) was dyed with the following formulas below for 30 minutes of processing time.
The hair swatches were rinsed for 1 min (80 gph, 32° C.) and dried completely. The final L*A*B* value was measured using the Konica Minolta Spectrophotometer, and ΔE was calculated between the Test formula and Control formula.
After treatment, the ΔE value for Test formula vs. Control formula was 18.03. A high ΔE value indicates a greater color change, and a ΔE>3 is accepted as significant color difference. The ΔE value and visual observation of the swatches show that the swatches dyed with the dye composition containing the silicone amine/anionic silicone combination had a significantly better overall color change, by having a more intense and darker red color. Therefore, the addition of the silicone amine/anionic silicone combination to the dye composition helped boost the intensity of the color on the hair, despite the dilution of the dye concentration by 20% in the test formula.
IHIP Platinum Bleached hair swatches (1 cm width, 13 cm length) were dyed with the following formulas below, for 30 minutes of processing time (three swatches per formula).
The hair swatches were rinsed for 2 minutes (100 gph, 32° C.) and dried completely. The final L*A*B* values were measured using the Konica Minolta Spectrophotometer; ΔE between control vs. test were calculated.
The results showed that hair dyed with the formula containing the silicone amine/anionic silicone combination had a more dark red color than the hair dyed with the control formula. The average ΔE value between the control and the test was 20.28, corresponding to a significantly higher overall change in color for the swatches dyed with the test formula. Therefore, the formula containing the silicone amine/anionic silicone combination provided a significantly more intense color to the hair compared to the traditional hair color base.
Six IHIP Platinum Bleached hair swatches were dyed with the following formulas below, for 30 minutes of processing time.
The hair swatches were rinsed for 1 minute (80 gph, 32° C.) and dried completely. Initial L*A*B* values were measured using the Konica Minolta Spectrophotometer. The swatches were then shampooed with 10% SLES-2 (15 seconds wash, 10 seconds rinsing). The shampooing and rinsing steps were repeated for a total of seven cycles of shampooing and rinsing. The swatches were dried completely and final L*A*B* values were measured. The ΔE and % change in L values (%ΔL) were calculated.
The results showed that hair dyed with the formula containing the silicone amine/anionic silicone combination had retained more color than the hair dyed with the control formula. Control and Test swatches had ΔE values of 20.52 and 27.98, respectively, after 7 shampoo/rinse cycles. The higher the ΔE, the greater the overall change in color of the hair. In addition, Control and Test swatches had %ΔL values of −22.89 and −33.4, respectively, after 7 shampoo cycles. The lower the change in L value, the darker the color of the hair. Therefore, the addition of the silicone amine/anionic silicone combination to the direct dye composition helped the dyed hair to substantially retain its color even after several shampoo/rinse cycles.
