Description

Compositions and METHODS for cleaning keratinous materials

The present invention relates to compositions for cleaning keratinous materials and methods of using these compositions.

CONTEXT

Conventional personal care cleansing compositions such as shampoo, shower gel, facial cleanser, hand soap, etc. typically use sulfate-based surfactants such as sodium lauryl sulfate (SLS) or sodium laureth ether sulfate (SLES). These surfactants are commonly used because they have good foaming and cleansing properties, can be thickened easily, and are relatively inexpensive. However, there is growing market concern about the negative effects of these or other sulfate-based or sulfate-containing surfactants on the skin and body. For example, sulfate-based surfactants tend to dry out hair and skin, strip dye from colored hair, and break down proteins such as keratin, and can cause skin and eye irritation. Additionally, SLES may contain dioxanes, by-products generated during the manufacturing process, which are considered carcinogenic at fairly high levels.

Additionally, silicones are commonly used in personal care products for their conditioning and cosmetic effects. For example, silicones form a protective layer on the hair that makes it easy to detangle and comb, and gives it smoothness and shine. However, silicones can build up on hair layer by layer, which can weigh hair down and make it greasy. Additionally, silicones do not degrade easily and therefore their use in personal care products raises environmental concerns.

Additionally, consumers desire natural compositions for personal care products, such as hair and skin cleansing compositions. There is an increased demand for durable, safe and environmentally friendly "green" compositions which are free or substantially free of silicones, as well as other synthetic chemical materials for cleaning and/or caring for keratinous materials, including including hair and skin, while providing desirable overall good performance and high safety. However, these "green" compositions can be expensive to produce because their materials must come from natural sources such as plants, as opposed to high-volume industrial chemicals. In addition, it is often difficult to achieve an acceptable balance of performance properties of cleaning compositions when using products of natural origin. For example, adding a particular component to a cleaning composition will often enhance one desired property at the expense of another desired property.

This is why cleaning compositions free of surfactants based on sulphate and/or silicones are increasingly popular with consumers. However, it is difficult to develop suitable formulations of cleaning products without using sulfate-based surfactants, such as anionic sulfate-based surfactants and/or silicones ("sulfate-free" and/or "silicone-free". "). For example, most existing sulfate-free hair cleansing products lather poorly, are opaque, and don't thicken easily. Traditional methods of increasing the viscosity of these formulations, such as incorporating a salt, are not effective with sulfate-free surfactants.

It is therefore necessary to overcome the difficulties described above in order to develop compositions for cleaning keratinous materials which meet the growing consumer demand for natural, sulfate-free and silicone-free cleaning products, and which give keratinous materials satisfactory cosmetic properties.

It is now surprising to find that by using a synergistic combination of components, it is possible to prepare a composition for cleaning keratinous materials which is free or essentially free of sulphate-based surfactants and/or silicone compounds, which has excellent foaming and cleansing properties, as well as good cosmetic properties, and is environmentally friendly.

1. Processes

The present disclosure also relates to methods for cleansing and/or conditioning keratinous materials, in particular the skin, hair and/or scalp, with the compositions disclosed herein. Without limitation, methods for cleansing and/or conditioning keratinous materials in accordance with the present disclosure may include applying a sufficient amount, or an effective amount, of a composition disclosed herein to a keratinous material, such as such as skin, hair or scalp, which may be damp, wet or dry, optionally allowing the composition to remain on the keratinous material for a desired length of time, and optionally rinsing the composition from the keratinous material. The composition may optionally be lathered before being applied to the keratinous materials, for example in the hands, or may be lathered while on the keratinous materials.

Due to the cleansing and conditioning properties of the compositions, they may in some cases be referred to as "shampoo", "conditioning shampoo" or "all in one conditioner and shampoo". The compositions can also be face and/or body washes, or both hair and face and/or body washes. In certain embodiments, the compositions of the present disclosure are particularly useful for cleansing and conditioning hair. In addition, the compositions provide a variety of desirable cosmetic and styling benefits to the hair, for example, smoothness without weighing down, detangling and anti-frizz. As such, the compositions are useful in methods of cleansing hair, methods of conditioning hair, and methods of imparting smoothness to hair, detangling, and/or controlling frizz. Accordingly, this disclosure encompasses methods of treating hair with the compositions of this disclosure.

These methods generally involve applying an effective amount of a composition of the present disclosure to the hair, allowing the composition to remain on the hair for a period of time, and then rinsing the composition from the hair. Usually, the composition is simply allowed to remain on the hair for a sufficient period of time to incorporate the composition into the hair, for example, by lathering the composition into the hair with the hands.

The duration is sufficient for the composition to interact with the hair and any dirt, oil, contamination, etc. that may exist on the hair, so that when rinsing, dirt, oil, contamination, etc. can be effectively removed from the hair and that the conditioning agents of the composition can interact with the hair to condition it. Thus, the composition can stay on the hair for about 5 seconds to about 30 minutes, about 5 seconds to about 15 minutes, about 5 seconds to about 10 minutes, about 5 seconds to about 5 minutes, about 10 seconds to about 5 minutes, or about 10 seconds to about 3 minutes.

As is common when using shampoos and/or conditioning compositions, hair may be wet or rinsed with water prior to application of a composition disclosed herein. The presence of water in the hair can be helpful in creating lather when applying the compositions, as water interacts with surfactants.

Examples

The following examples are intended to be non-limiting and explanatory in nature only. In the examples, the amounts are expressed as a percentage by weight (% by weight) of the active materials, based on the total weight of the composition.

Example 1 - Cleaning compositions

The following inventive compositions were prepared according to the formulations shown in Table 1 below.

INCI name Compositions inventive 1A 1B 1 C 1D DISODIUM COCOAMPHODIACETATE 4.00 4.00 5.04 4.00 COCAMIDOPROPYL BETAINE 3.23 3.23 8.66 3.23 COCO-BETAINE 1.56 1.56 - 1.56 CAPRYLYL/CAPRYL GLUCOSIDE 3.0 3.0 3.9 3.0 SODIUM COCOYL ISETHIONATE - - - 2.0 SODIUM C14-16 OLEFIN SULFONATE 0.87 - 2.66 - SODIUM METHYL COCOYL TAURATE - 0.87 - - STEARAMIDOPROPYL DIMETHYLAMINE 2.5 2.5 2.0 2.5 XANTHAN GUM 0.42 0.42 0.45 0.42 CITRIC ACID 0.96 0.95 0.94 0.85 ADDITIVES (perfume, preservatives, thickeners) 1.64 1.63 2.30 1.90 SOLVENT (water + non-aqueous solvents) QS QS QS QS

Each of the inventive compositions 1A through 1D were prepared by first mixing the solvents and the polysaccharide thickener in a homogenizer for two minutes. The speed was then reduced, the temperature increased and the fatty amine was added. Once the fatty amine was well incorporated, the speed was increased and the disodium cocoamphodiacetate was added, and mixing continued for 15 minutes. The temperature was again reduced and the other ingredients were added in stages, until the final composition was homogeneous.

Inventive compositions 1A-1C were semi-transparent and stable. They had a pH of approximately 5.29, 5.42 and 5.4, respectively. Their viscosity was about 10 seconds, 10 seconds, and 36 seconds of flow time, respectively, when measured using the Ford Cup 8, which roughly matches the viscosity in Brookfield (pin 4, 20 rpm) of 3700 cPs, 5100 cPs and 16,500 cPs.

Example 2 - Foaming Analysis

A foaming study was conducted to analyze the foaming properties of inventive compositions 1A-1C of Table 1, in comparison to a commercially available shampoo that contained both sulfate-based surfactants (e.g., laureth sulfate sodium) and silicones (comparative composition C1).

Foam analysis was performed on a foam analyzer as follows: a) Prepare a 10% solution for each sample of test composition by diluting the composition to 10% with tap water at 25°C ; b) vigorously agitate the 10% solution of each test composition sample using a high speed mixer for less than 15 seconds; c) add the solution to the cylinder of the foam analyzer; d) agitate the solution for 15 seconds to generate foam; and e) after 15 seconds, stop shaking and monitor the height of the foams generated, the height of the liquid ( ie , drainage of the liquid from the foams) in the bottom of the cylinder, and the total height of the foam and the liquid in the bottom . Furthermore, the structures of the foam generated by the inventive compositions 1A to 1C and the comparative composition C1 were analyzed.

Figures 1 to 3 are graphs illustrating the foaming performance of Inventive Compositions 1A to 1C measured during the foam analysis. There is a graph illustrating the foaming performance of comparative composition C1 during the foaming analysis. There is a graph comparing the height of foams generated by Inventive Compositions 1A-1C and Comparative Composition C1 over a period of time. As shown in Figures 1 to 5, the foams generated by the three inventive compositions 1A to 1C reached a height of between 90 mm and 100 mm in approximately 16 seconds, and remained at this height for more than approximately 250 seconds. On the other hand, while the foam generated by the comparative composition C1 reached a height of almost 100 mm in about 16 seconds, it quickly decreased to reach a level of almost 80 mm in a few seconds. The foam of Comparative Composition C1 began to turn into a liquid, the height of the foam fell below 80 mm in 160 seconds, and its liquid level began to rise accordingly. The liquid height of the three inventive compositions 1A-1C also remained at about the same level. The results showed that the three inventive compositions 1A to 1C improved their foaming performances compared to the comparative composition C1, in particular with regard to the instantaneous foaming, the abundance and the stability of the foam.

In addition, the structures of the foams generated by Inventive Compositions 1A to 1C and Comparative Composition C1 were studied. In this study of foam structure, the number of bubbles (number of bubbles/mm ² ) and the average bubble area (MBA) (size of bubbles) were measured. Air bubble size structure data and change in bubble size over time indicated that the foams formed by the Inventive Compositions were creamy and stable.

FIGS. 6 to 9 are graphs illustrating the number of bubbles/mm ² and the average bubble area (MBA) of the foams generated by the compositions 1A to 1C and C1. As shown in FIGS 6-9, the number of bubbles/mm ² of compositions 1A to 1C remains around 1000 over an extended period, while that of comparative composition C1 is around 900. The structure data shows that for inventive compositions 1A to 1C, the MBA remains above 1000 or increases to more than 1000 over time. In contrast, the MBA for comparative composition C1 decreases over time and then begins to increase at the end of the trial period. The results showed that compared to the foams generated by Comparative Composition C1, the foams generated by the compositions disclosed herein were surprisingly creamy and stable. Thus, the cleaning compositions according to the disclosure have excellent foaming properties despite the absence of sulphate-based surfactants.

Example 3 – Performance evaluation

A comparative study was conducted to evaluate the performance of inventive compositions 1A-1C, prepared according to the formulas in Table 1, when used as shampoos, compared to the commercially available shampoo used in Example 2, c ' i.e. the comparative composition C1. The study was performed on the hair of mannequins, hair samples and heads of individual volunteers.

Mannequin test

In the mannequin test, the long, straight, bleached, damp hair of one half of the mannequin models' heads was treated with one of the inventive compositions 1A to 1C, and the other half of the head was treated with the comparative composition C1, side by side. About 5 grams of one of Inventive Compositions 1A-1C was applied to half of a model's hair head and evenly distributed with fingers and lathered up. The same amount of comparative composition C1 was then applied to the other half of the model's hair and distributed evenly with the fingers, then lathered up. The inventive compositions and the comparative composition were left on the hair for approximately 2 minutes, followed by thorough rinsing. After rinsing the compositions from the hair, the quality and quantity of lather and the conditioning effects were evaluated.

According to the experts' evaluation, the overall performance of each of the inventive compositions 1A to 1C was similar to that of the comparative composition C1, without the drawbacks of a sulfate-based shampoo.

Hair strand test

In the hair strand test, a medium bleached hair sample was used. In particular, 0.5 grams of each sample of Inventive Compositions 1A-1C and Comparative Composition C1 was applied to the wet hair sample and distributed evenly with the fingers, then allowed to lather and rinse. After rinsing the compositions from the hair, the hair was combed while wet, dried and styled. The hair strand test was performed on both damp and dry hair.

According to the experts' evaluation, the overall performance of each of the inventive compositions 1A to 1C was similar to that of the comparative composition C1, without the drawbacks of a sulfate-based shampoo.

In-vivo test

In the in vivo test, the inventive compositions were tested and compared to the comparative composition on the heads of 3 individual volunteers using methods similar to those applied to mannequin models.

According to the experts' evaluation, the overall performance of each of the inventive compositions 1A to 1C was similar to that of the comparative composition C1, without the drawbacks of a sulfate-based shampoo.

Based on the examples above, the compositions of the disclosure have been shown to exhibit excellent foaming and performance properties compared to compositions which are not free or substantially free of anionic sulfate surfactants.

It will be apparent to those skilled in the art that various modifications and variations may be made to compositions and methods based on the disclosure without departing from the spirit or scope thereof. It is therefore intended that the disclosure cover such modifications and variations and their equivalents.
