Description

Title of the invention: Cleaning compositions and methods of use Technical field

[0001] The present disclosure relates to compositions for treating keratinous materials, for example for cleaning keratinous materials such as hair, and methods of using the compositions. BACKGROUND

[0002] Conventional personal care cleansing compositions, such as shampoo, body wash, 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 surfactants, or sulfate-containing surfactants, on the skin and body. For example, sulfate-based surfactants tend to dry out hair and skin, strip dyes from color-treated hair, and break down proteins such as keratin, and can cause skin and eye irritation.Additionally, SLES may contain dioxanes, by-products generated in the manufacturing process, which are considered carcinogenic at fairly high levels.

[0003] Silicones are commonly used in personal care products for their conditioning and cosmetic effects. For example, silicones provide a protective layer on hair that makes it easy to detangle and comb, while also providing softness and shine. However, silicones can build up on hair layer by layer, which can weigh hair down and make it greasy. In addition, silicones do not degrade easily, and therefore, their use in personal care products raises environmental concerns. It is therefore desirable to maximize the positive properties provided by silicone and minimize the negative environmental effects and buildup on hair. One way to achieve this is to limit or even eliminate silicones from cleansing compositions, where possible.

[0004] In addition, consumers desire natural compositions for personal care products such as hair and skin cleansing compositions. There is an increased demand for sustainable, safe and environmentally friendly "green" compositions that minimize the use of silicones, e.g. example that are free or essentially free of silicones, as well as other synthetic chemicals for the cleaning and / or care of keratinous materials, including hair and skin, and which nevertheless offer good overall performance and high safety. However, such "green" compositions can be expensive to produce because their materials must come from natural sources such as plants, as opposed to chemicals produced industrially in large volumes.

[0005] Therefore, cleansing compositions that are free of sulfate-based surfactants and substantially free of silicones or that include limited amounts of silicones are increasingly sought after by consumers. However, developing suitable cleansing product formulations without the use of sulfate-based surfactants such as anionic sulfate-based surfactants ("sulfate-free") is challenging. For example, most existing sulfate-free hair cleansing products lather poorly, are opaque, and do not thicken readily. Traditional methods for increasing the viscosity of these formulations, such as incorporating a salt, are not effective with sulfate-free surfactants.

[0006] It is therefore necessary to overcome the challenges described above to develop cleansing compositions, particularly hair cleansing compositions, which meet the increasing consumer demands for natural and sulfate-free cleansing compositions that contain limited amounts of silicone, which also offer satisfactory cosmetic properties.

[0007] It has now been surprisingly discovered that, by using a unique combination of at least one amphoteric surfactant, an anionic surfactant system together with sodium chloride having a specific ratio range of anionic surfactant system to sodium chloride, an alkyl(poly)glucoside and optionally a cationic compound, a cleansing composition, in particular a hair cleansing composition which is free or substantially free of sulfate-based surfactants and minimizes the use of silicones, e.g. is free or substantially free of silicone compounds, can be prepared, the resulting cleansing composition requiring a lower amount of surfactant to produce excellent cleansing and rich, creamy lathering properties, as well as good wet and dry cosmetic properties such as detangling and softness, and is environmentally friendly.

II. Methods

[0146] The present disclosure also relates to methods of cleansing and / or conditioning keratinous materials, including hair, skin and / or scalp, with the compositions disclosed herein. Without limitation, methods of cleansing and / or conditioning keratinous materials according to the disclosure may include applying a sufficient amount, or an effective amount, of a composition disclosed herein to keratinous material, such as hair, skin or scalp, which may be wet, damp or dry, optionally allowing the composition to remain on the keratinous material for a desired period of time, and optionally rinsing the composition from the keratinous material. The composition may optionally be lathered prior to application to the keratinous materials, for example in the hands, or may be lathered while on the keratinous materials.

[0147] Due to the cleansing and conditioning properties of the compositions, in some instances, the compositions may be referred to as a “shampoo,” a “conditioning shampoo,” or an “all-in-one conditioning and shampoo composition.” The compositions may also be both a shampoo and a facial and / or body wash, or a facial and / or body wash. In some embodiments, the compositions of the present disclosure are particularly useful for cleansing and conditioning hair. In addition, the compositions provide a variety of benefits. cosmetic and styling properties desirable for hair, for example, weightless softness, detangling, and anti-frizz. As such, the compositions are useful in methods of cleansing hair, methods of conditioning hair, and methods of imparting softness, detangling, and / or frizz control to hair. Accordingly, the present disclosure encompasses methods of treating hair with the compositions of the present disclosure.

[0148] These methods typically include applying an effective amount of a composition of the instant 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, followed by allowing the hair to air dry or drying the hair with a hair dryer that blows air through the hair and accelerates drying. Typically, the composition is simply left on the hair for a time sufficient to incorporate the composition into the hair, for example, by lathering the composition into the hair with the hands.

[0149] 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 upon rinsing, the dirt, oil, contamination, etc. can be effectively removed from the hair and the conditioning agents of the composition can interact with the hair to condition it. Thus, the composition can be left 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. The composition is then rinsed from the hair, and the hair is allowed to dry.

[0150] As is common when using shampoos and / or conditioning compositions, the hair may be wet or rinsed with water prior to applying a composition described herein. Having water already in the hair may be helpful in creating lather when applying the compositions because the water interacts with the surfactants.

Each of the inventive compositions 1A-1C had a pH in the range of 5-6.5, and viscosities in the range of about 1600-3400 centipoise (cPs) when measured at 25°C using a Brookfield DV-II+ Pro viscosimeter, RV spindle at 10 rpm.

[0183] Each of the inventive compositions 1A-1C demonstrated ease / speed in generating foam, good foam quality (creamy, lush and stable) and an abundance of foam.

[0184] Example 2 - Comparison with a comparative shampoo containing sulfate

[0185] To evaluate performance differences between the sulfate-free cleansing shampoos according to the disclosure and the sulfate-containing shampoos, the inventive composition IB of Table 1 above was tested on human volunteer hair against a commercially available sulfate-containing shampoo (Cl) having the ingredients listed in Table 2.

[0186] Commercial shampoo containing sulfate

[0187] [Tables2] Commercial Product: Cl Ingredients as listed on packaging Aqua / Water / Eau, Sodium Laureth Sulfate, Cocamidopropyl Betaine, Dimethicone, Sodium Chloride, Parfum / Fragrance, Hexylene Glycol, Citric Acid, Sodium Benzoate, Sodium Hydroxide, Amodimethicone, Carbomer, Guar Hydroxypropyltrimonium Chloride, Trideceth-10, Glycerin, Salicylic Acid, Glycol Distearate, Ricinus Communis Seed Oil / Castor Seed Oil, Mica, PEG-100 Stearate, Niacinamide, Panthenol, Phenoxyethanol, Steareth-6, Hexyl Cinnamal, Benzyl Salicylate, Linalool, Benzyl Alcohol, Coco-Betaine, Trideceth-3, Limonene, CI 77891 / Dioxide Titanium Dioxide, Alpha-Isomethyl Ionone, Coumarin, Citronellol, Hydrolyzed Wheat Protein, Hydroxycitronellal, Geraniol, Hydrolyzed Corn Protein, Hydrolyzed Soy Protein, Acetic Acid, Fumaric Acid, Hydrolyzed Wheat Protein Hydroxypropyltrimonium.

[0188] Equal amounts of the inventive and comparative cleansing compositions were applied to opposite halves of a head of wet hair without pre-treatment and worked into a lather with water, the hair was rinsed, and then blow-dried.

[0189] As evaluated, the performance of inventive composition IB resulted in greater softness of lather during application, improved softness on wet hair during and after rinsing, greater ease of blow-drying, and more manageability, body, softness, volume, and sealed ends once dry, compared to composition C1. In addition, inventive composition IB surprisingly demonstrated ease / speed of generating lather, good lather quality (creamy, lush, and stable), and an abundance of lather comparable to that of composition C1, despite the absence of sulfates.

[0190] Based on the above examples, it has been demonstrated that the compositions according to the disclosure surprisingly provide a sulfate-free shampoo with excellent lather and performance properties.

[0191] It will be apparent to those skilled in the art that various modifications and variations may be made to the compositions and methods according to the disclosure without departing from the spirit or scope of the disclosure.
