Description

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

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

[0002] 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 increasing concern in the market about the negative effects of these or other sulfate-based surfactants, or surfactants containing sulfates, on the skin and body. For example, sulfate-based surfactants tend to dry out hair and skin, strip color from colored hair, and break down proteins such as keratin, and can cause skin and eye irritation.In addition, 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 the hair, making it easier to detangle and comb, while also giving it softness and shine. However, silicones can build up on the hair layer by layer, which can weigh it down and make it look 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 effects on the environment and on hair buildup. One way to achieve this is to limit, or even eliminate, silicones from cleansing formulations wherever possible.

[0004] Furthermore, consumers want natural compositions for personal care products such as hair and skin cleansers. There is an increasing demand for sustainable, safe, and environmentally friendly "green" compositions that minimize the use of silicones, by Examples include products that are free or essentially free of silicones and other synthetic chemicals used for cleaning and / or caring for keratinous materials, including hair and skin, yet still offer desirable overall performance and high safety. However, such "green" formulations can be expensive to produce because their ingredients must come from natural sources such as plants, as opposed to industrially produced, large-scale chemicals.

[0005] Consequently, cleansing compositions that are free of sulfate-based surfactants and essentially free of silicones, or that contain 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 (“sulfate-free”) surfactants, presents a challenge. For example, most existing sulfate-free hair cleansers lather poorly, are opaque, and do not thicken easily. 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 in order to develop cleansing compositions, in particular cleansing compositions for hair, which meet the growing consumer demands for natural and sulfate-free cleansing compositions which contain limited amounts of silicone, which also offer satisfactory cosmetic properties.

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

II. Processes

[0133] This 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, the methods of cleansing and / or conditioning keratinous materials according to the disclosure may include applying a sufficient, 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 duration, and optionally rinsing the composition from the keratinous material. The composition may optionally be foamed before application to the keratinous materials, for example, in the hands, or may be foamed while on the keratinous materials.

[0134] Due to the cleansing and conditioning properties of the compositions, in some cases 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 face and / or body wash, or a face and / or body wash. In some embodiments, the compositions of this disclosure are particularly useful for cleansing and conditioning hair. In addition, the compositions provide a variety of desirable cosmetic and styling benefits for hair, for example, softness without weighing it down, detangling, and anti-frizz. As such, the compositions are useful in hair cleansing processes, hair conditioning processes, and processes for imparting softness to hair. detangling and / or frizz control. Therefore, this disclosure includes hair treatment processes using the compositions described in this disclosure.

[0135] These processes typically include applying an effective amount of an instant-release composition to the hair, allowing the composition to remain on the hair for a certain time, and then rinsing the composition from the hair, followed by allowing the hair to air dry or drying the hair with a hairdryer that blows air through the hair and accelerates drying. Usually, the composition is simply left on the hair for a sufficient time to incorporate it into the hair, for example, by lathering the composition in the hair with the hands.

[0136] The duration is sufficient for the composition to interact with the hair and any dirt, oil, contamination, etc., that may be present on the hair, so that upon rinsing, the dirt, oil, contamination, etc., can be effectively removed from the hair and the conditioning agents in the composition can interact with the hair to condition it. Thus, the composition can be left on the hair for approximately 5 seconds to approximately 30 minutes, approximately 5 seconds to approximately 15 minutes, approximately 5 seconds to approximately 10 minutes, approximately 5 seconds to approximately 5 minutes, approximately 10 seconds to approximately 5 minutes, or approximately 10 seconds to approximately 3 minutes. The composition is then rinsed from the hair, and the hair is allowed to dry.

[0137] As is common practice when using shampoos and / or conditioning compositions, hair may be wetted or rinsed with water before applying a composition described in this document. Having water already present in the hair can be helpful in creating lather when applying the compositions because the water interacts with the surfactants.
