Description

cleaning compositions and methods of use

The present disclosure relates to compositions for the treatment of keratinous materials, for example for cleaning keratinous materials such as hair, and methods of using the compositions.

CONTEXT

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 cleaning 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 colored hair, and break down proteins such as keratin, and can cause skin and eye irritation. Additionally, SLES may contain dioxanes, byproducts generated in the manufacturing process, which are considered carcinogenic at fairly high levels.

Silicones are commonly used in personal care products for their conditioning and cosmetic effects. For example, silicones provide a protective layer on the hair that makes it easy to detangle and comb, while providing softness and shine. However, silicones can build up on hair layer by layer, which can weigh hair down and make it oily. Additionally, 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 build-up on the hair. One way to achieve this is to limit or even eliminate silicones from cleaning compositions, wherever possible.

Additionally, consumers want 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, for example which 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, desirable 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 high-volume industrially produced chemicals.

Therefore, cleaning compositions that are free of sulfate surfactants and substantially free of silicones or that include limited amounts of silicones are increasingly sought after by consumers. However, developing suitable cleaning product formulations without the use of sulfate-based surfactants such as anionic sulfate-based surfactants (“sulfate-free”) is 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.

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

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

Accordingly, in some cases the viscosity of a composition disclosed herein may be from about 800 cPs to about 20,000 cPs, such as from about 800 cPs to about 15,000 cPs, 800 cPs to about 12,000 cPs, about 1000 cPs to about 15,000 cPs, from about 1000 cPs to about 12,000 cPs, from about 1500 cPs to about 15,000 cPs, from about 1500 cPs to about 12,000 cPs, from about 2000 cPs to about 15,000 cPs, or from approximately 2000 cPs to approximately 12,000 cPs, when measured at 25°C using a Brookfield DV-II+ Pro viscometer, RV pin at 10 rpm.

The compositions may have a pH less than or equal to 9, such as about 3 to about 8, about 4 to about 7, or about 5 to about 6.5.

In various embodiments, the compositions according to the present disclosure are stable, that is, no phase shift or significant change in pH or viscosity is observed when stored at a temperature ranging from approximately 4°C to about 45°C, preferably about 10°C to about 37°C, more preferably about 20°C to about 30°C, for at least about 8 weeks.

In at least some embodiments, the compositions according to the disclosure may be gentle, exhibit good foaming properties, good detangling and combing properties, good antistatic properties, and/or good stability. The compositions may impart one or more properties such as softness, conditioning, excellent detangling, anti-frizz, ease of shaping and/or combing, antistatic, clean and/or smooth appearance, without weight.

II. Processes

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, the methods of cleaning 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 a 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 length of time, and optionally rinsing the composition from the keratinous material. The composition may optionally be foamed before application to keratinous materials, for example in the hands, or may be foamed while on the keratinous materials.

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 the present disclosure are particularly useful for cleansing and conditioning hair. Additionally, the compositions provide a variety of desirable cosmetic and styling benefits to hair, e.g., softness without weighing, detangling, and anti-frizz. As such, the compositions are useful in methods of cleaning hair, methods of conditioning hair, and methods of providing softness, detangling, and/or frizz control to hair. Accordingly, the present disclosure encompasses methods of treating hair with the compositions of the present disclosure.

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 from letting the hair air dry or drying the hair with a hair dryer which blows air through the hair and speeds drying. Usually, the composition is simply left on the hair for a sufficient 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. which may exist on the hair so that when rinsing, 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 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 about 10 seconds to about 3 minutes. The composition is then rinsed from the hair, and the hair is allowed to dry.

As is common when using shampoos and/or conditioning compositions, hair may be wetted or rinsed with water prior to application of a composition described herein. Already having water in the hair can be helpful in creating lather when applying the compositions because the water interacts with the surfactants.

Having described in detail the numerous embodiments of the present invention, it is evident that modifications and variations are possible without departing from the scope of the disclosure set forth in the appended claims.
