[0001] This application claims priority to U.S. Provisional Patent Application No. 62/812,230, filed February 28, 2019 and U.S. Non-Provisional Application No. 16/796,865 filed on February 20, 2020

TECHNICAL FIELD

[0002] The disclosure relates to natural, plant-based cosmetic compositions, such as shampoos, body cleansers, and face cleansers, for cosmetically treating, shampooing and/or cleansing keratinous materials, and to methods of cleansing keratinous materials.

BACKGROUND

[0003] Consumers desire natural compositions for cleansing keratinous materials, including hair and skin. However, such compositions can be expensive to produce as their materials must be sourced from natural sources such as plants, as opposed to being high-volume, industrially-produced chemicals. Moreover, it is difficult to achieve an acceptable balance of desirable cleansing composition performance properties, especially when manufacturers are limited to using naturally-sourced products. For example, consumers may seek cleansing compositions that foam and cleanse well, have a certain“thickness” (viscosity), are mild to the skin and hair, and rinse away from the body with ease. However, the addition of a particular component to a cleansing composition will often enhance one desired property to the detriment of another desired property. [0004] It is particularly difficult to replace the high-volume, low-cost industrially-produced surfactants widely used in aqueous based personal care products, with naturally-derived surfactants. From the consumer's perspective, the amount and stability of the foam directly relates to the perceived cleaning efficiency of the composition. Generally speaking, the larger the volume of foam produced and the more stable the foam, the more efficient is the perceived cleaning action of the composition. This presents a potential problem in low-surfactant formulations, as foam volume tends to decrease with decreasing surfactant concentration.

[0005] Non-natural sulfate-based surfactants (such as, for example, sodium lauryl sulfate and sodium lauryl ether sulfate) may be chosen because of their effectiveness in cleansing, foam production, and stability. Personal care cleansers containing sulfate-based surfactants are also generally easy to thicken with typical thickeners. Nonetheless, these particular surfactants can be harsh and irritating to skin. For instance, over-use of sulfate-based surfactants can cause needless drying to the face and scalp, and contribute to color fading and drying of hair.

[0006] Replacing these surfactants with natural surfactants has been difficult. The industrial process of ethoxylation makes surfactants more water soluble, and thus improves surfactant cleaning, emulsifying, and wetting properties. Yet consumers desire natural cleansing products which are equivalent in performance to the formulations that they use. Cleansing compositions are expected to adequately cleanse the hair and/or skin. Moreover, consumers desire cleansing compositions that are made up primarily of natural materials, including natural thickeners, as opposed to having just one natural ingredient. This complicates the ability to produce natural cleansing products with good cosmetic properties. [0007] Eliminating sulfate surfactants from cleansing compositions has been particularly challenging because non-sulfate based compositions typically have poor foaming properties, are difficult to thicken, and may not provide the desired degree of clarity or transparency (if clear compositions are desired). Also, the cleansing ability of non-sulfate-based compositions may be sub-optimal.

[0008] In addition to having excellent cosmetic qualities, these natural compositions also require a certain viscosity or rheology to be recognized as a specific product - e.g., a shampoo, a body cleanser, or a face cleanser - and to be convenient for dispensing and using and thus desirable to consumers. It is known practice to use compositions that contain conventional thickeners, either natural or synthetic, in order to give such compositions a certain viscosity or rheology.

Nonetheless, conventional thickeners may lack sustainable sourcing and not comply with“green” manufacturing processes, which in turn can lead to harmful effects on the environment.

[0009] Due to the concerns regarding conventional thickeners, industrial surfactants and/or sulfate-containing surfactants, manufacturers seek to formulate compositions for applying to and/or cleansing keratinous materials using ingredients and combinations of ingredients that can minimize or prevent the above-described disadvantages. However, the choice of ingredients or combinations of ingredients poses difficulties insofar as they cannot be detrimental to other cosmetic attributes such as cosmetic feel, volume, bounce, hair individualization, and suppleness;

viscosity or rheology properties of cleansing compositions; stability of the

compositions, or result in more disadvantages such as increased irritation of the scalp and damage to the hair. It is therefore desirable to provide the consumer with compositions that can care for and/or cleanse keratinous materials, wherein the compositions have the desired viscosity or rheology and cosmetic attributes, while being comprised of raw materials that are of sustainable sourcing and produced by green manufacturing processes. It is also desirable to provide consumers with compositions that are non-sulfate-based.

SUMMARY

[0010] It has now been surprisingly and unexpectedly discovered that combining an anionic surfactant system comprising at least one non-ethoxylated anionic surfactant with a nonionic surfactant system, at least one amphoteric surfactant, and at least one thickening agent chosen from plant-based cationic polymers results in compositions with desired cosmetic qualities and level of structuring and viscosity (or rheology), while avoiding the use of synthetic anionic surfactants and conventional thickeners. For example, the compositions may, in various embodiments, achieve desired properties while avoid using secondary gums (e.g. non-plant-based cationic polymers such as non-guar gums), silicones, or synthetic polymers.

[0011] In various embodiments, the nonionic surfactant system comprises one or more alkylpolyglucosides and/or one or more monounsaturated glyceryl esters. In various embodiments, the nonionic surfactant system may be present in the composition in an amount ranging from about 0.1 % to about 12%, by weight of the composition. In various embodiments, the alkylpolyglucosides may be present in an amount ranging from about 0.1 % to about 10%, by weight of the composition. In various embodiments, the monounsaturated glyceryl esters may be present in an amount ranging from about 0.2% to about 2%, by weight of the composition. [0012] In various exemplary embodiments, the one or more alkylpolyglucosides may be present in an amount ranging from about 3.0% to 7.5%, by weight of the composition; the one or more monounsaturated glyceryl esters may be present in an amount ranging from about 0.2% to 2.0%, by weight of the composition; and/or the weight ratio of alkyl polyglycosides to monounsaturated glyceryl esters may range from about 3:1 to about 15:1 . The plant-derived natural anionic surfactant may achieve improved cleansing and foaming, and natural emollients and environmentally friendly cationic conditioning agents may achieve viscosity, suspension, and cosmeticity. The compositions may be high foaming without having to increase the amount of anionic surfactant, which can be damaging. The compositions also provide adequate foaming if formulated with non-sulfate based surfactants. Additionally, the compositions allow for the suspension of pearlizing agent without a non-natural thickener. The compositions optionally contain coco-based materials, which are desirable to consumers. Finally, the compositions are primarily made up of natural ingredients, which is a highly sought after attribute for environmentally-conscious consumers.

[0013] The disclosed embodiments provide compositions for applying to and/or cleansing keratinous materials. The disclosure relates, in various

embodiments, to a cleansing composition comprising: a) an anionic surfactant system comprising at least one non-ethoxylated anionic surfactant; b) a nonionic surfactant system comprising one or more alkylpolyglucosides and one or more monounsaturated glyceryl esters; c) at least one amphoteric surfactant; and d) at least one thickening agent chosen from plant-based cationic polymers; wherein the one or more alkylpolyglucosides are present in an amount ranging from about 3.0% to 7.5%, by weight of the composition; wherein the one or more monounsaturated glyceryl esters are present in an amount ranging from about 0.2% to 2.0%, by weight of the composition; wherein the weight ratio of alkyl polyglycosides to

monounsaturated glyceryl esters ranges from about 3:1 to about 15:1 .
