Description

929402-00-WG-01-PCPERSONAL CARE COMPOSITIONSCROSS-REFERENCE TO RELATED APPLICATION

[0001] This application claims the benefit of priority from U.S. Provisional Patent Application No. 63 / 723,461, filed 21 November 2024, the contents of which are hereby incorporated herein by reference in their entirety.BACKGROUND

[0002] Many personal care compositions that are available in the market today have multiple ingredients, which serves to drive high production cost and processing time. Furthermore, multiple surfactants are utilized in personal care and home care products to impart foaming properties, and the use of certain surfactants may raise concerns about environmental influences and dermatological issues.

[0003] Liquid cleansing compositions, such as aqueous foaming compositions like hand soaps, body washes, and shower gels, should desirably have acceptable levels of foam production for consumer satisfaction. Foam production is a key attribute for consumers when choosing products. To achieve a desirable foam production, manufacturers incorporate sufficient quantities of active ingredients, such as surfactants, into the compositions. Liquid cleansing compositions require minimal levels of surfactant to provide good cleaning and dispensing properties and good foaming of the liquid cleansing composition during use. Also, it is desired to provide a sufficient amount of foam that is stable for a desired amount of time during use and has a desirable foam texture, such as sufficient creaminess. Multiple surfactants and surfactant amounts, however, may serve to increase cost and manufacturing complexities of personal care compositions.

[0004] Accordingly, there is need for formula simplification of personal care compositions such as hand soaps, body washes, and shower gels to eliminate or reduce ingredients, including ingredients of concern, without comprising the product’s efficacy and end benefits to the user.BRIEF SUMMARY

[0015] Further areas of applicability of the present disclosure will become apparent from the detailed description provided hereinafter. It should be understood that the detailed description and specific examples, while indicating embodiments of the disclosure, are intended for purposes of illustration only and are not intended to limit the scope of the disclosure.DETAILED DESCRIPTION

[0016] The following description of the various embodiment(s) is merely exemplary in nature and is in no way intended to limit the disclosure, its application, or uses.

[0017] As used throughout, ranges are used as shorthand for describing each and every value that is within the range. Any value within the range can be selected as the terminus of the range. In addition, all references cited herein are hereby incorporated by reference in their entireties. In the event of a conflict in a definition in the present disclosure and that of a cited reference, the present disclosure controls.

[0018] Unless otherwise specified, all percentages and amounts expressed herein and elsewhere in the specification should be understood to refer to percentages by weight. The amounts given arebased on the active weight of the material. According to the present application, the term “about” means + / - 10% or less of the reference value. According to the present application, the term “substantially free” indicates less than about 0.1 wt% based on the total of the referenced value, such as less than about 0.01 wt%, less than about 0.001 wt%. less than about 0.0001 wt%. or an amount that is not detectable.

[0019] As used herein, the use of a compound comprising several isomers or stereoisomers includes all the isomeric forms of that compound. When referring to chemical structures and names, the symbols “C”, “H”, and “O” mean carbon, hydrogen, and oxygen, respectively. The symbols “=” and “= ’ mean single bond, double bond, and triple bond, respectively. For readability purposes, the chemical functional groups are in their adjective form; for each of the adjectives, the word “group” is assumed. For example, the adjective “alkyl” without a noun thereafter should be read as “an alkyl group.”

[0020] Any member in a list of species that are used to exemplify or define a genus may be mutually different from, or overlapping with, or a subset of, or equivalent to, or nearly the same as, or identical to, any other member of the list of species. Further, unless explicitly stated, such as when reciting a Markush group, the list of species that define or exemplify the genus is open, and it is given that other species may exist that define or exemplify the genus just as well as, or better than, any other species listed.

[0021] All components and elements positively set forth in this disclosure can be negatively excluded from the claims. In other words, the personal care compositions of the instant disclosure can be free or essentially free of all components and elements positively recited throughout the instant disclosure. In some instances, the personal care compositions of the present disclosure may be substantially free of non-incidental amounts of the ingredient(s) or compound(s) described herein. A non-incidental amount of an ingredient or compound is the amount of that ingredient or compound that is added into the personal care composition by itself. For example, a personal care composition may be substantially free of a non-incidental amount of an ingredient or compound, although such ingredient(s) or compound(s) may be present as part of a raw material that is included as a blend of two or more compounds.

[0022] Some of the various categories of components identified may overlap. In such cases where overlap may exist and the personal care composition includes both components (or the composition includes more than two components that overlap), an overlapping compound does not representmore than one component. For example, caprylyl glycol may be characterized as both a humectant and a preservative. If a particular personal care composition includes both a humectant and a preservative, caprylyl glycol will serve only as either a humectant or a preservative — not both.

[0023] As used herein, the terms “composition” and “formulation” can be used interchangeably within the specification.

[0024] Aspects of the disclosure are directed to a personal care composition. The personal care composition may comprise a surfactant blend. In certain embodiments, the personal care composition may comprises a surfactant blend comprising at least two surfactants, such as at least three surfactants, and in certain embodiments, the personal care composition may comprise a surfactant blend consisting of two surfactants or consisting of three surfactants. In certain embodiments, the personal care composition comprises a surfactant blend comprising or consisting of at least one sensate agent, and in certain embodiments, the surfactant blend comprises SLES 1- EO, cocamidopropyl betaine, and an alkyl polyglucoside.

[0025] In some embodiments, the personal care composition may be a cosmetically acceptable composition that can be used for cleansing a skin surface, especially a human skin surface, and which contain ingredients that are safe for the environment, i.e. ingredients that in sewage disposal plants may be decomposed into substantially harmless substances, and which have a protective effect on the skin (e.g., against irritation and drying).

[0026] In some embodiments, the personal care composition may also provide an emollient effect, as well as having excellent cosmetic and physical stability. In some embodiments, the personal care compositions disclosed herein impart conditioning, smoothing, and / or emollient properties to the skin and, thus reduce the tendency to develop dry, irritated, or otherwise traumatized skin.

[0027] As used herein, the term “skin surface” relates to the outermost surface of the body and embraces intact skin as well as injured skin surfaces, mucosa and mucous membranes. The term “skin surface” is used in a broad sense, embracing both the epidermal layer of the skin and also the dermal layer of the skin. The epidermal layer of the skin is the outer (epithelial) layer, and the deeper connective tissue layer of the skin is called the dermis. The skin may have a thick or a thin epidermis and is therefore often classified as thick or thin skin. In the present context, the term “skin” embraces thick skin as well as thin skin.

[0028] The term “soap” as used herein is given a broad meaning and is intended to encompass agents to clean the hands, hair, and / or the body, including cosmetic or detergent substances as929402-00-WG-01-PC described in 21 C.F.R. 701.20, particularly products generally referred to as liquid hand soaps and body washes.Surfactant blend

[0029] In certain embodiments of the disclosure, the personal care composition comprises a surfactant blend that delivers a notable skin feel and can help to promote end user benefits, such as desirable foam properties, moisturization, fragrance, hydration of the skin, etc., while simultaneously reducing formulation costs and / or simplifying the formulation process.

[0030] In certain embodiments, disclosed herein is a personal care composition comprising a surfactant blend, wherein a first surfactant is an anionic surfactant. As used herein, “anionic surfactant” means those surface-active or detergent compounds that contain an organic hydrophobic group containing generally 8 to 26 carbon atoms or generally 10 to 18 carbon atoms in their molecular structure and at least one water-solubilizing group selected from sulfonates, sulfates, and carboxylates so as to form a water-soluble detergent. Usually, the hydrophobic group will comprise a C8-C22 alkyl or an acyl group. Such surfactants are employed in the form of water- soluble salts, and the salt-forming cation may be selected from sodium, potassium, ammonium, magnesium and mono-, di- or tri-C2-C3 alkanolammonium, with the sodium, magnesium and ammonium cations again being the usual ones chosen. Some examples of suitable anionic surfactants include, but are not limited to, the sodium, potassium, ammonium, and ethanolammonium salts of linear -Cis alkyl ether sulfates, ether sulfates, and salts thereof. Suitable anionic ether sulfates have the formula R(OC2H4)nOSO3M, wherein n is 1 to 12, or 1 to 5, and R is an alkyl, alkylaryl, acyl, or alkenyl group having 8 to 18 carbon atoms, for example, an alkyl group of C12-C14 or C12-C16, and M is a solubilizing cation selected from sodium, potassium, ammonium, magnesium and mono-, di- and triethanol ammonium ions. Exemplary alkyl ether sulfates contain 12 to 15 carbon atoms in the alkyl groups thereof, e.g., sodium laureth (2EO) sulfate or sodium laureth (1EO) sulfate. In certain embodiments, a preferred exemplary anionic surfactant that may be used in the personal care compositions of the present disclosure include SLES 1EO.

[0031] SLES is an anionic surfactant that is widely used in cleaning products and personal care compositions as a primary surfactant. In addition to an excellent ability to clean a surface (e.g., skin), SLES also has excellent emulsification and foamability properties. SLES is prepared by ethoxylation of dodecyl alcohol produced from palm kernel oil or coconut oil, followed by the929402-00-WG-01-PC sulfation of the resulting ethoxylate and neutralization to the sodium salt. 1,4-dioxane may be formed as a by-product during the ethoxylation step.

[0032] The chemical formula of SLES is CH3(CH2)n(OCH2CH2)nOSO3Na. SLES is heterogeneous in the number of ethoxyl groups. The average degree of ethoxylation can be specified in the name. For example, SLES 1EO refers to SLES having an average degree of ethoxylation of 1.

[0033] SLES raw materials contain trace amounts of 1,4-dioxane. which is a chemical formed as a by-product during the ethoxylation step. The higher the number of ethoxyl groups is, the higher level of 1,4-dioxane SLES raw materials contain. For example, SLES 2EO (SLES having an average degree of ethoxylation of 2) contains up to about 50 ppm 1,4-dioxane. If 7-18% of SLES 2EO is contained in a composition, the composition will contain more than 1 ppm 1,4-dioxane. 1,4-dioxane is a likely carcinogen. 1,4-dioxane is very stable and does not degrade naturally. Furthermore, it is not possible to eliminate 1,4-dioxane in the processes of treating water. It has been recognized that the usage of compositions containing SLES has impact on ground-water contamination. The United States Food and Drug Administration (FDA) recommends that the level of 1,4-dioxane in products be monitored and encourages manufacturers to remove 1,4-dioxane. New York is banning the sale of household cleaning and personal care products containing more than 2 ppm 1,4-dioxane at the end of 2022 and more than 1 ppm at the end of 2023.

[0034] One approach to eliminate or reduce 1,4-dioxane in certain compositions, such as home care compositions, is to use sodium lauryl sulfate (without ethoxylation) instead of SLES. However, the stability of such compositions containing sodium lauryl sulfate (SLS) at low temperature may be poor and a user's skin may get irritated after contact with the composition. As noted above, the lower the degree of ethoxylation of SLES, the lower the concentration of 1,4- dioxane will be. Accordingly, in certain embodiments, the sodium lauryl ether sulfate used in the personal care compositions disclosed herein may have an average ethoxylation of less than 2. In certain embodiments, the sodium lauryl ether sulfate used in the personal care compositions disclosed herein may have an average ethoxylation of about 1 to about 5 mole per mole of lauryl ether sulfate group. In some instances, the average ethoxylation of the sodium lauryl ether sulfate is about 1 to about 4, about 1 to about 3, about 1 to about 2, or about 1 mole per mole of lauryl ether sulfate group. In certain embodiments, the sodium lauryl ether sulfate has an average ethoxylation of 1 about mole per mole of lauryl ether sulfate group or less.

[0035] Other non-limiting examples of suitable anionic surfactants that may be used are alkyl benzene sulfonates, alkyl ether sulfates, olefin sulfonates, alkyl sulfonates, secondary alkyl sulfonates, fatty acid ester sulfonates, dialkyl sulphosuccinates, alkyl ortho xylene sulphonates, and alkali metal soaps of a fatty acid, such as those containing 12 to 18 carbon atoms. Typical such acids are oleic acid, ricinoleic acid, and fatty acids derived from castor oil, rapeseed oil, groundnut oil, coconut oil, palm kernel oil. or mixtures thereof. The sodium or potassium soaps of these acids can also be used.

[0036] The anionic surfactants are preferably used as sodium salts, but may also be present as other alkali or alkaline earth metal salts, for example magnesium salts, and in the form of ammonium or mono-, di-, tri- or tetraalkylammonium salts, in the case of the sulfonates also in the form their corresponding acid, e.g. dodecylbenzenesulfonic.

[0081] Multiple two- surfactant formulations were prepared as shown below in Table 1. Notably, none of the two-surfactant formulations contained CMEA, polyquaternium 7, or EDTA.

[0082] Table 1 - Two- Surfactant Formulations Comprising SensatesExample 2 - Stability Evaluations

[0083] The compositions prepared in Example 1 were evaluated for stability. For viscosity, measurements were taken at 20 PRM at 25 °C, 24 hours after removal from oven chambers. Table 2 below shows the results of physical stability testing.929402-00-WG-01-PC

[0084] Table 2 - Summary of Physical Stability Parameters

[0085] All four prototypes (Comp. 1 - Comp. 4) showed good viscosity measurements, as expected and typical for body wash products. Although Comp. 3 (sorbitol) gave a high reading at 13,680 cP, Comp. 2 (TEC / Sorbitol) was observed with the lowest viscosity at 8,860 cP. While not wishing to be bound by theory, it is believed that this is due to the impact of the TEC, which lowers the viscosity in formulations. The analytically tested micro robustness results showed all formulations passed and exhibited good robustness against bacteria growth, a key criteria for product stability. The pH as well as the clarity of each formulation was also considered within an acceptable range.

[0086] Compositions 2 and 4 were further aged for 13 weeks at 40 °C and the pH and viscosity of the aged samples were measured. Composition 2 had a pH of 4.19 and a viscosity of 13,080 cPs, while Composition 4 had a pH of 4.2 and a viscosity of 11,160 cPs.Example 3 - Performance Evaluations

[0087] A fifth test composition (Comp. 5) was prepared as described above but containing 0.5% Aurist™ AGC (IFF, Inc.) as the added sensate. Aurist™ AGC is a combination of alpha-glucan hydroxypropyltrimonium chloride and propylene glycol. It is made by a bio-fermentation process from sucrose and is known to be a conditioning agent for hair and skin. For skin in body wash applications, it reduces roughness and improves rinsability.

[0088] The formulations were evaluated using Dynamic Foam Analysis (DFA) for foam volume, and an initial bubble count was performed. Additionally, the sensorial / skin feel was evaluated via an assessment on a scale of 1 (least) to 5 (highest) among 5-6 people to test how the formulations performed during use on their hand and arm. Samples for DFA analysis were prepared by adding 5 g of each of the control or the Composition 1-4 with 95 g of tap water. Each sample was measured in duplicate or triplicate, and the results were averaged. 50 g of the DFA sample was used for each measurement.929402-00-WG-01-PC

[0089] For the sensorial attributes questionnaire, users were asked to describe and rate on a scale of 1 to 5 (with 1 being the lowest and 5 the highest) how the overall foam feels, e.g., its sensorial properties such as cushiony, slippery, smooth, and whether the user could feel the sensate material from the product on their hands, i.e., was is notable. Additionally, users were asked to rate on a scale of 1 to 5 (with 1 being the lowest and 5 the highest) the amount of foam, the foam creaminess, the immediate moisture feel (immediately after washing hands), and the moisture feel 15 minutes after washing hands. The results are shown below in Table 3.

[0090] Table 3 - Summary of Performance Evaluations

[0091] As indicated by the DFA results, the Maximum Foam Volume overall for each of Compositions 1-5 performed better than the control. The initial bubble count, a gauge on how many bubbles are generated when making foam, was observed to be parity to the control for Compositions 1, 2, 4, and 5. The results of sensorial questionnaire show that Comp. 2 and Comp.4 received the strongest sensorial ratings, and all of Compositions 1-5 had improved sensorial properties as compared to the control.
