Liquid cleansing compositions, such as aqueous foaming compositions like hand soaps, facial soaps or cleansers, body washes, and shower gels, should desirably have acceptable levels of foam production for consumer satisfaction. Foam production, for example, is a key attribute for consumers when choosing products. To achieve a desirable foam production, manufacturers incorporate sufficient quantities of foaming agents, such as surfactants, into the compositions.
However, in recent years, consumer demand for more natural products has increased—e.g., interest in the origin of raw materials and products with ingredients with a high degree of naturality. It is a challenge to produce formulations that have the physical characteristics that consumers expect, including desirable amounts of foam production and sufficient viscosity, while simultaneously achieving a high degree of naturality. Moreover, liquid consumer products normally contain different species of surfactants. Consequently, manufacturers are shifting to the use of natural/sustainable surfactant substitutes. One challenge with surfactant substitutes, however, is maintaining an acceptable foaming volume that is still acceptable for consumers.

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.
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 represent more than one component. For example, certain compounds may be characterized as both a polysaccharide and a thickener. If a particular personal care composition includes and/or recites both a polysaccharide and a thickener, the compound that may be characterized as both a polysaccharide and a thickener will serve only as either the polysaccharide or the thickener—not both.
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.”

Suitable components, such as those listed below, may be included or excluded from the formulations for the personal care compositions depending on the specific combination of other ingredients, the form of the personal care composition, and/or the use of the composition (e.g., cleanser (such as, a facial cleanser), a face wash, a body wash, a serum, a lotion, a cream, a spray, etc.). For example, the personal care composition may include a hydrophilic phase and a hydrophobic phase when the personal care composition is in the form of an emulsion or a two-phase composition. In some embodiments, the personal care composition is in the form of a skin care composition, a cleansing compositions, and/or a facial cleansing composition. Preferably, the personal care composition is self-foaming. The personal care composition may be referred to a as self-foaming compositions herein when the personal care composition is self-foaming. The personal care composition should not be interpreted as not-self foaming when the personal care composition is simply referred to as a personal care composition.
The personal care compositions are typically self-foaming compositions. The personal care compositions may foam upon being dispersed from the container containing such personal care composition and/or upon application to a keratin substrate, such as skin. For example, the personal care composition may foam and/or start to foam within 1 second, 2 seconds, 4 seconds, 6 seconds, 10 seconds, 15 seconds, 30 seconds, or 60 seconds from being dispersed from the container. Preferably, the personal care composition foam is capable of foaming without the use of mechanical foaming apparatuses, such as a pump with a foaming chamber. Additionally or alternatively, the personal care composition may foam within 1 second, 2 seconds, 4 seconds, 6 seconds, 10 seconds, 15 seconds, 30 seconds, or 60 seconds from being applied to a keratin substrate, such as skin.
The personal care composition may be formulated to produce a max foam height of about 1 mm or more, about 1.1 mm or more, about 1.2 mm or more, about 1.4 mm or more, about 1.6 mm or more, about 1.7 mm or more, about 1.8 mm or more, about 1.9 mm or more, or about 2 mm or more after being applied to a substrate. In some embodiments, the personal care composition is formulated to produce a max foam height of about 1 mm or more, about 1.1 mm or more, about 1.2 mm or more, about 1.4 mm or more, about 1.6 mm or more, about 1.7 mm or more, about 1.8 mm or more, about 1.9 mm or more, or about 2 mm or more after being applied to a substrate (e.g. skin) having a temperature of about 37° C.
The personal care composition may be further rubbed on a keratin substrate to, in some instances, increase foaming of the personal care composition. For example, the personal care composition may be formulated such that when applied to a heated substrate (e.g., skin) at a temperature of, e.g., about 37° C., and rubbed in a circular motion about 16 times at a rate of 96 rubs per minute, the personal care composition produces a first foam height of about 1 mm or more at or within 30 seconds after being rubbed and produces a second foam height that is at least 75% greater than the first foam height at or within 80 seconds after said being rubbed. In some embodiments, the personal care composition is formulated to produce a first foam height at or within 30 seconds after being applied to a heated substrate (e.g., skin) at a temperature of, e.g., about 37° C., and rubbed in a circular motion about 16 times at a rate of 96 rubs per minute of about 1 mm or more, about 1.1 mm or more, about 1.2 mm or more, about 1.4 mm or more, about 1.6 mm or more, about 1.7 mm or more, about 1.8 mm or more, about 1.9 mm or more, or about 2 mm or more. Additionally, the personal care composition may be formulated to produce a second foam height at or within 80 seconds after being applied to a heated substrate (e.g., skin) at a temperature of, e.g., about 37° C., and rubbed in a circular motion about 16 times at a rate of 96 rubs per minute, wherein the second foam height greater than the first foam height by at least 45%, at least 55%, at least 65%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, at least 100%, at least 105%, or at least 110%.
It was surprisingly discovered that the above foam heights may achieved by personal care compositions after undergoing accelerated aging by kept in a controlled environment at a temperature of 40° C. for 4 weeks. Additionally or alternatively, the personal care compositions may be specifically adapted to achieve an average maximum height according to DFA lather performance after being after undergoing accelerated aging by kept in a controlled environment at a temperature of 40° C. for 4 weeks of about 70 mL or more, about 74 mL or more, about 77 mL or more, about 79 mL or more, about 82 mL or more, or about 85 mL or more.
The personal care composition typically comprises one or more hydrocarbon(s) comprising from 4 to 6 carbons (C4-6 hydrocarbons). The total amount of C4-6 hydrocarbon(s) may be from about 0.5 to about 10 wt. %, based on the total weight of the personal care composition.

The C4-6 hydrocarbon(s) may comprise hydrocarbons having 4 carbons, 5 carbons, 6 carbons, or any range or combination thereof. In at least one preferred embodiment, the C4-6 hydrocarbon(s) comprises a hydrocarbon having 5 carbons (C5 hydrocarbon(s)). For example, the C5 hydrocarbon(s) may comprise pentane, isopentane, or a combination thereof. In certain embodiments, the C4-6 hydrocarbon(s) consists of C5 hydrocarbon(s). The self-foaming personal care composition may comprise isopentane in an amount up to about 1.5 wt. %, up to about 1.25 wt. %, up to about 1 wt. %; from about 0.1 to about 1.5 wt. %, about 0.1 to about 1.25 wt. %, about 0.1 to about 1 wt. %; from about 0.5 to about 1.5 wt. %, about 0.5 to about 1.25 wt. %, about 0.5 to about 1 wt. %, or any range or subrange thereof, based on the total weight of the self-foaming personal care composition.
The self-foaming personal care composition may, preferably, comprise isopentane and pentane in a weight ratio of isopentane to pentane of about 4:1 to about 1:3, about 3:1 to about 1:3, about 2:1 to about 1:3, about 1:1 to about 1:3; from about 4:1 to about 1:2, about 3:1 to about 1:2, about 2:1 to about 1:2, about 1:1 to about 1:2; from about 4:1 to about 1:1, about 3:1 to about 1:1, about 2:1 to about 1:1, or any range or subrange thereof.
The inventors discovered that self-foaming personal care compositions comprising a C4-6 hydrocarbon(s) can unexpectedly be improved by incorporating certain combinations of fatty ester(s), fatty acid(s), silicone(s), triglycerides (e.g., medium chain triglycerides), and vitamin E in particular amounts and weight ratios thereof. One such benefit achieved by the personal care compositions disclosed herein is a reduced foaming during the production process of such personal care composition. It was unexpectedly discovered, however, that certain combinations of fatty ester(s), fatty acid(s), silicone(s), triglycerides (e.g., medium chain triglycerides), and vitamin E in particular amounts and weight ratios can achieve both a reduced amount of foaming during the production process of such personal care composition while maintaining desirable levels of foaming during use (e.g., lather) of the personal care composition. Further, it was discovered that certain surfactant system in conjunction with the combinations of fatty ester(s), fatty acid(s), silicone(s), triglycerides, and vitamin E can enhance the self-foaming characteristic of the personal care composition, especially after aging.

A non-limiting, exemplary self-foaming personal care composition (Example Composition A) was prepared in accordance with an aspect of the invention. The formulation for Example Composition A is provided in Table 1.
Compositions containing pentane, one or more fatty acid, and one or more fatty ester were evaluated to determine their respective boiling points. The compositions were prepared in accordance with the formulas presented in Table 2 along with the boiling points of the respective compositions.
It is believed that an increase in the boiling point may contribute to an increased processing stability as well as increased stability during storage even in unpressurized cosmetic packaging.
Three non-limiting exemplary personal care compositions (Example Compositions B-D) and two comparative personal care compositions (Comparative Compositions 1 and 2) were prepared in accordance with aspects of the invention. The formulation for Example Compositions B-D and Comparative Compositions 1 and 2 are shown in Table 3.
Example Compositions B-D and Comparative Compositions 1 and 2 were assessed to determine the amount of foam yielded from each composition after 4 hours. Specifically, samples weighing 60 grams for each of Example Compositions B-D and Comparative Compositions 1 and 2 were added to jars, followed by hand-mixing with a spatula for 50 seconds. The samples were then left uncapped and monitored for at least 4 hours to elucidate any differences in the generation of self-foam after the addition of the isopentane premixes. The amount of foam produced while the sample was in an open jar in ambient conditions was measured with a ruler (from the starting point of the liquid to the top of the self-generated foam layer) and reported in Table 4.
Eleven non-limiting, exemplary self-foaming personal care compositions (Example Compositions E-P) were prepared in accordance with aspects of the invention. A comparative composition (Comparative Composition 3) was also prepared, which did not have disiloxane, dimethicone, coconut acid, or vitamin E. The formulations for Example Compositions E-P and Comparative Composition 3 are provided in Table 5.
Example Compositions E-P and Comparative Composition 3 were evaluated during their production to assess the foam generation during their production process. Specifically, each personal care compositions was prepared by combining polyhydroxystearic acid, isononylisononanoate, ethylhexyl isononanoate, cocamidopropyl pg-dimonium chloride phosphate, phenyl propyl alcohol, caprylyl glycol, 1,3-propanediol, alpha-tocopherol, isopentane, deionized water, one of disiloxane, dimethicone, coconut acid, or tocopheryl acetate (if present) in the respective amount for such personal care composition to form a first mixture. The first mixture was then homogenized for 30 seconds at 3,800 to 4,000 rpm. The first mixture was then combined with a second mixture containing the remaining ingredients of the respective personal care composition and then mixed for 10 minutes at 50 rpm with overhead stirring. Each personal care composition was then left in the uncovered beaker for 30 minutes before measuring the foam height.
A non-limiting, exemplary self-foaming personal care composition (Example Composition Q) was prepared in accordance with aspects of the invention. The formulation for Example Composition L is provided in Table 6.
Two non-limiting, example self-foaming personal care compositions (Example Compositions R and S) were prepared in accordance with an aspect of the invention. The formulations for Example Compositions R and S are provided in Table 7.

Other than the surfactant systems, contained therein, Compositions T-AC had substantially same formulations. The formulations for Compositions T-AC are shown in Table 8.
The self-foaming characteristic of Compositions T-AC was evaluated after accelerated aging of such personal care compositions. Specifically, samples of Compositions T-AC were placed in a controlled environment at a temperature of 40° C. for 4 weeks. Upon completion of the 4 weeks of accelerated aging, the samples of Compositions T-AC were evaluated to determine their rate of vertical foam growth and DFA lather performance.
To assess the rate of vertical foam growth, samples of Compositions T-AC were pumped into respective beakers. Subsequently, 1 mL of the respective personal care composition was taken from the beaker using a syringe and dispensed onto a heated substrate having a temperature of 37° C. The personal care composition was then rubbed in a circular motion 16 times at a pace of 96 rubs per minute, which is equivalent to 10 seconds. The foam growth of the personal care composition was video recorded in a photobox and analyzed using the in-house built software to assess the rate of vertical foam growth for Compositions T-AC.
To assess the DFA lather performance, samples of Compositions T-AC were diluted with water to produce a solution comprising 5 wt. % of the respective sample of Composition T-AC with the remainder being water. The DFA stirred the solution and measured the maximum foam height, which corresponds to the foam lathering of the personal care composition during use.
A summary of the rate of vertical foam growth as a function of time for Compositions T-AC is shown in
A non-limiting, exemplary self-foaming personal care composition (Example Compositions AD) were prepared in accordance with an aspect of the invention. The formulation for Example Composition AD is provided in Table 9.
