According to various aspects of the present disclosure an eyelash composition, eyebrow composition and/or mascara component composition can include an active component. The active component can include an OR2AT4 agonist or analogs thereof. Olfactory receptors are expressed by different cell types throughout the body and regulate physiological cell functions beyond olfaction. In particular, the olfactory receptor OR2AT4 has been shown to stimulate keratinocyte proliferation in the skin. It is believed that specific stimulation of OR2AT4 can prolong eyelash and/or eyebrow hair growth ex vivo by decreasing apoptosis and increasing production of the anagen-prolonging growth factor IGF-1.
Olfactory receptors (ORs) are part of an evolutionarily ancient chemosensory signaling system that long predates the development of smell sensation (olfaction). OR expression is not restricted to the nasal epithelium, but it is also present in several other human tissues. Non-olfactory roles of ORs have also been described in human cell physiology, such as in spermatozoa and enterochromaffin cells of the gut (Cheret et al. Nature Com. 2018. Vol 9).
Interestingly, several ORs are also expressed in human epidermis, including OR2AT4, whose selective activation by the synthetic sandalwood odorant (Sandalore®) promotes human epidermal keratinocyte migration and proliferation in vitro and wound re-epithelialization ex vivo.
One embodiment relates to a composition comprising at least one active that act improves eyelash and/or eyebrow appearance and/or health. The composition comprises at least one OR2AT4 agonist.
Sandal pentanol is an example of a OR2AT4 agonist for use in the present compositions and methods. Sandal pentanol is a synthetic odorant having a fragrance used as an ingredient mimicking the sandalwood scent. Sandal pentanol ia an alcohol having a chemical structure quite distinct from the ingredients of natural sandalwood oil which usually are extracted by steam distillation of wood from matured sandalwood trees. The IUPAC denomination of sandal pentanol is 3-methyl-5-(2,2,3-trimethylcyclopent-3-en-1-yl) pentan-2-ol. Sandal pentanol has been shown to have a stimulatory effect on the olfactory receptor OR2AT4, which is expressed in the epithelium of human hair follicles. Simulation of OR2AT4 by sandal pentanol in turn prolongs hair growth ex vivo by decreasing apoptosis and increasing the production of growth factor IGF-1. Sandal pentanol accordingly in believed to act as an agonist promoting the growth of mammalian hair.
Analogs or derivatives, respectively, of sandal pentanol are believed to have a similar effect on mammalian hair growth, and may be used in the present disclosure alternatively or additionally to sandal pentanol. Sandal pentanol analogs suitable as active ingredients include:
Cosmetic compositions described herein will comprise an amount of OR2AT4 agonist effective to provide a benefit to eyelashes, such as without limitation improving lash root sheath thickness and/or improving lash anchorage, and/or eyebrows (or other facial hair). For example, the cosmetic composition comprises an amount of an OR2AT4 agonist from 0.4 to about 1.25 weight %, based on the total weight of the composition. Alternatively, the cosmetic composition comprises an amount of OR2AT4 agonist from 1×10−6 weight % to 3×10−4 weight %, or about 2×10−6 weight % to about 2.5×10−4 weight %, or about 1×10−5 weight % to about 2.5×10−4 weight %, or about 2×10−5 weight % to about 2×104 weight %, based on the total weight of the composition. In some embodiments, the composition comprises at least about 1×10−5 weight %, or at least about 2×10−5, or at least about 1×10−4 weight % or an OR2AT4 agonist. In some embodiments, the composition comprises at least about 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 125, 150, 175, 200, 225, 250, 275, 300, 325, 350, 375, 400, 425, 450, 475, 500, 525, 550, 575, 600, 625, 650, 675, 700, 725, 750, 775, 800, 825, 850, 875, 900, 925, 950, 975, 1000 μM of an OR2AT4 agonist. In some embodiments, the composition contains no more than 0.03% by weight of the active agent. However treatment according to the present invention can include a very wide effective concentration range of the active agents depending the specific therapeutic goal desired. For example, the active agents (e.g., at least one OR2AT4 agonist) can have concentrations from 0.0075 to 0.03% by weight in liquid mixtures with inert ingredients.
Another embodiment relates to methods for making cosmetic compositions described herein. The OR2AT4 agonist containing compositions can be prepared in any conventional manner, such as by mixing and blending the components in any order. In some embodiments, the components are directly mixed into other cosmetic formulations for topical application to the eyes, eyebrows or eyelashes.
Embodiments provide methods for improving eyebrow and/or eyelash appearance and/or health by topically applying a composition comprising creatine and an OR2AT4 agonist to eyebrow or eyelash fibers and/or follicles for a period of time sufficient to produce one or more of the benefits described herein. Benefits may occur instantly or over the long-term. In some embodiments, a mascara comprising a composition described herein can be applied to the eyelashes. For example, the mascara is applied along the length of the eyelash fiber, optionally including touching the lash base, to contact the lash follicles. Mascara can be applied to top and/or bottom lashes using, e.g., at least about 2, at least about 3, at least about 4, at least about 5, at least about 10, at least about 15, or a least about 20 strokes of a mascara wand, wherein the wand is can be dipped into the mascara product between top and bottom lash applications. The initial coat can be allowed to dry, followed by application of a second coat or additional coats, e.g., in the same or similar manner as the first coat was applied. Mascara may also be “touched up” as needed during wear. In some embodiments, mascara application is used alone or in conjunction with application of a serum (which also can be used alone and can contain an OR2AT4 agonist).
A serum product for topical application to the eyebrows or eyelashes can be used. For example, in some embodiments, a serum comprising a composition described herein can be applied to the upper and/or lower lash line and eyebrows and lashes. The serum is typically clear or colorless. When using it in combination with mascara, the serum can be allowed to dry, e.g., before applying mascara. Application can be repeated one, two, three or more times daily, for as long as is necessary to achieve desired results, such as brow or lash nourishing and/or volumizing effects. The serum can applied at least twice daily, e.g., once in the morning, such as before applying mascara; and once in the evening, such as after removing mascara at night.
In some embodiments, the use or application of the compositions provided herein avoids application to the scalp or hair of the scalp.

Mascara formulations within which the compounds disclosed herein, including OR2AT4 agonists, may also be incorporated include those generally described below:
The particular mascara formulation and other inventive embodiments disclosed herein include an oil-in-water mascara formulation that includes a non-emulsifying wax in a concentration of 0.10 to 12.00 percent by weight; at least one viscosity modifier; and at least one non-wax grafted polymer and at least one wax grafted polymer with a combined concentration of 0.1 percent to 50 percent. While the ammonium acrylates copolymer formulation concentration is listed as 30.00% by weight and the styrene/acrylates copolymer formulation is listed as 20.00% by weight above, it is understood that other concentration ranges are suitable so long as the total concentration of these two formulations is 50% of the mascara formulation.
These ingredients form a strong, yet volumizing film, which eliminates the need for very high concentrations of waxes in the formula. Mascara formulation embodiments also include 12% or less of non-emulsifying wax in an oil phase, about 50% less than what is used conventionally in high volume washable mascara formulations. This combination of ingredients work in synergy, to form a durable and long lasting, yet high volumizing film, which is easily removed with soap and water or warm water alone. Some embodiments are easily removed with soap and water. Other embodiments are easily removed with warm water alone.
Inventive mascara embodiments directly solve a problem of making a long-lasting mascara that is also easily removable with soap and water or with warm water alone, without soap.
