FIELD OF THE INVENTION
[002] The present invention relates to compositions, methods and kits for vulvovaginal applications and other conditions in an individual. CONTEXT
[003] Various compositions are needed to provide lubrication and / or to protect the skin and other tissues from damage and / or infection. Such compositions are useful alone or with one or more active and / or bioactive agents, wherein the composition serves as a drug delivery vehicle (e.g., as a transdermal drug delivery vehicle).
[004] Furthermore, vulvovaginal health continues to be a neglected medical need, as most markets in this area are largely undifferentiated, especially with regard to non-prescription or over-the-counter products. For this reason, gynecological patients in all demographics, from pre-menopause to post-menopause, who suffer from one or more vulvovaginal conditions, are often treated with prescription products or regimens, which typically have characteristics of products Petition 870260042611, dated 06 / 05 / 2026, page 5 / 250 2 / 109 to undesirable, including, (1) insufficient duration of effectiveness of a single application, (2) inadequate restoration of physiological stasis, (3) undesirable side effects and (4) unsustainable health risks.
[005] Thus, there remains a need for a variety of compositions that provide lubrication, protect the skin and other tissues, and / or facilitate the delivery of medications. In particular, there is a need for compositions and formulations capable of providing relief from vulvovaginal symptoms, treating the underlying pathophysiology or infection of the vulvovaginal anatomy, or prophylactically protecting the vulvovaginal anatomy with respect to a range of vulvovaginal health conditions.

Petition 870260042611, dated 06 / 05 / 2026, p. 13 / 250 10 / 109 by a person skilled in the art to which this disclosure pertains. The following references provide a version with a general definition of many of the terms used in this disclosure: The Cambridge Dictionary of Science and Technology (Walker ed., 1988); The Glossary of Genetics, 5th ed., R. Rieger et al. (eds.), Springer Verlag (1991); and Hale & Marham, The Harper Collins Dictionary of Biology (1991). As used herein, the following terms have the meanings assigned to them below, unless otherwise specified.
[0032] Unless specifically stated or obvious from the context, as used here, the term or is understood to be inclusive. Unless specifically stated or obvious from the context, as used here, the terms a, an, or are understood to be singular or plural.
[0033] The term approximately, when used in reference to numerical ranges, cutoffs, or specific values, is used to indicate that the recited values may vary up to 25% of the listed value. As many of the numerical values used herein are experimentally determined, it should be understood by those skilled in the art that such determinations may vary, and often do vary, between different experiments. The values used herein should not be considered unduly limiting because of this inherent variation. The term approximately is used to encompass variations of ± 25% or less, variations of ± 20% or less, variations of 10% or less, variations of ± 5% or less, variations of ± 1% or less, variations of ± 0.5% or less, or variations of ± 0.1% or less of the specified value. "Approximately" can be understood as within 10%, 9%, 8%, 7%, 6%, 5%, 4%, 3%, 2%, 1%, 0.5%, 0.1%, 0.05%, or 0.01% of the declared value.Unless clear from the context, all numerical values given here are modified by the term approximately.
[0034] As used herein, administer to the said individual and Petition 870260042611, dated 06 / 05 / 2026, page 14 / 250 11 / 109 similar terms indicate a procedure by which the described vulvovaginal compositions are introduced, instilled, implanted, applied within or applied to an individual, such that cells, tissues, mucosa or target segments of the individual's body are contacted with the composition.
[0035] The term administer, as used herein, refers to any mode of transfer, delivery, introduction or transport of an agent, for example, to an individual in need of treatment for a disease or condition. Such modes include, but are not limited to, oral, topical, intravenous, vaginal, mucous membrane, intraperitoneal, intramuscular, intradermal, intranasal and subcutaneous administration.
[0036] The ranges provided here are understood to be abbreviations for all values within the range. For example, a range from 1 to 50 is understood to include any number, combination of numbers, or subrange of the group consisting of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, or 50, as well as all decimal values intervening between the aforementioned integers, such as... For example, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, and 1.9. With regard to sub-ranges, nested sub-ranges that extend from both endpoints of the range are specifically contemplated. For example, a nested sub-range of an exemplary range from 1 to 50 might include 1 to 10, 1 to 20, 1 to 30, and 1 to 40 in one direction, or 50 to 40, 50 to 30, 50 to 20, and 50 to 10 in the other direction.
[0037] As used herein, the term analogue refers to a chemical compound that is structurally similar to another, but differs slightly in composition (such as in the substitution of an atom for an atom of a different element or in the presence of a particular functional group, or in the substitution of a functional group for an atom of a different element). Petition 870260042611, dated 06 / 05 / 2026, p. 15 / 250 12 / 109 another functional group). Thus, an analogue is a compound that is similar or comparable in function and appearance, but not in structure or origin to the reference compound. As used herein, the term derivative refers to compounds that have a common central structure and are replaced by various groups as described herein.
[0038] As used herein, the term emulsion refers to a liquefied mixture containing at least two distinguishable substances (or phases) that will not readily mix and dissolve. As used herein, an emulsion comprises a continuous phase (or matrix) that holds within it discontinuous droplets, bubbles, and / or particles of the other phase or substance. The term emulsion may thus refer to foams comprising gas bubbles suspended in a continuous liquid phase, emulsions in which droplets of a first liquid are dispersed throughout a continuous phase composed of a second liquid with which the first liquid is immiscible, and continuous liquid phases throughout which solid particles are distributed.As used herein, the term emulsion encompasses continuous liquid phases throughout which gas bubbles are distributed, continuous liquid phases throughout which solid particles (e.g., solid catalyst) are distributed, continuous phases of a first liquid throughout which droplets of a second liquid substantially insoluble in the continuous phase are distributed, and liquid phases throughout which any one or a combination of solid particles, immiscible liquid droplets, and gas bubbles are distributed. Therefore, an emulsion can exist as a homogeneous mixture in some cases (e.g., liquid / liquid phase), or as a heterogeneous mixture (e.g., gas / liquid, solid / liquid, or gas / solid / liquid), depending on the nature of the materials selected for combination.
[0039] As used herein, the term stable or stability refers Petition 870260042611, dated 06 / 05 / 2026, page 16 / 250 13 / 109 refers to the water-in-silicone emulsion as described herein. Stability may refer to the ability of the emulsion to resist changes in its properties over time under appropriate storage conditions. For example, stability may typically mean that the composition does not separate phase when stored at room temperature (e.g., approximately 20°C to 25°C) for at least 1 month, or when stored in its final packaging at room temperature (e.g., approximately 20°C to 25°C) for at least 12 months. Other exemplary stability characteristics include the stability of the final packaged product in terms of expiration.For example, stability can mean that the constituents of the product (e.g., active or inactive ingredients) have not altered, degraded, or decomposed the product's properties (e.g., emulsion stability, zero-rate viscosity) as defined in its Certificate of Analysis, the product's preservation system remains functional, or any combination of these has not been altered. The stability of emulsions can be characterized using techniques described herein, including, for example, light scanning, optical microscopy, freeze / thaw cycles, centrifugation, and rheology.
[0040] Furthermore, as used herein, stable or stability refers to the composition comprising the water-in-silicone emulsion described herein (e.g., the composition comprising the emulsion and additional agents described herein in the stable composition). For example, the composition may include carrier(s) and / or other materials suitable for the composition to comprise a variety of active agents (e.g., active ingredients), and wherein the active agents will be stable for a long period of time as described herein. In addition, the active agent, according to some configurations, must be stable for a period of time in Petition 870260042611, dated 06 / 05 / 2026, page 17 / 250 14 / 109 composition as described here.
[0041] As used in the context of the composition of this disclosure, the term stable means physical and chemical stability. Chemical stability refers to chemical changes in an active or inactive agent (e.g., degradation of agents, oxidation of agents). In the settings of this disclosure, the storage or shelf life of a composition is a measure of chemical stability. Physical stability refers to the mechanical properties, physical state (e.g., crystallinity, crystal structure) and release properties of the active agent (or drug).
[0042] Stability is measured after storing the composition of this disclosure under temperature and relative humidity (RH) conditions of approximately 25°C / 60% RH to approximately 40°C / 75% RH. Accelerated time and real-time shelf-life testing of the composition is performed in order to confirm the shelf life and determine the product expiration date. In addition, the shelf life of the composition is also tested under expected packaging conditions.
[0043] The stability of the composition should be understood as meaning the maintenance of the homogeneous appearance of the composition, without phase separation, precipitation or flocculation of particles, for at least 6 months at 25°C. In other configurations, the composition is stable for at least 9 months, at least 12 months, at least 18 months, or at least 24 months at 25°C.
[0044] As used herein, the term cream may refer to a thick liquid (high zero-rate viscosity), semi-liquid or semi-solid formulation, which may be used for the therapeutic treatment of a disease, syndrome or condition (i.e., a vulvovaginal disease, syndrome or condition).
[0045] As used herein, the term lotion may refer to a moderately thick liquid (zero viscosity rate mo Petition 870260042611, dated 06 / 05 / 2026, page 18 / 250 15 / 109 derada) semiliquid or semisolid formulation, which can be used for the therapeutic treatment of a disease, syndrome or condition (i.e., a vulvovaginal disease, syndrome or condition).
[0046] As used herein, the term ointment may refer to a highly viscous liquid or semi-liquid formulation that may be used for the therapeutic treatment of a disease, syndrome or condition (i.e., a vulvovaginal disease, syndrome or condition).
[0047] Liquid as used herein is a dosage form consisting of a composition in its liquid state. A liquid can be poured; it flows and conforms to its container at room temperature. Liquids exhibit Newtonian or pseudoplastic flow behavior. In configurations, a semiliquid or semisolid, as used herein, may have properties of both a liquid and another formulation (i.e., a dispersion, a suspension, an emulsion, a lotion, a cream, and the like).
[0048] The term humectant, as used herein, refers to improving the hydration of a surface, such that the water-binding capacity of the surface increases. The term to wet, or derivatives thereof, refers to the conversion or enhancement of the water content of an individual's surfaces.
[0049] As used herein, zero-rate viscosity refers to the resistance of a fluid or semi-solid to flow when the shear rate approaches zero.
[0050] In the descriptions above and in the claims, phrases such as at least one or one or more may occur followed by a conjunctive list of elements or characteristics. The term and / or may also occur in a list of two or more elements or characteristics. Unless otherwise implicitly or explicitly contradicted by the context in which it is used, such a phrase means any of the elements or characteristics listed individually or Petition 870260042611, dated 06 / 05 / 2026, p. 19 / 250 16 / 109 any of the cited elements or features in combination with any of the other cited elements or features. For example, the sentences at least one of A and B; one or more of A and B; and A and / or B are each intended to mean A only, B only, or A and B together. A similar interpretation is also intended for lists including three or more items. For example, the sentences at least one of A, B, and C; one or more of A, B, and C; and A, B, and / or C are each intended to mean A only, B only, C only, A and B together, A and C together, B and C together, or A and B and C together. Furthermore, the use of the term based on, above, and in the claims, means based at least in part, such that an unsolicited feature or element is also permitted.
[0051] By mitigating, it is understood to decrease, suppress, attenuate, diminish, halt or stabilize the development or progression of a disease or condition such as, for example, a pseudoallergic reaction.
[0052] The terms subject, patient, individual, and the like, as used herein, are not intended to be limiting and may generally be interchangeable. An individual described as a subject, patient, individual, and the like, does not necessarily have a particular disease but may simply be seeking medical advice. The terms subject, patient, individual, and the like, as used herein, include all members of the animal kingdom who may suffer from the indicated disorder. In some respects, the subject is a mammal, and in some respects, the subject is a human being.
[0053] The term "around" when used in reference to the site of administration of the vulvovaginal compositions described should be understood by those skilled in the art to mean administered to the anatomical area of interest, within the limits of traditionally practiced procedures. For example, administration around the site Petition 870260042611, dated 06 / 05 / 2026, page 20 / 250 17 / 109 anatomically relevant refers to a location that is not directly within or on the site, but sufficiently close to the site to provide a physiologically or therapeutically relevant effect. Those commonly skilled in the art can readily determine the maximum distance from a given anatomical site that will be sufficient to provide a physiologically or therapeutically relevant effect using a vulvovaginal composition according to the present disclosure.
[0054] Pharmaceutically acceptable refers to those properties and substances that are acceptable to the patient from a pharmacological / toxicological point of view and to the pharmaceutical manufacturing chemist from a physical / chemical point of view in relation to composition, formulation, stability, patient acceptance and bioavailability.

[00110] The disclosed compositions may include one or more active agents to provide symptom relief or treat the underlying pathophysiology, or protect the individual's anatomy (e.g., rectum). Suitable classes of active agents include, but are not limited to, vasoconstrictors, anti-inflammatory drugs, steroids, local anesthetics, alpha-adrenergic receptor agonists, onabotulinumtoxin A, calcium channel blockers, nitrates, or any combination thereof.
[00111] One or more active agents may be incorporated within the emulsion. In some configurations, one or more active agents are incorporated within the aqueous phase of the emulsion. In other configurations, one or more active agents are incorporated within the silicone phase of the emulsion. In other configurations, one or more active agents are incorporated within both the aqueous and silicone phases of the emulsion.
[00112] In some configurations, the active agent may be formulated to be present in a typical amount for such an agent. For example, the agent may be formulated to make up to 0.01% in Petition 870260042611, dated 06 / 05 / 2026, page 41 / 250 38 / 109 by weight, inclusive, of the composition. In some configurations, the active agent may be formulated to comprise up to 0.025% by weight, inclusive, of the composition. In some configurations, the active agent may be formulated to comprise up to 0.05% by weight, inclusive, of the composition. In some configurations, the active agent may be formulated to comprise up to 0.1% by weight, inclusive, of the composition. In some configurations, the active agent may be formulated to comprise up to 1% by weight, inclusive, of the composition. In some configurations, the active agent may be formulated to comprise up to 2% by weight, inclusive, of the composition. In some configurations, the active agent may be formulated to comprise up to 4% by weight, inclusive, of the composition. In some configurations, the active agent may be formulated to comprise up to 6% by weight, inclusive, of the composition. In some configurations, the active agent may be formulated to comprise up to 8% by weight, inclusive, of the composition.In some configurations, the active ingredient can be formulated to comprise up to 10% by weight of the composition.
[00113] Throughout this disclosure, the term "active agent" may refer to more than one active agent if more than one of these agents is present in the composition. For example, when only one active agent is incorporated within the emulsion, a reference to 50% by weight of the active agent means that 50% of the single active agent is present. When more than one active agent is incorporated within the emulsion, the language referring to 50% by weight of the active agent means that 50% of the total complement of active agents is incorporated within the emulsion. Thus, if the composition includes 1 mg of one active agent and 1 mg of a second active agent, then 50% by weight preservative may mean that 50% of the total complement of 2 mg of active agents is incorporated within the emulsion.
[00114] The compositions of the present invention may contain a Petition 870260042611, dated 06 / 05 / 2026, p. 42 / 250 39 / 109 safe and effective quantity of a conditioning agent, for example, humectants, emollients, moisturizers and skin conditioners.

[00134] As described herein, certain aspects of the present invention relate to the use of the compositions to make cosmetics, personal care products, feminine care products, hygiene products, dermatological products, ophthalmic products, pharmaceutical preparations or medicines for maintaining healthy skin, skin rejuvenation, restoration of damaged skin, including, but not limited to, cosmetics on the skin after aesthetic and dermatological procedures, wound healing, treatment of atrophy of any human tissue, including vulvovaginal atrophy, and / or other skin and mucous membrane conditions, disorders and diseases in humans associated with alterations in extracellular matrix components.
[00135] This is done by topical application of the composition of the invention to the skin or mucous membrane of the human being requiring such treatment. In some limited cases, this can be done by topical administration of the composition of the invention to a human being requiring such treatment.
[00136] Certain aspects of the present invention also relate to methods of using such compositions for treatment or prevention in dermatological applications, as well as for improving wound healing, reducing atrophy of any human tissue, including vulvovaginal atrophy, and for improving other conditions, disorders and diseases of the skin and mucous membranes in humans. These methods generally involve applying the composition topically to the affected skin. Petition 870260042611, dated 06 / 05 / 2026, page 51 / 250 48 / 109 or to the affected anatomy when necessary, in the quantity and frequency most appropriate for the purpose. Methods to prevent, delay the onset of, or treat a skin or mucosal condition, disorder, or disease are also contemplated.
[00137] Those skilled in the art may further recognize that the administration of any of the compositions and / or formulations of the invention treats, relieves or alleviates skin and mucous membrane conditions, disorders and diseases in humans, for example, injured skin, damaged skin after aesthetic and dermatological procedures, skin and mucous membrane atrophy due to causes other than aging (for example, emotional stress, use of oral contraceptive pills, use of aromatase inhibitors, due to surgery, etc.), and for other skin and mucous membrane conditions, disorders and diseases in humans. Vulvovaginal compositions
[00138] Vulvar and vaginal atrophy (VVA), resulting from the loss of estrogen stimulation in vaginal and vulvar tissue, is a common medical condition in peri- and postmenopausal women. VVA often manifests with discomfort, which may be experienced as vaginal dryness, lack of lubrication, roughness, burning, irritation, inflammation, atrophic vaginitis, dyspareunia (pain during sexual intercourse), and general pain. VVA occurs most frequently after menopause, but can also develop during breastfeeding, as a consequence of breast cancer treatment, or at any other time when a woman's estrogen production decreases. Furthermore, recent evidence indicates that women taking oral contraceptives (which can cause a decline in the production of certain sex hormones, such as testosterone) may also experience vulvovaginal atrophy. VVA will occur in most postmenopausal women at some point in their lives. It is estimated that Petition 870260042611, dated 06 / 05 / 2026, page 52 / 250 49 / 109 There are 64 million postmenopausal women in the United States, and about 32 million women may suffer from VVA symptoms.
[00139] Existing non-prescription treatments (e.g., non-hormonal, over-the-counter (OTC) moisturizing and lubricating creams) have shortcomings in several areas, for example, they are not able to restore stasis to anatomy and physiology; they often contain ingredients that are not well tolerated in the vaginal canal; they are often not isotonic; and they are far inferior to Hormone Replacement Therapies (HRT) in terms of symptom relief and treatment of the underlying pathology.
[00140] The pathophysiology of VVA is such that decreasing estrogen levels, associated with peri- and post-menopause, cause (1) a thinning of the superficial cells and stratified epithelial cells lining the vaginal mucosa, and (2) a decrease in squamous epithelial glycogenation, resulting in a decrease in exfoliated and glycogenated cells. Glycogen is an important biomolecule responsible for maintaining vaginal health. The conversion of glycogen to lactic acid by lactobacilli, the beneficial flora of the vaginal mucosa, is essential for maintaining a healthy and low vaginal pH. In the absence of glycogen, vaginal pH increases, resulting in a decrease in lactobacilli and a potential for overgrowth of harmful bacteria, which can lead to infection and inflammation. Furthermore, the decline in estrogen levels leads to decreased vulvovaginal blood flow, decreased mucus production, and decreased vaginal lubrication.Thus, compositions and methods are provided here that address these needs. Vulvovaginal compositions (e.g., lubricants, moisturizers, creams) are provided here that are non-hormonal, isotonic, long-lasting, and capable of slowing the progression of VVA (e.g., by restoring pH balance, providing significant lubrication, and providing symptom relief - dryness). Petition 870260042611, dated 06 / 05 / 2026, page 53 / 250 50 / 109 vaginal - for at least 24 hours from a single application), and comprise only well-tolerated, generally recognized as safe (GRAS) ingredients that are compatible with latex lactobacilli.

Example 3: Vulvovaginal cream prepared by water-in-silicone (W / O) emulsification. Methods
[00265] A water-emulsified silicone cream was manufactured using a high-shear mixing method, utilizing a Silverson rotor-stator homogenizer. Briefly, an aqueous dispersing phase comprising 36.4 wt% of lactic acid buffer system (100 mM lactic acid / sodium lactate buffer, pH 3.8, 300 mOsm / kg), and 0.1 wt% glycogen, was prepared by Petition 870260042611, dated 06 / 05 / 2026, page 102 / 250 99 / 109 Dissolving the components in deionized water, with stirring at 80°C (the deionized water was compensated to account for evaporative loss during heating). A continuous silicone phase, comprising 13 wt% 2-octyldodecanol, 0.25 wt% Span 60, 2 wt% cholesterol, 0.2 wt% stearic acid and 0.1 wt% tocopheryl acetate, was prepared by dissolving these components in a mixture of 35.65 wt% dimethicone and 12.3 wt% dimethicone / dimethiconol, with stirring at 80°C. The resulting aqueous dispersing phase (80°C) was added to the resulting continuous silicone phase (80°C), under constant high shear stirring, using a Silverson rotor-stator homogenizer, operating at 6500 RPM, for 10 minutes. The emulsification shear rate was then increased to 8000 RPM for 5 minutes, to yield a solidified water-in-silicone emulsified cream.The stable microemulsion was then transferred to an air stirrer for equilibration cooling at room temperature to yield a stable, solidified water-in-silicone emulsion cream. All weight percentages of the constituents represent percentages of the total composition. Rheology: Flux voltage sweep protocol

[00269] The formulations were generated according to Table 1 and analyzed using macroscopic and microscopic optical imaging to determine stability. Formulation #1 yielded a white, moderately viscous cream in the absence of classic emulsion, which was stable. Phase separation began on day 10 and a progressive increase was observed. Formulation #2 yielded a white cream with higher viscosity in the absence of stable classic emulsion. The higher viscosity was attributed to the incorporation of dimethiconol. Phase separation began Petition 870260042611, dated 06 / 05 / 2026, page 106 / 250 Formulation #3 yielded a viscous white cream in the absence of a stable, classic emulsion. Phase separation was initially observed on day 1, indicating the existence of an upper limit to cholesterol incorporation. Formulation #4 failed to yield both a viscous white cream and a stable, classic emulsion. Phase separation was observed immediately after emulsification, indicating the existence of an upper limit to Span 60 incorporation. This phenomenon was likely correlated with the Span 60 concentration being above the critical micelle concentration (CMC) of Span 60 in the mixed silicone. Formulation #5 yielded a viscous white cream in the absence of a stable, classic emulsion. Phase separation began on day 14 and a progressive increase was observed.This phenomenon was likely correlated with the increase in 2-octyldodecanol, creating a better interface with Span 60 and cholesterol, to better stabilize the water droplets at the water-silicone interface. Formulation #6 yielded a viscous white cream, in the absence of a stable, classic emulsion. Phase separation began on day 4 and a progressive increase was observed. This phenomenon indicated that attempting to physically stabilize the emulsion by increasing the waxy component and dimethiconol is futile; therefore, the stability of the emulsion is predominantly governed by physicochemical and thermodynamic parameters. Formulation #7 yielded a viscous white cream, in the absence of a stable, classic emulsion. Phase separation began on day 5 and a progressive increase was observed. This phenomenon indicated the usefulness of decreasing the concentration of Span 60.Formulation #8 yielded a viscous white cream in the presence of a more consistent emulsion with a stable, classic emulsion (Figure 3A-3C). Exudation of the silicone phase was observed on day 6, although the emulsion maintained moderate stable integrity. Phase separation began on day 15 and an increase in pro- Petition 870260042611, dated 06 / 05 / 2026, page 107 / 250 104 / 109 progressive. This phenomenon further supports the hypothesis that a specific balance of emulsifiers is essential to confer stability to the emulsion. Furthermore, the exudation of the oil phase indicated that the water-to-silicone ratio should be altered to incorporate a more aqueous dispersing phase. Formulation #9 yielded a viscous white cream in the presence of a stable, classic emulsion (Figure 4A4C). This cream showed no signs of phase separation or instability, confirming the importance of the water-to-silicone ratio for emulsion stability. Formulation #10 (Figure 5A-5C) and Formulation #11 also yielded a viscous white cream in the presence of a stable, classic emulsion. These creams showed no signs of phase separation or instability. Formulation #12 yielded a viscous white cream in the absence of a stable, classic emulsion. This phenomenon demonstrated the importance of controlling the constituents of the silicone phase.Formulation #13 also yielded a viscous white cream in the presence of a stable, classic emulsion. Removing the cholesterol from Formulation #13 to create Formulation #14 resulted in complete phase separation and a lack of emulsion formation (Figures 6A-6E). This phenomenon demonstrated the importance of cholesterol as an emulsifier and interfacial stabilizer.
[00270] The mechanical properties of the selected formulations were examined by rheometry and the results are summarized in Table 2 below.

[00271] Using a flow stress sweep protocol, zero-rate viscosities of 95 kPa.s and 105 kPa.s were determined at 25°C and 37°C, respectively, for Formulation #9 (Figure 7A-7D). An oscillatory frequency sweep showed a mostly parallel relationship between the storage modulus (G') and the loss modulus (G), with some convergence at high frequency (Figure 8A-8B). Furthermore, no amplification or hysteresis was observed throughout the frequency domain, and the difference between G' and G at 25°C and 37°C was found to be negligible. An oscillatory amplitude sweep showed only a small difference between the crossover points of G' and G and the stresses at 25°C and 37°C, thus indicating that the solid-to-liquid transition is similar across the defined temperature range (Figure 9A-9B). An oscillatory temperature scan revealed a slight negative slope for G', G and complex viscosity (Figure 10).Furthermore, this provided further evidence supporting the negligible differences in Formulation #9 at 25°C and 37°C. Taken together, these rheological properties demonstrate ideal properties for a vulvovaginal cream designed to be stored at room temperature and applied to the anatomy at body temperature. These ideal properties were also observed in Formulation #11.
