Description

Cosmetic products containing a discontinuous oil phase and methods of use thereof

Technical Field

The present invention relates to a cosmetic product comprising a cosmetic composition comprising an aqueous phase and an initial oil phase, wherein the cosmetic composition is contained in a container; wherein the product further comprises a mark for a user to shake the container; wherein, by shaking, the composition is designed to break up the initial oil phase into a discontinuous oil phase dispersed in the aqueous phase, wherein the discontinuous oil phase has a particle size of about 0.01 mm to about 20 mm, wherein the discontinuous oil phase is dispersed for at least 24 hours. The cosmetic product of the present invention provides extended dispersion of the dispersed oil phase. The present invention also relates to methods of use thereof.

Background Art

Mammalian keratinous tissue, particularly human skin, is subject to multiple violations of both external and internal factors. Such external factors include ultraviolet radiation, environmental pollution, wind, heat, infrared radiation, low humidity, irritating surfactants, abrasives, etc. On the other hand, internal factors include time course aging and other biochemical changes in the skin. Whether external or internal, these factors all lead to visible signs of skin damage. Typical skin damage in aging or damaged skin includes fine lines, wrinkles, hyperpigmentation, sallow, sagging, dark circles, swollen eyes, enlarged pores, reduced renewal rate and abnormal desquamation or peeling. Additional damage caused by both external and internal factors includes visible dead skin, i.e. flaking, scaling, dryness and roughness.

Currently, there are many personal care products available to consumers that are intended to improve the health and physical appearance of keratinous tissues such as skin, hair, and nails. Most of these products involve delaying, minimizing, or even eliminating skin wrinkles, spots, and other histological changes that are typically associated with skin aging or environmental damage to human skin. Consumers prefer topically applied products because they are not only effective, but also safe and pleasant to use.

For example, there are some dual-phase products that contain both an oil phase and an aqueous phase in one bottle, wherein the oil phase typically floats on the surface of the aqueous phase, and consumers are advised to shake the bottle prior to use to disperse the oil phase in the aqueous phase. Some of these oil dispersions are visible. However, such oil phase dispersions are typically only visible for a few hours. There is a need for such dual-phase products that can maintain the dispersed oil phase for a longer period of time.

On the other hand, the use of polymer encapsulated and/or oil-absorbing porous particles is known in view of the continuous dispersion and/or visible dispersion of the oil phase in the aqueous phase. However, in order to include a certain amount of oil in the composition, it is necessary to use relatively high amounts of such polymer encapsulated and/or oil-absorbing porous particles. There is also a need for oil dispersions to remain longer and/or visible without the use of polymer encapsulated and/or oil-absorbing porous particles.

Based on the foregoing, there exists a need for a cosmetic product that provides for prolonged dispersion of a dispersed oil phase, especially for prolonged dispersion of a visible dispersed oil phase, especially without the use of polymer encapsulation and/or oil absorbing porous particles for dispersion.

Summary of the invention

A method of using a cosmetic product, wherein the cosmetic product comprises a cosmetic composition comprising an aqueous phase and an initial oil phase, wherein the cosmetic composition is contained in a container; wherein the method comprises the step of shaking the container to break up the initial oil phase into a discontinuous oil phase dispersed in the aqueous phase, wherein the discontinuous oil phase has a particle size of about 0.01 mm to about 20 mm, and wherein the discontinuous oil phase is dispersed for at least 24 hours. The method of the present invention provides for extended dispersion of the dispersed oil phase.

Initial oil phase

The initial oil phase can be any shape in the continuous water phase, for example, it can be a phase floating in the continuous water phase, several or several separated phases in the continuous water phase. The separated phase can be a spherical droplet dispersed in a continuous aqueous carrier. Alternatively, the separated phase with a certain viscosity can be shaped as a non-spherical shape, for example, shaped and pressed on the inner wall of a container. Depending on the viscosity, desired shape and/or purpose of the initial oil phase, the initial oil phase can be introduced into the container by injection, pouring and/or pressing.

Discontinuous oil phase

The discontinuous oil phase is dispersed in the water phase, and the particle size of the discontinuous oil phase is smaller than the particle size of the initial oil phase and is from about 0.01 mm to about 20 mm, or from 0.05 mm to about 10 mm, or from about 0.1 mm to 5 mm. The discontinuous oil phase is dispersed for at least 24 hours, at least 3 days, at least 5 days, or at least 1 week. The particle size used herein means the average particle size based on volume.

No polymer encapsulation

The composition is free of polymer encapsulation. Polymer encapsulation herein refers to encapsulation having a polymer shell encapsulating an internal material.

Any oily component may be used herein. The oily component may satisfy the following conditions named "physical parameters of the phase". In the example where two or more oily components are used as a mixture in the oil phase, the mixture may satisfy such conditions. In some examples, a solid oily component may be used as a mixture with a liquid oily component as long as it fluidizes as an oil phase when shaken. A liquid oily component may be used, and such a liquid oily component may have a melting point of 15°C or less, or 10°C or less, or 0°C or less.

Representative oily components useful herein include, for example, isohexadecane (density of about 0.79 g/ml), isopropyl palmitate (density of about 0.86 g/ml), isopropyl isostearate (density of about 0.86 g/ml), caprylic/capric triglyceride (density of about 0.91 g/ml), isopropyl lauroyl sarcosinate (density of about 0.94 g/ml), triethylhexanoin (density of about 0.96 g/ml), and dimethicone 50 cst (density of about 0.97 g/ml).

Combinations of such incompatible ingredients are, for example: niacinamide and vitamin A or a derivative thereof (eg, retinyl propionate); niacinamide and changes in pH (<4 or >7); water and vitamin C or a derivative thereof.

For example, when retinol propionate is included in the continuous aqueous phase, by adding niacinamide to the oil phase, the cosmetic composition can reduce the interaction between niacinamide and retinol propionate and can slow down an undesirable chemical reaction of at least one of these ingredients.

High oil absorption solid particles

The initial oil phase and the dispersed discontinuous oil phase are substantially free of solid particles having an oil absorption rate of 300 ml/100 g or more, or an oil absorption rate of 250 ml/100 g or more. "The oil phase is substantially free of high oil absorption solid particles" may mean that the oil phase does not contain high oil absorption solid particles; or, if the oil phase contains high oil absorption solid particles, the content of such high oil absorption solid particles is very low. The composition may have a total content of such high oil absorption solid particles (if included) of 5% or less, or 3% or less, or 1% or less, or 0.5% or less. In some examples, the total content of such high oil absorption solid particles is 0% by weight of the oil phase.

Low oil absorption solid particles

The oil phase may contain solid particles having a low oil absorption, ie, an oil absorption of at most about 250 ml/100 g, or at most about 200 ml/100 g or less, or at most about 150 ml/100 g or less.

Such low oil absorption solid particles include, for example, some silicone elastomers, such as the elastomer with the trade name KSP-100; some silica, such as mica with the trade name GoddBall G-6C (oil absorption 30 ml/100 g) and GoddBall D-25C (oil absorption 90 ml/100 g); TiO ₂ ; iron oxide;

Any percentage as long as the oil phase has viscosity.

Other ingredients in the oil phase

The oil phase may contain one or more other ingredients known for use in topical cosmetic compositions, provided that such other ingredients do not unacceptably alter the desired benefits and/or properties of the oil phase. Such other ingredients include, for example, those described under the name "other ingredients".

Regardless of hydrophobicity/hydrophilicity, any ingredient may be added as long as such ingredient does not prevent/interfere with the formation and dispersion of the discontinuous oil phase. Any water-soluble, partially water-soluble ingredient (such as an ingredient having a water solubility of about 0.5 g/L or more at 25° C.), water-insoluble chemical substance may be added. In some examples, if water-soluble, partially water-soluble ingredients (such as an ingredient having a water solubility of about 0.5 g/L or more at 25° C.) are included, these ingredients are solid at room temperature.

Representative other ingredients in the oil phase include, for example:

Water/oil insoluble particles such as mica, titanium dioxide, silicone elastomer powders;

Water-soluble solid materials such as niacinamide, vitamin C, and vitamin C derivatives.

When a water-soluble solid material is added, the water-soluble solid material can gradually diffuse into the continuous aqueous phase.

Color and/or refractive index

In order to provide aesthetic benefits, the color and/or refractive index of the initial oil phase and the discontinuous oil phase may be different from the color and/or refractive index of the water phase. In some examples, the difference in refractive index between the oil phase and the water phase is 0.03 or greater.

Physical parameters of phase

The water phase and the oil phase may satisfy the physical parameters shown in the following Table 1. Details of each parameter are described below.

Table 1

Table 1 shows:

(1) When the density difference between the water phase and the oil phase is greater than 0.18 (excluding 0.18) and 0.40, the water phase satisfies one of the following conditions:

(1-1) When the aqueous phase contains a hydrophilic thickener having no associative ability to oil, the aqueous phase preferably has a G'max.>5 and a crossover point (CP);

(1-2) When the aqueous phase contains a hydrophilic thickener having an associative ability with oil, the aqueous phase preferably has G'max.＞1;

(1-3) When the aqueous phase contains both: a hydrophilic thickener having no associative ability to oil; and a hydrophilic thickener having associative ability to oil, the aqueous phase preferably has a G'max.＞2.5;

(2) When the density difference between the water phase and the oil phase is 0 to 0.18, the water phase satisfies one of the following conditions:

(2-1) When the aqueous phase contains a hydrophilic thickener having no associative ability to oil, the aqueous phase preferably has G'max.＞4, more preferably G'max.＞5, and preferably has a crossover point (CP);

(2-2) When the aqueous phase contains a hydrophilic thickener having an associative ability to oil, the aqueous phase preferably has G'max.＞0, more preferably G'max.＞1;

(2-3) When the aqueous phase contains both: a hydrophilic thickener having no associative ability to oil; and a hydrophilic thickener having associative ability to oil, the aqueous phase preferably has G'max.＞0, more preferably G'max.＞2.5.

Elasticity values G’max. and G”

The water phase may have a certain "G'max." value, which depends on the type of hydrophilic thickener contained in the water phase and also on the density difference between the water phase and the oil phase. In consideration of keeping the oil dispersed for a longer time, the detailed values of such preferred "G'max." are shown in Table 1.

The elasticity values G'max. and G" are measured by using the exact composition of the water phase, which contains all the ingredients used in the water phase. The measuring method and conditions are as follows, and the same method and conditions apply to the measurement of the crossover point (CP) described below:

Crossover Point (CP)

The crossover point is the position where G' and G" cross. As shown in Table 1, when the aqueous phase contains a hydrophilic thickener (the thickener has no associative ability to oil), especially when the aqueous phase does not contain a hydrophilic thickener having associative ability to oil, it is preferred that the aqueous phase have this crossover point in view of retaining the oil dispersion for a longer period of time.

Density difference

Considering that the discontinuous oil phase is dispersed for a longer time, the density of the oil phase and the water phase can have a certain difference, as shown in Table 1.

The density of the oil phase is measured by using the exact composition of the oil phase, which contains all the ingredients used in the oil phase but does not include the solid particles used in the oil phase.

The density of the aqueous phase is measured by using the exact composition of the aqueous phase which contains all ingredients used in the aqueous phase but excludes those dispersed ingredients and those ingredients which do not form a continuous phase with the aqueous carrier if such ingredients are used in the aqueous phase.

Density is measured at 20°C-25°C.

Viscosity of oil phase

The initial oil phase and the dispersed discontinuous oil phase may have the following viscosities:

When the oil phase is a Newtonian oil phase, the viscosity is from about 1 cps to about 20,000 cps, or from about 1 cps to about 10,000 cps; and

When the oil phase is a non-Newtonian oil phase, the viscosity is from about 1 cps to about 300,000 cps, or from about 1 cps to about 200,000 cps, or from about 2 cps to about 100,000 cps.

This viscosity, together with the viscosity of the water phase, helps the initial oil phase to disperse into a dispersed discontinuous oil phase when shaken.

The viscosity of the initial oil phase and the dispersed discontinuous oil phase are measured by using the exact composition of these oil phases, which contains all the ingredients used in these oil phases.

The measurement methods and conditions are as follows:

Brookfield RV viscometer, T bar, (T-A bar for low viscosity, T-E for high viscosity), at room temperature, spindle speed equal to 5 rpm for both Newtonian and non-Newtonian oil phases.

Viscosity of the water phase

The aqueous phase may have a viscosity of about 100 cps to about 50,000 cps, or about 100 cps to about 30,000 cps.

The viscosity of the water phase is measured by using the exact composition of the water phase containing all the ingredients used in the water phase.

The measurement methods and conditions are as follows:

Brookfield RV viscometer, T bar (T-A bar for low viscosity, T-E for high viscosity), spindle speed equal to 5 rpm, at room temperature.

Method of using the cosmetic composition

The method of use herein includes identifying the target skin part of a person that needs to be treated, and applying the composition to the target skin part during the treatment period. The target skin part can be on the surface of the facial skin (such as the forehead, perioral, chin, periorbital, nose and/or cheek) or another part of the body (such as hands, arms, legs, back, chest). The person who needs to be treated is a person whose skin shows signs of oxidative stress (such as fine lines, wrinkles, hyperpigmentation, uneven skin tone and/or other visible skin features that are usually associated with aging). In some cases, the target part of the skin may not show visible signs of skin aging, but if the area is an area where such problems usually occur as people age, users (such as relatively young users) may still wish to target such skin areas. In this way, the present method can be used as a preventive measure to delay the occurrence of visible signs of skin aging.

Can be during the treatment period to the target skin part, and if necessary, to the surrounding skin at least once a day, twice a day or in a more frequent number of times a day, apply composition.When twice a day, use for the first time and the second time at least 1 to 12 hours apart.Usually, composition can be used in the morning and/or before going to bed at night.The treatment period can last at least 1 week (for example, about 2 weeks, 4 weeks, 8 weeks or even 12 weeks).In some cases, the treatment period will extend multiple months (i.e. 3 months to 12 months).In some cases, composition can be used at most times in a week (for example, at least 4 days, 5 days or 6 days per week), at least once a day or even twice a day during the treatment period of at least 2 weeks, 4 weeks, 8 weeks or 12 weeks.

The step of applying the composition can be achieved by topical application. With regard to the application of the composition, the term "topical", "local", "topically" refers to delivering the composition to a target area (e.g., wrinkles or fine lines) while minimizing delivery to skin surfaces that are not desired to be treated. The composition can be applied to and gently rubbed into the skin area. The form of the composition or dermatologically acceptable carrier should be selected to facilitate topical application. Although certain embodiments herein contemplate that the composition is topically applied to a certain area, it should be understood that the composition herein can be widely applied to one or more skin surfaces. In certain embodiments, the composition herein can be used as part of a multi-step beauty regimen, wherein the composition of the present invention can be applied before and/or after one or more other compositions.
