Description

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

Background

Mammalian keratinous tissue, particularly human skin, is subject to a variety of aggressions, both extrinsic and intrinsic. Such external factors include ultraviolet radiation, environmental pollution, wind, heat, infrared radiation, low humidity, irritating surfactants, abrasives, and the like. On the other hand, intrinsic factors include chronological aging and other biochemical changes within the skin. These factors, whether extrinsic or intrinsic, lead to visible signs of skin damage. Typical skin lesions in aged or damaged skin include fine lines, wrinkles, hyperpigmentation, sallowness, sagging, dark circles, swollen eyes, enlarged pores, reduced turnover rates, and abnormal desquamation or desquamation. Additional damage caused by both external and internal factors includes visible dead skin, i.e., flaking, scaling, drying, and roughening.

Currently, there are many consumer available personal care products that aim to improve the health and physical appearance of keratinous tissue, such as skin, hair, and nails. Most of these products are directed to retarding, minimizing or even eliminating skin wrinkles, spots, and other histological changes commonly 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 biphasic products that contain both an oil phase and an aqueous phase in one bottle, where the oil phase typically floats on the surface of the aqueous phase, and it is recommended for the consumer to shake the bottle to disperse the oil phase in the aqueous phase prior to use. Some of such oil dispersions are visible. However, such oil phase dispersions are typically observed for only a few hours. There is a need for such biphasic products that can maintain a 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 and/or visible dispersion of the oil phase in the aqueous phase. However, in order to include an amount of oil in the composition, it is desirable to use relatively high amounts of such polymer encapsulated and/or oil absorbing porous particles. There is also a need for oil dispersions that remain longer and/or visible without the use of polymer encapsulated and/or oil absorbing porous particles.

Based on the foregoing, there is a need for a cosmetic product that provides prolonged dispersion of a dispersed oil phase, particularly a visually dispersed oil phase, particularly without the use of polymer encapsulated and/or oil absorbing porous particles for dispersion.

Initial oil phase

The initial oil phase may be of any shape in the continuous aqueous phase, for example, it may be one phase floating in the continuous aqueous phase, several or several separate phases in the continuous aqueous phase. The separate phases may be spherical droplets dispersed in a continuous aqueous carrier. Or the separate phase having a certain viscosity may be formed into a non-spherical shape, for example formed and embossed on the inner wall of the container. Depending on the viscosity, desired shape and/or purpose of the initial oil phase, the initial oil phase may be introduced into the container by injection, pouring and/or stamping.

Combinations of such incompatible ingredients are, for example: nicotinamide and vitamin a or derivatives thereof (e.g., retinol propionate); nicotinamide and pH change (< 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 may reduce the interaction between niacinamide and retinol propionate, and may slow down the undesired 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 of 300ml/100g or more, or an oil absorption of 250ml/100g or more. "the oil phase is substantially free of high oil absorption solid particles" may mean: the oil phase does not contain high oil absorption rate solid particles; or if the oil phase contains high oil absorption solid particles, the content of the 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, i.e., an oil absorption of up to about 250ml/100g, or up to about 200ml/100g or less, or up to about 150ml/100g or less.

Such low oil absorption solid particles include: for example, some silicone elastomers, such as the elastomer sold under the trade name KSP-100; some silicas such as mica under the trade name GoddBall G-6C (oil absorption of 30 ml/100G) and under the trade name Godd Ball D-25C (oil absorption of 90 ml/100G); tiO ₂; iron oxide;

any percentage as long as the oil phase has a viscosity.

Other ingredients in the oil phase

The oil phase may comprise 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 "other ingredient" designation.

Whatever the hydrophobicity/hydrophilicity, any ingredient may be added so 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 0.5g/L or greater at 25 ℃), water-insoluble chemical may be added. In some examples, if water-soluble, partially water-soluble ingredients (such as ingredients having a water solubility of about 0.5g/L or greater at 25 ℃) 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 powder;

water-soluble solid materials such as nicotinamide, vitamin C derivatives.

The water-soluble solid material may gradually diffuse into the continuous aqueous phase when added.

Color and/or refractive index

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 aqueous phase in view of providing aesthetic benefits. In some examples, the refractive index difference between the oil phase and the water phase is 0.03 or greater.

The detail values of such preferred "G' max" are shown in table 1, considering that the oil is kept dispersed for a longer period of time.

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

The method comprises the following steps: oscillation stress scan method

Instrument: discovery HR-2 rheometer (TA instrument)

Geometry: 40mm 2.004 Cone plate, peltier Aluminium plate (PELTIER PLATE Aluminium)

Geometric gap setting: the trimming gap offset was 50 μm and the cutoff gap was 48. Mu.m

Conditioning-sample (step 1)

And (3) setting the temperature: 25 DEG C

Vibration-amplitude (step 2)

And (3) setting the temperature: 25 DEG C

Test parameters: the frequency is 1Hz, the logarithmic sweep, the stress is 1.0Pa to up to 100Pa, and the number of points per decimal is at least 10.

Cross Point (CP)

The intersection is the position where G' and G "intersect. As shown in table 1, when the aqueous phase contains a hydrophilic thickener having no associative ability with oil, particularly when the aqueous phase does not contain a hydrophilic thickener having associative ability with oil, it is preferable that the aqueous phase has such a 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 densities of the oil phase and the aqueous phase may 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 of the ingredients used in the aqueous phase, but excludes those dispersed and those that do not form a continuous phase with the aqueous carrier (if such ingredients are used in the aqueous phase).

The density is measured at 20℃to 25 ℃.

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 1cps to about 20,000cps, or from about 1cps to about 10,000cps; and

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

This viscosity, together with the viscosity of the aqueous phase, helps the initial oil phase to disperse upon shaking into a dispersed discontinuous oil phase.

The viscosities 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 of the ingredients used in these oil phases.

The measurement method and conditions are as follows:

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

Viscosity of aqueous phase

The aqueous phase may have a viscosity of about 100cps to about 50000cps, or about 100cps to about 30000 cps.

The viscosity of the aqueous phase is measured by using the exact composition of the aqueous phase, which contains all the ingredients used in the aqueous phase.

The measurement method and conditions are as follows:

At room temperature, the Brookfield RV viscometer, T bar (T-A bar means low viscosity, T-E means high viscosity) and spindle rotation equal to 5rpm.

Method of using cosmetic compositions

The methods of use herein include identifying a target skin portion of a person in need of treatment, and applying the composition to the target skin portion during a treatment period. The target skin portion may be on a facial skin surface (such as forehead, perioral, chin, periorbital, nose, and/or cheek) or another portion of the body (e.g., hand, arm, leg, back, chest). The person in need of treatment is one whose skin exhibits signs of oxidative stress, such as fine lines, wrinkles, hyperpigmentation, uneven skin tone, and/or other visible skin characteristics commonly associated with aging. In some cases, the targeted portion of skin may not exhibit visible signs of skin aging, but if the area is one where such problems typically occur as people age, the user (e.g., a relatively young user) may still wish to target such skin area. In this way, the present method can be used as a precaution to delay the occurrence of visible signs of skin aging.

The composition may be applied to the target skin portion during the treatment period and, if desired, to the surrounding skin at least once per day, twice per day, or more frequently per day. When administered twice daily, the first and second administrations are separated by at least 1 to 12 hours. Typically, the composition may be administered in the morning and/or in the evening just prior to sleep. The treatment period may last for at least 1 week (e.g., about 2 weeks, 4 weeks, 8 weeks, or even 12 weeks). In some cases, the treatment period will be extended by a number of months (i.e., 3 months to 12 months). In some cases, the composition may be administered most of the time in a week (e.g., at least 4, 5, or 6 days per week), at least once a day, or even twice a day, during a treatment period of at least 2, 4, 8, or 12 weeks.

The step of administering the composition may be accomplished by topical application. With respect to the administration of a composition, the terms "topical," "locally" refer to the delivery of the composition to a target area (e.g., wrinkles or fine lines) while minimizing the delivery to the skin surface where treatment is not desired. The composition may be applied to and gently rubbed into an area of skin. The form of the composition or dermatologically acceptable carrier should be selected to facilitate topical application. While certain embodiments herein contemplate topical application of the compositions to an area, it should be understood that the compositions herein may be broadly applied to one or more skin surfaces. In certain embodiments, the compositions herein may be used as part of a multi-step cosmetic regimen, wherein the compositions of the present invention may be applied before and/or after one or more other compositions.
