Description

COSMETIC COMPOSITION COMPRISING STABILIZED RETINOL

Domain of disclosure

The present disclosure relates to cosmetic compositions comprising stabilized retinol, and in particular to cosmetic compositions comprising retinol which do not require protective packaging to protect the stabilized retinol.

Context of the disclosure

The skin acts as a natural barrier between internal and external environments and therefore plays an important role in vital biological functions such as protection against mechanical and chemical injury, microorganisms, and ultraviolet damage. The health and appearance of the skin can therefore deteriorate due to environmental factors, genetic make-up, nutrition, and sun exposure.

Environmental pollution conditions are rapidly deteriorating and appear more and more in the daily lives of consumers around the world. Pollution damage to human skin is also increasingly evident. Human skin is also subjected to a variety of attacks by extrinsic factors such as ultraviolet (UV) radiation, environmental pollution, wind, heat, infrared radiation, low humidity, aggressive surfactants, abrasives, etc Recent studies suggest that in addition to UV radiation, other environmental factors contribute to the development of senile lentigo, especially air pollution. Eventually, these factors lead to visible signs of damage to the skin including small brown spots on the skin, especially in the elderly.

Typical skin damage includes fine lines, wrinkle formation, hyperpigmentation, sallowness, sagging, dark bags under the eyes, puffy eyes, enlarged pores, visible dead skin i.e. peeling, flaking, dryness, and roughness. Consumers want to slow the progression of skin damage and reduce the effects of aging, especially on the face and around the eyes. Radiant, clear skin looks youthful and is a sign of good health and vitality.

Consequently, there is a constant need for new and improved formulations that improve the health and visual appearance of the skin.

Detailed description of the disclosure

The present disclosure relates to cosmetic compositions comprising stabilized retinol, and in particular to cosmetic compositions comprising retinol which do not require specialized protective packaging to protect the stabilized retinol. The inventors have discovered that certain components in specific quantities allow cosmetic compositions in which stable retinol is incorporated, such that the cosmetic composition can be contained in a non-protective packaging. For example, cosmetic compositions can stabilize retinol such that the cosmetic composition does not exhibit phase separation and retains at least 75% by weight of the retinol after storage for 8 weeks at 45°C in a resistant glass container in the light.

Preferably, the cosmetic compositions do not undergo phase separation and retain about 80% by weight or more, about 82% by weight or more, about 84% by weight or more, about 86% by weight or more, about 88% by weight or more, about 90% by weight or more, about 92% by weight or more, about 94% by weight or more, about 96% by weight or more, 98% by weight or more, about 99% by weight or plus, or about 99.5% by weight or more retinol after storage for 8 weeks at 45°C in a light resistant glass container. The inventors were surprised that 100% by weight of the retinol was retained and no phase separation occurred after storage for 8 weeks at 45°C in a lightfast glass container for some embodiments of the composition cosmetic. In some instances, the cosmetic compositions exhibited no phase separation and retained approximately 80 wt% or more of the retinol after storage for 8 weeks at 45°C in a lightfast glass container comprising approximately 5 wt% or more of the retinol. less, for example, about 4 wt% or less, about 3 wt% or less, about 2 wt% or less, about 1 wt% or less, about 5000 ppm or less, about 1000 ppm or less , about 900 ppm or less, about 800 ppm or less, about 700 ppm or less, about 600 ppm or less, about 500 ppm or less, about 400 ppm or less, about 300 ppm or less, about 200 ppm or less, about 100 ppm or less, about 50 ppm or less, of oxygen in container. In additional instances, the cosmetic compositions exhibited no phase separation and retained about 80% by weight or more of the retinol after storage for 8 weeks at 45°C in a lightfast glass container and the cosmetic composition comprising 1 000 ppm or less oxygen, for example, about 900 ppm or less, about 800 ppm or less, about 700 ppm or less, about 600 ppm or less, about 500 ppm or less, about 400 ppm or less, about 300 ppm or less, about 200 ppm or less, about 100 ppm or less, about 50 ppm or less oxygen.

The cosmetic composition typically includes;

(a) about 0.01 to about 3% by weight retinol;

(b) about 0.5 to about 10% by weight sodium polyacrylate;

(c) about 0.25 to about 10% by weight of one or more nonionic emulsifiers;

(d) about 3.5 to about 12% by weight of a fat phase, wherein the fat phase comprises one or more fatty compounds; And

(e) water,

wherein the cosmetic composition is an oil-in-water emulsion, and all weight percentages are based on the total weight of the cosmetic composition.

Additionally, aspects of the disclosure relate to cosmetic compositions which have a reduced fatty phase. Typically, cosmetic compositions which attempt to provide stable retinol include substantial fatty phases in which retinol is dissolved. The inventors have, however, discovered that certain embodiments of the cosmetic compositions advantageously stabilize retinol, such that neither protective packaging nor a significant oil phase is necessary to stabilize the retinol therein. For example, the cosmetic compositions can include about 12% by weight or less of a fatty phase (for example, about 12% by weight or less of the total amount of fatty compounds). In some cases, the cosmetic composition includes a total amount of fatty compounds of about 12% by weight or less, about 10% by weight or less, about 9% by weight or less, about 8% by weight or less, about 7 % by weight or less, about 6% by weight or less, or about 5% by weight or less, based on the total weight of the cosmetic composition.

The cosmetic compositions can be packaged in a container containing a pump. The pump may be a standard push pump in some cases. Preferably, the container for the cosmetic composition is a non-protective packaging. For example, in some cases, the cosmetic composition is contained in a container that does not include an aluminum layer or another metallic layer that acts as an oxygen barrier. Examples of non-protective packaging include standard plastic containers, such as high density polyethylene (“HDPE”), low density polyethylene (“LDPE”), ethylene vinyl alcohol (“EVOH”), poly(ethylene terephthalate) (“PET”), poly(vinyl chloride) (“PVC”), polypropylene (“PP”), polystyrene (“PS”), or combinations thereof. Containers may include a pump, such as a push pump or an automatic pump.

The cosmetic composition is generally formulated as an emulsion. Typically, cosmetic compositions are formulated to be oil-in-water emulsions, the fatty phase being emulsified in the hydrophilic phase. However, in certain cases, the cosmetic compositions can be formulated to comprise a hydrophilic phase (for example, alcohols, glycols, polyols, etc.) emulsified in the fatty phase.

Additionally, the present disclosure relates to methods of treating the skin comprising applying the cosmetic composition of the present disclosure to the skin. The cosmetic compositions are further useful in methods of treating and/or repairing damage to skin due to photoaging, and diminishing the appearance of wrinkles, dark spots, and uneven skin texture . The aforementioned methods may be non-therapeutic.

Suitable components, such as those listed below, may be included or excluded from formulations for the cosmetic compositions depending on the specific combination of other components, the form of the cosmetic compositions, and/or the use of the formulation (e.g. , lotion, gel, cream, spray, etc.).

Emulsifiers are typically used to incorporate oil and/or fatty compounds into a hydrophilic medium, such as an aqueous medium, to form oil-in-water emulsions. In some cases, however, emulsifiers can be used to incorporate a hydrophilic phase (e.g. an aqueous medium) into an oily or fatty phase to form a water-in-oil emulsion. The cosmetic compositions include one or more nonionic emulsifiers. Additional emulsifiers, however, may also be included (or excluded), such as amphoteric, anionic, and/or cationic emulsifiers.

For O/W emulsions, examples of emulsifiers which may be mentioned include nonionic emulsifiers such as oxyalkylenated (more particularly polyoxyethylene) fatty acid esters of glycerol; oxyalkylenated fatty acid esters of sorbitan; oxyalkylenated (oxyethylenated and/or oxypropylene) fatty acid esters; oxyalkylenated (oxyethylenated and/or oxypropylene) fatty alcohol ethers; sugar esters such as sucrose stearate; and their mixtures. A more comprehensive but non-limiting list of useful nonionic emulsifiers is provided below under the heading "Nonionic Emulsifiers".

In some cases, cosmetic compositions containing natural oils include two or more nonionic emulsifiers. In particular, one or more nonionic emulsifiers having an HLB of 10 or more and one or more nonionic emulsifiers having an HLB of 5 or less. The total amount of these emulsifiers can be such that the final HLB of the hair treatment composition is within +/- 0.5 of the HLB of the natural oil in the cosmetic composition. This typically results in a final HLB of the emulsified natural oil in the hair treatment composition ranging from about 6 to about 8.

Examples of emulsifiers which may be mentioned include nonionic emulsifiers such as oxyalkylenated (more particularly polyoxyethylene) fatty acid esters of glycerol; oxyalkylenated fatty acid esters of sorbitan; oxyalkylenated (oxyethylenated and/or oxypropylene) fatty acid esters; oxyalkylenated (oxyethylenated and/or oxypropylene) fatty alcohol ethers; sugar esters such as sucrose stearate; and their mixtures.

These compounds can be isolated from natural sources, prepared by synthetic means, or mixtures thereof. Tocotrienol-enriched vitamin E preparations can be obtained by fractionating vitamin E preparations to remove a portion of tocopherols and recover a more highly concentrated tocotrienol preparation. Useful tocotrienols are natural products isolated, for example, from wheat germ oil, cereal oil, or palm oil using high performance liquid chromatography, or isolated by alcohol extraction and/or molecular distillation at from barley, spent grains or oats. As used herein, the term "tocotrienols" includes tocotrienol-rich fractions obtained from these natural products as well as pure compounds. The increased activity of glutathione peroxidase protects the skin against oxidative damage.

In addition, carotenoids, particularly of the xanthophyll type, are also useful antioxidants that can be used.

Mattifying agents (also referred to as “mattifying fillers”) refer to a material that gives the complexion more transparency and a veiled effect and gives the skin a natural and desirable appearance, without giving a greasy, sparkling and shiny appearance. To do this, these materials are often absorbent fillers such as talc, silica, kaolin, or fillers having optical light scattering properties, which properties are known as the “artistic blur” effect. In addition to reducing shine or oiliness, matting agents can contribute to the overall texture and thickness of a cosmetic composition. Mattifying agents are often (but not always) particulate matter or powders.

Cosmetic compositions containing matting agents can be characterized using the following protocol. The test composition is spread at a rate of 2 mg/cm ² on a contrast card (Prufkarte 24/5-250 cm ² type sold by the company Erichsen) using a mechanical film spreader. The composition is then dried overnight at a temperature of 37° C. before measuring its reflection using a gonioreflectometer sold by the company Micromodule. The intensity specularly reflected at 30° (R) and scattered at 90° (D) is measured successively. The result obtained is the ratio R between the specular reflection and the diffuse reflection. The value of R is proportionally smaller the greater the matting effect authorized by the filler. An R value of 2 or less generally indicates a mattifying effect. Mattifying agents according to the present disclosure include those which, preferably at a content of 5% in a cosmetic composition, give an R value of less than 1.5 and preferably less than 1.

The total amount of water in the cosmetic composition can vary, but is typically about 50 to about 95% by weight, based on the total weight of the cosmetic composition. In some cases, the total amount of water is about 50 to about 90% by weight, about 50 to about 85% by weight, about 50 to about 80% by weight; about 55 to about 95 wt%, about 55 to about 90 wt%, about 55 to about 85 wt%, about 55 to about 80 wt%; about 60 to about 95 wt%, about 60 to about 90 wt%, about 60 to about 85 wt%, about 60 to about 80 wt%; about 65 to about 95 wt%, about 65 to about 90 wt%, about 65 to about 85 wt%, or about 65 to about 80 wt%; about 70 to about 95 wt%, about 70 to about 90 wt%, about 70 to about 85 wt%, about 70 to about 80 wt%, inclusive ranges and subranges, based on total weight of the cosmetic composition.

Production processes

The present disclosure also relates to methods or processes for making/manufacturing the cosmetic compositions described herein. It also includes the products prepared by these methods or processes. Typically, a process for making certain embodiments of the cosmetic compositions of the present disclosure includes forming an oil phase and forming a separate aqueous phase (containing water), the two phases being heated and combined hot. Each phase can be heated to the same temperature or each of them can be heated to different temperatures.

Thickening agents can be added to the aqueous phase of cosmetic compositions. In some cases, however, the one or more emulsifiers and/or thickening agents are added to the oil phase. Additionally or alternatively, thickening agents can be added post-emulsification — for example, ammonium polyacryloyldimethyl taurate can be added post-emulsification.

After combining the oil phase and the aqueous phase to form an emulsion, the composition is typically allowed to cool. Additional components can be added during the emulsification period or afterwards. For example, certain perfumes, coloring agents, exfoliants, active ingredients, etc., can be added to the aqueous phase, to the fatty phase, or after emulsification.

Methods of use

The present disclosure also relates to methods of using the cosmetic compositions described herein. For example, the cosmetic compositions can be used in a method that includes applying the cosmetic compositions to the skin of humans. In some cases, the composition is applied to the face. Additionally, the cosmetic composition can be used in methods of treating and/or repairing damage to the skin (eg, damage due to photoaging), and to diminish the appearance of wrinkles, dark spots, and uneven texture skin. The aforementioned methods are non-therapeutic.

The cosmetic composition can be applied once a day, twice a day, or more than once or twice a day. In some cases, the composition is applied in the evening before bedtime. In other cases, the compositions are applied in the morning. In still other cases, the composition can be applied immediately after washing the skin. The compositions can be used once, or for a series of days, weeks, or months. For example, the compositions can be used daily for a period of 1, 2, 3, 4, 5, 6, 7, 8 or more weeks, or months.

All components and elements positively presented in the present disclosure can be negatively excluded from the claims. In other words, the cosmetic compositions of this disclosure may be free or substantially free of all components and elements positively cited throughout this disclosure.

In some instances, the cosmetic compositions of the present disclosure may be substantially free of non-incidental amounts of the ingredient(s) or compound(s) described herein. A non-accessory quantity of an ingredient or compound is the quantity of this ingredient or compound which is added to the cosmetic composition itself. For example, a cosmetic 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 which is included as a mixture of two or more compounds.

Some of the various component categories identified may overlap. In such cases where an overlap may exist and the composition includes both components (or the composition includes more than two overlapping components), an overlapping compound does not represent more than one component. For example, tocopherol can be characterized as both a skin active agent and a preservative. If a particular composition includes both a skin active agent and a preservative, tocopherol will serve only as a skin active agent or only as a preservative (tocopherol does not serve as both a skin active agent and a preservative). conservative).
