Description

Two-phase sunscreen composition

Technical Field

The present invention relates to a sunscreen composition for keratin materials such as the skin, in particular a sunscreen cosmetic composition in biphasic form.

Background

For sunscreen products, good UV protection is one of the key functions. In addition, to meet consumer preferences, it is preferred that sunscreen products provide good texture.

Biphasic compositions comprising an aqueous phase and an oil phase have benefits in their usability due to their low viscosity. In addition, they have another benefit in their appearance because they do not exhibit a whitish appearance as do emulsion compositions.

There remains a need for a dual phase form of sunscreen composition having better UV protection properties and providing good texture.

Best mode for carrying out the invention

As a result of diligent research, the inventors have found that a biphasic composition comprising an aqueous phase and an oil phase comprising at least one organic UV filter, at least one first polyglyceryl fatty acid ester having an HLB value of greater than 8, at least one second polyglyceryl fatty acid ester having an HLB value of 8 or less, at least one powder and water can provide good UV protection properties and texture.

Thus, the composition according to the invention is a biphasic composition comprising an aqueous phase and an oil phase, wherein the composition comprises:

(a) at least one organic UV filter,

(d) at least one powder, and

(e) and (3) water.

Hereinafter, the composition according to the present invention will be explained in a more detailed manner.

[ composition ]

The composition according to the invention may be a cosmetic composition, and is preferably a cosmetic composition for keratin materials such as the skin. The composition according to the invention may be intended for use as a topical cosmetic composition. Thus, the composition according to the invention may be intended for application to keratin materials. The keratin substance herein means a material containing keratin as a main constituent element, and examples thereof include skin, scalp, nails, lips, hair, and the like. In particular, the composition according to the invention may be a skin sunscreen cosmetic composition for protecting the skin from ultraviolet rays.

The composition according to the invention has a biphasic form comprising an aqueous phase (aqueous or water phase) and an oil phase, or an oil phase and a water-in-oil emulsion phase, such as a water-in-oil pickering emulsion phase. By biphasic composition according to the invention is meant a composition comprising or consisting of two phases, an aqueous phase and an oil phase or an oil phase and an emulsion phase, which are visually and/or macroscopically separate at rest.

The term "aqueous phase" means here a phase which is liquid at room temperature and which comprises or consists of hydrophilic, water-soluble or water-dispersible substances.

The term "oily phase" means here a phase which is liquid at room temperature and which comprises or consists of lipophilic, oil-soluble or oil-dispersible substances.

The term "water-in-oil emulsion phase" means herein the phase which is liquid at room temperature comprising the dispersed aqueous phase in the oil phase.

The biphasic composition according to the invention has visually two distinct layers at rest, each layer consisting of a continuous aqueous phase and a continuous oil phase or a continuous oil phase and a water-in-oil emulsion phase, respectively.

The oil phase of the invention preferably has a viscosity at room temperature (25 ℃) of less than 1000 mPa ∙ s, preferably less than 300 mPa ∙ s, and more preferably less than 100 mPa ∙ s. The lower limit of the viscosity of the oil phase is not limited, but in general, the oil phase has a viscosity of more than 5 mPa ∙ s at room temperature.

The viscosity of the aqueous phase of the present invention is not particularly limited. Preferably, the viscosity of the aqueous phase may be in the range of from 15 to 40 mPa ∙ s, more preferably from 17 to 30 mPa ∙ s, at room temperature.

For viscosity measurement, VISCOMAN ™ (GILSON Technology) can be used. Bulk viscosity (mPaS, PaS) was automatically calculated from the required suction in a small pipette (10 μ Ι _ in).

The composition according to the invention is intended to be used after each phase has been homogeneously mixed, for example by simply shaking it. Since the homogeneous composition of the present invention has a relatively lower viscosity after mixing, especially a lower viscosity than the emulsion composition, the present invention is advantageous in that it can be easily sprayed in a mist state without using an aerosol device and can be easily spread on keratin materials. Thus, the composition according to the invention may be contained in a non-aerosol device, such as a container, spray bottle or pump bottle equipped with a mist generating means, such as a mist pump.

The pH of the aqueous phase of the present invention is not particularly limited. The pH of the aqueous phase may be in the range of 3.0 to 9.0, and preferably 4.0 to 8.0. The pH of the aqueous phase of the present invention can be adjusted to a desired value using acidifying, basifying or buffering agents commonly used in the cosmetic field.

The inventors of the present invention have surprisingly found that the mixed composition according to the invention forms a uniform and fine film on keratin materials such as the skin, in particular when applied as a mist. Thus, the composition can provide improved UV protection. In addition, because the composition according to the invention can be provided in the form of a mist, it allows easy touch-up use by the consumer when needed, even after the sunscreen product has been applied once. In addition, the mist product of the present invention can be easily applied to makeup (make-up). In addition, the mist product of the present invention can provide a comfortable texture to the consumer, which is quite different from aerosol spray type products.

In a preferred embodiment of the invention, the composition according to the invention comprises a larger amount of aqueous phase than oil phase. In another preferred embodiment of the present invention, the weight ratio of aqueous phase/oil phase may be 1 or higher, preferably 1.5 or higher, more preferably 2 or higher, and even more preferably 2.5 or higher.

The amount of the aqueous phase in the composition according to the present invention may be 50 wt% or more, preferably 60 wt% or more, and more preferably 70 wt% or more, and may be 90 wt% or less, preferably 85 wt% or less, and more preferably 80 wt% or less, relative to the total weight of the composition.

The amount of the oil phase in the composition according to the present invention may be 5% by weight or more, preferably 10% by weight or more, and more preferably 15% by weight or more, and may be 50% by weight or less, preferably 40% by weight or less, and more preferably 30% by weight or less, relative to the total weight of the composition.

The composition according to the invention comprises (a) at least one organic UV filter, (b) at least one first polyglyceryl fatty acid ester having an HLB value of greater than 8, (c) at least one second polyglyceryl fatty acid ester having an HLB value of 8 or less, (d) at least one powder and (e) water.

Examples

The present invention will be described in more detail through examples. However, these examples should not be construed as limiting the scope of the invention.

[ composition ]

Each composition according to examples 1 to 9 (example 1 to example 9) and comparative examples 1 to 4 (comparative example 1 to comparative example 4) was prepared by mixing the ingredients shown in tables 1 and 2 below. The compositions are shown in tables 1 and 2. The numerical values of the amounts of the ingredients are all based on "wt%" of the active material.

[ evaluation ]

(film uniformity)

Each composition was shaken 10 times in a closed container to become uniform. Each homogeneous composition was applied to a polypropylene sheet (thickness 0.2 mm, PX-P from Sekisui Kagaku) using an applicator known as "Elecometer 4340" using a force of 1 kgf, so as to obtain a 10 μm coating of the composition on the sheet. Then, the sheet was exposed to an ultraviolet lamp (UV black rays B-100AP, wavelength 365 nm) and photographed. Film uniformity was evaluated in three grades ("+ +", "+" and "-") based on the visual appearance of the coated sheet. If the appearance is uniformly strong black, it is listed as "+". If the appearance is non-uniform blue translucency, it is listed as "-".

(in vitro SPF and PPD values)

Each composition was shaken 10 times in a closed container for homogenization. Using an adjustable pipette at 0.8 mg/cm²Amounts each homogeneous composition was transferred to a plate (Helio plate HD 6, PMMA, roughness 6 μm) and then uniformly smeared with a finger. The coated panels were allowed to air dry at room temperature for 15 minutes. The resulting sample plate was placed in a Labsphere ultraviolet transmittance analyzer (model UV-2000, from Solar Light Company, Philadelphia, Pa.). The illumination was performed at 12 points on the sample plate.

In vitro SPF values were predicted from the absorbance intensity in the UV-B range (290 nm-320 nm). Higher absorption intensity indicates higher in vitro SPF values. In vitro SPF values were calculated by Labsphere using the COLIPA method.

In vitro PPD values were predicted from the absorbance intensity in the UV-A range (320 nm-380 nm). Higher absorption intensity indicates higher in vitro PPD values. The in vitro PPD value was calculated according to a method adopted by the Japan Cosmetic Industry Association (JCIA) as an official test procedure for UV-A labeling of products, which is commonly used in European and American test laboratories (Japanese Cosmetic Industry Association Technical Bulletin), a Measurement standard for UVA protective efficacy (Measurement Standards for UVA protection efficacy), issued on 21.11.1995 and validated from 1.1.1996).

(texture)

Texture was assessed using trained professional protocols. Each composition was shaken 10 times in an APTAR SP22 PANACHE insertion pump for homogenization and then applied as a fog by a professional operator in controlled gestures and amounts (2 pushes) on the panelist's facial skin (n = 6). Texture was evaluated with the following standards:

good: which provides a very light and non-greasy texture,

difference: it provides a greasy texture.

The evaluation results are summarized in tables 1 and 2 below.

TABLE 1

TABLE 2

As can be seen from tables 1 and 2, the compositions according to each of examples 1 to 9 comprising the specific combination of ingredients (a) to (e) of the present invention exhibit good film uniformity and high in vitro SPF and/or PPD values. In addition, they provide a fresh texture, which is preferred by consumers.

On the other hand, each of the composition according to comparative example 1 (which lacks the first polyglyceryl fatty acid ester), the composition according to comparative example 2 (which lacks the second polyglyceryl fatty acid ester), and the composition according to comparative example 3 (which lacks the powder) exhibited poor film uniformity. In addition, the composition according to comparative example 4, which included poly C10-30 alkyl acrylate instead of the powder of comparative example 3, provided a greasy texture.

Thus, it can be concluded that: the composition according to the invention is very preferred as a sunscreen composition because it provides improved UV protection (due to high in vitro SPF and/or PPD values) and good texture. In addition, because the homogeneous blend composition of the present invention has a relatively low viscosity, it can be easily applied to keratin materials and can be very suitable for consumers.
