Description

DESCRIPTION

BI-PHASE SUN CARE COMPOSITION TECHNICAL FIELD

The present invention relates to a sun care composition, in particular a sun care cosmetic composition in a bi-phase form, for a keratinous substance such as skin.

BACKGROUND ART

For sun care products, good UV protecting effects and good usability are among the key functions. In addition, in order to satisfy consumers’ preferences, it is preferable that sun care products show a clear appearance.

Bi-phase compositions comprising an aqueous phase and an oily phase have a benefit regarding their usability thanks to their low viscosity. In addition, they have another benefit regarding their appearance since they do not show a whitish appearance as emulsion compositions do.

To date, some prior art documents exist relating to sun care compositions having the bi-phase form. For example, JP-A-2015- 199689 discloses a composition separated into two phases and containing (A) an oil soluble ultraviolet absorber, (B) a water soluble polymer thickener; and (C) a nonionic surfactant, which can be easily mixed homogenously at the time of use and can be sprayed in a misty state. In addition, JP-A-2002-193742 discloses a double layered liquid cosmetic wherein powder is floating in an interface between an upper phase and lower phase.

However, there is still a need for sun care compositions in the bi-phase form having a better UV protection property and mist-forming quality.

BEST MODE FOR CARRYING OUT THE INVENTION

After diligent research, the inventors have discovered that a bi-phase composition of an aqueous phase and an oily phase, comprising at least one solid organic UV-B filter, at least one liquid organic UV-B filter, and at least one powder can provide a good UV protecting property and mist-forming quality.

Thus, the composition according to the present invention is a bi-phase composition comprising an aqueous phase and an oily phase, wherein the composition comprises:

(a) at least one solid organic UV-B filter,

(b) at least one liquid organic UV-B filter, - -

(c) at least one powder, and

(d) water.

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

[Composition]

The composition according to the present invention may be intended for use as a cosmetic topical composition. Thus, the composition according to the present invention may be intended for application onto a keratinous substance. Keratinous substance here means a material containing keratin as a main constituent element, and examples thereof include the skin, scalp, nails, lips, hair, and the like. In particular, the composition according to the present invention may be a skin sun care cosmetic composition for protecting skin from UV rays.

The composition according to the present invention has a bi-phase form comprising an aqueous phase and an oily phase, or an oily phase and a water in oil emulsion phase, preferably water in oil pickering emulsion phase.

The bi-phase composition according to the present invention means a composition comprising or consisting of two phases of an aqueous phase and an oily phase or the oily phase and the emulsion phase, which are visually and/or macroscopically separated at rest.

The term“aqueous phase” here means a phase that is liquid at room temperature, comprising or consisting of hydrophilic, water-soluble, or water-dispersible substances.

The term“oily phase” here means a phase that is liquid at room temperature, comprising or consisting of lipophilic, oil-soluble, or oil-dispersible substances. The term“water in oil emulsion phase” here means a phase that is liquid at room temperature, comprising dispersed aqueous phases in an oily phase.

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

The oily phase of the present invention preferably has a viscosity of less than 1000 mPa-s, preferably less than 300 mPa-s, more preferable less than 100 mPa-s at room temperature (25°C). The lower limit of the viscosity of the oily phase is not limited, but in general, the oily phase has a viscosity of more than 5mPa-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 can range from 15 to 40 mPa-s, more preferably from 17 to 30 mPa-s at room temperature.

For the viscosity measurement, VISCOMAN™ (GILSON Technology) can be used. The bulk viscosity (mPaS, PaS) is automatically calculated from the needed aspiration force in the small pipet (10 pL).

The composition according to the present invention is intended for use after mixing each phase homogenously, for example, by simply shaking it. Since the homogenous composition of the present invention after mixing has a relatively lower viscosity, especially a lower viscosity than an emulsion composition, the present invention has a benefit in that it can be easily sprayed in a misty state without using an aerosol device and easily spread on keratinous substances. Therefore, the composition according to the present invention may be contained in a non-aerosol device, such as a container equipped with a mist generating means, such as a mist-pump, a spray bottle, or a pump bottle.

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

The inventors of the present invention surprisingly found that the mixed composition according to the present invention, in particular applied as a mist, can form a homogenous and fine film on keratinous substances, such as skin. Accordingly, the composition can provide improved UV protecting effects. In addition, since the composition according to the present invention can be provided in a misty state, it allows consumers an easy retouch use, if necessary, even after sun-care products are once applied. Also, mist-state product of the present invention can be easily applied on make-up. Furthermore, the mist-state products of the present invention can provide a comfortable texture to consumers, which is totally different from aerosol spray-type products.

In addition, the composition according to the present invention has good stability in terms of a crystalline form. The composition according to the present invention can control the formation of a crystal in the composition even after storage.

The amount of the aqueous phase in the composition according to the present invention may range from 20 to 80% by weight, preferably from 30 to 70% by weight, and more preferably from 40 to 60% by weight, relative to the total weight of the composition.

The amount of the oily phase in the composition according to the present invention may range from 20 to 80% by weight, preferably from 30 to 70% by weight, and more preferably from 40 to 60% by weight, relative to the total weight of the composition.

EXAMPLES

The present invention will be described in a more detailed manner by way of examples.

However, these examples should not be construed as limiting the scope of the present invention.

[Compositions]

Each of the compositions according to Examples 1 to 12 (Ex. 1 to Ex. 12) and Comparative Examples 1 to 5 (Comp. Ex. 1 to Comp. Ex. 5) was prepared by mixing the ingredients shown in Tables 1 to 3. The compositions are shown in the following Tables 1 to 3. The numerical values for the amounts of the ingredients are all based on“% by weight” as active raw materials. [Evaluation]

(Film Homogeneity)

Each of the compositions was shaken 10 times in a capped container to be homogeneous.

Each of the homogenous compositions was applied to a polypropylene sheet (thickness: 0.2 mm, PX-P from Sekisui Kagaku) using an applicator called“Elecometer 4340” with a force of lkgf, so as to obtain a 10 pm coating of the composition on the sheet. The sheet was then exposed to a UY lamp (UV black ray B-100AP, wave length: 365nm) and a picture was taken. The film homogeneity was evaluated based on the visual appearance of the coated sheet in five grades (Very Good, Good, Fair, Bad, and Very Bad). If the appearance was

homogeneous intensive black, it was ranked as“Very Good”. If the appearance was non-homogenous blue translucent, it was ranked as“Very Bad”.

(SPF)

Each of the homogenous compositions was transferred onto a plate (Helio plate HD 6, PMMA, roughness: 6pm) with an adjustable pipette in an amount of 0.8 mg/cm² of the plate and then uniformly spread by the fingers. The coated plate was air dried for 15 minutes at room temperature. The obtained sample plate was placed into a Labsphere Ultraviolet Transmittance Analyzer (Model UV-2000 from Solar Light Company, Philadelphia,

Pennsylvania). Irradiation took place at 12 points on the sample plate. The in vitro SPF level was calculated by Labsphere using COLIPA method.

(Formula Structure)

Each of the compositions was shaken 10 times in a capped container to be homogeneous, and then they were left for at least 30 minutes at room temperature. The appearance of each of the compositions was observed with the naked eye to determine a formula structure.

(Mist Quality)

Each of the compositions was shaken 10 times in a spray bottle to be homogeneous. The mist quality of each of the homogeneous compositions was evaluated visually based on its sprayed droplet size and spray angle. If the sprayed droplet size was fine and the spray angle was wide, it was scored as“Good”. If the sprayed droplet size was big and the spray angle was narrow, it was scored as“Bad”. In this evaluation, ALBEA mechanical pump was used as a standard spray bottle.

(Stability)

The stability of each of the compositions was evaluated in terms of formation of crystals.

The appearances of each of the compositions was observed with the naked eye after storage for 2 months at 45 degree. If the visual bi-phase aspect didn’t change at all and no crystalline was not formed in the composition, it was evaluated as“OK”. If the visual bi-phase aspect changed or a crystalline was formed in the composition after the storage, it was evaluated as“NG”.

The evaluation results are summarized in Table 4 below. Table 1

* average particle size

Table 2

* average particle size

Table 3

* average particle size

Table 4

As can be seen from Table 4, the compositions according to each of Examples 1 to 12, which include the specific combination of the ingredients (a) to (d) of the present invention exhibited a good film homogeneity and thus a high in-vitro SPF value. In addition, they show a good mist quality and stability.

On the other hand, each of the compositions according to Comparative Examples 1 to 4, which lack the powder of the present invention, showed inferior film homogeneity and thus a low SPF value. In addition, each of the compositions according to Comparative Examples 1 to 3 did not show a good mist quality. Furthermore, the composition according to

Comparative Example 5, which lacks a solid organic UV filter, showed a low SPF value.

Therefore, it can be concluded that the composition according to the present invention can be very preferable as a sun care composition, since it has a strong UV protecting effect due to a high in vitro SPF level. In addition, since the mixed homogenous composition of the present invention has a relatively low viscosity, it can be easily applied onto keratinous substances and can be very useful for consumers.
