The present invention is related to anhydrous cosmetic compositions having enhanced anti-oiliness properties, dry touch to the skin after the application combined with mate effect, and with a very light, thin and invisible touch on the skin, comprising A) an emollient system, B) a filler system, and C) an UV filter. The present invention is also directed to a process of manufacturing the anhydrous cosmetic compositions and their uses as a sunscreen daily product and for reducing the oiliness of the skin.

FIELD OF THE INVENTION

The present disclosure is directed to high SPF anhydrous cosmetic compositions. More specifically, the present disclosure is directed to high SPF anhydrous cosmetic compositions in a stick format having enhanced anti-oiliness properties, dry touch to the skin after the application combined with mate effect, and with a very light, thin and invisible touch on the skin, wherein the anhydrous cosmetic compositions comprising A) an emollient system, B) a filler system, and C) an UV filter system. The present invention is also directed to a process of manufacturing the anhydrous cosmetic compositions and their uses as a cosmetic sunscreen daily product and for reducing the oiliness of the skin.

BACKGROUND OF THE INVENTION

The photoprotection of keratinous materials, including both skin and hair, is considered of great importance in order to protect from sun-damage, sunburn, photo-aging, as well as to decrease the chances of skin cancer development caused by exposure to ultraviolet (“UV”) radiation. There are typically two types of UVA/UVB cosmetic sunscreen compositions used to accomplish photoprotection, namely, inorganic UV filters and organic UV filters.

The degree of UV protection afforded by a cosmetic sunscreen composition is directly related to the amount and type of UV filters contained therein. The higher the amount of UV filters, the greater the degree of UV protection (UVA/UVB). Particularly, cosmetic sunscreen compositions must provide good protection against the sun, a measure of which is the Sun Protection Factor (SPF) value, yet have satisfactory sensory perception, such as a smooth but not greasy feel upon application.

Usually, cosmetic sunscreen products may be in the form of lotions, milks, creams, gels, gel creams, foams, sprays and sticks. Such products can be anhydrous or in the form of emulsions, generally containing cosmetic sunscreen actives that are solubilized, emulsified, or dispersed in a vehicle, which is topically applied onto the skin. The cosmetic sunscreen actives, typically through the aid of polymers and other ingredients included in the vehicle, form a thin, protective, and often water-resistant layer on the skin.

Hydrophobic silica is commonly known in the cosmetic industry for providing anti-oiliness and anti-acne effects, including in cosmetic sunscreen compositions. However, the maximum concentration of silica in a composition is limited, due to its high hydrophobic properties, thereby rendering the composition instable when high concentrations of silica are applied. In this sense, cosmetic sunscreen compositions are usually limited to have about 0.5% by weight of silica, relative to the total weight of the composition.

Thus, there has been a need for cosmetic sunscreen compositions having higher concentrations of silica, to enhance the anti-oiliness, dry touch and matte effect thereof. The challenge of incorporating high concentrations of silica in the cosmetic sunscreen composition is not only limited due to the hydrophobic nature of the silica, but there is also the challenge on formulating stable compositions while preserving satisfactory properties of the product, such as hardness, high SPF and dry touch to the skin after application combined with matt effect.

Considering the current drawbacks of the state of the art and the difficulties to overcome them, the inventors formulated an anhydrous cosmetic composition that enables the high concentration of hydrophobic silica by combining an emollient system, a filler system and an UV filter system. The anhydrous cosmetic compositions of the present invention having high concentration of silica surprisingly showed enhanced anti-oiliness effect, high SPF values, dry touch to the skin after application combined with matte effect, and with a very light, thin and invisible touch on the skin.

SUMMARY OF THE INVENTION

The present invention is directed to anhydrous cosmetic compositions having enhanced anti-oiliness effect, high SPF values, dry touch to the skin after application combined with matte effect, and with a very light, thin and invisible touch on the skin, comprising an emollient system, a filler system and an UV filter system. The present disclosure is also directed to a process of manufacturing the anhydrous cosmetic compositions and uses of the anhydrous cosmetic compositions.

Particularly, the present invention relates to the use of the cosmetic composition for the manufacture of a product to be used as a sunscreen daily product and for reducing the oiliness of the skin.

The inorganic UV filter used for the present invention may be active in the UV-A and/or UV-B region. The inorganic UV filter may be hydrophilic and/or lipophilic. The inorganic UV filter is in some embodiments insoluble in solvents, such as water, and ethanol commonly used in cosmetics.

It is in some embodiments desirable that the inorganic UV filter be in the form of a fine particle such that the mean (primary) particle diameter thereof ranges from about 1 nm to about 50 nm, and in some embodiments from about 5 nm to about 40 nm, and in some embodiments from about 10 nm to about 30 nm. The mean (primary) particle size or mean (primary) particle diameter here is an arithmetic mean diameter.

The inorganic UV filter can be selected from the group consisting of silicon carbide, metal oxides which may or may not be coated, and mixtures thereof. And in some embodiments, the inorganic UV filters are selected from pigments (mean size of the primary particles: generally from about 5 nm to about 50 nm, and in some embodiments from about 10 nm to about 50 nm) formed of metal oxides, such as, for example, pigments formed of titanium oxide (amorphous or crystalline in the rutile and/or anatase form), iron oxide, zinc oxide, zirconium oxide, or cerium oxide, which are all UV photoprotective agents that are well known per se.

SPF and Water Resistance Evaluation

The composition according to Example 1 was submitted to a SPF and a Water Resistance evaluation. The tests were performed following the ISO/EN 24444 Cosmetics Sun protection test-in vivo determination of the Sun Protection Factor (SPF) (2010). The Water resistance evaluation was performed according to the Colipa Guidelines (December 2005). The results are summarized in table 1 below.

It can be seen from the tests performed that example 1 according to the present invention shown high mean SPF value and good water-resistance property.

Product Performance Evaluation

The objective of this study was to assess and compare the effect on sebum and shininess control of the anhydrous cosmetic composition according to Example 1 vs bare skin until 2 hours of exposure in Hammam room conditions (37±1° C./60±5% RH).

The volunteers arrived without product in the face and stayed in controlled environment for 20 min (21° C.±1; 45%±5 RH) before the first measurements (T0—baseline values), when sebum and shininess levels were evaluated using the equipment's Sebumeter and LightCam and standardized VISIA pictures were taken.

After that, the anhydrous cosmetic composition of Example 1 was randomly applied on half face by the investigator. The volunteers stayed in controlled environment for 10 min (21° C.±1; 45%±5 RH).

Thereafter, sebum and shininess levels were evaluated (T10 min) and new pictures were taken. After 2 h in Hammam room conditions (T2H) the measurements were repeated: shininess and sebum levels were evaluated, and also VISIA pictures.

The anhydrous cosmetic composition of Example 1 showed significant sebum and shine reduction and control ability (i.e., anti-oiliness properties). Also, the anhydrous cosmetic composition of Example 1 showed statistically significant differences compared to the untreated skin considering sebum and shininess 10 minutes after the application and also after 2 hours of exposure to Hammam room with the side treated with the composition of Example 1 presenting the lowest values.

The anhydrous cosmetic composition according to Example 1 significantly reduced the sebum casual level 10 minutes after the application (p=0.000). After 2 hours in Hammam room sebum casual level remained significantly lower compared to the baseline (p=0.000) and did not statistically change in comparison to T10 min (p=0.110).

Sebum casual level for the bare skin remained constant 10 minutes after application (T10 min) (p=0.523). After 2 hours in Hammam room there was a significant increase in comparison to T10 min (p=0.005), and the sebum reestablished its initial condition (p=0.068).

The anhydrous cosmetic composition according to Example 1 showed statistically significant differences compared to the untreated bare skin considering sebum casual level 10 minutes after the application (p=0.000) and also after 2 hours of exposure to Hammam room (p=0.000), presenting significant lower values in both times of assessment.

The anhydrous cosmetic composition according to Example 1 significantly reduced the shininess 10 minutes after the application compared to the baseline condition (p=0.010). After 2 hours in Hammam room the increase of shininess was not significant compared to T10 min (p=0.149) and also in comparison to the baseline condition (p=0.595).

Shininess for the untreated skin increased 10 minutes after application (T10 min) (p=0.000). After 2 hours in Hammam room there was a significant increase was observed compared to T10 min (p=0.000) and also compared to the baseline condition (T0) (p=0.002).

The anhydrous cosmetic composition according to Example 1 and the untreated skin showed statistically significant differences between them considering shininess level 10 minutes after the application (p=0.000) and also after 2 hours of exposure to Hammam room (p=0.000), with the side treated by The anhydrous cosmetic composition according to Example 1 presenting lower values.

In comparison to the bare skin, the anhydrous cosmetic composition according to Example 1 was able to reduce shininess 22.69% 10 minutes after application and 29.50% after 2 hours in Hammam room conditions.

Product Performance Evaluation in Comparison with Conventional Products

After the evaluation of the texture, it was observed that the conventional product is more slippery and easier to distribute, however, it crumbles a little on the edges of the stick and has a more waxy touch at the end of the application on the skin. Also, the conventional product leaves a slight blurry look, and it was easy to observe where the product was applied (undesired effect).

Unlike the conventional product of the prior, the anhydrous cosmetic composition of the present invention has more resistance when sliding the stick through the skin and it is difficult to perceive the product being transferred from the bullet to the skin, as the texture is transparent and dull (matte effect), which makes it difficult to perceive the product being transferred from the stick to the skin (desired effect).

In conclusion, the anhydrous cosmetic composition of the present invention, according to Example 1, is less slippery, less silicone and less waxy than the conventional product of the prior art, as well as the anhydrous cosmetic composition of the present invention leaves a transparent film, whereas the conventional product of the prior art leaves a white film.

Regarding the immediate effect, the product of the present invention is drier and has a matte effect. After the return of 4 hours after the application of the product on the skin, the product of the present resulted in more dry touch (medium amount of attribute), touch with light waxy residual and slightly soft. Concerning the visual effect, the matte effect was preserved.

Unlike the present invention, the conventional product of the prior art left the touch slightly sticky, the fingers lock when sliding on the surface of the skin and has a waxy residue—with a lot of presence of this attribute.

In other words, the anhydrous cosmetic composition of the present invention having enhanced anti-oiliness properties, dry touch to the skin after the application combined with mate effect, and with a very light, thin and invisible touch on the skin.
