Description

COSMETIC COMPOSITION, PROCESS FOR MANUFACTURING THE COSMETIC

COMPOSITION AND ITS USE FIELD OF THE INVENTION

The present invention is directed to a cosmetic composition comprising

(a) a pigment system, which comprises coated pigments or/and uncoated pigments,

(b) a UV filter system, and (c) film-forming polymers, being able to not only protect the skin against the harmful effects caused by UV radiation, but also tint the skin, resulting in a color correction effect similar to a make-up foundation. The present invention is also related to a process of manufacturing the cosmetic composition and its use.

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 compositions used to accomplish photoprotection, namely, inorganic UV filters and organic UV filters.

The degree of UV protection afforded by a cosmetic 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 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.

Moreover, customers nowadays are eager for multi-purpose cosmetic compositions, which not only protect against the UV rays, but also save the need for using additional products, such as a make-up foundation, providing a covering effect such as skin color correction due to the presence of pigments.

However, many cosmetic compositions with a UV system and pigments have the drawback of transferring, after their application to the skin, to objects such as mobile phones, clothing or glasses.

Thus, there still exists a need to develop tinted cosmetic compositions that can provide sunscreen protection to the skin as well as skin color correction, resulting in an effect similar to a make-up foundation, and which do not transfer to other objects or materials after application to the skin, particularly the skin of the face. Considering the current needs of the state of the art and the difficulties to overcome them, the inventors developed a cosmetic composition with high SPF, a pigment system and film-forming polymers, which provides a tinted cosmetic composition that transfers as little as possible to other materials and objects after application to the skin, particularly the skin of the face.

SUMMARY OF THE INVENTION

The present invention is directed to a cosmetic composition comprising

(a) a pigment system, which comprises coated pigments or/and uncoated pigments,

(b) a UV filter system, and (c) film-forming polymers. The present invention is also related to a process of manufacturing the cosmetic composition and its use.

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

Consumer Test

In order to evaluate the benefices to the consumer of the present invention (Example 3), a test was performed, in which interviews were conducted with 165 women users of tinted facial sunscreen from ages 18 to 55 with oily skin and combination skin. For such interviews, the performance and customer satisfaction were evaluated after 7 days of daily application of the inventive cosmetic composition.

The results showed that around 97% of the volunteers totally agreed with the cosmetic composition of the present invention leaves the face with a uniform color right after the application and throughout the day, with a uniform color coverage. Furthermore, 99% of women totally agreed that the coverage of the present cosmetic composition is similar to the coverage expected of a makeup base/foundation.

Also, 89% of the participants totally agreed that the cosmetic composition does not transfer/dirty clothes or others, and 86% totally agreed that the cosmetic composition does not transfer/dirty cell phones.

Additional results demonstrated that the present cosmetic composition has a light texture (95% of volunteers), controlled the glow and oiliness of facial skin (around 92% of volunteers), and leaves the skin of the face with natural aspect throughout the day (94% of volunteers).

Example 12 (In vitro Test)

In order to compare non-transfer properties of cosmetic compositions with and without the ingredients (a) to (c) of the present invention, an in vitro test was performed to mimic the transfer to a smartphone scream, in which, the formulas was applied to a type of cloth and then transferred for a glass slide to be evaluated.

It was tested 3 formulas, all of them with high UV filter system, as follows:

(1 ) the first one without film former polymer(s) and with uncoated pigments (such as Example 1 );

(2) the second one with film former polymer(s) and uncoated pigments (such as Examples 4, 6, 9 and 10); and

(3) the last one with film former polymer(s) and coated pigments (such as Examples 2-3, 5, 7 and 8).

By the analysis of the results, it was concluded that the formulas (2) and (3) demonstrate a significantly superiority over formula (1 ) regarding the transferring properties.
