DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to cosmetic compositions and more particularly, to pigmented foundation make-up compositions and concealers.
BACKGROUND OF THE INVENTION
A foundation composition can be applied to the face and other parts of the body to even skin tone and texture and to hide pores, imperfections, fine lines and the like. A foundation composition is also applied to moisturize the skin, to balance the oil level of the skin and to provide protection against the adverse effects of sunlight, wind and the harsh environment. Make-up compositions are generally available in the form of liquid or cream suspensions, emulsions, gels, pressed powders or anhydrous oil and wax compositions. Such cosmetic make-up compositions are described in U.S. Pat. No. 3,444,291, U.S. Pat. No. 4,486,405, U.S. Pat. No. 4,804,532, U.S. Pat. No. 3,978,207, U.S. Pat. No. 4,659,562, U.S. Pat. No. 5,143,722 and Nakamura et al., Preprints of the XIVth I.F.S.C.C. Congress, Barcelona, 1986, Vol. I, 51-63 (1986).
Foundations in the form of water-in-oil emulsions are well known and provide good coverage and good skin feel, wear and appearance. It is also important for water-in-oil foundation compositions to provide oil and shine control which effects the appearance of the skin. Persons with an oily skin type or combined skin type typically manifest an oily and/or shiny appearance between cleansings. The oily or shiny appearance generally increases as the day progresses following cleansing of the skin. In order to avoid such appearance, individuals must throughout the day either cleanse the skin, blot the skin, apply oil absorbing powders to the skin, or take some other measure to minimize the appearance of oil or shine.
An oily or combination skin type presents a particular challenge to the formulation of make-up intended for facial use, including foundations. This is because as oil accummulates on the facial skin of such individuals, oil breakthrough occurs (the oil is not masked by the make-up such that an oily or shiny skin appearance results), and the covarage and wear resistance of the make-up tends to be reduced. Attempts have been made to provide foundations which balance the oil level of the skin. Clays, talcs, silicas, starches, polymers, and other similar materials have been suggested for use in cosmetic compositions for absorbing sebum and controlling oily skin. However, many compositions known in the art either provide benefits that are very limited, in terms of degree of efficacy, duration of efficacy, or both. Therefore, it would be desirable to provide a foundation composition having even greater oil/shine control and improved skin appearance.
Some amino acid salts of salicylic acid have been found to be of use in pharmaceutical compositions. For example, arginine salicylate is an arginine salt of salicylic acid which can be prepared in situ by reacting an alcoholic solution of salicylic acid or suitable salicylic acid derivative with an alcoholic suspension of arginine. Processes of preparing arginine salicylate are described in ES-A-513383 and FR-6838M. FR-6836M discloses the use of arginine salicylate in pharmaceutical compositions for oral, rectal and parenteral administration in the treatment of arthiritis and inflammation. Lysine salicylate has also been disclosed for use in analgesic compositions for oral and injectable administration, see for example SK-A-9203565 and CS-A-9103692. However, these documents do not disclose use of amino acid salts of salicylic acid for providing oil control in topical cosmetic compositions.
It has now surprisingly been found that by incorporating an amino acid salt of salicylic acid or salicylic acid derivative into a water-in-oil emulsion a cosmetic composition is provided which exhibits improved oil and/or shine control and improved skin appearance.
Since arginine salicylate is known to have anti-inflammatory properties, the compositions of the present invention also provide anti-inflammatory activity.
It is accordingly an object of the present invent
