Abstract

Cosmetic lipstick containing a combination of
a) Sodium Saccharin (INCI: Sodium Saccharin) and
b) Citric acid (INCI: Citric Acid).

Description

The present invention relates to a cosmetic lipstick containing a combination of sodium saccharin (INCI: Sodium Saccharin) and citric acid (INCI: Citric Acid).

The desire to look beautiful and attractive has been rooted in people for thousands of years. Even though the ideal of beauty has changed over time, the pursuit of a flawless appearance has always been people's goal, as a pleasant appearance increases their self-esteem and attractiveness to others.

The term decorative cosmetics comes from the Latin “decoratio” - highlighting what is beautiful. Usually, individual parts of the body, especially the face, are highlighted with the help of dyes and color inconsistencies are softened.

In addition to face powders and rouge as powdered cosmetics and stick-shaped preparations, cream-like preparations such as day creams and emulsion-based cream make-up are also used.

Lipstick is one of the most commonly used decorative cosmetics. More than 50% of women in Germany use it. In addition to adding color to the lips, it is also often used for lip care.

Lipsticks usually consist of a wax matrix into which liquid and semi-solid oils, pigments and fillers are incorporated in high concentrations. They come in solid stick form.

Lipsticks are subject to particularly high standards in terms of their safety, as it cannot be ruled out that parts of the preparation may come into contact with the mouth and/or be swallowed during use and wear. Since individual ingredients in lipsticks have an unpleasant taste, it is also important to mask this taste in order to make the lipstick more attractive to consumers. Sweeteners are often used for this purpose. Potential sweeteners that could be used include sodium saccharin (INCI: Sodium Saccharin) and/or neohesperidin dihydrochalcone (INCI: Neohesperidin Dihydrochalcone).

A disadvantage of the current state of the art, however, is the fact that lipsticks with sodium saccharin tend to discolor yellow ("yellow tinge"). Preparations with a combination of sodium saccharin and neohesperidin dihydrochalcone tend to discolor red or even brown. This effect occurs particularly at higher temperatures and longer storage times. If there are (unplanned) delays in production during the warm phase or if a lipstick is stored at a higher temperature (e.g. in summer), this can lead to undesirable discoloration of the product. During the production process, the preparation may have to be completely discarded and disposed of at great expense.

It was therefore the object of the present invention to develop sweetener-containing lipstick formulations (in particular those with sodium saccharin and/or neohesperidin dihydrochalcone) which are color-stable even at higher temperatures and over longer storage periods.

Lipstick preparations often contain one or more color pigments, as they usually serve to color the skin of the lips.

A disadvantage of the current state of the art is the fact that the combination of sweetener (particularly sodium saccharin and neohesperidin dihydrochalcone) and pigments leads to the preparations becoming inhomogeneous. Even during production, it is noticeable that in formulations containing sweeteners, the pigments are no longer distributed evenly in the hot, liquid stick mass, but sink to the bottom. This means that sticks with a uniform composition can no longer be cast from this liquid stick mass.

It was therefore the object of the present invention to develop a lipstick formulation containing color pigments and sweeteners in which the color pigments can be homogeneously incorporated into the preparation.

The Lab values of examples 16-21 show that as the concentration of citric acid increases, the a and b values decrease steadily, causing the color to change to the blue-green range. The resulting color is optically preferable compared to the original color without citric acid.
