Embodiment I

[0198] Embodiment 1: lipstick preparation

[0199] Lipstick compositions (% by weight) of the following formulations were prepared:

[0200] Table 1

[0201]

[0202]

[0203] step:

[0204] Pre-grind the pigment in a part of the oily ingredients. Then, the polymer or wax structural component and the remaining oily components are melted separately, and the matting agent and other fillers are added under continuous stirring, and then the ground pigment is added to the previous mixture. Finally, suitable active substances or fragrances can be added. Then, hot cast into molds. Then, demolding is performed after cooling.

Embodiment II

[0205] Example II: Specific Surface Area Measurement of Matting Fillers

[0206] Specific surface area measurements of matting fillers can be performed using the BET tristar II measuring device. The method is based on the adsorption of nitrogen molecules on the surface and pores of powder samples at low temperature (nitrogen liquefaction temperature: 77°K). Specific surface area in m 2 / g means.

[0207] Table 2

[0208]

Embodiment III

[0209] Example III: Gloss and Hardness Measurements

[0210] Gloss measurement

[0211] Using an automatic applicator, apply the lipstick composition from each example prepared in Example 1 on a white background comparison chart with a thickness of 500 nm, using the name micro-TRI-gloss or PICOGLOSS 503 sold by the company BYK The gloss meter measures the gloss value at 85°.

[0212] Gloss values ​​are obtained as the mean of 3 measurements at three different points of the comparison chart and are given in Table 3.

[0213] Hardness measurement

[0214] The hardness of the composition expressed in grams (g) is determined by measuring the compressive strength at 20°C using a texture measuring instrument sold by the Swantech society under the name "TA-XT Plus Microstable System". The texture analyzer was equipped with a stainless steel cylinder with a diameter of 2 mm, which moved at a speed of 1 mm / s and was inserted into the composition to a depth of 3 mm.

Abstract

The invention relates to a matte lipstick composition, comprising at least one structure-directing agent, at least one oil, at least one colouring agent, and at least one particular filler as a mattifying agent, characterised in that the particular filler serving as a mattifying agent is selected from among particles having a specific surface area of less than 30 m2 / g, preferably less than 20 m2 / g, more preferably still less than 10 m2 / g, and advantageously less than 5 m2 / g. The invention also relates to a lipstick comprising the lipstick composition, a method for producing said lipstick composition, and the use of a particular filler in order to mattify a lipstick composition without hardening same.

Description

technical field [0001] The present invention relates to the field of cosmetics, more particularly to matte and colour-intense solid cosmetic compositions, such as matte and colour-intense lipsticks. Background technique [0002] The use of lipstick as a means of coloring the lips has undergone rapid development, so lipstick is now a widespread beauty product. A cosmetically acceptable lipstick should be easy to spread, uniform in color, and have a melting point above body temperature. In addition, it should give the lips a smooth but non-greasy appearance and should maintain its consistency without oozing, spilling, cracking or disintegrating. [0003] A lip balm should not only have the above characteristics, but above all should give the lips a smooth and creamy feel and protect them from dryness or chapping. Such a smooth and creamy feel is particularly difficult to achieve with lipsticks that have reduced luminosity or gloss (ie, matte appearance). [0004] Typically,...
