Problems solved by technology
However, these products are heavy, because, when applied to the lips, they are noticed, since they form a film of translucent color, without a perfect and intense covering right at the first application.
Other types of lipsticks that use mixtures with linear structural agents exhibit a non-satisfactory spreadability, and one feels the friction of the lipstick while passing it on one's lips.
As it is known, lipsticks are a complex mixture of solids, semisolids and liquids, such as waxes and emollients that, as time passes, often exudes and undergo oxidation, rendering the appearance and odor of such a product unsatisfactory.
On the other hand, lipsticks with a high concentration of emollients have the problem of flowing through the lips' edges, in addition to having low fixation power.
Many of these problems related to a poor fixation of the product and its unpleasant feeling on the skin also occur with other forms of presentation of solid cosmetic compositions such as blushes, eye shadows, stick-bases, deodorants and the like.

[0041] A lipstick composition as described above in Table 1 was subjected to a research, in which the product was tested by 120 volunteers for 7 days, with a use frequency of about 8.8 times. A few considerations are given below, where the values are averages on a concordance scale with 5 points at most: [0042] 4.8 points—it covers the lips in a homogeneous way; [0043] 4.6 points—it colors the lips at the first application; [0044] 4.7 points—it slides on the lips, transmitting a pleasant feeling of suavity; [0045] 4.4 points—the texture is light in weight like a plume; [0046] 4.4 points—it does not flow / it does not stain; [0047] 4.4 points—its color is not altered during use; [0048] 4.5 points—it has a differentiated, creamy and at the same time lighter emollience; [0049] 4.4 points—it protects one's lips; [0050] 4.4 points—it hydrates one's lips;

Abstract
The present invention relates to a solid cosmetic composition comprising, as a structure agent, a combination consisting of a saturated straight-chain polymer and an agglutinating agent for this polymer. The composition of the inventions has a rigid, moldable and stable structure, being suitable for application as, for example, lipstick, blush, eye shadow, stick base, lip protectors (either colorful or colorless), deodorants, perfumes, among others.
Description
FIELD OF THE INVENTION [0001] The present invention relates to solid cosmetic compositions for application as, for example, lipstick, blush, eye shadow, stick base, lip protectors (either colorful or colorless), deodorants, perfumes, and others. BACKGROUND OF THE INVENTION [0002] There are many cosmetic compositions that are used for coloring and protecting lips, eyes, faces, etc. [0003] As far as lipsticks are concerned, for example, those used at present are cosmetic compositions containing structural agents such as waxes, which are products traditionally used by the consumers. However, these products are heavy, because, when applied to the lips, they are noticed, since they form a film of translucent color, without a perfect and intense covering right at the first application. [0004] Other types of lipsticks that use mixtures with linear structural agents exhibit a non-satisfactory spreadability, and one feels the friction of the lipstick while passing it on one's lips. [0005] As...
