Background

In recent years, with the increasing demand for cosmetics, lipstick as a common cosmetic has been improved, and high demands have been made on color types, color fastness, moisture, safety, and the like.

The color fastness and the moistening degree are a pair of contradictory combinations, the lipstick with high moistening degree has poor color fastness because the content of the emollient is higher, if the color fastness is required to be ensured to be better, the amount of the emollient is greatly reduced, but at the same time, the moistening degree of the lipstick is reduced, so that the phenomena of fine lines, dry peeling and the like are caused by the loss of water of lips.

In order to improve the moistening degree and the color fastness of lipstick on the market, functional emollients can be added, the functional emollients can bring a certain color fixing effect, in order to make the color fastness better, multiple functional emollients are generally considered to be compounded, but the compounding of different functional emollients can not always achieve the positive superposition effect, and the condition that the color fastness is reduced or basically unchanged can exist, so that the lipstick which has better moistening degree and color fastness on the market is not too much, the requirements of consumers are difficult to meet, and the improvement space is provided.

The data are shown in Table 9:

TABLE 9

As can be seen from comparison of the data of comparative example 2 with that of comparative example 1 in Table 9, the L value becomes larger by adding the rosin extract, indicating that the color fastness of the rosin extract to lipstick is improved, so that lipstick is not easily discolored.

As can be seen from comparison of the data of comparative example 3 with that of comparative example 1 in Table 9, the L value becomes larger by adding the hydrogenated castor oil dilinoleate, which shows that the color fastness of the hydrogenated castor oil dilinoleate to lipstick is improved, so that lipstick is not easily faded.
