Technical Field

[0001] The present disclosure relates to personal care compositions comprising: (a) a volatile alkane mixture comprising, relative to the total weight of the alkane mixture, from about 10% to about 90% by weight of linear alkanes having 9 to 18 carbon atoms and from about 10% to about 90% by weight of branched alkanes having 10 to 14 carbon atoms; and (b) one or more non-volatile resins selected from silicone resins, hydrocarbon resins, organic resins, fluorinated resins, and combinations thereof. The present disclosure also relates to the aforementioned linear alkanes comprising, relative to the total weight of the alkane mixture, from about 0% to about 5% by weight of n-decane, from about 50% to about 80% by weight of n-dodecane, from about 1% to about 5% by weight of n-tetradecane, and from about 0% to about 5% by weight of n-hexadecane or n-octadecane. Background Art

[0002] Resins, alone or in combination with plasticizers, are commonly used as film formers in skin care, makeup, and sunscreen applications to achieve water resistance and long wear. However, the processability of resins in cosmetically acceptable carriers (e.g., cyclomethicone) is difficult, and it takes a long time to dissolve the resin powder in silicone-based solvents. However, hydrocarbon-based solvents such as isododecane can easily dissolve the resin powder. However, because isododecane dries too quickly, the feel of the personal care formulation is uncomfortable. Therefore, there is a need to develop personal care formulations containing alkane mixtures that can easily dissolve the resin powder and also provide excellent sensory benefits.

[0072] Example 1

[0073] Preparation of Alkane Mixture Examples 1-3

[0074] The linear alkane mixture of the present invention is prepared as described in EP2417199A1.10 -C 12 The alkanes were combined and stirred until a homogeneous solution was formed. Table 1 lists the compositions of alkane mixtures Examples 1-3.

[0075] Table 1

[0076]

[0077] Example 2

[0078] Preparation of Personal Care Formulation 1

[0079] 1 g of trimethylsiloxysilicate (MQ resin) and 4 g of alkane mixture Example 2 were mixed at room temperature and 3000 rpm for 1 minute using a vortex mixer. After standing for another minute at room temperature, the mixture was photographed. Figure 1 photos.

[0080] 1 g of trimethylsiloxysilicate (MQ resin) and 4 g of cyclopentasiloxane were mixed at room temperature and 3000 rpm for 1 minute using a vortex mixer. After standing for another minute at room temperature, the mixture was photographed. Figure 2 photos.

[0081] When compared Figure 1 and Figure 2 In the picture above, it can be clearly seen that in the alkane mixture all of the silicone resin is completely dissolved, whereas in the cyclopentasiloxane white lumpy residues of the silicone resin are still clearly visible and are not easily dissolved.

[0082] The surprising uniqueness of the alkane mixture as a solvent for resins such as trimethylsiloxysilicate can be demonstrated when comparing it to typical alkane solvents commonly used in the cosmetics industry, particularly in color cosmetics, such as isododecane.

[0083] Figure 3 The graph in shows the weight loss of a solution of trimethylsiloxysilicate (MQ resin) in alkane mixture Example 2 and a solution of trimethylsiloxysilicate (MQ resin) in isododecane. Figure 3 The graph in shows that the isododecane solution has a higher weight loss, since isododecane evaporates significantly faster than the alkane mixture example 2. This results in two different films after a further evaporation time of 24 hours, as shown in FIG. Figure 4 As shown in the picture.

[0084] like Figure 4 As shown in (A) (trimethylsiloxysilicate (MQ resin) in isododecane), the film is brittle and hard and shows visible cracks. Figure 4As shown in (B) (trimethylsiloxysilicate (MQ resin) in alkane mixture example 2), the film is smooth and soft without any visible cracks. It is widely recognized by experts in the field that hard and brittle films are disadvantageous in terms of wear comfort.

[0085] These results indicate that Alkane Mixture Example 2 provides enhanced benefits to cosmetic formulators and consumers, such as superior long-lasting and comfortable makeup wear.
