Description

[Technical field]

[0001] The present invention relates to anhydrous compositions, in particular to anhydrous cosmetic compositions. [Background technology]

[0002] In the field of cosmetics, there are anhydrous cosmetics that contain no water or only a small amount of water. Anhydrous cosmetics typically contain at least one oil as a main ingredient.

[0003] Anhydrous cosmetics tend to have a greasy or oily feeling after application, which is uncomfortable. The greasy or oily feeling of anhydrous cosmetics can be reduced if the viscosity of the anhydrous cosmetics is reduced. However, it is difficult to apply low-viscosity anhydrous cosmetics to keratinous materials such as skin because they drip. Therefore, it is preferable to thicken or gel the anhydrous cosmetics using at least one gelling agent. On the other hand, it is difficult to apply high-viscosity anhydrous cosmetics evenly.

[0004] WO 2021 / 132045 discloses an anhydrous composition comprising, as an organic lipophilic gelling agent, ethylenediamine / stearyl dimer dilinoleate copolymer in an amount of 5% by weight, based on the total weight of the anhydrous composition. [Prior art documents] [Patent documents]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] After extensive investigation, the inventors have discovered that it is possible to provide an anhydrous composition which can be thickened, have suitable applicability, provide good smoothness during application, and also reduce greasiness after application.

[0022] Thus, one aspect of the present invention is (a) at least one oil other than a fatty alcohol; (b) at least one organic lipophilic gelling agent selected from urethane polymers; (c) at least one aliphatic alcohol, and (d) at least one peeling agent The anhydrous composition comprises:

[0023] The term "anhydrous" composition means herein a composition that does not contain water or that contains less than 3% by weight, preferably less than 1% by weight, more preferably less than 0.1% by weight of water relative to the total weight of the composition.

[0024] The anhydrous compositions according to the present invention can be thickened, have suitable application properties, provide good smoothness during application and also reduce greasiness after application.

[0025] Since the anhydrous composition according to the invention comprises (b) at least one organic lipophilic gelling agent, the anhydrous composition according to the invention is thickened and is preferably in the form of a gel, i.e. an oil-gel.

[0026] The term "gel" as used herein includes thick liquids that may be Newtonian or non-Newtonian. Newtonian fluids refer to fluids whose viscosity does not change with changes in flow conditions. Gels also include shear-thinning gels.

[0027] In one preferred embodiment of the present invention, the anhydrous composition according to the present invention may be a gel having a non-Newtonian viscosity. In another preferred embodiment of the present invention, the anhydrous composition according to the present invention may be shear-thinning. A non-Newtonian shear-thinning material changes state from a gel to a liquid in the presence of an applied shear stress and reverts to a gel in the absence of an applied shear stress. A shear-thinning material is, by definition, one in which the viscosity of the material decreases non-linearly when the applied shear stress is increased.

[0028] The anhydrous composition according to the invention may be characterized by its rheological properties: the anhydrous composition according to the invention may have a storage modulus (G') of 50 Pa to 10,000 Pa, preferably 100 Pa to 7,500 Pa, more preferably 500 Pa to 5,000 Pa.

[0029] The storage modulus (G') can be measured using a rheometer with 40 mm parallel plates and the following conditions: Setting interval: 500μm Temperature: 25°C Strain(%): 1% Frequency: 1Hz

[0030] The anhydrous composition according to the present invention can have suitable applicability because a storage modulus (G') of 50 Pa or more can ensure that the anhydrous composition is not easily destroyed before application, and a storage modulus (G') of 10,000 Pa or less can ensure that the anhydrous composition does not become a hard solid that is difficult to apply.

[0031] When the anhydrous composition according to the present invention has the above storage modulus (G'), (d) the peeling agent can be well dispersed in the anhydrous composition, and therefore the anhydrous composition according to the present invention can effectively peel off the superficial layer of keratinous materials such as the stratum corneum of the skin.

[0032] When the anhydrous composition according to the present invention comprises (f) a skin care active ingredient, the (f) skin care active ingredient can penetrate the skin well.

EXAMPLES

[0182] The present invention will now be described in more detail by way of examples. However, these examples should not be construed as limiting the scope of the present invention.

[0183] (Examples 1 to 3 and Comparative Example 1) Each of the compositions of Examples 1 to 3 and Comparative Example 1 was prepared by mixing the components shown in Table 1. All numerical values ​​for the amounts of components in Table 1 are based on "mass %" of the raw materials.

[0184] [Table 1]

[0185] [evaluation] (Visual Aspects) The visual aspects of the compositions of Examples 1 to 3 and Comparative Example 1 were evaluated according to the following criteria. Good: transparent gel Poor: Non-transparent gel (opaque solution)

[0186] The results are shown in Table 1.

[0187] (Storage modulus) The storage modulus G' of the compositions of Examples 1 to 3 was measured using a Discovery Hybrid Rheometer 2 (TA Instruments) with 40 mm parallel plates set at a distance of 500 μm under conditions of a frequency of 1 Hz and an oscillatory strain of 1% at 25° C. The storage modulus G' of the composition of Comparative Example 1 could not be measured because it was not a gel.

[0188] The results are shown in Table 1.

[0189] (Smoothness) Ten expert judges evaluated the "smoothness" during application of the compositions of Examples 1 to 3. Each judge took about 5 g of each composition, then applied it by gently rubbing it on his / her hand for 1 minute, evaluated the smoothness during application, and scored it from 1 (bad) to 5 (very good), and then classified it into the following four categories based on the average of the scores: Very good: 5.0~4.0 Good: 3.9~3.0 Bad: 2.9~2.0 Very poor: 1.9~1.0

[0190] The smoothness during application of the composition of Comparative Example 1 was not evaluated because it was not a gel, and therefore the results of Comparative Example 1 could not be compared to those of Examples 1-3.

[0191] The results are shown in Table 1.

[0192] (Olivia) Ten expert judges evaluated the "greasiness" after application of the compositions of Examples 1 to 3. Each judge took about 5 g of each composition, then applied it by gently rubbing it on his / her hands for 1 minute, evaluated the greasiness after application, and scored it from 1 (bad) to 5 (very good), and then classified it into the following four categories based on the average score. Very good: 5.0~4.0 Good: 3.9~3.0 Bad: 2.9~2.0 Very poor: 1.9~1.0

[0193] The results are shown in Table 1.

[0194] The greasiness after application of the composition of Comparative Example 1 was not evaluated because it was not a gel, and therefore the results of Comparative Example 1 could not be compared to those of Examples 1-3.

[0195] (Summary) The compositions of Examples 1 to 3 containing components (a) to (d) in the composition of the present invention were in the form of a gel, had a storage modulus of 50 Pa to 10,000 Pa (meaning that these compositions had suitable applicability), imparted smoothness during application, and were less greasy after application.

[0196] It should be noted that the amount of HDI / trimethylolhexyllactone crosspolymer corresponding to component (b) in the compositions of Examples 1 to 3 was not large. It is surprising that a small amount of component (b) can thicken the compositions of Examples 1 to 3.

[0197] On the other hand, the composition of Comparative Example 1, which did not contain component (b), was not in the form of a gel. Therefore, the composition of Comparative Example 1 could not be compared with the compositions of Examples 1 to 3 in terms of storage modulus and smoothness and greasiness.

[0198] It should be noted that ethylenediamine / stearyl dimer dilinoleate copolymer is a class of polyamides and is not a urethane polymer, so the ethylenediamine / stearyl dimer dilinoleate copolymer contained in the composition of Comparative Example 1 does not correspond to component (b) in the composition of the present invention.
