Description

  The present invention relates to an oily cosmetic.

  As oil-based cosmetics for removing makeup stains, oil-based cleansing cosmetics have heretofore been widely used from the viewpoint of excellent cleansing effect (so-called makeup stain removal effect).

  Up to now, an oily liquid transparent composition (for example, Patent Document 1) in which a specific surfactant and an oil are blended, or an oily transparent liquid composition in which a certain amount of water and a surfactant having a specific composition are blended ( For example, Patent Document 2) discloses an attempt to prevent a reduction in cleansing power and poor appearance and feeling even when used on wet skin.

  In addition, a skin cleansing agent that combines a nonionic surfactant with a specific IOB value (Inorganic Organic Balance) in a specific ratio and is blended with an oily component and water is an attempt to achieve both cleansing effect and ease of washing with water. Is disclosed (for example, Patent Document 3).

  By the way, there are few conventional oil-based cleansing cosmetics that can sufficiently satisfy the skin feel after washing. In general, oil-based cleansing cosmetics are composed of an oil and a surfactant. The oil gives a moist and smooth feeling when applied and exhibits a cleansing effect, while the skin after washing has a stickiness and oil film. Give a feeling. In addition, the surfactant has an effect of emulsifying and washing out the oil agent, while also removing the oil content of the skin and causing squeaking on the skin after washing. For this reason, the conventional oil-based cleansing cosmetics cannot be said to sufficiently satisfy the feeling of use, such as leaving a feeling of oil film on the skin after washing or giving a squeaky feel. In the present specification, “oil film feeling” means that an oily feel remains on the skin surface. Further, in the present specification, “skin squeak” means a touch that feels a catch when a finger is moved in contact with the skin in the horizontal direction on the skin.

  Accordingly, an object of the present invention is to provide an oily cosmetic that gives a moisturizing feeling to the skin after washing, and further suppresses squeakiness, stickiness, and oil film feeling. Another object of the present invention is to provide an oily cosmetic that is excellent in a refreshing feeling after being washed up.

After the evaluation in Test 1 above, rinse the sample thoroughly with warm water of about 30 ° C., and immediately after towel drying, touch the cheek with your finger to find “no stickiness”, “no squeaking”, “moist feeling (moisturizing feeling) ) "And" oil film feeling "were sensory evaluated according to the following evaluation criteria.

<Evaluation criteria for non-stickiness>
◎ (Good): There is no feeling that the finger sticks to the cheek, and there is no stickiness.
○ (Available): Feels sticky to the cheek and feels slightly sticky, but practically acceptable.
X (defect): The finger feels sticking to the cheek, it is clearly sticky and uncomfortable for practical use.

<Evaluation criteria for lack of squeaking>
◎ (Good): Does not feel resistance (cracking) when moving a finger along the skin.
○ (Available): Although a slight resistance (cracking) is felt when moving a finger along the skin, it is practically acceptable.
X (defect): When a finger is moved along the skin, it clearly feels resistance (scrambled) and is uncomfortable for practical use.

<Evaluation criteria for moisturizing feeling>
A (good): The skin clearly feels moisture.
○ (Available): The skin feels slightly wet and does not feel dry.
X (defect): The skin feels dry (smooth).

<Evaluation criteria for oil film feeling>
A (good): The oil film feeling is hardly felt.
○ (Available): Feels a little oil film, but is practically acceptable.
X (defect): A strong oil film feeling is felt.

(Test 3: Storage stability)
The oily cosmetics obtained in each Example and Comparative Example were filled in a transparent glass container with a volume of 60 mL and stored in a thermostat kept at 5 ° C., and the oily cosmetics in the transparent glass container after storage were stored. The appearance and properties were visually observed. As a result, in Comparative Examples 1 and 2, separation was observed after 4 days, and the storage stability was poor. On the other hand, other oily cosmetics showed excellent storage stability with no significant change in appearance and properties even after storage for 1 month.

From the results of Tables 1 and 2, the oily cosmetics of the examples were usable or good in all of the familiarity, non-stickiness, lack of squeaky feeling, moist feeling (moisturizing feeling), and oil film feeling. That is, it can be seen that the oily cosmetics of the examples give a moisturizing feeling to the skin after washing, and the squeak, stickiness, and oil film feeling are suppressed. On the other hand, in Comparative Examples 1 and 2, when the HLB value of the component (A) exceeds the upper limit, the sample was separated and the storage stability was poor. For this reason, it was judged that other evaluation items could not be evaluated (indicated by “*” in the table). Comparative Example 3 was a formulation lacking the component (A), and was not squeaky and moist (moisturizing). Comparative Example 4 was a formulation lacking the component (B), and was poor in non-stickiness. Therefore, in the present invention, the combination of the component (B) and the component (C) effectively suppresses stickiness and oil film feeling caused by the component (A), and the oily makeup with a good feeling of use. When one of these components is missing, it is understood that the feeling of use is inferior. That is, the oily cosmetic of the present invention comprises a component (A) having a specific range of HLB values, a component (B) having a specific range of HLB values, an unsaturated aliphatic alcohol having 12 to 24 carbon atoms, and a carbon number. Moisturizing the skin after washing by blending as an essential component at least one component (C) selected from the group consisting of 12 to 24 branched aliphatic alcohols and pentaerythrityl tetraoctanoate It can be understood that the oily cosmetics give a feeling and control the squeakiness, stickiness, and oil film feeling, and have an excellent feeling of use.
