Description

[Technical field]

[0001] The present invention relates to a warm-sensing oil-based cosmetic preparation. [Background technology]

[0002] Conventionally, in the technical fields of massage cosmetics and cleansing cosmetics, many attempts have been made to impart a warming effect. Many of these cosmetics utilize the heat of hydration of polyhydric alcohols from the viewpoints of safety to the skin and the generation of mild heat.

[0003] Specifically, proposed products include a gel-like warm massage product containing glycerin or diglycerin, an anionic polymer compound, and water (see, for example, Patent Document 1), a massage product containing a specific polyhydric alcohol, a scrubbing agent, and a water-soluble polymer compound (see, for example, Patent Document 2), and a cleansing product containing glycerin, a specific cross-linked polymer, a specific thickener, and a specific nonionic surfactant (see, for example, Patent Document 3).

[0004] However, the heat of hydration of polyhydric alcohols causes a mild warming sensation, and the time during which the warming sensation is felt is short, making it difficult to obtain a desired warming sensation. Furthermore, although polyhydric alcohols can be easily blended into non-aqueous cosmetics that do not contain water, there is a problem that it is difficult to achieve a warming sensation even if they are blended into oil-based cosmetics in which the majority of the cosmetic is oil.

The results are also shown in Table 1.

[0066] (Test Example 1: Evaluation of formulation stability) Each sample obtained in the examples and comparative examples was filled in a 90 g wide-mouthed container and stored in a thermostatic chamber at 40° C. for one week. The condition of the agent after storage was visually observed and evaluated according to the following evaluation criteria. The evaluation was performed by five expert evaluators, and the evaluations of each evaluator were combined to determine the results.

[0067] <Evaluation criteria for formulation stability> ○ (Good): The product continues to maintain a uniform state compared to immediately after production (no change observed) △ (Insufficient): The homogeneity is maintained compared to immediately after production, but slight syneresis is observed. × (defective): The homogeneity is not maintained as compared to immediately after production, and obvious syneresis is observed.

[0068] (Test Example 2: Evaluation of Usability) Participants were asked to place 3g of each sample onto dry palms, apply it to the entire face, and massage the sample into the skin for 1 minute using small circular movements with their fingertips.

The evaluation was performed by five expert evaluators, and the evaluations of each evaluator were combined to determine the results.

[0076] <Evaluation criteria for formulation stability> ○ (Good): The product continues to maintain a uniform state compared to immediately after production (no change observed) △ (Insufficient): The homogeneity is maintained compared to immediately after production, but slight syneresis is observed. × (defective): The homogeneity is not maintained as compared to immediately after production, and obvious syneresis is observed.

[0077] (Test Example 4: Evaluation of Usability) Participants were asked to place 3g of each sample onto dry palms and apply it to the entire face, even if it was covered with makeup. They were then asked to cleanse the skin for one minute by drawing small circles with their fingertips, focusing on areas with makeup stains, until the sample was absorbed into the skin. They were then asked to rinse thoroughly with 40°C water and towel dry their faces to remove any moisture.

[0078] The usage test was conducted on the "warmth" during massage, "washing off" during washing, and "cleansing effect (effect of removing dirt)" after towel drying, and was sensory evaluated according to the following evaluation criteria. The evaluation was carried out by five expert evaluators, and the overall evaluation by each evaluator was used to determine the results.

[0079] <Warmth Evaluation Criteria> ○ (Good): Feels the optimum warmth △ (Insufficient): Feels warm, but not enough × (bad): No warmth felt

[0080] <Evaluation criteria for washability> ○ (Good): Easy to wash off △(Insufficient): Poor washability × (bad): poor washability

[0081] <Criteria for evaluating cleansing effect> ○ (Good): Excellent cleansing effect (dirt removal effect) △(Insufficient): Poor cleansing effect (dirt removal effect) × (bad): No cleansing effect (dirt removal effect)

[0082] [Table 2]

[0083] From the results in Table 2, it can be seen that the warm-sensing oil-based cosmetic compositions exhibiting the cleansing function of each Example do not separate or synergize, and exhibit significantly superior formulation stability. It can also be seen that the warm-sensing oil-based cosmetic compositions of each Example provide an optimal warm feeling during cleansing, are excellent in wash-off, and exhibit a good cleansing effect (dirt removal effect). In contrast, the comparative examples not containing the essential components of the present invention are inferior in warm feeling, wash-off, and cleansing effect, and are unable to fully exhibit the effects of the present invention.

Claims

[Claim 1] A warm-sensing oil-based cleansing cosmetic composition containing 55% by mass or more of an oil agent and containing no water, or containing water and the water content in 100% by mass of the cosmetic composition is 1% by mass or less, The following components A to C: Component A: Ca-A type zeolite 10 to 30% by mass Component B: Polyoxyethylene fatty acid glyceryl and / or polyoxyethylene fatty acid sorbitan 4 to 18% by mass Component C: fatty acid polyglyceryl 0.1 to 5% by mass The composition comprises The polyoxyethylene fatty acid glyceryl and / or polyoxyethylene fatty acid sorbitan contains at least one component selected from the group consisting of PEG-7 (caprylic / capric acid) glycerides, PEG-5 glyceryl triisostearate, PEG-20 glyceryl triisostearate, POE(20) sorbitan monooleate, and sorbeth-30 tetraoleate; The fatty acid polyglyceryl contains at least one component selected from the group consisting of polyglyceryl triisostearate and polyglyceryl-2 tetraisostearate, A warm-sensing oil-based cleansing cosmetic composition, characterized in that the average degree of polymerization of polyglycerin in the polyglyceryl triisostearate is 2 to 12.
