Description

  The present invention relates to an oily solid cosmetic, and more specifically, the cosmetic of the present invention has an osmotic feeling that swells the skin, improves dryness and gloss, and further has high temperature stability. About.

Conventionally, oily solid cosmetics are widely used for lipsticks, lip balms and the like, and are expected to protect the skin and prevent drying in addition to the makeup effect. Also, these cosmetics are preferably stick-like because of their ease of application and ease of carrying. In particular, in the lip cosmetic market, there is an increasing need for lip care and a lack of burden, and various studies have been made, such as methods for reducing dryness and enhancing oil penetration.
For example, by combining a candelilla wax and a hydrogenated jojoba ester, a specific liquid oil, a specific semi-solid oil, a technique for reducing dry feeling (Patent Document 1), a non-aqueous ointment base as a main base, Lip cream technology (Patent Document 2) that spreads well and is easy to adjust by combining a polyhydric alcohol and a nonionic surfactant, and has an excellent protective effect (Patent Document 2), polyethylene wax and high-viscosity hydrocarbon oil, powder of a specific shape The technique (patent document 3) etc. which obtain oily solid cosmetics excellent in high temperature stability by combining these have been examined.

  However, a technique combining a candelilla wax with a hydrogenated jojoba ester, a specific liquid oil, and a specific semi-solid oil is excellent in improvement in dry feeling and good spread, but does not provide a penetrating feeling. In addition, the technology combining polyhydric alcohols and nonionic surfactants with a non-aqueous ointment base as the main base has good coating properties and excellent high-temperature stability. In addition, the compatibility with the oil agent is not excellent, the glossiness and color development are inferior, and in the case of a nonionic surfactant, there is a tendency to feel sticky and difficult to obtain a penetrating feeling. The technology combining polyethylene wax, high-viscosity hydrocarbon oil, and powder with a specific shape has excellent stability at high temperatures, but it has become heavier and hard to feel penetration.

Examples 1 to 9, Comparative Examples 1 to 3 Lipstick (stick shape)
Lip cosmetics having the formulations shown in Table 2 below were prepared and evaluated for the permeation and dryness, gloss and high temperature stability by the following methods. The results are also shown in Table 2.

(Production method)
A. Ingredients (1) to (6) are heated to 110 ° C. and uniformly dissolved.
B. Ingredients (7)-(19) are added to A and mixed uniformly.
C. B was filled into a stick-shaped container at 100 ° C. and solidified by cooling to obtain a lipstick.

(Evaluation method)
The following evaluation items were evaluated by the following method, and the results are also shown in Table 2.

(Evaluation item)
A. Penetration feeling b. There is no dry feeling. Sense of gloss. High temperature stability

(Evaluation method 1)
About the item of (i)-(c), the use test by 20 expert panels was done about each sample. Each panel member gave a rating based on the following absolute evaluation criteria and assigned a score. The average value of each sample was calculated from the total score of all the panels, and the determination was made according to the following criteria. For (I), whether there is a penetrating sensation that makes the lips plump, for (B), does not feel a dry feeling when applying each sample, and for (C), does it feel glossy when applying each sample? I evaluated it.

<Absolute evaluation criteria>
(Score): (Evaluation)
6: Very good 5: Good 4: Somewhat good 3: Normal 2: Somewhat bad 1: Bad 0: Very bad <Criteria>
(Judgment): (Average score)
◎: Over 5 points: Very good ○: Over 3.5 points and 5 points or less: Good △: Over 1 point and 3.5 points or less: Slightly poor ×: 1 point or less: Defect

(Evaluation method 2)
For the evaluation item (2), the state after each sample was stored at 50 ° C. for 1 month was evaluated by visual observation for the appearance of oil droplets and aqueous components (perspiration). Judged.
<Criteria>
(Judgment): (evaluation)
A: No sweating is observed.
○: Slight sweating at high temperatures, but disappears at room temperature.
Δ: Sweating is seen at a high temperature and disappears when the temperature is returned to room temperature, but a sweat mark remains on the surface.
X: Sweating is noticeable at a high temperature and does not disappear even after returning to room temperature.

As is clear from the results in Table 2, Examples 1 to 9 obtained better results in all evaluation items than the comparative examples.
On the other hand, in Comparative Example 1 containing dipropylene glycol, which is the same polyhydric alcohol, instead of component (b), the dry feeling is low because dipropylene glycol has low compatibility with the oil agent and the uniformity of the cosmetic film is poor. It lacked a lack of heat and was inferior in gloss and high temperature stability.
Instead of component (c), Comparative Example 2 using polyglyceryl-2 triisostearate, which has a close IOB value and viscosity but does not have an appropriate organic value, cannot be compatible with tripropylene glycol. Since tripropylene glycol cannot be retained in the structure, the high-temperature stability was remarkably poor, and the gloss and penetration feeling were inferior.
Comparative Example 3 using talc, which is also used as a constitutional powder in place of component (d), is inferior in the oil absorption of the oil, and therefore cannot suppress sweating at high temperatures, and is more dry due to the contained talc. It was easy to feel a feeling.
