Description

Cosmetic product

RELATED APPLICATIONS

The present application claims priority from japanese patent application No. 2018-131071, filed on 7/10 in 2018, and is incorporated herein by reference.

Technical Field

The present invention relates to cosmetics, and more particularly to cosmetics that are smooth, although having a matte cosmetic effect.

Background

The texture of the skin or lips to which the cosmetics are applied is roughly classified into the following two types: giving a glossy feel and a matte feel. Among them, many of the liquid cosmetics having a matte texture are poor in smoothness, and wrinkles become noticeable with time. Further, a cosmetic having a matte feel is too hard to be formed into a tube, and is applied not directly from a container but using an applicator previously placed in a container, or is filled in a container for an inner tray or a jar type (for example, refer to patent document 1).

The powder of the present invention needs to contain dextrin palmitate.

The blending amount of dextrin palmitate is required to be 3.5 to 10% by mass based on the total amount of the cosmetic. Further, it is preferably 4 mass% or more. If the blending amount of dextrin palmitate is too small, the stability is poor.

Further, it is preferably 9 mass% or less. If the blending amount of dextrin palmitate is too large, the smoothness of spreading is impaired.

Further, as the powder, a plate-like powder is preferably used. If spherical powder is used, the feeling of use may be deteriorated.

Before the description of the examples, the evaluation test method employed in the present invention will be described.

Evaluation (1): hardness measurement test

The hardness of the sample before filling of the container was measured using a rheometer manufactured by Sun science Co., ltd., under the following conditions (load: 2kg, needle diameter: 5.6)φNeedle penetration depth: 3mm, rise speed: 20 mm/min, determination temperature: 25℃).

Evaluation (2): use feeling (smoothness, matte feeling, inconspicuous degree of longitudinal wrinkles, moist feeling)

Samples were applied to lips by 10 panelists, and the feeling of use (smoothness, matt feeling, inconspicuous degree of longitudinal wrinkles, moist feeling) at the time of application was evaluated.

A: more than 9 answers were good in feel of use (smooth, matt, inconspicuous longitudinal wrinkles, moist);

b:8 answers are good in use feeling;

c:7 answers are good in use feeling;

d: more than 5 and less than 7 answers are good in use sense;

e: the 4 answers are good in use sense;

f: less than 4 answers gave good feeling of use.

The samples evaluated as E and above were good in use feeling, and F was poor in use feeling.

Evaluation (3): stability of

The sample was stored at low temperature (5 ℃) and high temperature (40 ℃) for 30 days, and compared with a standard stored at normal temperature (25 ℃) to confirm whether separation or not was present.

G: no separation;

b: there is a separation.

The present inventors produced cosmetics (lip cosmetics) shown in tables 1 and 2 below by a conventional method, filled the cosmetics into a tubular container, and measured according to the evaluation method described above. The results are shown in tables 1 and 2.

TABLE 1

TABLE 2

From test example 1-1, it is clear that: when the blending amount of the volatile oil component is 3 mass%, the matte feel cannot be satisfied.

From test examples 1 to 4 and 1 to 5, it is clear that: by increasing the blending amount of the tri (caprylic/capric) glyceride as the polar oil component (nonvolatile liquid oil component), the matte feeling or wet feeling is improved.

From test examples 1 to 6, it can be seen that: in the case of less dextrin palmitate, stability tends to be poor.

Next, the present inventors studied the P/V ratio. The present inventors produced cosmetics (lip cosmetics) shown in table 3 below by a conventional method, filled the cosmetics into a tubular container, and measured by the above evaluation method. The results are shown in Table 3.

TABLE 3

From table 3, it is clear that: if the P/V ratio is too low, the smoothness is provided, but the matte feel is insufficient; if the P/V ratio is too high, the matte feeling is high, but the smoothness and the wet feeling tend to be insufficient.

Based on these results, the cosmetic according to the present invention is characterized in that: comprises the following powder (P) and oil component (V) and the P/V ratio is 0.30-0.75,
