Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a powder cosmetic, and more particularly, it is possible to take out a necessary amount of a required amount with a small force without caking in a solid state after press molding or the like. The present invention relates to a powdery cosmetic which is capable of being loose and free of agglomerates having a size that impairs the feel and finish, has no dustiness, has a moist feeling, and has no stickiness.

[Problems to be solved by conventional technology and invention]

It is mainly used as a solid type or a loose type which contains oil containing a solid oil and / or a liquid oil as a main component and is filled into a container such as an inner plate by press molding or casting. Cosmetics used for make-up are generally referred to as powder cosmetics.

Such powder cosmetics usually prevent powderiness,
For the purpose of obtaining a moist feeling, a solid fat (solid oil) and a liquid oil are combined with an oil content of up to about 50%.

However, when the powder cosmetic is a solid type, if a large amount of such an oil is blended, a moist touch can be obtained, but a large amount of oil penetrates between the particles of the powder, and as a result, the press-formed product has a caking property. Or the phenomenon that the surface of the molded article becomes too smooth due to repeated use and the required amount cannot be taken out by ordinary use (a phenomenon generally called “shininess” because the surface is glossy). It has the disadvantage of inviting. In particular, when an organic low-molecular pigment is contained, this disadvantage is remarkable, and it has generally been difficult to blend an oil content of 10% or more.

In addition, when an oil is added to a loose type powder cosmetic containing an organic plate-like powder, the powder agglomerates via the oil to form a lump, which not only impairs the feel, but also makes the cosmetic finish uneven and uneven. Has the disadvantage of becoming

Therefore, studies have been conducted on oils that are highly effective in preventing powderiness and imparting a moist texture, but there has been no fundamental solution to prevent oiliness and prevent moist feeling when used. No satisfactory powder cosmetics have been obtained.

Therefore, the development of a solid-type powder cosmetic and a loose-type powder cosmetic that does not cause a caking phenomenon and “shininess” and has a good feeling in use and does not cause agglomeration of the powder have been eagerly desired.

[Means for solving the problem]

Under such circumstances, the present inventor has conducted intensive studies to solve the above-mentioned problems. As a result, if a non-volatile fluorine-based liquid oil having a low surface tension is added to the powder cosmetic, the powder cosmetic may be powdery. It has a moist feel, and furthermore, it has been found that caking and `` shininess '' do not occur in the case of the solid type, and that the powder does not agglomerate in the case of the loose type, and to complete the present invention.

In addition, the measurement of the number of plate-like crystal particles is performed under a scanning electron microscope, but only those having an independent shape are counted, and the periphery is not clear or a simple pattern of the particle surface or a simple pattern of the particle surface. What is not counted as one particle.

The alkali metal monoalkyl phosphate (IV) has a degree of neutralization of 0.8 to 1.2, represented by the general formula (V): (Wherein, R represents a saturated or unsaturated linear or branched hydrocarbon group having 8 to 32 carbon atoms) and an alkali metal salt of a monoalkyl phosphoric acid (V) represented by the general formula (VI) X _m Y _n (VI) (wherein, X represents zinc, Y represents an inorganic anion or an organic acid anion, and m and n each represent an integer corresponding to the valency of Y and X) It is produced by reacting by salt exchange and then adjusting the pH of the system to the range of 2-6.

If the particle size exceeds 6, the particle shape of the alkali metal monoalkyl zinc phosphate becomes largely indefinite and the performance such as feeling of use is significantly reduced. Further, in order to provide an excellent feeling in use, it is necessary to adjust the pH of the system to 2 to 6, preferably 3 to 5. Further, the adjustment of the pH of the system can be regulated by the amount of the alkali compound added. The alkali compound to be added to adjust the pH is 0.3 to 0.7 equivalents relative to the alkali metal salt of monoalkyl phosphoric acid (V).
Preferably, it is 0.45 to 0.55 equivalent. As such an alkali compound, an alkali metal hydroxide salt is preferable, and sodium hydroxide and potassium hydroxide are particularly preferable. The method of adjusting the pH of the reaction solution is not limited at all,
For example, the adjustment may be performed after the addition of the zinc salt (VI), or the adjustment may be performed at the same time as the addition of the zinc salt (VI) to keep it constant.

[Action and effect of the invention]

The powder cosmetics containing the fluorinated liquid oil (A) or another oil and an organic low-molecular pigment were evaluated for ease of removal and moist feeling. Table 1 shows the results.

(Evaluation method) N ^epsilon - 0.4 to 4 each oil to lauroyl -L- lysine 20g.
The mixture was mixed using a 0 g pulverizer and then press-molded to prepare a solid type powder cosmetic. Ease of removal was evaluated by the amount of powder that could be picked up by the finger when the surface of the cosmetic was lightly rubbed with the finger. The moist feeling was also evaluated.

(Evaluation criteria) Evaluation of ease of removal: 5: Very good 4: Good to take 3: Good to take 2 ... Difficult to take 1 ... Not good Evaluation of moist feeling: 5 ... Very moist 4 ... Moist 3 ... Normal 2 ... Slightly powdery 1 ... Powdery In addition, samples of No.7 and No.10 are very difficult to take,
The moist feeling could not be evaluated because it could not be applied well on the skin when used in a normal makeup operation.

As is clear from the results in Table 1, when the perfluoropolyether according to the present invention was used as an oil agent, it was mixed with N ^ε -lauroyl-L-lysine, which is a raw material powder of a general powder cosmetic, and press-molded. The ease with which it was removed was significantly improved. In addition, even if the amount of perfluoropolyether was increased, it did not become difficult to remove.

However, in the case of squalane and dimethylpolysiloxane, which are oil agents generally used in the past, as the blending amount increases, the powder bonding force increases, the powder is agglomerated, and the pressed product is pressed with a finger. When I tried to rub the surface of the sample, it showed "shininess".

Therefore, the powder cosmetic of the present invention is an excellent cosmetic having both moist feeling and usability such as ease of taking.
Further, in the present invention, even if the compounding amount of the fluorine liquid oil agent of the component (A) is larger than that of the conventional oil agent, it is not difficult to remove the oil agent. Useful.
