Abstract

PROBLEM TO BE SOLVED: To improve stability of especially mutable components of powder such as a perfume and the like coexisting with an extender pigment by blending aminohydroxymethylpropanediol to a powdery cosmetic material. SOLUTION: This powdery cosmetic material is blended with preferably 0.001-10 wt.%, more preferably 0.001-3 wt.% of 2-amino-2-hydroxymethyl-1,3- propanediol based on the whole amount of the cosmetic material. More preferably, the powdery cosmetic material further contains >=60 wt.% of a base pigment (e.g. talc, kaolin, sericite, white mica, etc., are cited. Talc is the most preferable.) based on the whole amount of the cosmetic material and a perfume (e.g. armoise oil basil oil, galbanum oil, etc., are cited. Especially, a citrus-based perfume such as orange oil, lemon oil, lime oil or the like is remarkably effective).

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to powder cosmetics, and more particularly to a component for improving the stability of a coexisting component.

[0002]

2. Description of the Related Art Powder cosmetics include loose powders such as white powder, baby powder and body powder, and pressed powders obtained by adding a small amount of excipients thereto. These are widely used in applications such as making the skin refreshed and keeping healthy by the action of absorbing sweat and sebum, as a matter of course, depending on the powder to be blended, and of course, the purpose of redressing. Also, by increasing the fragrance perfume rate,
It is also used to enjoy the scent and control body odor.

[0003]

However, in the case of powder cosmetics, if the amount of extender pigment to be compounded as a powder component is large, the perfume may be altered due to the surface activity of the powder, resulting in an unpleasant odor. Therefore, conventionally, in order to prevent the odor of the fragrance from being changed, various measures have been taken such as using an inactive pigment which has been subjected to a surface treatment on the extender. However, depending on the type of fragrance, even if a surface-treated extender is used, the odor of the fragrance may not necessarily be escaped, and it is difficult to obtain a fragrance excellent in fragrance stability especially at high temperatures. Was.

The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to improve the stability of a powder, particularly an easily modified component such as a fragrance coexisting with an extender.

[0005]

Means for Solving the Problems The inventors of the present invention have conducted intensive studies in order to achieve the above object, and as a result, a large amount of extender has been incorporated by adding 2-hydroxymethyl-1,3-propanediol. Even in the system, the fragrance does not change odor,
In particular, they found that the scent stability at high temperatures was improved, and completed the present invention. That is, the powder cosmetic according to the present invention comprises 2-amino-2-hydroxymethyl-1,2
It is characterized by adding 3-propanediol. In addition, the cosmetic preferably contains an extender as a powder base in an amount of 60% by weight or more based on the total amount of the cosmetic, and a fragrance.

[0006] In the above cosmetics, it is preferable that the extender is talc. In the above-mentioned cosmetics, the amount of 2-amino-2-hydroxymethyl-1,3-propanediol is 0.001 relative to the total amount of the cosmetic.
It is preferably from 10 to 10% by weight.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below. 2-Amino-2-hydroxymethyl-1,3-propanediol (Chemical Formula 1) used in the present invention is an acrylic acid-based cationic polymer compound such as a carboxyvinyl polymer which is mainly used as a thickener in the cosmetics field. It is used as a wetting agent.

[0009] The compounding amount is from 0.001% by weight to 10% by weight, particularly preferably from 0.01% by weight to 3% by weight, based on the total amount of the powder cosmetic. 0
When the content is less than 01% by weight, the effect of preventing odor change is not sufficient,
If it is blended in an amount of not less than% by weight, the usability such as the weight of elongation, stickiness, dry feeling, and stickiness may be impaired.

[0010] The powder component to be incorporated in the present invention is, in particular, an extender pigment, such as talc, kaolin, sericite, and muscovite.

As these powder components, those which have not been subjected to surface treatment of the powder can be used, but those having been subjected to surface treatment are particularly preferable. The method of surface treatment is not particularly limited, but metal soap,
Examples of the treatment include silicones and fatty acid esters.

As is clear from Table 1, when a fragrance is blended with talc, the fragrance deteriorates particularly during storage at high temperatures (Test Examples 2 and 4). In the case of using talc treated with metal soap (Test Example 2), the degree of alteration is improved but not sufficient as compared with the case of using untreated talc (Test Example 4). In contrast, 2-amino-2-hydroxymethyl-

In addition, the degree of unpleasant odor was suppressed irrespective of the untreated talc (Test Example 2) and the metal soap-treated talc (Test Example 4), and it was particularly effective in improving the fragrance stability during high-temperature storage. .

Next, the present inventors studied the amount of 2-amino-2-hydroxymethyl-1,3-propanediol. Evaluation of usability is based on the weight of elongation,
Each item of stickiness, dry feeling, and long-lasting makeup was mainly checked. Confirmation was based on judgment by a specialized panel in the cosmetics field. ：: No problem Δ: Slightly poor ×: Poor The results are shown in Table 2 below.
