Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

FIELD OF THE INVENTION The present invention relates to lipstick compositions, in particular, to their long-term storage stability and to their improved luster and usability.

[0002]

2. Description of the Related Art Generally, a lipstick composition contains a wax and various liquid oils. In recent years, gloss has recently been required for applying lipstick, and lanolin and heavy liquid isoparaffin are used as oils for imparting gloss. It is widely used.

[0003]

However, lanolins have been found to generate a bad odor due to oxidative deterioration, and in particular, lipstick compositions may be stored for a long period of time before and after their sale, and lip Since it is applied to a part where the odor is easily felt, generation of offensive odor has been a very serious problem.

[0004] Further, heavy liquid isoparaffins themselves have high viscosities, and therefore, when mixed in a lipstick composition in a large amount, phenomena such as poor usability, especially poor spreadability, have been observed. The present invention has been made in view of the above-mentioned problems of the related art, and an object of the present invention is to provide a lipstick composition having light usability and excellent long-term storage stability without impairing gloss. .

[0005]

Means for Solving the Problems In order to achieve the above object, the present inventors have studied in detail that, by combining hydrogenated rosin isostearate and heavy liquid isoparaffin in combination, lanolin and They have the function of imparting the same luster, and have found that by combining methylphenylpolysiloxane, the usability is greatly improved without impairing the luster, and the present invention has been completed. That is, the lipstick composition according to the present invention is characterized by containing hydrogenated rosin isostearate glyceryl, heavy liquid isoparaffin, and methylphenylpolysiloxane.

In the lipstick composition according to the present invention, the hydrogenated rosin isostearate glyceryl is 5 to 20%.
% By weight, and 10 to 30% by weight of heavy liquid isoparaffin
And 10 to 30% by weight of methylphenylpolysiloxane
It is preferred that they are blended. In the lipstick composition according to the present invention, it is preferable that the average molecular weight of the heavy liquid isoparaffin is from 500 to 3,000.

[0007]

Embodiments of the present invention will be described below. Note that the present invention is not limited to the following embodiments. The hydrogenated rosin glyceryl isostearate in the present invention has the following structural formula.

[0008]

Embedded image The amount of the hydrogenated rosin glyceryl isostearate in the composition is preferably 5% by weight or more in order to obtain good gloss. The upper limit of the amount of hydrogenated rosin glyceryl isostearate is preferably 20% by weight or less. It is not preferable not only to improve the gloss but also to increase the glossiness when blending beyond this.

In the present invention, the heavy liquid isoparaffin used for improving luster together with the hydrogenated rosin glyceryl isostearate includes isobutene and n
A mixture of saturated type long-chain hydrocarbons having a hydrogenated side chain including a terminal double bond in a butene copolymer. Various polymerization degrees can be obtained by changing the polymerization conditions. In the present invention, those having an average molecular weight of 500 to 3,000 can be preferably used from the viewpoints of availability, viscosity, and the like, and those having a molecular weight of around 1,000 are particularly optimal. The blending amount of the heavy liquid isoparaffin in the composition is preferably 10% by weight or more for improving gloss. Also, the upper limit of heavy liquid isoparaffin is
It is preferably at most 30% by weight in view of the relative relationship with other components. If it is added more than this, it may become heavier in terms of growth.

In the present invention, methylphenylpolysiloxane is blended in order to suppress the spread of the lipstick composition. To obtain the effect, it is necessary to blend 10 to 30% by weight of methylphenylpolysiloxane. And the viscosity of methylphenylpolysiloxane is from 5 to 100.
cs is preferred. If the amount is less than 10% by weight, the material tends to be heavier in terms of elongation, and if it is more than 30% by weight, the gloss tends to be poor.

[0011] In the present invention, any other hydrocarbon-based wax may be used as long as it is generally used in cosmetics and the like. Examples thereof include microcrystalline wax, carnauba wax, candelilla wax, polyethylene wax, and ceresin wax. No. The compounding amount of the hydrocarbon wax varies depending on the solidifying power for the oil component, but is preferably 0.5 to 25% by weight, more preferably 3 to 10% by weight, based on the total amount of the lipstick composition. 0.
If the amount is less than 5% by weight, the shape-retaining property cannot be maintained. If the amount exceeds 25% by weight, glossiness may be lost.

The lipstick composition for polish of the present invention may contain waxes, oils, water, humectants, surfactants, pigments, resins, clay minerals, if necessary, as long as the effects of the present invention are not impaired.
Antioxidants, preservatives, UV inhibitors, fragrances and the like can be added.

[0013]

Next, the present invention will be described in more detail by way of examples. The present invention is not limited thereby.
The compounding amount is% by weight. The present inventors conducted various tests in examining the lipstick composition of the present invention. Prior to the examples, the effect test method and evaluation criteria will be described.

[0019]Conventional technology  First, it is the conventional lipstick composition or gloss component of the following table
Preparation of lipstick composition containing a large amount of lanolin as before
Then, each of the above tests was performed. Comparative Example 1 contains no gloss component
Lipstick composition. Comparative Examples 2 to 6 all have
It is a lipstick composition containing lanolin.

From the above results, it can be seen that Comparative Example 1, which is a lipstick composition containing no lanolin as a gloss component, has no problem in odor, but is inferior to gloss. On the other hand, it can be seen that the lipstick compositions of Comparative Examples 2 to 6, in which the gloss component lanolin is blended, are excellent in gloss but have a problem in odor due to deterioration. Therefore, it can be seen that a lipstick composition containing a large amount of lanolin as in the past is not suitable for long-term storage.

[0022]Structural component  Therefore, the present inventors reduced the amount of lanolin as little as possible.
Lipstick composition with excellent gloss gloss equivalent to comb and lanolin
We studied to obtain. Tables 2 and 3 below show the
The composition and test results of the lipstick composition obtained in the above steps are shown.

From the above results, it can be seen that the lipstick compositions of Examples 1 and 2 according to the present invention containing all of hydrogenated rosin glyceryl isostearate, heavy liquid isoparaffin and methylphenylpolysiloxane have three points of growth, gloss and smell. You can see that both are excellent. Also, it can be seen from the comparison with Table 1 that gloss equal to lanolin was achieved.

On the other hand, Comparative Example 7 does not contain methylphenylpolysiloxane, indicating that it is considerably inferior in spreadability. Further, among the configurations of Examples 1 and 2, Comparative Examples 8 and 9 in which methylphenylpolysiloxane was changed to dimethylpolysiloxane of the same silicone oil were inferior in gloss. Although not shown in the above table, the use of ester oil or liquid paraffin in place of methylphenylpolysiloxane also tends to reduce gloss.

Therefore, it can be seen that only methylphenylpolysiloxane improves the spread without shining. Next, Table 3 shows the results of studies on components other than the silicone-based oil component.

[0027]

From the above results, it can be seen that the composition of Comparative Example 10, which lacked the constitution of hydrogenated rosin isostearate from the essential constituents of the present invention, was not yet sufficient in terms of elongation and gloss. Although not shown in the above table, a composition lacking the composition of heavy liquid isoparaffin also showed insufficient growth and gloss.

Example 3 containing a relatively small amount of lanolin
In the composition of Example 4, there is no problem in blending lanolin up to about 5% by weight, as can be seen from the fact that there is no problem in the evaluation of odor (long-term storage stability).
However, as can be seen from Comparative Example 11, even if lanolin is added in an amount of about 5% by weight, luster as a lipstick composition cannot be imparted at this level.

Therefore, from Tables 2 and 3, the composition containing hydrogenated rosin isostearate glyceryl, heavy liquid isoparaffin, and methylphenylpolysiloxane was superior in all of the three aspects of growth, gloss, and smell for the first time. It turns out that it becomes a lipstick composition. Test examples 1 and 40 in which the average molecular weight of heavy liquid isoparaffin was 2000
From the evaluation results of Test Example 2 of 00, it is understood that the average molecular weight of the heavy liquid isoparaffin in the present invention is preferably up to about 3000.

Compounding amount  Next, the amount of hydrogenated rosin glyceryl isostearate
Was considered. The results are shown in the table below.

The above results show that the blending amount of hydrogenated rosin glyceryl isostearate is preferably about 5 to 20% by weight. In addition, when Test Example 7 and Test Example 8 were compared, Test Example 8 in which the content of heavy liquid isoparaffin was large showed heavier growth. Test Example 3 is an example in which the compounding amount of heavy liquid isoparaffin and methylphenylpolysiloxane is small. When the compounding amount of other components is small, the compounding amount of hydrogenated rosin isostearate is 5% by weight. In some cases, the gloss and the like are inferior.

[0033]Compounding amount of heavy liquid isoparaffin  Next, the amount of heavy liquid isoparaffin was examined.
Was. The results are shown in the table below.

From the above results, if the amount of the heavy liquid isoparaffin is less than 10% by weight, the luster is inferior, and
It can be seen that when the content is more than the weight%, the growth becomes worse. Therefore, it is understood that the amount of the heavy liquid isoparaffin is preferably 10 to 30% by weight.

[0035]Compounding amount of methylphenylpolysiloxane  Next, consider the amount of methylphenylpolysiloxane
went. The results are shown in the table below.

From the above results, it can be seen that when the blending amount of methylphenylpolysiloxane is less than 10% by weight, the spread is inferior, and when it exceeds 30% by weight, the gloss becomes poor. Therefore, it is understood that the amount of methylphenylpolysiloxane is preferably from 10 to 30% by weight.
