Description

The present invention relates to a composition, especially a cosmetic composition, which can prevent or reduce the odor of the composition.

Cinnamic acid and its derivatives, such as ferulic acid, are known to be useful, for example, in the field of cosmetics, because they can function as UV filters and the like. However, they tend to be unstable under some conditions. For example, ferulic acid is soluble in water under alkaline conditions, but aqueous solutions of ferulic acid can discolor rapidly.

US Pat. No. 6,632,444 discloses stabilizing ferulic acid under specific conditions with a non-volatile polyol such as propylene glycol in water having a pH of about 3 to about 5. It is described in US Pat. No. 6,632,444 that aqueous compositions containing ferulic acid and a non-volatile polyol under certain conditions and having a pH of about 3 to about 5 do not discolor rapidly.

It is preferred that the (b) oil has a logP value of 7.0 or less, more preferably 6.5 or less, and even more preferably 6.0 or less. It may be preferred that the (b) oil has a logP value of 1.0 or higher, more preferably 1.5 or higher, even more preferably 2.0 or higher.

An example is Epiwin software manufactured by the US Environmental Agency.

This value may be calculated, in particular, using the ACD (Advanced Chemistry Development) Solaris software V4.67; this value is also available from Exploring QSAR:hydrophobic, electronic and steric constants (ACS professional reference book, 1995).

(Examples 1 to 8 and Comparative Examples 1 to 8)
[Preparation]
Each of the compositions according to Examples 1-8 and Comparative Examples 1-8 was prepared by mixing the components shown in Table 1 and Table 2. All numerical values relating to component amounts are based on "wt%" of the active ingredient.

Tables 1 and 2 provide the following information regarding the compositions according to Examples 1-8 and Comparative Examples 1-8.
(1) In the "pH" column, the pH value of the composition
(2) In the column ``Presence of a good solvent'', it is determined whether the composition contains a good solvent for ferulic acid (isopropyl lauroyl sarcosinate or bis-ethoxydiglycol cyclohexane 1,4-dicarboxylate). Or “without”.

[Evaluation]
(PVG)
The amount (%) of p-vinyl guaiacol (PVG) in each composition according to Examples 1 to 8 and Comparative Examples 1 to 8 was measured by HPLC system (column: Inertsil ODS-3 (particle size 5 μm, length 150 mm × diameter 4.6. mm, mobile phase material: 0.2% acetic acid in water/acetonitrile (6/4), flow rate: 1 mL/mn, injection volume of composition: 10 μm, no gradient). It was determined as the ratio of the peak area of PVG to the peak area (in %).

The results of the measured values are shown in Tables 1 and 2.

A lower amount of PVG in the composition is preferred as PVG can cause odors.

A comparison between Example 1 and Comparative Example 1 shows that the amount of PVG in the composition according to Example 1 is less than the amount of PVG in the composition according to Comparative Example 1, and a reduction in the amount of PVG. It is due to the use of the good solvent (isopropyl lauroyl sarcosinate) in the composition according to Example 1, rather than the poor solvent for ferulic acid in the composition according to Comparative Example 1 (ethylhexyl palmitate).

A comparison between Example 2 and Comparative Example 2 shows that the amount of PVG in the composition according to Example 2 is less than the amount of PVG in the composition according to Comparative Example 2, and the reduction of the amount of PVG is It is to attribute the use of the good solvent (isopropyl lauroyl sarcosinate) in the composition according to Example 2 to the poor solvent for ferulic acid in the composition according to Comparative Example 2 (ethylhexyl palmitate).

It should be noted that the amount of PVG in the composition according to example 2 is less than the amount of PVG in the composition according to example 1. This can be attributed to the higher amount of good solvent for ferulic acid in the composition according to example 2 than in the composition according to example 1.

It should be noted that the amount of PVG in the composition according to Example 3 is less than the amount of PVG in the composition according to Example 2. This can be attributed to the higher amount of good solvent for ferulic acid in the composition according to Example 3 than in the composition according to Example 2.

A comparison between Example 4 and Comparative Example 4 shows that the amount of PVG in the composition according to Example 4 is less than the amount of PVG in the composition according to Comparative Example 4, and the reduction in the amount of PVG is It is to use the good solvent in the composition according to Example 4 (isopropyl lauroyl sarcosinate) instead of the poor solvent for ferulic acid in the composition according to Comparative Example 4 (ethylhexyl palmitate).

A comparison between Example 5 and Comparative Example 5 shows that the amount of PVG in the composition according to Example 5 is less than the amount of PVG in the composition according to Comparative Example 5, and the reduction in the amount of PVG is It is to use the good solvent in the composition according to Example 5 (isopropyl lauroyl sarcosinate) rather than the poor solvent for ferulic acid in the composition according to Comparative Example 5 (ethylhexyl palmitate).

It should be noted that the amount of PVG in the composition according to Example 5 is less than the amount of PVG in the composition according to Example 4. This can be attributed to the higher amount of good solvent for ferulic acid in the composition according to Example 5 than in the composition according to Example 4.

A comparison between Example 6 and Comparative Example 6 shows that the amount of PVG in the composition according to Example 6 is less than the amount of PVG in the composition according to Comparative Example 6, and a reduction in the amount of PVG. It is due to the use of a good solvent in the composition according to Example 6 (isopropyl lauroyl sarcosinate), rather than a poor solvent for ferulic acid in the composition according to Comparative Example 6 (ethylhexyl palmitate).

It should be noted that the amount of PVG in the composition according to Example 6 is less than the amount of PVG in the composition according to Example 5. This can be attributed to the higher amount of good solvent for ferulic acid in the composition according to example 6 than in the composition according to example 5.
