Description

  The present invention relates to a composition comprising a plant extract, which is preferably in the form of a nanoemulsion or microemulsion.

  Oil-in-water (O / W) emulsions or water-in-oil (W / O) emulsions are used in the cosmetics and dermatological fields, in particular for cosmetics such as milk, cream, tonics, cosmetics or lotions. It is well known for manufacturing.

  The use of oil-in-water (O / W) emulsions in the cosmetic or dermatological field is a known practice. These emulsions, which are composed of an oil phase (or lipophilic phase) dispersed in an aqueous phase, have an outer aqueous phase and are therefore products that are comfortable to use because of the fresh sensation they provide. is there. However, they have the disadvantage that they lack considerable stability when too much oil is present. Now, in some applications, it is advantageous to have a large amount of oil because the oil provides comfort and nourishment to the skin, and these oils have makeup removal properties This is because makeup can also be removed from the skin.

  Moreover, it is advantageous to have a fine emulsion, i.e. an emulsion in which the oil phase is in the form of very small droplets, i.e. in the form of droplets with a dimension of less than 4 μm, because This is because such emulsions have a pleasant cosmetic feel and are generally more stable than coarse emulsions.

  In particular, fine emulsions such as O / W nanoemulsions or microemulsions are particularly attractive in cosmetics due to their transparent or slightly translucent appearance.

For example, JP-A-H09-110635 discloses a fine emulsion formed using a combination of polyglyceryl fatty acid ester and C ₁₀ -C ₂₂ 2-hydroxy fatty acid as a surfactant. In addition, JP-A-H11-71256 discloses a fine emulsion formed using a combination of polyglyceryl fatty acid ester and betaine.

  In industry, especially in the cosmetic industry, there is a great interest in developing products that contain ingredients derived from natural plants.

  However, compositions containing plant extracts, and in particular cosmetic compositions, tend to be unstable over time because plant extracts can affect the stability of the composition. This is because various substances are typically contained. In particular, when the plant extract is formulated into a fine emulsion such as a nanoemulsion or microemulsion, the stability of the emulsion and the transparent or slightly translucent appearance of the emulsion may be impaired.

(Example 1 and Comparative Examples 1 and 2)
The following compositions according to Example 1 and Comparative Examples 1 and 2 shown in Table 1 were prepared by mixing the ingredients shown in Table 1 as follows: (1) Mixing ingredients for the oil phase and mixing them Heat to about 75 ° C to form an oil phase, (2) mix the ingredients for the aqueous phase and heat them to about 75 ° C to form the aqueous phase, (3) the aqueous phase to the oily phase And then mixing them to obtain an O / W emulsion, (4) after completion of emulsification, the emulsion is cooled to about 60 ° C. and a thickening phase is added, (5) then the emulsion is about 25 ° C. And then add the natural plant extract phase and pH adjuster. The numerical values of the amounts of components shown in Table 1 are all based on “mass%” as an active raw material.

[Evaluation]
(Appearance, stability and turbidity)
Example 1 and Comparative Examples 1 and 2 were placed at room temperature (25 ° C.) for 24 hours. Next, the appearance of each emulsion was visually observed. Turbidity was also determined by measuring each emulsion using a 2100Q (HACH) equipped with a round cell (diameter 25 mm x height 60 mm) and a tungsten bulb.

Preparation of emulsions according to Example 1 and Comparative Examples 1 and 2 After the above visual observation and turbidity measurement after 24 hours, the emulsions were further placed at room temperature (25 ° C) for 1 month after preparation, and each emulsion The stability criteria for the following criteria:
Good stability: Transparent or translucent (turbidity is less than 200 NTU)
Poor: It was visually determined according to the white appearance, and the turbidity was measured as described above. These results are shown in Table 2.

  As is apparent from the above results, the emulsion according to Example 1 is stable over a long period of time, and due to the presence of two anionic surfactants combined with oil and polyglyceryl fatty acid ester, the emulsion Despite containing plant extract, its transparent appearance was maintained for 1 month. On the other hand, the emulsions according to Comparative Examples 1 and 2 were less stable due to the presence of a single anionic surfactant in which the oil and polyglyceryl fatty acid ester were combined, and the plant extract.
