[0215] (Absorbance)

[0216] The penetration test experiments were carried out in a Franz diffusion cell (Hanson) with a Strat-M membrane (Millipore, diameter of 15 mm). This equipment consisted of a donor part and a receiver part, with the Strat-M membrane sandwiched between the donor and receiver parts. The receiver part with a predetermined volume was filled with a receiver solution (0.25 wt% Tween 80 / deionized water) maintained at a temperature of 32 °C, which was continuously stirred with a small magnetic bar. Each of the compositions according to Examples 1 to 6 and Comparative Examples 1 to 9 was spread with a spatula onto the membrane of the donor part in an amount of 30 mg / cm2. After 5 hours, 200 µl of receiver solution was removed from the receiver part, while supplying the same amount of a new receiver solution to the receiver part to maintain the same penetration conditions.

[0217] The amount of oligosaccharides in the receptor solution was determined using a phenol sulfuric acid method: 150 µl of the collected receptor solution was mixed with 750 µl of sulfuric acid for 15 minutes at 90 °C and then with 150 µl of a 5% by weight phenol solution for 5 minutes at room temperature (25 °C). The oligosaccharides were converted into a brown substance composed of a UV-absorbing chromophore. The UV absorption at 400 nm of the reacted receptor solution was measured using a spectrophotometer. The UV absorption was an indication of the amount of oligosaccharides in the receptor solution.

[0218] The results are shown in the row titled “Absorbance (400 nm)” in Tables 1 and 2.

[0219] (Summary)

[0220] Comparison of Examples 1 to 6 and Comparative Example 7 demonstrates that the use of glycols significantly enhanced the skin penetration of oligosaccharides compared to the absence of use of glycols.

[0221] Comparison of Examples 1 to 3 and Examples 4 to 6, respectively, demonstrates that the use of pentylene glycol can better enhance the skin penetration of oligosaccharides compared to the use of propylene glycol.

[0222] Comparison of Comparative Examples 1 to 6 and Comparative Example 7 demonstrates that the use of polyvalent (trivalent) alcohol or monovalent alcohol did not enhance the skin penetration of oligosaccharides compared to the absence of use of polyvalent (trivalent) alcohol or monovalent alcohol.

[0223] Comparison of Comparative Example 8 and Comparative Example 7 demonstrates that the joint use of 0.2% by weight of polyglyceryl fatty acid monoesters is insufficient to significantly enhance the skin penetration of oligosaccharides, even if glycol is used.

[0224] Comparison of Comparative Example 9 and Comparative Example 7 demonstrates that the absence of use of polyglyceryl monoesters of fatty acid did not enhance the skin penetration of oligosaccharides, even if glycol is used.

Composition, preferably cosmetic composition, and more preferably cosmetic composition for the skin, comprising: (a) at least one extract of Taraxacum Officinale; (b) at least one glycol; and (c) at least one fatty acid polyglyceryl monoester, wherein the amount of the fatty acid polyglyceryl monoester of point (c) is greater than 0.2% by weight relative to the total weight of the composition.

2. A composition according to claim 1, wherein the amount of the Taraxacum Officinale extract(s) of type (a) in the composition is from 0.01% to 5% by weight, preferably from 0.05% to 3% by weight, and more preferably from 0.1% to 1% by weight, relative to the total weight of the composition.

3. The composition of claim 1 or 2, wherein the glycol of point (b) is selected from the group consisting of propylene glycol, pentylene glycol, and mixtures thereof.

4. A composition according to any one of claims 1 to 4, wherein the fatty acid polyglyceryl monoester of point (c) comprises 2 to 4 glycerol units.

5. A composition according to any one of claims 1 to 4, wherein the composition further comprises (e) at least one oil.

6. A composition according to claim 5, wherein the oil of type (e) is selected from ester oils.

7. A composition according to any one of claims 1 to 6, wherein the composition further comprises (f) at least one anionic surfactant.

8. Composition according to claim 7, in which the anionic surfactant (f) is selected from amino acid surfactants.

10. Use of a combination of (b) at least one glycol; and (c) at least one fatty acid polyglyceryl monoester, in a composition comprising (a) at least one Taraxacum Officinale extract; in which the amount of the fatty acid polyglyceryl monoester of point (c) is greater than 0.2% by weight relative to the total weight of the composition in order to enhance the penetration of an oligosaccharide in the Taraxacum Officinale extract of point (a) into a keratinous substance such as the skin.
