Description

Title of the invention: SKINCARE AND / OR MAKE-UP COMPOSITION OF KERATINOUS MATERIALS Technical field

[0001] The present invention relates to a cosmetic composition. In particular, the present invention relates to a composition for the care and / or makeup of keratinous materials. The present invention further relates to a non-therapeutic method for the care and / or makeup of keratinous materials. STATE OF THE ART

[0002] The development of formulations dedicated to the care and / or makeup of the skin and / or lips is ongoing.

[0003] A matte appearance like cashmere in a cosmetic composition is preferable because its use could provide a more pleasant sensation.

[0004] It is desirable that a cosmetic composition have a good texture, such as a "cushioning" sensation during application. The "cushioning sensation" here means that the fingers feel the presence of the cosmetic composition, which could be felt as if there were a cushion between the fingers.

[0005] However, it is difficult for a conventional cosmetic composition to simultaneously satisfy the above requirements.

[0006] Consequently, there is always a need to formulate a composition, preferably for the care and / or makeup of keratinous materials, particularly skin, that has a matte appearance and / or can provide a cushioning sensation. Summary of the invention

[0007] The inventors have now discovered that it is possible to formulate such compositions having the desired properties as described above.

[0008] More specifically, the inventors discovered that it is possible to formulate skincare and / or makeup compositions of keratinous materials, in particular of the skin, which have a matte appearance and / or can deliver a cushioning sensation.

[0009] Consequently, according to a first aspect, the present invention relates to a composition, preferably for the care and / or makeup of keratinous materials, comprising the following components: i. at least 0.1% by weight of at least one starch grafted with an acrylic polymer, relative to the total weight of the composition; ii. at least one hydroxyalkyl-modified starch; and iii. at least one alkyl polyglucoside.

[0010] The inventors have discovered that the composition according to the present invention has a matte appearance and / or delivers a cushioning feel.

[0011] According to a second aspect, the present invention relates to a non-therapeutic method for the care and / or makeup of keratinous materials, comprising the application of the composition according to the present invention on the keratinous materials.

[0012] Other subjects and features, aspects and advantages of the present invention will be presented in the following description and, in part, will emerge from the description, or can be learned through practice of the present invention. DETAILED DESCRIPTION OF THE INVENTION

Hydroxyalkyl modified starch

[0034] According to the first aspect, the composition of the present invention comprises at least one hydroxyalkyl modified starch.

[0035] Hydroxyalkyl modified starch is a modified starch in which the hydroxyl group is linked via an alkyl group, such that there are 2 to 10 carbon atoms in the alkyl group. The position of the hydroxyl group is not critical and can be in the alpha to omega positions. Hydroxyalkyl modified starch can also contain more than one hydroxyl group per alkyl group. In some suitable embodiments, the degree of substitution of the hydroxyalkylation is approximately 0.08 to 0.3. The degree of substitution is the average number of substituted OH groups in the starch molecule per anhydroglucose unit. The hydroxyalkylation of a starch can be induced by reacting a native starch with alkylene oxides having the appropriate number of carbon atoms, including, but not limited to, hydroxypropylation by reacting the starch with propylene oxide.

[0036] Preferably, the hydroxyalkyl in the hydroxyalkyl-modified starch is a C2-C6 hydroxyalkyl.

[0037] Preferably, the hydroxyalkyl modified starch is chosen from hydroxyethyl starch, hydroxypropyl starch, hydroxyethyl starch phosphate, hydroxypropyl starch phosphate and one of their mixtures.

[0038] More preferably, the hydroxyalkyl modified starch is chosen from hydroxyethyl starch phosphate, hydroxypropyl starch phosphate, and one of their mixtures.

[0039] Hydroxyalkyl modified starch can be pregelatinized. Pregelatinization and techniques for achieving pregelatinization are known in the art and disclosed, for example, in US patents Nos. 4,465,702, 5,037,929, 5,131,953 and 5,149,799. See also Chapter XXIL, "Production and Use of Pregelatinized Starch," in Starch: Chemistry and Technology, Vol. III - Industrial Aspects, R.L. Whistler and E.F. Paschall, Editors, Academy Press, New York, 1967.

[0040] As used herein, the term "pregelatinized" is intended to refer to swollen starch particles that have lost their birefringence and / or Maltese crosses under polarized light. These pregelatinized starch derivatives are substantially soluble in cold water without cooking.

[0041] In this context, the term "soluble" does not necessarily mean the formation of a true molecular solution, but can also mean a colloidal dispersion.

[0042] In a preferred embodiment, the hydroxyalkyl modified starch is completely pregelatinized.

[0043] In a preferred embodiment, the starch molecules used in the present invention may be unmodified or chemically or physically modified. Examples of unmodified starches include unmodified corn starches (INCI name: Zea mays starch), for example, products sold under the trade name Farmal CS®, in particular the Farmal CS 3650® product from Corn Products International. Examples also include unmodified rice starches (INCI name: Oryza sativa (rice) starch), for example, the Remy DR I® product sold by Beneo-Remy.

[0044] In a preferred embodiment, the hydroxyalkyl modified starch of the present invention uses starches modified by crosslinking with functional agents capable of reacting with the hydroxyl groups of starch molecules, which thus bind together (for example with glyceryl and / or phosphate groups).

[0045] Mono-starch phosphates (of the type St-O-PO-(OX)2), distarch phosphates (of the type St-O-PO-(OX)-O-St), or even tri-starch phosphates (of the type St-O-PO-(O-St)2), or mixtures thereof, can be obtained, in particular, by crosslinking with phosphorus compounds. X designates, in particular, alkali metals (for example, sodium or potassium), alkaline earth metals (for example, calcium or magnesium), ammonium salts, amine salts, for example, those of monoethanolamine, diethanolamine, triethanolamine, 3-amino-1,2- Propanediol, or ammonium salts derived from basic amino acids, such as lysine, arginine, sarcosine, ornithine, or citrulline. Phosphorus compounds may include, for example, sodium tripolyphosphate, sodium orthophosphate, phosphorus oxychloride, or sodium trimetaphosphate.

[0046] Preferably, the hydroxyalkyl modified starch consists of distarch phosphates or distarch phosphate-rich compounds, in particular distarch phosphate hydroxypropyl ethers bearing the INCI name: Hydroxypropyl Starch Phosphate, for example the products sold under the trade names Farinex VA70 C or Farmal MS 689® from Avebe Stadex; the products sold under the trade names Structure BTC®, Structure HVS®, Structure XL® or Structure Zea® from National Starch (corn distarch phosphate).

[0047] More preferably, the hydroxyalkyl modified starch made from starch will be chosen from unmodified maize starches, unmodified rice starches and maize distarch phosphates, or mixtures thereof; even more preferably, the starch will be chosen from maize distarch phosphates.

Composition evaluation

[0135] The matte appearance and cushion-like feel delivered by the compositions of examples 1 and 2 of the invention and comparative examples 1 to 6 were evaluated. Matte finish

[0136] The matte appearance was evaluated as follows. Each composition of Examples 1 and 2 of the invention and of comparative examples 1 to 6 was coated onto a substrate to form a film with a thickness of 25 µm. The substrate bearing the film was placed in an oven at 37 °C for 10 minutes, and then the film was measured with a BYK haze-gard i_4775 hazemeter.

[0137] The higher the haze percentage, the higher the matte finish of the composition under test. For the purposes of the present invention, a haze percentage greater than 10% is acceptable. Cushioned feel

[0138] The cushioning sensation delivered by each of the compositions of Examples 1 and 2 of the invention and comparative examples 1 to 6 was evaluated by 10 skin experts during a blind test.

[0139] In order to evaluate the cushioning sensation (also called airy feel), the experts applied 0.3 g of each composition under test to the skin. The degree of cushioning sensation delivered by the composition under test was then rated on a scale of 1 to 5 according to the following standard, and the ratings were then averaged for each composition.

[0140] 1: means a very slight cushioning sensation,

[0141] 2: means a slight cushioning sensation,

[0142] 3: means a moderate cushioning sensation,

[0143] 4: means a moderate to strong cushioning sensation,

[0144] 5: means a very strong cushioning sensation.

[0145] During the test, dimethicone (and) polysilicone-11 were used as the standard sample and the cushioning sensation delivered was thus given a score of 5.

[0146] In the context of the present invention, the higher the value of the note, the better the sensation of transformation.

[0147] The results of the veil of each composition of examples 1 and 2 of the invention and of comparative examples 1 to 6 and of the cushion sensation thus delivered are summarized in Table 3.
