Definitions
- the present invention relates to a cosmetic composition in the form of a nano- or micro-emulsion.
- Microemulsions oil in water, water in oil or bicontinuous have been developed these last years as an alternative of cleansing oils very much appreciated for their excellent efficacy on foundation and waterproof mascara.
- the advantage of nano- or micro- emulsion is to present sometimes better rinsibility for usually same make-up removal efficacy.
- the cost of the nano- or micro-emulsions can be reduced because of their lower oil content.
- US2006/0078525 discloses some microemulsions.
- US2007/011663, JP-A-2010-222323, JP-A-2006-241151, EP-A-1952795, JP-2010-280664, and JP-2010-280643 disclose some types of emulsions.
- microemulsions are not all equivalent in terms of cosmeticity - efficacy and rinsibility - tolerance for skin and eyes, and stability.
- An objective of the present invention is to provide a stable cosmetic, optionally cleansing, composition in the form of a nano- or micro-emulsion with transparent or slightly translucent, preferably transparent, aspect of the emulsion.
- Another objective of the present invention is to provide a cosmetic cleansing composition in the form of a nano- or micro-emulsion with good cosmetic properties such as cleansing and rinsing properties, and possibly less skin and eyes discomfort feeling.
- a cosmetic composition in the form of a nano- or micro-emulsion comprising:
- the total amount of the PGFE surfactants ((b) + (c)) in the cosmetic composition according to the present invention may be below 15% by weight relative to the total weight of the composition.
- the (a) oil may be selected from the group consisting of oils of plant or animal origin, synthetic oils, and hydrocarbon oils.
- the (a) oil may be chosen from hydrocarbon oils which are in the form of a liquid at a room temperature, and most preferably among ester oil, alkane oil, and ether oil. It may be preferable that the (a) oil be chosen from oils with molecular weight below 600 g/mol.
- the amount of the (a) oil may range from lOto 40% by weight, preferably from 15to 35% by weight, and more preferably from 20 to 30% by weight, relative to the total weight of the composition.
- the (b) first (poly)glyceryl fatty acid ester surfactant may have an HLB value of from 8.0 to 13, preferably from 9.0 to 13, and more preferably from 10.0 to 13.0. It is preferable that the (b) first (poly)glyceryl fatty acid ester surfactant be chosen from polyglyceryl monolaurate comprising 4 to 6 glycerol units, polyglyceryl mono(or di-)(iso)stearate comprising 4 to 6 glycerol units, polyglyceryl monooleate comprising 4 to 6 glycerol units, and polyglyceryl dioleate comprising 4 to 6 glycerol units.
- the amount of the (b) first (poly)glyceryl fatty acid ester surfactant may range from 0.1 to 14% by weight, preferably from 1 to 13% by weight, and more preferably from 5 to 12% by weight, relative to the total weight of the composition.
- the (c) second (poly)glyceryl fatty acid ester surfactant may have an HLB value of from 6.0 to 13.0, preferably from 6.5 to 12.0, and more preferably from 7.0 to 11.0.
- the (c) second (poly)glyceryl fatty acid ester surfactant may be chosen from (poly)glyceryl fatty acid esters with a (poly)glyceryl moiety derived from 1 or 2 glycerins, preferably glyceryl caprylate, PG-2 caprate, and a mixture thereof.
- the amount of the (c) second (poly)glyceryl fatty acid ester surfactant may range from 0.1 to 8% by weight, preferably from 0.3 to 6% by weight, and more preferably from 0.5 to 5% by weight, relative to the total weight of the composition.
- the cosmetic composition according to the present invention may further comprise at least one additional nonionic surfactant different from the above (b) or (c) and/or at least one ionic surfactant.
- the above additional nonionic surfactant may be (f) at least one
- the amount of the (f) at least one oxyalkylene-including nonionic surfactant may range from 0.1 to 25% by weight, preferably from 0.5 to 20% by weight, and more preferably from 1 to 10% by weight, relative to the total weight of the composition.
- the total amount of all the surfatants in the cosmetic composition according to the present invention may be below 15% by weight relative to the total weight of the composition.
- the weight ratio of the total amount of the surfactants to the (a) oil may be from 0.3 to 6, preferably from 0.4 to 3, and more preferably from 0.45 to 1.5.
- Polyol is preferably bivalent and trivalent, and more preferably bivalent.
- Preferred polyols are butylene glycol, glycerin, propanediol, dipropylene glycol, hexylene glycol, and PEG8.
- the amount of total polyols may be between 4% and 50%, preferably between 6% and 40%, and more preferably between 8% and 30%, relative to the total weight of the composition.
- the cosmetic composition according to the present invention may further comprise at least one thickening agent, preferably selected from associative thickeners. It is preferable that the cosmetic composition according to the present invention be in the form of an O/W emulsion, and the (a) oil be in the form of a droplet with a number average particle size of 300 nm or less, preferably from 10 ran to 150 nm.
- the cosmetic composition according to the present invention have a
- nephelometric turbidity below 150 NTU, preferably below 100 NTU, and more preferably below 50 NTU.
- the present invention also relates to a non-therapeutic process for treating the skin, the hair, mucous membranes, the nails, the eyelashes, the eyebrows and/or the scalp, characterized in that the cosmetic composition according to the present invention is applied to the skin, the hair, mucous membranes, the nails, the eyelashes, the eyebrows or the scalp.
- the present invention also relates to a use of the cosmetic composition according to the present invention, as or in care products and/or washing products and/or make-up products and/or make-up-removing products, such as cleansing products, for body and/or facial skin and/or mucous membranes and/or the scalp and/or the hair and/or the nails and/or the eyelashes and/or the eyebrows.
- the transparent or slightly translucent aspect of the cosmetic composition according to the present invention can be maintained without depending on temperature.
- the cosmetic composition according to the present invention can have good cosmetic properties such as cleansing and rinsing properties, and possibly less discomfort feeling to skin and eyes.
- the present invention is a cosmetic composition in the form of a nano- or micro-emulsion, comprising:
