Definitions
- TITLE Cosmetic composition in the form of an oil-in-water nanoemulsion comprising at least one liquid fatty substance, at least one solid fatty substance and at least one cationic surfactant
- the present invention relates to a cosmetic composition in the form of an oil- in-water nanoemulsion
- a cosmetic composition in the form of an oil- in-water nanoemulsion
- at least one liquid fatty substance (i) preferably including at least one oil of triglyceride type, at least one solid fatty substance (ii), at least one particular surfactant (iii), and water (iv)
- the total content of fatty substances (i) and (ii) being greater than or equal to 40% by weight, relative to the total weight of the composition.
- the present invention also relates to a process for the cosmetic treatment of keratin materials, in particular of human keratin fibres such as the hair, in which this composition is applied to said fibres.
- the invention relates to the use of this composition for the cosmetic treatment of keratin materials, in particular of human keratin fibres such as the hair.
- compositions in the form of a nanoemulsion in particular of oil-in-water type (O/W) are well known in the cosmetics and dermatology domain, in particular for preparing cosmetic products such as lotions, creams, tonics, serums or eaux de toilette in order to be applied to the skin and/or the hair.
- O/W oil-in-water type
- Compositions in nanoemulsion form generally have a number-average oil drop (or oily globule) size of less than 100 nanometres, said oil drops being stabilized by a layer of amphiphilic molecules that can optionally form a liquid crystal phase of lamellar type, located at the oil/aqueous phase interface.
- amphiphilic molecule is intended to mean herein any molecule having a bipolar structure, i.e. including at least one hydrophobic part and at least one hydrophilic part and having the property of reducing the surface tension of water (g ⁇ 55 mN/m) and of reducing the interface tension between water and an oily phase.
- Amphiphilic molecules are for example surfactants, surface agents or emulsifiers.
- compositions in the form of a nanoemulsion offer a certain number of advantages from a cosmetic or dermatological point of view leading in particular to a uniform and effective deposit of the composition on the skin and/or hair, in particular for the hair a uniform deposit from the root to the end, while at the same time allowing satisfactory oil penetration and persistence.
- compositions in nanoemulsion form confer improved cosmetic properties on keratin materials.
- compositions in nanoemulsion form confer good disentangling, softness, feel, rinsability and suppleness properties and have a very good conditioning effect, which usually prove to be better than those obtained with the conventional emulsions and dispersions used in the cosmetics field.
- Oil-in-water type nanoemulsions are for example described in patent application FR 1 763 395.
- compositions during application to wet keratin materials, for example wet hair, sometimes transform too rapidly while going from a very structured gel to a fluid milk, which can present drawbacks, for example in terms of use qualities. More specifically, such compositions do not make it possible to guarantee a sufficiently precise application and a uniform distribution of the product on the keratin materials. In particular, it is sometimes difficult to take a handful of these compositions, to measure them out and to apply them to keratin materials, these compositions tending to run off said materials.
- composition in the form of an oil-in-water nanoemulsion comprising at least one liquid fatty substance (i), preferably including at least one oil of triglyceride type of plant or synthetic origin, at least one solid fatty substance (ii), at least one particular surfactant (iii), and water (iv), the total content of fatty substances (i) and (ii) being greater than or equal to 40% by weight, relative to the total weight of the composition makes it possible to meet the needs expressed above.
- such a composition can have an original gelled texture which does not require the addition of thickening polymers or of a gelling agent.
- a subject of the invention is thus a cosmetic composition in the form of an oil-in-water nanoemulsion comprising: (i) one or more fatty substances with a melting point of less than or equal to 25°C, preferably including one or more oils of triglyceride type of plant or synthetic origin,
- the composition according to the invention has a firm, or even gelled, texture, and an "on surface” effect, that is to say a transformation of texture during application with the sensation of a creamy and rich texture which nicely coats the hair or nicely covers the skin, even though a fluid composition is applied. That results in the appearance of a coating and a more or less strong presence of the product on the keratin materials, at the moment of application.
- This effect is directly connected to the rheological behaviour of the galenic product when it comes into contact with the wet keratin material, and thus to its level of viscosity when diluted with water.
- the moment of application thus lasts longer; it also makes it possible to facilitate the grasping and measuring out of the product, and to obtain a better localization and a better distribution of the composition on the keratin materials, in particular keratin fibres, when it is applied, while at the same time minimizing the risks of running and/or splashing, in particular into the eyes.
- the composition has improved use qualities guaranteeing both a more targeted distribution without running at the point of application and a uniform spreading on the keratin materials, in particular the keratin fibres.
- the initial composition which can be in quite a fluid form, will transform, during application to wet hair, into a creamier composition; the user will have the sensation of having more material to be distributed on the hair, the composition will not immediately melt away during application.
- the composition according to the invention makes it possible to confer on the keratin fibres improved cosmetic properties, in particular in terms of suppleness, feel, softness, disentangling, and also good rinsability properties.
- composition according to the invention is stable with respect to storage over time, both at ambient temperature (25°C) and at higher temperatures, in particular at 45°C.
- stable with respect to storage over time is intended to mean that the following physical characteristics of the composition vary little, or even not at all, over time: oil globule size, appearance, pH, rheology (viscosity, consistency).
- the composition does not give rise to any phase-separation or exudation phenomena over time, and at the intended storage temperature.
- the invention also relates to a process for the cosmetic treatment of keratin materials, in particular of human keratin fibres such as the hair, in which the composition according to the invention is applied to said materials, preferably fibres.
- the invention relates to the use of said composition for the cosmetic treatment of keratin materials, in particular of human keratin fibres such as the hair.
