Description

Title: Composition comprising at least one saturated fatty alcohol, at least one anionic surfactant, at least one non-silicone oil, and at least one silicon-free filler

Technical field

The present invention relates to a composition, preferably a cosmetic composition, in the form of an oil-in-water emulsion, comprising at least one saturated C16-C22 fatty alcohol; at least one anionic surfactant comprising at least one C16-C22 hydrocarbon-based chain; at least one non-silicone oil, and at least one silicon-free filler, and to the use of said composition in the cosmetics and dermatological fields, in particular for caring for or treating keratin materials.

Prior art

The type of particular galenic form targeted by the present invention, namely of the oil-in- water emulsion type requiring in particular the presence of at least one saturated C16-C22 fatty alcohol and at least one anionic surfactant comprising at least one C16-C22 hydrocarbon-based chain, makes it possible to convey active agents while providing advantageous sensory properties appreciated by users when applied to keratin materials. Compositions of the oil-in-water emulsion type requiring in particular the presence of at least one saturated C16-C22 fatty alcohol and at least one anionic surfactant comprising at least one C16-C22 hydrocarbon-based chain are described in particular in WO2018108878 and W02020002538.

However, these compositions achieve very particular aims. Their purpose is notably, respectively, to mask skin imperfections, moisturize the skin and/or treat the signs of skin ageing, in particular the appearance of fine lines and deep wrinkles, which in particular increase with age.

“Keratin materials” notably means the skin, the scalp, keratin fibres such as the eyelashes, the eyebrows, head hair, bodily hair, the nails, and mucous membranes such as the lips, and more particularly the skin (body, face, neck, area around the eyes, eyelids).

However, it is sometimes difficult to reconcile the requirements in terms of sensory property, texture and stability. In particular, it is desirable to have available compositions capable of retaining the same viscosity over time, in particular a viscosity which does not increase over time or which does not decrease over time.

Disclosure of the invention

The aim of the present invention is to solve the abovementioned technical problems.

In the light of the above, it is thus clear that there remains a need to have available compositions having advantageous sensory properties, and in particular good emollience during and after application, low soaping, which are greasy (that is to say not or barely rough) and glossy and/or satiny in terms of skin finish, while retaining a satisfactory stability, in particular a stability evaluated at 1 month and/or 2 months of storage, in particular macroscopically and microscopically after two months of storage under temperature conditions ranging from 4°C to 45°C, in particular at 4°C, room temperature (generally between 20°C and 25°C), and 45°C.

Lastly, consumers are nowadays very mindful with regard to the environmental impact of the products used.

Consequently, it is still very difficult to obtain cosmetic compositions offering particular sensory properties of sensation of emollience during and after application, of a non-rough and glossy and/or satiny skin finish, of low soaping, while maintaining a good stability over time, and with the lowest possible environmental impact.

Summary of the invention

Thus, according to a first aspect, the present invention relates to a composition, preferably a cosmetic composition, in the form of an oil-in-water emulsion, in which an oily phase is dispersed in an aqueous phase, comprising:

(a) at least one saturated C16-C22, preferably C16-C18, fatty alcohol;

(b) at least one anionic surfactant comprising at least one C16-C22, preferably C16-C18, hydrocarbon-based chain;

(c) at least one non-silicone oil, and

(d) at least one silicon-free filler.

For the purposes of the present invention, the expression "free of silicone compounds" is understood to mean a composition according to the invention which comprises less than 2% by weight, preferably less than 1% by weight, relative to the total weight of the composition, and more preferentially is free (devoid) of silicone compounds.

Silicone compounds (also called silicones) are understood to mean any silicone compounds capable of being used in the cosmetics and/or dermatological fields, that is to say inorganic compounds consisting at least of a mixture of silicon and oxygen, including in particular silicone oils, silicone surfactants, dimethylsiloxane polymers, volatile or functionalized silicones, silicone elastomers, silicone resins, phenyl silicones or aminosilicones.

As illustrated in the examples below, the Applicant has discovered, surprisingly, that it is possible to obtain compositions having advantageous sensory properties, and in particular good emollience during and after application, low soaping, which are greasy (that is to say not or barely rough) and glossy and/or satiny in terms of skin finish, while retaining a satisfactory stability over time.

Examples MATERIALS AND METHODS

Stability measurement

The stability of the compositions may be evaluated according to the following protocol.

The properties of the composition to be tested are evaluated immediately after its preparation and 24 hours later.

The composition to be tested is then stored for 2 months at various temperatures: at room temperature or “RT” (about 25°C), at 4°C and at 45°C. The temperature may be regulated using an oven, for example of the Bio Concept brand from Firlabo.

The properties are evaluated after 1 month and 2 months of storage under the conditions described above.

The properties evaluated are:

- the pH of the composition, measured using a pH-meter;

- the viscosity of the composition, measured with a viscometer, for example a Rheomat RM 100 viscometer from Lamy Rheology according to the CID-012-02 method;

- the appearance of the composition, in particular its microscopic appearance evaluated by observation of the composition under an optical microscope between slide and coverslip, at X10 or even X100 magnification;

- the colour and odour of the composition; and

Phenomena associated with destabilization of the composition will be observed, such as the appearance of creaming, coalescence, sedimentation, flocculation, the formation of a film on the surface, mottling, etc.

The closer the properties of the composition after 1 month and/or 2 months of storage remain to those initially measured at 24h at 25°C, the more the composition can be considered as remaining stable.

In particular, if the composition remains smooth and homogeneous, with no destabilization phenomena and with no change in colour or odour, then it is considered to be stable.

EXAMPLE 1

A composition according to the invention (II) and a composition outside the invention (Cl), in particular not comprising any silicon-free filler in accordance with the present invention, were prepared. These compositions, in the form of oil-in-water emulsions, comprise the compounds detailed in Table 1 below, in contents expressed as weight percentages relative to the total weight of the composition.

[Table 1]

In a tank, the components of phase A are heated to 75°C until a homogeneous medium is obtained by paddle stirring without turbomixing. Phase A is turbomixed at 75 °C for 10 minutes (3500 rpm). The components of phase B, heated to 75°C with magnetic stirring, are added to this heated mixture, while turbomixing for 10 minutes (3500 rpm). Glycerol is added to this mixture and the resulting mixture is cooled to 40°C with stirring (3500 rpm) and under vacuum. The components of phase D are then added with stirring and under vacuum, followed by the components of the other phases.

Finally, a final homogenization phase is performed down to a temperature of 30°C, with continued stirring and under vacuum, the turbomixing being reduced if necessary.

EXAMPLE 2

Results

The stability and the sensory effect of compositions II and Cl were evaluated. The stability results are reported in Table 2 below.

[Table 2]

In conclusion, only the composition according to the invention II is stable after 2 months, whether at 4°C, at room temperature or at 45°C. Specifically, it is compliant in terms of appearance, colour, odour, viscosity and pH.

After 1 month, the composition outside the invention Cl comprising silica silylate instead of lauroyllysine is thicker (compact cream) whereas the composition according to the invention is more supple.

In addition, after 2 months, the composition outside the invention Cl exhibits non- compliance in the microscopic appearance (strong anisotropy observed).

As regards the sensory evaluation, a panel of 10 experts took part in this study on the basis of a tactile and visual evaluation. The compositions were applied to the back of the hand.

The composition II according to the invention was found to provide a good emollient effect and a good greasy effect during application to the skin and in terms of the skin finish (i.e. not rough) compared to the composition outside the invention Cl, which is drier during and after application.

In addition, composition II according to the invention is described as glossy and/or satiny compared to the composition outside the invention Cl, which has a matte finish.

The presence of a silicon-free filler such as lauroyllysine in a composition according to the invention is therefore advantageous compared with the sole presence in the comparative composition of a silicon-containing filler such as silica silylate.

EXAMPLE 3

Compositions according to the invention (12) and (13) were prepared. These compositions, in the form of oil-in-water emulsions, comprise the compounds detailed in Table 3 below, in contents expressed as weight percentages relative to the total weight of the composition. [Table 3]

Preparation protocol

The same protocol as that used in Example 1 is used in this example. The compositions (12) and (13) exhibit good emollience during and after application, and are greasy (that is to say not or barely rough) and glossy and/or satiny in terms of skin finish.
