OIL-DAN S-WATER EMULSION COMPRISING A FATTY ALCOHOL, ONE

ALKYLETHER POLYOXYETHYLENE, A WAX AND A POLYSACCHARIDE

The present invention relates to a composition in the form of an oil-in-water emulsion comprising, in a cosmetically acceptable medium:

A) a continuous aqueous phase, and

B) an oily phase dispersed in said aqueous phase and comprising at least one hydrocarbon oil;

C) at least one mixture consisting of:

i) at least one nonionic surfactant chosen from fatty alcohols comprising from 8 to 30 carbon atoms, and

ii) at least two oxyethylenated and / or oxypropylenated C 8-30 fatty alcohols,

D) at least one wax with a melting point of greater than 45 ° C comprising one or more C ₄ o C ₇ o ester compounds and not comprising a C ₂₀ -C 39 ester compound, in an amount ranging from 1 to 10% by weight relative to the total weight of the composition, and

E) at least one water-soluble polysaccharide;

said composition having a viscosity measured at 25 ° C. with a Rheomat RM 180 viscometer at 200 s ^-1 at ambient temperature at mobile 3 or mobile 4 after 10 min, ranging from 1200 to 8000 mPa.s.

In the field of cosmetic skin care products including deodorant and antiperspirant products, it is possible to define different categories of galenics: aerosols, sticks, creams, gels, soft solid or roll-on.

The "soft solid" compositions are a new category of products appreciated by consumers for their effectiveness and their cosmetic qualities (ease of application, dry and soft touch). They are similar to solid compositions that soften under the effect of a stress such as spreading on the surface of the skin or for example by extrusion through a perforated wall device (grid). Compositions "soft solid" by their melting texture can also be valued as a care product of human keratin materials such as skin or lips as massage products, balms or ointments, sticks for the care of the lips. They have been described in particular in application WO2012 / 084522. Because of their anhydrous texture, these formulations may appear oily, present on the skin and not very fresh. In contrast, roll-on is a range of fluid and fresh products that can sometimes be considered sticky and very slow to dry. WO2014 / 128060 describes antiperspirant compositions in the form of wax-based W / O emulsions, a water-soluble polysaccharide and a surfactant system comprising a specific fatty alcohol and an alkylpolyglucoside. However, such compositions still leave white traces after application. It therefore remains the need to produce cosmetic formulations "soft-solid" care for the skin, including deodorant and / or antiperspirant products, combining ease of application, dry touch immediate, soft, non-wetting and non-sticky and which are effective in the desired application. In particular, there is the need for "soft-solid" cosmetic compositions for skin care, especially deodorant and / or antiperspirant products, which minimize the presence of white traces after application.

The applicant has now discovered that this objective can be achieved with new emulsions forming solid-soft compositions ("soft-solid") stable storage, having both good cosmetic properties: soft touch and dry feeling immediate, freshness non-wetting, no stickiness and non-greasy touch, as well as a good efficiency in the desired application. In particular, the compositions make it possible to reduce the presence of white traces after application. This discovery is the basis of the invention.

The present invention thus relates to a composition in the form of an oil-in-water emulsion comprising, in a cosmetically acceptable medium:

A) a continuous aqueous phase, and

C) at least one mixture consisting of:

ii) at least two oxyethylenated and / or oxypropylenated C 8-30 fatty alcohols, D) at least one wax with a melting point of greater than 45 ° C comprising one or more C ₄ o C ₇ o ester compounds and not comprising a C ₂₀ -C 39 ester compound, in an amount ranging from 1 to 10% by weight relative to the total weight of the composition, and

E) at least one water-soluble polysaccharide;

The present invention also relates to a cosmetic process treatment and / or care of human keratin materials characterized in that it consists in applying to the surface of the keratin material a composition as defined above.

By way of example, the hydrophobic group may be derived from a fatty alcohol such as stearyl alcohol, dodecyl alcohol, decyl alcohol or a polyoxyalkylenated fatty alcohol such as steareth-100. It can also denote a hydrocarbon polymer such as for example polybutadiene.

The nonionic associative polymers may be chosen from:

celluloses modified with groups comprising at least one fatty chain, for example hydroxyethylcelluloses modified with groups comprising at least one fatty chain, such as alkyl groups, especially C ₈ -C ₂₂ , arylalkyl, alkylaryl, such as NATROSOL PLUS GRADE 330 CS (alkyls d ₆ ) sold by AQUALON,

celluloses modified with alkyl phenol polyalkylene glycol ether groups, such as the product AMERCELL POLYMER HM-1500 (polyethylene glycol (15) nonylphenol ether) sold by the company Amerchol,

guars such as hydroxypropyl guar, modified with groups comprising at least one fatty chain such as an alkyl chain,

inulins modified with groups comprising at least one fatty chain, such as the alkyl carbamate inulins and in particular the lauryl carbamate inulin proposed by the company Oraffi under the name INUTEC SP1, and

The associative polyurethanes are nonionic block copolymers comprising in the chain both hydrophilic sequences most often of a polyoxyethylenated nature (the polyurethanes may then be called polyurethane polyethers) and hydrophobic sequences which may be aliphatic chains alone and / or or cycloaliphatic and / or aromatic chains.

In particular, these polymers comprise at least two hydrocarbon-based lipophilic chains having from 6 to 30 carbon atoms, separated by a hydrophilic sequence, the hydrocarbon chains may be pendant chains or chains at the end of the hydrophilic sequence. In particular, it is possible that one or more pendant chains are provided. In addition, the polymer may comprise a hydrocarbon chain at one end or at both ends of a hydrophilic block.

The associative polyurethanes can be sequenced in the form of triblock or multiblock. The hydrophobic sequences may therefore be at each end of the chain (for example: hydrophilic central block triblock copolymer) or distributed at both the ends and in the chain (multiblock copolymer for example). These polymers may also be graft or star. Preferably, the associative polyurethanes are triblock copolymers whose hydrophilic sequence is a polyoxyethylenated chain comprising from 50 to 1,000 oxyethylenated groups. In general, the associative polyurethanes comprise a urethane bond between the hydrophilic sequences, hence the origin of the name. According to one embodiment, a non-ionic polyurethane associative polymer is used as gelling agent.

In addition, the transfer of white traces is evaluated according to the following protocol:

Sample preparation:

- Support preparation

Attachment of the Supplale (K638 from Beaulax) on cardboard sheets with double-sided tape, cut circles of 50mm diameter by punch or laser and then stick on a lid Cleopatra pot that will serve as support rigid when measuring.

- Preparation of the deposit

The formula to be tested is deposited in order to have 0.08 g after spreading (ie approximately 3.75 mg / cm ² , which corresponds to the 0.4 g consumed on average by the consumers per axelle and per day).

The formula is spread in a circle (20-25 turns) to the unpowdered fingerstand on the Supplale support 50mm in diameter.

It is allowed to dry 24 hours on a thermostatically controlled plate at 35 ° C.

The formula is tested in triplicate. Measurement and parameters of the tribometer (Standard Tribometer from CSM instrument):

- Mobile: flat disc diameter 14mm on which we stick standard black knitted cotton

(IFTH 120g / cm ² ) with double-sided tape (cut with a punch (0 = 14mm)).

- Software: InstrumX TRIBOX - "Tribometer Measure".

- Measurement parameters: Lathe: 1 revolution - Speed: 3.14 cm / s, Force applied: 1 N. Finally, we set the radius - RPM diameter: 7mm.

Results

Once the protocol is applied:

- The cotton discs are recovered to visually analyze the bleaching: the white traces are evaluated;

- Supplale plates are collected to analyze the deposit: the homogeneity and resistance of the deposit are evaluated.
