Description

-1-- 2495468

  The subject of the present invention is a novel oil based on a mixture of vegetable oils that can be used in cosmetics

  as well as cosmetic compositions containing it.

  The oils generally used in cosmetics or "cosmetic oils" are fatty products that are liquid at room temperature.

  ambient and low volatility.

  These oils can be of very varied origin and in particular vegetable or animal oils, mineral oils

or synthetic oils.

  These oils according to their origin are likely to

  leave on the skin a film more or less fat. We consider -

  usually when the film is particularly greasy the oil is non-penetrating and prevents the skin from dehydrating

because of its occlusive properties.

  Thus vaseline oil leaves on the skin a very greasy film having the disadvantage both to cause excess moisture of the skin and give it a sticky or sticky touch and a shiny aspect considered particularly unattractive. Other so-called penetrating oils do not exhibit the particularly fatty nature of liquid petrolatum and

  leave a non-greasy film on the skin but nevertheless have the incon-

  to avoid satisfactorily preventing dehydration

tation of the skin.

  The vegetable oil mixture according to the invention makes it possible to remedy the drawbacks mentioned above insofar as it does not leave on the skin a film of too shiny appearance

which can harm the aesthetics.

  Moreover, the film left on the skin provides a protective effect vis-à-vis external aggressions such as

  the sun, the wind and the cold, while preventing the dehy-

  dratation of the skin, is not sufficiently occlusive for

  cause excess moisture from it.

  Because of its properties, namely formation of a low-fat and low-occlusive film, the mixture according to the invention is particularly applicable in certain cosmetic compositions containing a high proportion of oils such as

  for example, solar products, and especially

  lar. The subject of the present invention is a new oil 40

-2- 2495468

  cosmetics based on vegetable oils, this oil being

  by a mixture of hazelnut oil and another vegetable oil taken from the group consisting of pine oil

umbrella and peanut oil.

  These oils have already been proposed in cosmetics but

  their particularly binary mixtures have never been recommended.

  It has been found by many tests that only mixtures containing a certain proportion of hazelnut oil are likely to lead to the cosmetic properties

sought.

  Indeed, peanut oil and pine oil mixtures used in different proportions have proved to be poorly

  cosmetically satisfactory.

  In addition, these tests also made it possible

  conclude that it was desirable to use these oil blends

  in relatively well-defined proportions.

  As it is the mixture of hazelnut oil and pine tree oil or mixture of hazelnut oil and peanut oil, it is preferable to use these mixtures

  in a ratio by weight of between 20:80 and 80:20.

  According to the invention the hazelnut oil, the parasol pine oil and the peanut oil should preferably have the following characteristics: Hazelnut oil: - specific gravity 0.911-0.917 - refractive index at 20 ° C. 1,469 -1,472 - saponification number 187-197 - 83-103 iodine number - unsaponifiable 0,3-0,7% Parasol pine oil: - specific gravity 0,920-0,932 - refractive index at 40 ° C 1,467-1,469 - saponification number 192-198 - iodine number 118-125 - unsaponifiable 0,5-2% Peanut oil: - specific gravity 0,914-0,920 - refractive index at 200C 1,470-1,474 - saponification number 188-196 - iodine value 85108 - unsaponifiable 0.6-1%

  The cosmetic compositions in which the new

  true cosmetic oil as defined above can be

  employed, are in general all the cos-

metics containing oils.

  Preferably these compositions contain at least 10%

  cosmetic oil according to the invention.

  Among these compositions, mention may be made of those which are in the form of fluid emulsions (milks), lotions,

  in the form of more consistent emulsions such as creams.

  These compositions are, for example, milks or emollient creams, milks or creams for the care of

  hands, body or face, creams or milks

  lotion, foundation bases, milks or creams

  sunscreens, artificial tanning milks or creams, milks or creams for perspiration, creams or foams for shaving, pre-shave lotions or milks

  or creams for the skin care of babies.

  The cosmetic oil according to the invention can also be used to make makeup compositions such as, for example, lip sticks for either coloring (lipsticks) or preventing chapping, compositions for making up the eyes. , and makeup for the face. The cosmetic compositions according to the present application in the form of solutions are in particular sunscreen oils, that is to say containing, in addition to the cosmetic oil, an ultraviolet-absorbing sunscreen, hand oils,

  oils for the body, oils for pre-resealing or after-

shaving, bath oils.

  Generally in these compositions in the form of solutions the proportion of cosmetic oil according to the invention

  varies between 10 and 99.9% of the total weight of the composition.

  In the cosmetic compositions of the invention

  form of emulsions or lotions the cosmetic oil is gener-

  usually present in a proportion of 10 to 60% by weight

  relative to the total weight of the composition.

  In makeup compositions, the proportion of the cosmetic oil according to the invention varies from 10 to 80% of the

total weight of the composition.

  The compositions according to the invention generally contain

-4- 2495468

  other ingredients such as, for example, preserving agents, antioxidants, perfumes,

dyes, etc.

  In order to demonstrate the good properties of the cosmetic oil according to the invention, the following experiments were carried out:

  It was applied to the skin of the back of the hand of

  volunteers a same amount of one of the following oils or oil mixtures: 1) Hazelnut oil 2) Parasol pine oil 3) - Peanut oil 4) Hazelnut oil 20% / Parasol pine oil 80 %) 40% hazelnut oil / 60% pine tree oil 6) 50% hazelnut oil / 50% pine tree oil 7) 60% hazelnut oil / 40% pine tree oil 8) 80% hazelnut oil 20% pine nut oil 20% hazelnut oil / 80% peanut oil 40% hazelnut oil / 60% peanut oil 11) 50% hazelnut oil / 50% peanut oil 12 ) 60% hazelnut oil / 40% peanut oil

  13) 80% hazelnut oil / 20% peanut oil.

  After the application, those people who do not know the origin of the different oils applied attributed to them according to certain criteria a score between 0 and 10, a high score corresponding to a rapid penetration, a

  not shiny appearance and a little fat touch.

  These criteria were as follows: 1) Penetration rate: fast, low, very low, 2) Appearance of the skin after application: very shiny, shiny, not shiny, 3) Touch after application: very oily, oily, little

fat. -

  The average of the scores obtained is shown in the following table: -5The variance analysis and the Student test applied to this experiment show that the difference in the rating between

  oils 1, 2 and 3 and the oil mixtures 4 to 13 according to the invention.

This is significant.

  Several examples of compositions will now be given by way of illustration and without any limiting character.
