ft I COMPLETE SPECJFICATION FOR THE INVENTION ENTITLED: Cosmetic composition for improving the aesthetic appearance of the skin based on multivitamiin mixtures The following statement is a full description of this invention, including the best method of performing it known to me/us:- '4 r la- The present invention relates to a cosmetic composition for improving the aesthetic appearance of the skin, especially of the face, based on multivitamin combinations.

It is known that certain balanced combinations of vitamins make it possible to treat people suffering a deficiency in their general condition due to physical or mental 1 0 fatigue, to overexertion or to an imbalanced diet. Furtherr more, such vitamin-based treatments are particularly recommended during periods of growth or pregnancy and during

S.

So convalescence.

*94 These vitamin mixtures, which can also be combined I' 15 with mineral salts and oligo-elements, essentially contain the following vitamins, in therapeutically active doses: A, D2, Bl, B2, B5, B6, C and E as well as nicotinic acid (vita- 9*44 P O min PP) and biotin (vitamin H).

It is also known, from numerous scientific studies, that the skin is a tissue which is particularly sensitive to °o nutrition lacking in vitamins. Deficiency in vitamins from the B group, especially vitamins Bl, B2 and B6 as well as deficiency in vitamins C and A cause skin disorders which manifest themselves as a coarse look of the skin, an absence 25 of elasticity and lack of glow.

In order to overcome these symptoms, cosmetic compositions based on certain lipid-soluble and water-soluble vitamins have been proposed inasmuch as these were sufficiently stable.

Pantothenic acid (vitamin B5) has also been proposed as having a beneficial effect on the skin, although there is no sure proof of penetration through the epidermis.

These vitamin supplements which are either taken orally or applied locally are generally not sufficiently balanced as regards the different vitamins, so that treatments based on multivitamin compositions do not make it possible to improve the aesthetic appearance of the skin,

After extensive studies carried out in this field, it was found quite surprisingly and unexpectedly that particularly favourable results could be obtained, as far as the aesthetic appearance of the skin was concerned, by using suitable mixtures of vitamins in a cosmetic carrier.

The results obtained have in fact made it possible to show that the multivitamin compositions according to the invention improved the appearance of the skin in a very sig- 10 nificant manner, the skin being smoother, softer and more S. supple to touch.

Furthermore, it was found that the persons thus treated all had a face which had more glow to it and that in o.s addition the skin displayed a better resistance to outside 15 influences.

Therefore, the object of the present invention is a as0 0cosmetic composition for improving the aesthetic appearance S of the skin, characterized by the fact that it contains, in o a suitable cosmetic vehicle, a mixture of vitamins in the S 20 following proportions by weight based on the total weight of the composition:

'I.

as.

a soC *0 C a a a a Vitamin E between 0.3 and 6 Vitamin A between 0.005 and 0.5 Vitamin B2: between 0.001 and 0.01% 25 Vitamin B5: between 0.5 and 3 Vitamin H between 0.01 and 0.05%.

Vitamin E or L-tocopherol, preferably in the form of -tocopherol acetate, is preferably contained in the composition in a quantity of between 1.5 and 5% by weight.

Vitamin A or retinol is preferably contained in the composition in a quantity of between 0.15 and 0.35% by weight.

Vitamin B2 or riboflavin, in the form of its sodium salt of the 5'-phosphate derivative, is preferably contained in the composition in a quantity of between0.002 and 0.008% by weight.

Vitamin B5 or pantothenic acid, preferably in the form 3 of calcium or sodium D-pantothenate, is preferably contained in the composition in a quantity of between 1 and 2% by weight.

Vitamin H or biotin is preferably contained in the composition in a quantity of between 0.015 and 0.03% by weight.

These different percentages are expressed here based on the total weight of the cosmetic composition.

The studies which have been carried out have made it possible to highlight the importance of these different vitamins with regard to the desired cosmetic effect.

oThe cosmetic composition may come in various forms o^ allowing easy application of the composition to the skin, 8 9 S"'a especially on the face.

15 Thus, it may be, for example, a cream, a milk, a serum or an emulsion of the oil-in-water or the water-in-oil type.

Of course, the vehicle of the composition should not have any detrimental effect on the stability of the vitamin S° mixture.

20 The emulsifying agents in these compositions generally make up between 1 and 20% and preferably between 2 and 12% by weight based on the total weight of the composition.

Among the various emulsifiers which can be used may be e*8 mentioned, in particular: 25 esters of polyoxyethylenated or polyglycerolated fatty acids, oxyethylenated or polyglycerolated fatty alcohols such as, for example, oleyl alcohol polyoxyethylenated with moles of ethylene oxide, stearyl alcohol polyoxyethylenated with 10 to 20 moles of ethylene oxide, oleyl alcohol polyglycerolated with 4 moles of glycerol and synthetic fatty alcohols having from 9 to 15 carbon atoms polyoxyethylenated with 5 to 10 moles of ethylene oxide, alkyl sulfates which may or may not be oxyethylenated such as sodium lauryl sulfate, ammonium lauryl sulfate, sodium cetyl stearyl sulfate, triethanolamine cetyl stearyl sulfate, monoethanolamine lauryl sulfate, oxyethylenated f 4 sodium laurylether sulfate (with 2.2 moles of ethylene oxide, for example) and oxyethylenated monoethanolamine laurylether sulfate (with 2.2 moles of ethylene oxide, for example), and soaps such as triethanolamine stearate.

The emulsifying system consisting of magnesium lanolate and alcohol of lanolin and/or hydrogenated lanolin may also be mentioned.

The water phase of the emulsions may optionally contain jellifying agents such as, for example, hydroxypropyl methylcellulose. The oil phase, consisting of at least one Stoil and optionally of at least one wax, varies between approximately 8 and 50% by weight based on the total weight Sf t of the composition.

Among the fatty products constituting the fatty phase S 15 of these compositions may be mentioned: hydrocarbonated oils such as paraffin oil, purcellin oil, perhydrosqualene and solutions of microcrystalline waxes in oils, *o animal or vegetable oils such as oil of sweet almond, avocado oil, calophyllum oil, lanolin, castor oil, horse oil, pig oil, sesame oil, olive oil, jojoba oil, oil of karite, hoplostethus oil, sunflower oil, n.d, mineral oils of which the initial destillation point under atmospheric pressure is approximately 250°C and the 25 final point is about 4100C, saturated or unsaturated esters such as alkyl myristates, for example those of isopropyl, butyl or cetyl, hexadecyl stearate, ethyl or isopropyl palmitates, triglycerides of octanoic and decanoic acid and cetyl ricinoleate.

The cosmetic compositions according to the invention may also contain vitamins other than those mentioned, in particular vitamin F (essential fatty acids), vitamin D, vitamin B6, or folic acid, as well as other substances to maintain and improve the properties of the skin such as, for example, moisturizers, revitalizing agents and protein derivatives.

-X a~o-I-~ 5 According to a particular embodiment, the cosmetic composition according to the invention contains between 0.005 and 0.025% of folic acid, and preferably between 0.0075 and 0.015%.

Some of the vitamins of the composition may be incorporated in microdispersions of the liposome type.

SIn addition, the composition may also contain colouring agents, perfumes, sun filters, anti-oxidants as well as preservatives such as methyl para-hydroxybenzoate or propyl I 10 para-hydroxybenzoate.

I t It is preferred to apply the cosmetic composition by means of a light massage in order to cause it to penetrate properly, this application preferably being carried out in the evening so as to allow the composition to act and penetrate during the night.

The cosmetic compositions according to the invention have proved to be particularly favourable to improve the aesthetic appearance of the skin.

In order not to lose the benefit of the effects obtained, it is recommended in particular to continue treatment in the form of a sustained treatment for a period of 3 to 4 weeks at least once a year and preferably 2 to 3 times a year.

The multivitamin preparation which is administered orally consists essentially of a mixture of vitamins E, A, B2, H, B1 and C.

As can be seen, the oral preparation and the cosmetic composition are characterized essentially by the presence of some of the same vitamins, namely vitamin:, A, E, B2, B5 and

H.

Vitamin A is preferably administered orally in the 15 form of provitamin A ((-carotene).

Vitamin Bl or thiamine is preferably administered in its hydrochloride or nitrate form and vitamin C or Lascorbic acid in the form of its calcium or sodium salts or in the form of ascorbyl palmitate.

20 The daily doses of these vitamins which have to be administered, in one or more doses, are as follows: Provitamin A ((-carotene).... 1.2 to 30 mg Vitamin 3.75 to 30 mg Vitamin 0.3 to 5 mg Vitamin 2.5 to 15 mg Vitamin 0.075 to 0.45 mg Vitamin 0.3 to 2 mg Vitamin to 200 mg The orally administered preparation may also contain other vitamins, especially vitamin D, vitamin PP, vitamin B6 (pyridoxine hydrochloride), as well as certain mineral elements (Se and Cu) and oligo-elements such as for example magnesium glycerophosphate, magnesium citrate, magnesium gluconate, ferrous phosphate, cupric citrate, cupric gluconate, zinc acetate, zinc histidine, zinc gluconate, zinc chloride, selenite salts as well as selenium methionine.

These orally administered compositions may take different forms, especially the form of tablets, a powder, 4404 0 0 4 44 I 9 granules, pills, capsules, gelatin capsules or in the form of a syrup, a suspension or a solution.

Among these different forms those which are especially preferred are capsules and gelatin capsules.

According to a preferred embodiment, the vitamin mixture is combined with at least one edible vegetable oil such as, for example, safflower oil, wheatgerm oil, oil of oenothera seeds, borage oil, oil of blackcurrant seeds, peanut oil, soybean oil, or with an animal oil of marine 10 origin which is rich in polyunsaturated fatty acids.

These oils are particularly recommended inasmuch as .o they provide linoleic acid as well as o-linoleic acid (essential fatty acids).

The orally taken preparation may also contain various So 15 conventional ingredients such as, for example, fillers, sweeteners, etc...

The following orally taken preparations have proved to S° be particularly suitable: S~ca A 462 mg soft gelatin capsule S 20 Composition per capsule: Peanut 103 mg Hydrogenated soybean 15.0 mg Safflower 85 mg (-carotene in oily suspension...... 3.45 mg 25 (0.69 mg of P-carotene) Vitamin 7.5 mg Vitamin 0.780 mg Vitamin 0.863 mg Vitamin 5.0 mg Vitamin 0.150 mg Vitamin C (ascorbic 25.0 mg 70.0 mg In order to have the required doses of vitamins, two 462.mg capsules are adminstered per day.
