application Morocco January 3, 1949 2 Claims. (Cl. 167-88) The present invention relates to the dyeing of hair, and
more particularly to a stabl e cream-like hair dye.
In attempting to dye directly-hair by means of a dissolved true hair dyeing age nt, it has been found that a major amount of said dyeing agent remained in the solution, even in cases where momentary shading,
v subsequent shampooing or merely generate adye' sequent to a supplementary oxidizing treatment have been substituted for prove the stability of the hair dyeing.
termed indirect used in the form of creams to however,
which may be Creams of this type, when containing only conve in order that stable dyeing been proposed previously to dye solutions, could be facilitate their handling. have met with ditficulty, ntional reducing agents, and, creams be obtained, it has disperse thio-reducing agents in such indirect dyeing creams.
In contradistinction to sai improved characteristics.
A further object of the invention is to d indirect dyeing creams, the
provide direct hair dyeing creams containing only harmless dyeing agents.
Yet another object of this invention is to provide improved hair dyeing creams easily than vegetable dyes s Which uch as may be applied more natural henna, which are used in the form of water-containing pastes.
A further object of the invention is to provide an improved hair dyeing cream having improved efiiciency.
hair dyeing cream in invention comprises in combination: a c
a type, such as used for skin dyeing agent directly acting accordance with the present beauty treatment, a harmless on the hair keratin, which agent does not require any further chemical modification to generate the dyeing agent,

the transfer of said harmless Thus, an improved hair dyeing cream according to this invention includes a harml homogeneously swelling agent intended to ess dyeing agent distributed in a carrying cream, together with a improve the permeability of with respect to In such a hair dyeing crea the hair material.
m, the harmless dyeing agent may be dissolved in the carrying cream, or finely suspended in said cream, or els e partially dissolved and par tially suspended in the cream.
It is to be observed that with the area 1 are true dyeing agents, in c uble pigments such as used A hair dyeing cream acc Whether dissolved or the dyeing products blended finely suspended, ontradistinction to the insolfor make-up creams.
ording to the present invenand a wetting agent facilition enables the dyeing agent to be transferred easily to the hair by virtue of the three following efiects:
The dyeing agent is dissolved partially or totally in the ccireairn which is brought into contact with the hair to be The dyeing agent is dispersed in the form of fine particles which are suspended in the cream, and this agent is brought into direct contact with the hair to be treated; The swelling agent present in the cream containing the dyeing agent improves the permeability of the hair to said dyeing agent.
affinity may amount up to 10/ 1.
dyeing cream according to the invention is applied easily and does not aifect the scalp; such a dyeing cream actually dyes the hair instead of merely shading it; moreto the scalp is manifested.
According to the specific dyeing agent used the pH value of the cream may be either acid, or neutral, or alka- An acidity of the medium, if necessary, may be obtained by means of an organic or mineral acid.
A dyeing cream according to the invention further may include supplementary conventional treating and keeping up hair products, such as cholesterol, lecithin, etc.
Some specific formulations of dyeing creams in accordance with the present invention will now be described, but it is to be clearly understood that the specific exam ples disclosed are given as being illustrative only and are intended in no manner to limit the scope of the invention. In the following examples, all parts are by weight.
Example I Alkaline dyeing cream for dyeing agents acting in an alkaline medium:
Carrying cream: emulsifiable glycol stearate 10 Wetting agent: sulfonated lauryl alcohol 1 Dyeing agent: rhodamine 4 Treatment products:
Cholesterol l Lecithin .l Ammonia 22 Baum (20% solution) 5 erfume .5 Water 79.3 Example II Acidic cream for dyes acting in an acidic medium: Carrying cream:
Glycerine monostearate 10 Sapamine base 2 Wetting agent: Nekal BX (dibutyl naphthalene sodium sulfonate) l Dyeing agent: Lawsone (naphthoquinone) 2 Treatment products:
Cholesterol .1 Lecithin .1 Acetic acid I 1 Perfume .5 Water 83.3
Example III Neutral cream for dyes acting in a neutral medium:
Emulsifiable glycol stearate Glycol Wetting agent: sulfonated lauryl acid Dyeing agent: nitrated picramic acid Treatment products: Cholesterol Lecithin Ammonium acetate Perfume Water 83.9
Creams having the above formulations have an agreeable commercial appearance. They may be applied easily by reason of their consistency without requiring any dilution or heating. When the hair has been dyed conveniently, the cream carrying the dyeing agent is washed away by a mere rinsing or shampooing. In view of the fact that such creams do not comprise any mineral charge, the hair keeps its brilliancy and flexibility.
The dyeing creams according to this invention enable strong hair shades to be obtained resistant to any shampooing, whatever strong it may be. They may be used alone or incorporated with para or henna dyes to which very pleasant hues are given. No inconveniences result from the mixing of decoloring creams with para dyes, if in such a case alkaline creams are used.
Further, the dyeing creams according to the present invention may be applied before, during or after any conventional hair dye.
The dyeing agents are generally those which are present in henna leaves, Persian seed, walnut leaves and the like, or in the derivatives thereof.
On the other hand, owing to the nature of the carrying agent and to the fineness of dispersion, dyeing agents may be used which in conventional solution conditions did present only a little affinity, if any, with the hair keratin; such dyeing agents are found particularly in the following groups: naphthoquinone, phthaleine. acridin and thiazinic dyes, triphenylmethan, azoic and nitrated pyrazolone dyes, quinolein, resindulin, indigoid, indulin, thiobenzenylic dyes, oxazines, azosafranin, and stilbenic, thiazolic, azothiazolic, oxyquinonic, anthraquinonic, oxyanthraquinonic dyes. The above-mentioned specific dyeing agents have been given merely as illustrations, however, and obviously other dyeing agents could be used in practicing the invention.
Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is:
1. A creamy hair dyeing medium comprising in a homogeneous intimate blend; a carrying cream made of a substance selected from the group consisting of glycolmonoester, polyglycol-monoester, glycerol monoester of a fatty acid having high molecular weight; sulfonated lauryl alcohol as swelling agent for the hair, and a dermatologically harmless, synthetic, direct acting, nonoxidation dyestufi. having hair substantivity at room temperature, said dyestufi being relatively insoluble in water, the pH of said blend being at the value required by said synthetic dyestuff for dyeing hair.
2. A medium according to claim 1, wherein said dyestuif consists of nitrated picramic acid, with the addition of afmmonium acetate for required pH value of said dye- Sttl References Cited in the file of this patent UNITED STATES PATENTS cal Publ. 00., Brooklyn, N. Y., 1947.
