United States Patent 3,109,777 COMPOSITIONS FOR TREATMENT OF THE HAIR Charles Zviak, La Garenne, France, assignor to LOreal, Paris, France, a corporation of France No Drawing. Filed June 24, 1959, Ser. No. 822,410 Claims priority, application France June 26, 1958 10 Claims. (Cl. 167-87) This invention relates to compositions suitable for application to the human hair for cleansing and other purposes.

It is known that the presence of thiodigly-colic acid, which often exists as an impurity in thioglycolic acid solutions employed for permanently deforming the hair, is considered as harmful from the dermatological viewpoint. In this connection, the article by E. H. Graul in Dermatolog. Wochenschrift 121, 579 8 7 (1950) may be consulted; see also American Chemical Abstracts (1953), 9573 1.

It has now surprisingly been found that the presence of thiodiglycolic acid or of an ester or of an amide derived from this acid in a hair tonic composition or lotion for the care of the hair reduces irritation of the scalp even in particularly sensitive persons and is more particularly advantageous for persons suffering from seborrhea.

According to the present invention therefore, there are provided hair tonic compositions or lotions suitable for application to human hair which comprise an aqueous or alcoholic solution containing from 0.2% to 10% and preferably from 0.5% to of a compound of the general formula:

CH2-C OX wherein X designates OH, NH or a --OR group, where R represents an alkyl or hydroxyalkyl group comprising at most three carbon atoms, and one :or more adjuvants known per se for inclusion in compositions for application to the hair.

The hair tonic compositions according to the invention may thus constitute a simple lotion for the care of the hair e.g. one containing as the adjuvant an essential oil, perfume or the like or it may constitute a shampoo containing detergent materials of known types.

Where the composition is in the form of a shampoo containing a cationic detergent and having an acid pH, it is preferable to use thiodiglycolic acid or its amide rather than an ester.

The compositions just defined eliminate or substantially reduce scalp irritation in persons having a sensitive scalp and more particularly in those suffering from seborrhea. Moreover, the substances of the aforesaid general formula are manufactured on a large scale in the chemical industry for other purposes and are consequently obtainable at relative low cost.

Among the products which may be included in the hair tonic compositions according to the invention are:

(a) Cation-active materials, more especially quaternary ammonium derivatives,

([2) Amino compounds, such as glutamic acid and cystine,

(0) Products derived from vitamins, such as calcium pantothenate, ethyl nicotinate and pantothenic alcohol,

(d) Certain essential oils such as cedar oil, cade oil and lavender oil.

The compositions of the present invention may also contain superfatting products for imparting suppleness and lustre to the hair, such for example as glycol oleate and glycerol stearate.

2 The following examples, in which the percentages are given by weight, will serve to illustrate the invention:

Example 1 Hair tonic lotion containing:

0.5 0% of thiodigl-ycolic acid 0.05% of calcium pantothenate 0.01% of salicylic acid 0.50% of trimethylcetyl-amm-onium chloride Alcohol (25), q.s. for 100 Example 11 Hair tonic lotion containing:

1% of diglycolic ester of thiodiglycolic acid 2% of cade oil 5% of cedar oil 92% of lavender alcoholate Example III An aqueous alcoholic hair tonic lotion containing, in

45 alcohol:

0.50% of thiodiglycolic acid diamide 1.00% of alcohol-soluble ethoxylated derivatives of lanolin alcohols 0.25% of salicylic acid Example IV Example V A shampoo composed of:

4% of ethyl ester of thiodiglycolic acid 10% of sodium lauroylsarcosinate 2% of glycerol monostearate 1% of magnesium stearate Water, q.s. for

What I claim is:
