Definitions

• This invention relates to materials and methods for cleansing the hair and particularly to compositions containing ditertiary diamines and their use.
• Anionic surface-active products such as alkyl-aryl-sulphonates and alkyl-sulphates, as usually employed for cleansing the hair have the advantage of being good detergents and having good foaming power.
• they have the disadvantage that they remove from the hair natural fatty substances to which it owes its flexibility and its lustre, and they thus render it dry and brittle.
• They are generally employed in an alkaline medium and cannot be used in a neutral or acid medium.
• These products do not act as softeners, this term being used in the sense in which it is usually employed in textile fibre treatment, that is to say, they do not facilitate the sliding of the hairs one upon the other and do not facilitate the application of dyes.
• non-ionic surface-active products can be employed for cleansing the hair. Such products are also good detergents and have good foaming power. They are free from some of the disadvantages of anionic products, but they also have no softening effect on the surface of the hair.
• Some cationic surface-active products such as quaternary ammonium salts and long-chain aliphatic amine salts, have also been proposed as products for cleansing the hair. They are generally rather poor detergents and they have the disadvantage of being noxious to the scalp. On the other hand, they have good softening properties, which also promote dyeing.
• compositions for use in cleansing the hair which comprise aqueous dispersions or solutions of at least one ditertiary aliphatic diamine of the general Formula I:
• R1 R! (I) wherein R represents a saturated or unsaturated straight or branched aliphatic group containing from 12 to 22 carbon atoms, two of the groups R R and R represent groups of the formula -(CH ),,OH and the other represents a group of the formula where x is 2 or 3 and n is nought or 1, or salt of such diamine, the composition having a pH of 3.5 to 6.
• a process of cleansing hair comprises applying thereto an aqueous composition as defined above.
• compounds of Formula I are preferably used inthe form of aqueous solutions or aqueous sols of their salts, as will hereinafter be explained in greater 2,930,761 Patented Mar. 29, 1960 tached to the nitrogen atom.
• They can be prepared from fatty amines or mixtures of fatty amines by the following process:
• Excellent products are obtained which have very high foaming power and are completely harmless to the skin by fixing, for example, an average of 3.5 molecules of ethylene oxide or propylene oxide on 1 molecule of alkylaminopropylamine.
• alkylaminopropylamines thus hydroxyethylated or hydroxypropylated are not soluble in water, but they can be dispersed in water. On the other hand, the majority of their salts are soluble in water.
• Salts. of the compounds-of Formula I can be formed with various mineral or organic acids. Mineral acids such as' hydrochloric acid or phosphoric acid may be employed. However, it is preferred to employ salts formed from fatty acids of low molecular weight-such as formic CHa-CHzOH ample. Any acid giving water-soluble salts with the compounds of Formula I may be employed. However, it will be advantageous to employ acids which are most compatible with the skin, notably hydroxyacids, such as lactic acid, whichin addition gives an unctuous foam.
• one or more compounds of Formula I heated at 7080' C. are neutralised by adding with good agitation, an aqueous solution heated at the same temperature of the acid employed.
• the pH of the solution obtained' may range from 3.5 to 6, depending upon the acid employed. Solutions of salts having a more acid pH lose some of their foaming power, and those with more alkaline pH lead to hydrolysis of the salts and deposition of cationic base.
• an aqueous solution containing 50% by weight of the dilactate of a compound of Formula I in which R has a chain length of 18 carbon atoms (oleyl or stearyl) is fluid at 60 C.
• aqueous solution containing by weight of the said dilactate remains fluid and limpid at room temperature and can be marketed in liquid form.
• Shampoos prepared with solutions of salts of compounds of Formula I give an abundantand consistent lather.
• the detergent action is such that all dirt on the hair is eliminated at the first wash and rinsing is simple.
• the salts of compounds of Formula I are insensitive to acid pH and to the alkaline-earth metal salts contained in the washing water. No deposition emanating from the product itself or from an action of the product on salts contained in the water takes place on the hair.
• the solution is allowed. to cool and a consistent and translucent gel is obtained, which can be directly employed as a concentrated shampoo.
• a composition for cleansing live human hair comprising an aqueous solution of the dilactate of N-lrydroxyethyl N di(hydroxyethyl) oleylamino propylamine of pH 3.5 to 6. 7
• composition for cleansing live human hair comprising an aqueous solution of the dilactate of N-hydroxyethwl-N' di(hydroxy ethoxyethyl) alkyl propylamine wherein the alkyl group is derived from thefatty acids of tallow, said solution having a pH of 3.5 to 6.
