Definitions
- This invention is for improvements in or relating to hair-treating preparations and is especially, though not exclusively, concerned with. the preparation of materials used in the so-called cold permanent waving of hair, particularly human hair.
- a mercaptan is dissolved in water, the pH adjusted to a suitable value, and the resulting solution applied to the hair in order to soften or relax the hair and therefore to condition the hair for change in configuration.
- mercaptans which may be used in this process as well as the over-all process are described, for example, in British patent specification No. 589,956.
- the treated hair is manipulated to a desired configuration, which if desired is then set by treating the; hair with a solution of an oxidising agent such as potassium bromate.
- the advantages of the use of a powder compared with a solution are:
- the active material is in a concentrated form, which is desirable from the point of view of transport costs
- a powder may be dissolved in varying amounts of water to suit difierent types of hair;
- the material may be packed in envelopes of paper or other material instead of bottles, with considerable saving in packing cost.
- a process for preparing a solid composition containing a derivative of a mercapto carboxylic acid suitable on dissolution in water to form a hair-relaxing solution comprises neutralising a ice mercapto carboxylic acid with solid ammonium carbonate or bicarbonate, or a solid mixture of these, and in corporating either simultaneously or subsequently a proportion of a solid alkaliwhich is substantially more basic than the said ammonium salts.
- the proportion of stronger alkali will vary according to the precise conditions of the process and with the properties of the stronger alkali. As will be evident, the precise quantity to be employed in any particular case can readily be determined by simple preliminary trial, regard being had to the following criteria and to the examples hereinafter given.
- the stronger alkali has two functions: Firstly, it must be sufficiently strongly basic and be present in a sufiicient quantity to ensure that a pH of 9.0-9.5 is obtained when the powder prepared by the method described below is subsequently dissolved in water. Secondly, it must be in sufiicient quantity to absorb any water liberated in the formation of the ammonium salt, thus ensuring a relatively free-flowing powder.
- the solid (stronger) alkali is preferably a suitable sodium or potassium compound for example, the carbonates and tri-metal phosphates.
- a suitable sodium or potassium compound for example, the carbonates and tri-metal phosphates.
- such strongly basic substances as the metal hydroxides are avoided since, in significant quantity, they give when dissolved in water a pH higher than the permissible maximum.
- the ammonium salt and the stronger alkali simultaneously to the mercapto carboxylic acid.
- the two alkaline substances compete for reaction with the acid and the relative proportions of the two alkaline substances i such that the endothermic reaction of the ammonium salt and the exothermic reaction of the stronger alkali proceed simultaneously without an excessive rise in temperature such as to bring about any substantial thermal decomposition.
- Example I Gm. Thioglycollic acid 20 Commercial ammonium carbonate (powdered) 20 Sodium carbonate 24 The thioglycollic acid and ammonium carbonate are stirred together until no more carbon dioxide is liberated. The sodium carbonate is then added and the whole stirred until a dry, free-flowing powder is obtained.
- a suitable solution for use in cold permanent waving may be obtained by dissolving 15 gm. of the powder in ml. of Water.
- Example 11 Gm. Thioglycollic acid (95%) 20 Ammonium bicarbonate l6 Trisodium phosphate 45 The ammonium bicarbonate and trisodium phosphate powders are mixed together and added all at once to the thioglycollic acid, and the whole stirred till a dry, freeflowing powder is obtained.
- a solution suitable for cold permanent waving may be prepared by dissolving 20 gm. of the powder in 100 ml. of water.
- the powders of the present invention when dissolved in water may also be employed in conjunction with suitable water-soluble dyestuffs, preferably coal-tar dyestuffs, in the process of dyeing hair described in specification No. 267,193 with or without simultaneous waving of the hair.
- suitable water-soluble dyestuffs preferably coal-tar dyestuffs
- ammonium carbonate may also include commercial ammonium carbonate, which is us ually a mixture of ammonium bicarbonate and ammonium carbamate.
- a process for preparing a solid composition containing a derivative of a mercapto carboxylic acid suitable on dissolution in water to form a hair-relaxing solution which comprises neutralising a mercapto carboxylic acid with a member of the class consisting of solid ammonium carbonate, solid ammonium bicarbonate and a solid mixture of these two salts, and incorporating a solid alkali which is substantially more basic than the said ammonium salt in sufiicient quantity to absorb any water formed in the reaction and to bring the composition to an acidity such that an aqueous solution of it has a pH of 9.0 to 9.5.
- a process for preparing a solid composition containing a derivative of a mercapto carboxylic acid suitable on dissolution in water to form a hair-relaxing solution which comprises neutralising a mercapto carboxylic acid with a member of the class consisting of solid ammonium carbonate, solid ammonium bicarbonate and a solid mixture of these two salts, and simultaneously incorporating a solid alkali which is substantially more basic than the said ammonium salt. in sufficient quantity to absorb any water formed in the reaction and to bring the composition to an acidity such that an aqueous solution of it has a pH of 9.0 to 9.5.
- a process for preparing a solid composition containing a derivative of a mercapto carboxylic acid suitable on dissolution in water to form a hair-relaxing solution which comprises neutralising a mercapto carboxylic acid with a member of the class consisting of solid ammonium carbonate, solid ammonium bicarbonate and a solid mixture of these two salts, and subsequently incorporating a solid alkali which is substantially more basic than the said ammonium salt. in sufiicient quantity to absorb any water formed in the reaction and to bring the composition to an acidity such that an aqueous solution of it has a pH of 9.0 to 9.5.
- a process as claimed in claim 1 wherein the said more basic solid alkali is selected from the group consisting of sodium carbonate and tri-sodiurn phosphate.
