Definitions

• This invention relates to detergents for textiles, notably those consisting of synthetic linear polymers, and in particular to such detergents which also exercise an antistatic effect.
• the ingredient of the present detergents responsible (or mainly responsible) for their detergency is an anionic surface active agent, i.e. a water-soluble compound, having lipophilic and hydrophilic groups in the anion (of. pages 108 and 109 of Surface Active Agents," by C. B. F. Young and K. W. Carns, 1945, Chemical Publishing Co. Inc.), a genus which includes, inter alia, the alkali soaps, e.g. sodium stearate (a constituent of common soap), alkali metal fatty alcohol sulphates, e.g. sodium cetyl sulphate, alkylarly sulphonates, e.g. sodium p-dodecylbenzene sulphonate and alkyl monoglyceryl phosphates or sulphates, e.g. dodecyl octyl monoglyceryl phosphate.
• an anionic surface active agent i.e. a water-soluble compound,
• the present detergents also contain a convertional water-soluble inorganic salt of neutral or alkaline reaction, e.g. sodium carbonate, sodium sulphate, sodium borate.
• a convertional water-soluble inorganic salt of neutral or alkaline reaction e.g. sodium carbonate, sodium sulphate, sodium borate.
• the cationic agent is first mixed with sufficient of an inorganic salt powder, before the incorporation of the anionic agent, the aforesaid precipitation can be avoided. It is preferred that the cationic agent be applied in the form of a solution, to a sufficiency of the solid inorganic salt, so as to coat the individual crystals or granules thereof without making the powder, as a whole, wet. Mixtures so obtained can be safely mixed with the desired anionic surface active agent without fear of precipitation occurring when the resulting detergent mixture is dissolved in water for use in washing.
• the anti-static effect produced ICC by the employment of the present detergents withstands rinsing and tends even to increase during the course of successive washings.
• the present detergents also appear to have the advantage of hindering re-deposition of the dirt on the fabric whilst it is in the wash liquor.
• the present invention relates to a process for making detergents comprising mixing an alcoholic, aqueous or aqueous-alcoholic solution of a cationic surface active agent, 7111011 15 a quaternary ammonium, phosphromum or l'l'lOlPhOlll'llllIl'l salt, with a sufficient quantity of a powdered water-sofible alkaline-reagting or neutral-reacting inorganic salt, so that the weight of fiid salt remaimng undrssolved 1s not less than themeight of tlia cationic surface active agent, d yfiggll fii fiifl to remove any visible liquid, and then intimatelv mixing face active agefirearpid eaf Whendrying'is'elfectedin order to remove any visible liquid, the dried product is advantageously powdered so as to facilitate the subsequent mixing with the anionic surface active agent.
• the qnantity of the solution of the cationic surface active agent employed should only suffice to coat the individual crystals or granules of the inorganic salt powder, without making the latter visibly wet. In this case there is thus no visible liquid present and therefore no drying is required.
• the anionic surface active agent may be introduced either as the pure compound or, for example, in the form of an aqueous solution or paste, or otherwise conveniently diluted.
• an anti-static effect is produced even when the proportion of cationic surface active agent to anionic surface active agent is as low as 1-500 or even 1-1000. However, it is preferred that the weight of the anionic agent be from 10 to 200 times the weight of the cationic agent.
• the cationic surface active agent may be for example:
• Octadecyl-trimethylammonium chloride Octadecenyl-trimethylammonium chloride Octadecadienyl-trimethylammonium chloride
• Dodecyl-trimethylammonium chloride Hexadecyl-trimethylammonium chloride Didodecyl-dimethylammonium bromide Dioctadecyl-dimethylarnmonium chloride
• Benzyl tri-(dimethylamino) phosphonium chloride Benzyl-stearyl-dimethylammonium chloride Hexadecyl methyl morpholinium methosulphate Hexadecyl pyridinium chloride
• Dodecyl pyridinium chloride Those cationic surface active agents are preferred which are capable of imparting a strong antistatic effect when applied to the textile material by themselves.
• anionic surface active agent may be, for example:
• Example 1 9.85 parts of a 75% solution of dioctadecyl-dimethylammonium chloride in iso-propanol are diluted with 6 of methanol and thoroughly mixed with 12 parts of anhydrous sodium carbonate powder. The resulting powder is then mixed with 50 parts of common soap powder.
• a plain weave fabric of 30 denier nylon yarn (10 filaments) is washed repeatedly and examined as to its tendency to become electrostatically charged in the following manner:
• the fabric divided into 11 strips, is immersed and agitated for 3 minutes, in 100 times its own weight of a 0.1% aqueous solution of the above detergent at 60 C.
• the fabric strips are then removed, rinsed once with warm water and twice with cold water, and dried.
• One strip is set aside and the remaining ten washed again, rinsed and dried as before.
• Another strip is set aside and the process repeated until the final strip has received 11 washes.
• Example 2 detergent and tested in the way described in Example 1. The following results being obtained:
• Example 3 20 parts of sodium p-dodecyl benzene sulphonate 40 parts of sodium tripolyphosphate 40 parts of sodium sulphate The resultant mixture constitutes the detergent; the ratio by weight of anionic to cationic agent contained therein is 2:1.
• Strips of nylon fabric are washed with times their weight of a 0.1% aqueous solution of the above detergent at 60 C. and the electrostatic charge produced measured as described in Example 1. It is found that the charge is only about 15 of that generated on the unwashed fabric.
• Example 4 Example 3 is repeated except that only 2 parts of the 50% solution of cationic agent are taken. The electrostatic charge is 30% of that found on the unwashed fabric.
• a process for the manufacture of a detergent composition comprising mixing an alcoholic solution of a cationic surface active agent, selected from the group consisting of quaternary ammonium, phosphonium and morpholinium salt, with a sufiicient quantity of a powdered sodium salt selected from the group consisting of anhydrous sodium carbonate, sodium carbonate decahydrate, sodium bicarbonate, sodium borate, sodium sulphate, trisodium orthophosphate, sodium metaphosphate, sodium pyrophosphate, disodium hydrogen phosphate, sodium tripolyphosphate and sodium perborate, so that the weight of said salt remaining undissolved is not less than the weight of the cationic surface active agent, drying if necessary to remove any visible liquid, and then intimately mixing with a quantity of a synthetic organic anionic surface active agent weighing from 2 to 1000 times the weight of the cationic surface active agent employed.
• a cationic surface active agent selected from the group consisting of quaternary ammonium, phosphonium and morpholinium salt
• the process of claim surface active agent is from of the cationic agent.
