Definitions

  • THIS INVENTION relates to surface active compositions.
  • sulphating agents for example H 2 S0 4 , S0 3 or SO 2 Cl 2 and neutralising with an amine for example a C l to C 5 mono alkyl amine or ammonia or with an alkali or alkaline earth base or ammonium compound to give the salt which is normally produced as a concentrate containing for example 65 to 75% by weight of the salt and a minor amount of water which includes any water of neutralisation and any introduced as solvent for the neutralising agent.
  • Such concentrates are normally viscous liquids, but if free inorganic sulphates, for example sodium sulphate, or the unsulphated alcohol ethoxylate is present the concentrate may become an elastic gell which is difficult to handle.
  • the alcohol-ether sulphate salts are normally transported as concentrates and then diluted with water and optionally other materials to produce the product ultimately used by the consumer. On dilution of the concentrate another gell of a particularly troublesome type is encountered when a composition of about 55% of the alcohol ether sulphate salt and 45% of water is reached. Frequently ethanol is added to break the gells and allow dilution, but this represents a considerable expense and becuase of its volatility, a fire hazard.
  • a compound other than a sulphate or sulphate salt
  • average molecular weight 500 to 10,000 preferably 500 to 6,000 and more preferably 1,000 to 3,000
  • the compound comprising a total of at least two ether linkages per seven carbon atoms, for example a polyethylene glycol of average molecular weight 500 to 6,000 reduces the problem of dilution with water.
  • the said compounds are of low volatility, and the quantities required are small.
  • the invention comprises a composition comprising a salt of an alcohol ether sulphate of formula [RO(C 2 H 4 O) n SO 3 ] - m M m+ where R and n are as previously defined, M is an ammonium, substituted ammcnium, alkali or alkaline earth metal ion and m is the valency of M, and a gel inhibiting quantity of a compound (other than a sulphate or sulphate salt) of average molecular weight 500 to 10,000, preferably 500 to 6,000 and more preferably 1,000 to 3,000, which comprises at least one polyalkylene glycol chain, the compound comprising a total of at least two ether linkages per seven carbon atoms, for example a polyethylene glycol.
  • the compound may be a polyalkylene or mixed polyalkylene glycol, for example polyethylene glycol or a mixed polyethylene/polypropylene glycol, a compound comprising a polyalkylene glycol chain linked to a phenol or alcohol for example an alkyl phenol (suitably having 4 to 12 carbon atoms in its alkyl group or groups) or alcohol (suitably having 1 to 16 and preferably 10 to 16 carbon atoms)/ethylene oxide condensate or with two or more polyalkylene glycol chains linked to a residue of a compound having two or more active hydrogen atoms, for example, glycerol or butane 1,4 diol.
  • the compound is very suitably a polyethylene glycol.
  • a gel inhibiting quantity is meant an amount sufficient to reduce the maximum elasticity of any gel encountered during dilution with water to at most 4 x 10 -4 Newtons per sq mm and preferably at most 1 x 10 -4 Newtons. In general 0.5 to 5% by weight of polyethylene glycol is used.
  • Compositions according to the invention tend to be thixotropic; they are readily pumpable in suitable conventional equipment.
  • the salt is suitably a sodium, potassium, magnesium or ammonium salt, and may be produced by neutralising the acid with a hydroxide, carbonate or bicarbonate of the cation. Direct neutralisation with ammonia or an amine may be carried out.
  • the invention also comprises a process in which the alcohol ether sulphate salt is mixed with a gel inhibiting amount of a compound (other than a sulphate or sulphate salt) of average molecular weight 500 to 10,000, preferably 500 to 6,000 and more preferably 1,000 to 3,000, which comprises at least one polyalkylene glycol chain, the compound comprising a total of at least two ether linkages per seven carbon atoms, for example a polyethylene glycol,and then diluted with water.
  • a compound other than a sulphate or sulphate salt of average molecular weight 500 to 10,000, preferably 500 to 6,000 and more preferably 1,000 to 3,000, which comprises at least one polyalkylene glycol chain, the compound comprising a total of at least two ether linkages per seven carbon atoms, for example a polyethylene glycol,and then diluted with water.
  • the compound has at least two ether linkages per five carbon atoms.
  • a sodium salt of a mixed C 13 and C 15 alcohol (7 to 3 by molar ratio) ethoxylated with an average of 3 mole C 2 H 4 O per mole of alcohol, sulphated with S0 3 and neutralised with NaOH solution to produce a 70% mixture by weight of the salt with water (hereinafter referred to as material A) was tested in an oscillating can rheometer to determine its dynamic viscosity and elasticity at a frequency of oscillation of 9.8 cycles per second. Material A with the specified additives was also tested in the same way.
  • Material A with 2.5% w/w of polyethylene glycol (800 mol wt) added had a dynamic viscosity under the same conditions of 37 poise at low shear and an elasticity of 3.2 x 10 -4 N mm -2 .
  • Material A with 1% w/w polyethylene glycol (1,COO mol wt) added had a dynamic viscosity under the same conditions of 34 poise at low shear and an elasticity of 4.1 x 10 -4 N mm -2 .
  • Material A with 21 ⁇ 2 w/w polyethylene glycol (1,000 mol wt) added had a dynamic viscosity under the same conditions of 36 poise at low shear and an elasticity of 2.1 x 10 -4 N mm -2 .
  • Synperonic TLE is a commercial product produced by alkoxylating methanol. It contains 28 ether links per 63 carbon atoms and has a molecular weight of 1,400.
  • “Synperonic”A50 is a commercial product produced by condensing a mixed C l3 and C 15 alcohol (7 to 3 by molar ratio) with c. 50 moles of ethylene oxide per mole.
  • Synperonic OP40 is a product of condensing octyl phenol with c. 40 moles of ethylene oxide per mole.
  • M.W. means molecular weight
