Definitions

• the surfactant material in such compositions usually comprises one or more surfactants which may be soap or non-soap synthetic surfactants.
• Soap is a particularly useful material since it is capable of a multiplicity of roles. It can be used as a detergent-active agent, as a builder and as a fabric softening agent. Thus, it is a very desirable aim to formulate liquid detergents which are relatively rich in soap. In the case of isotropic liquids containing little or no inorganic builder, it is relatively easy to formulate with high soap levels. It is much more difficult to incorporate large enough quantities in the aqueous structured liquids referred to above.
• the term electrolyte means any water-­soluble salt.
• the amount of electrolyte should be sufficient to cause formation of a lamellar phase by the soap/surfactant to endow solid suspending capability.
• the composition comprises at least 1.0% by weight, more preferably at least 5.0% by weight, most preferably at least 17.0% by weight of electrolyte.
• the electrolyte may also be a detergency builder, such as the inorganic builder sodium tripolyphosphate, or it may be a non-functional electrolyte, such as sodium sulphate or chloride.
• the inorganic builder comprises all or part of the electrolyte.
• compositions must also be capable of suspending particulate solids although particularly preferred are those systems where such solids are actually in suspension.
• the solids may be undissolved electrolyte, the same or different from the electrolyte in solution, the latter being saturated in electrolyte. Additionally or alternatively, they may be materials which are substantially insoluble in water alone. Examples of such substantially insoluble materials are aluminosilicate builders and particles of calcite abrasive.
• Suitable nonionic surfactants which may be used include in particular the reaction products of compounds having a hydrophobic group and a reactive hydrogen atom, for example aliphatic alcohols, acids, amides or alkyl phenols with alkylene oxides, especially ethylene oxide either alone or with propylene oxide.
• Specific nonionic detergent compounds are alkyl (C6-C22) phenols-ethylene oxide condensates, the condensation products of aliphatic (C8-C18) primary or secondary linear or branched alcohols with ethylene oxide, and products made by condensation of ethylene oxide with the reaction products of propylene oxide and ethylene diamine.
• Other so-called nonionic detergent compounds include long-­chain tertiary amine oxides, long-chain tertiary phosphine oxides and dialkyl sulphoxides.
• compositions of the present invention preferably also contain a builder in addition to the soap.
• the non-­ soap builder is preferably present at a level of at least 5% by weight; the maximum level is preferably 30%.
• a detergency builder is any material which is capable of reducing the level of free calcium ions in the wash liquor and will preferably provide the composition with other beneficial properties such as the generation of an alkaline pH, and the suspension of soil removed from the fabric. They may be classed as inorganic, organic non-­polymeric and organic polymeric. Generally, we prefer that any inorganic builder comprises all or part of the electrolyte (provided water-soluble).
• phosphorus-containing inorganic detergency builders include the water-soluble salts, especially alkaline metal pyrophosphates, orthophosphates, polyphosphates and phosphonates.
• specific examples of inorganic phosphate builders include sodium and potassium tripolyphosphates, phosphates and hexametaphosphates.
