Definitions

  • the present invention relates to an aqueous liquid detergent composition, in which the detergent-active material is or comprises a soap.
  • Soap-based liquid detergent compositions are well-known in the art. Because of the water- solubility limits of the commonly-known soaps, such soap-based liquids contain either a relatively low concentration of soap, when soap is the sole detergent-active material in these liquids, or they contain, next to the soap, e.g. another synthetic detergent-active material, by the presence whereof the concentration of soap in the liquid can be made higher.
  • detergent compositions which include a mixture of mono-ethanolamine and/or potassium soaps of C 7 ⁇ C 9 fatty acids and C 14 ⁇ C 22 , preferably unsaturated fatty acids.
  • Compositions in addition should contain a nonionic emulsifier and an organic solvent.
  • Soap-based liquid detergent compositions often suffer from physical drawbacks; thus, for example, it is a problem to prepare a liquid composition which is physically stable, has a satisfactory pourability or viscosity, or which does not gel. Overcoming these problems often creates another one, i.e. that in doing so the washing and laundering efficacy of the composition is impaired.
  • an object of the present invention to provide an aqueous, soap-based liquid detergent composition which is physically stable, has satisfactory pourability or viscosity characteristics, which does not gel and which has a satisfactory washing, laundering and cleaning performance.
  • the soap component a sodium soap of linoleic acid. It has been found that if the soap component contains a sodium linoleate (a further definition of the soap component will follow below), the liquid detergent composition has a satisfactory detergency over a broad temperature range and can contain a relatively high concentration of a soap. The detergency efficacy is less impaired by the water hardness than with soap systems not containing the linoleate.
  • the soap component may consist solely of sodium linoleate, which may in practice, however, meet with cost and availability problems. Therefore-and this is a preferred embodiment of the invention-it has been found that if the soap component, next to the sodium linoleate, also contains a sodium soap of a C 16- C 24 mono-unsaturated fatty acid, the same benefits are obtained to practically the same degree.
  • the soap component contains a mixture of sodium linoleate and sodium oleate, such that at least 10% by weight of the soap component consists of sodium linoleate, quite satisfactory liquid products are obtained; particularly as regards its detergency over a broad temperature range.
  • Such mixtures can e.g. be obtained from the soapstock fatty acids, obtained from refining and margarine industries.
  • a sodium soap of palmitoleic, petroselinic, vaccenic, gadoleic, eicosenoic, cetoleic, erucic and selacholeic acid can also be used.
  • the soap component may consist solely of the mixture of sodium linoleate and sodium oleate, but it has been found that certain amounts of certain saturated fatty acid sodium soaps can be tolerated without significantly impairing the benefits of the present invention. Thus it has been found that the soap component may contain not more than 20% by weight of a saturated C 16- C 24 fatty acid soap. However, this saturated fatty acid soap may not be a sodium laurate or sodium myristate, since the presence thereof significantly detracts from the benefits of the present invention. Small amounts, i.e.
  • sodium soaps of saturated C 16- C 24 fatty acids are sodium palmitate, sodium margarate, sodium stearate, sodium nonadecylate, sodium arachidate, sodium heneicosinate, sodium behenate, sodium tricosanate, sodium lignocerate, and sodium soaps of trans-fatty acids of hardened oils and fats.
  • soaps i.e. sodium linoleate plus sodium oleate plus not more than 20% by weight of a soap of a saturated C 16- C 24 fatty acid
  • suitable sources which contain these fatty acids in the appropriate proportions.
  • sources are grapeseed oil, chufa oil, groundnut oil, maize oil, mustard seed oil, soybean oil, sesame oil, sunflower oil, cottonseed oil, rapeseed oil and tall oil fatty acids. Of these, the last-mentioned five oils and the tall oil fatty acids are preferred.
  • the sodium soaps may be prepared by neutralizing the fatty acids, obtained from these sources and this is preferred when tall oil fatty acids are used.
  • the sodium soap can also be prepared in a practical and advantageous manner by carrying out saponification of the oil in the presence of suitable emulsifying agents and neutralization of the fatty acids in situ in the liquid detergent composition. In this manner, an easy way of preparing the compositions of the invention is provided, leading to physically stable products.
  • an emulsifying agent is present in the liquid in which the saponification takes place.
  • emulsifying agents are e.g. nonionic detergent surfactants like the ethoxylation and/or propoxylation products of linear or branched- chain primary or secondary, natural or synthetic alcohols having 8-24 carbon atoms in their alkyl chain, of mono- or dialkylphenols having from 8-18 carbon atoms in their alkyl chain, of C S- C 22 fatty acids, of polyethylene- or polypropylene-glycols, of C 8 ⁇ C 22 fatty amines, -amides or -alkylolamides and so on.
  • nonionic detergent surfactants like the ethoxylation and/or propoxylation products of linear or branched- chain primary or secondary, natural or synthetic alcohols having 8-24 carbon atoms in their alkyl chain, of mono- or dialkylphenols having from 8-18 carbon atoms in their alkyl chain, of C S- C 22 fatty acids
  • Tertiary amine oxides having one C 8 ⁇ C 18 alkyl chain and two C 1 -C S alkyl chains are also included in the term nonionic detergent.
  • Amphoteric and zwitterionic detergents may also be used, such as sulphobetaines, amido-betaines, alkyl- aminocarboxylic acids etc.
  • compositions of the invention contain from 0-40% by weight of a nonionic detergent material (0% only in the case where the sodium linoleate or sodium linoleate/sodium oleate constitutes the whole of the soap component, and is not prepared by in situ saponification and neutralization) and preferably from 5-30% of a nonionic detergent material is present.
  • the amount of the soap component in the liquid composition is from 2.5-40, preferably 5-35% by weight.
  • compositions of the invention may furthermore contain hydrotropes, buffers, fluorescers, soil-suspending agents, enzymes, stabilizers for enzymes, dyes, perfumes, antioxidants and so on, all in amounts usually encountered in products of this type.
  • Sequestrant builders can also be included in an amount of up to 20% by weight.
  • the tall oil fatty acids were replaced by fatty acids, derived from soybean, sunflower-, rapeseed- and cottonseen oil, and mixtures thereof. This was done in the following way: the mixture of the lye, the triethanolamine, the nonionic detergent and water was heated till 80°C, after which the oil was added. Subsequently, after cooling till 60°C, the isopropyl alcohol was added, and subsequently, after further cooling, the enzyme and the other ingredients.
  • sunflower oil fatty acids With sunflower oil fatty acids: the liquids were stable at a 10 and 1 5% soap level in the whole range of 10-25% nonionic detergent, and also at the 20% soap level with 15% nonionic detergent.
  • rapeseed oil fatty acids the liquids were all stable in the whole soap range of 10-25% and in the whole nonionic detergent range of 10-25%. With cottonseed oil fatty acids, stability was obtained at the 10% soap level in the nonionic range of 10-25%, as well as at the 15% soap level and 15% nonionic level. Mixtures of soybean- and rapeseed oil fatty acids (ratio of 1 to 1) gave products, which were stable at nearly all soap and nonionic levels within the 10-25% range.
  • Example 1 Using coconut dimethyl amine oxide (5%) in the formulation of Example 1 as the nonionic with 5, 10, 15 and 20% sodium soap of soybean oil fatty acids (saponified and neutralized in situ) gave stable products.
  • liquid compositions C and D were assessed for detergency in a Tergoto- meter at 60°C, 15 minutes washing, hardness 26° French hardness (only Ca2+) at a dosage of 8, 9.5 and 11 1 g/I.
  • Three types of soiled standard test pieces (WFK, ERTC and VCD) were used, and the number of repeats was 8.
  • compositions were as follows:
