Abstract
C.588 (R) ABSTRACT
A liquid, soap-based detergent composition having a satis-factory detergency over a broad temperature range, being less sensitive to water hardness, is obtained by using a linoleate soap which is substantially free from lauric soaps. Mixtures of oleate/linolate soaps, optionally with small amounts of stearic soaps, can equally be used. These soap blends are better soluble than coconut/oleate soap blends.

Description
1 3~65~7 - 1 - C 588 (R) ~QUEOUS, 50AP-BASED LIQUID DETERGENT COMPOSITION
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 wel1-known in the art.
Because of the water-solubility limits of the commonly-known soaps, such soap-based liquids contain either a relatively low concentra-tion of soap, when soap is the sole detergent-active material in these liquids, or they contain, next to the soap, another synthetic ; 10 deteryent-active material, by the presence whereof the concen-tration of soap in the liquid can be made higher.
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 launder-ing efficac~v of the composition is impaired.
Hence it is 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 c~anin~ performance.

- 2 - C 588 (R) linoleate (a further definition of the soap component will follow below), the liquid detergent composition has a satisfactory deter-gency over a broad temperature range and can contain a relatively high concentration of soap. The detergency efficacy is less impaired by the water hardness than with soap systems not containiny the linoleate.
; As stated above, it is an essential feature that in the soap com-~; ponent a sodium linoleate is used. The soap component may consistsolely 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 C16-C24 mono-unsaturated fatty acid, the same benefits are obtained to practically the same degree. Thus, it has been found that if the soap component contains a mixture of sodium linoleate and sodium oleate, in such a relative weight proportion that at least 10% by weight of the sum of these two soaps consists of sodium linoleate, quite satisfactory liquid products are obtained, particularly as regards its deteraency over a broad temperature range. Such mixtures can e.g. be obtained from the soapstock fatty acids, obtained from refining and margarine industries. Instead ;, of, or in addition to sodium oleate, 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 up to 20% by weight of a saturated C16-C2~ fatty acid - ~ soap. However, this saturated fatty acid soap may not be a sodium laurate or sodium myristate, since the presence thereof signifi-cantly detracts from the benefits of the present invention. Small amounts, i.e. up to 5, preferably 3%, can be tolerable, provided there is sufFicient linoleate or lino7eate plus oleate present, but it is highly preferred that no sodium laurate or :: :

- 3 - C 588 (R) sodium myristate is present in the soap comconent. Typical examples of sodium soaps of saturated C16 and high fatty acids are sodium palmitate, sodium margarate, sodiurn 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.
Mixtures of the above-identified soaps, i.e. sodium linoleate plus sodlum oleate plus up to 20~ of a soap of a saturated C16-C24 fatty acid can be obtained from the separate fatty acids, bu~ may also be obtained from suitable sources which contain these fatty acids in the appropriate proportions. Such 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 fattyacids. 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.
In the case of the other suitable oils, however3 it has been found that 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.
~`
It is essential in this process that an emulsifying agent is present in the liquid in which the saponification takes place. Such emulsi-fying agents are e.g. nonionic detergent surfactants like theethoxylation 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 thier alkyl chain, of C8-C22 fatty acids, of polyethylene- or polypropylene-~lycols, of C8-C22 fatty amines, -amides or -alkylolamides and so on. Tertiary amine oxides havin~ one C8-C18 alkyl chain and two C1-C5 alkyl chains are also included in the term nonionic detergent. Amphoteric and zwitterionic detergents may also be used, such as sulphobetaines, amido-betaines, * ~

~ C 583 (R) alkylaminocarboxylic acids etc.
The amount of such emulsifying agen-t is not critical; in fact it is often desirable to add more than is necessary ~or the saponifi-cation, i.e. in the cases where the presence of a nonionic detergentin the compositions of the invention is required ~or further improved washing and laundering efficacy, e.g. in underbuilt ~ituatlons as well as physical stability. In general therefore the compositions of the invention contain from 0-40% by weight of a nonionic detergent material (0% only ;n the case where the sodium linoleate or sodium linoleate/
sodium oleate constitutes the whole nf 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 generally from 2.5-40, preferably 5-35% by weight.
The compositions of the invention may furthermore contain hydro-tropes, buffers, fluorescers, soil-suspending agents, enzymes, stabilizers for enzymes, dyes, perfumes, anti-oxidants 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 2-0% by weight.

These liquid compositions were stable: they remained homogeneous after the two weeks' storage at 0C.
_ample 2 In the formulations of Example 1, the tall oil fatty acids were replaced by fatty acids, derived from soybean-, sunflower-, rape-seed- and cottonseed oil, and mixtures thereof. This was done in the following way: the mixture of the 1ye, the triethanolamine, the nonionic detergent and water was heated till sac, after which ~he oil was added. Subsequently, after cooling ti11 60C 7 the ; isopropyl alcohol was addedg and subsequently,after further cool-ing~the enzyme and the other ingredients.
Similar formulations were prepared in the same manner,with varying amounts of soap and nonionic detergent. These formulations were stored for 2 weeks at 0C, and their phase stability was assessed.
The following results were obtained:

` With soybean oil fatty acids: the liquids were stable at the 10~
soap level in the whole range of 10-25% of the nonionic detergent.
With sunflower oil fatty acids: the liquids were stable at a 10 and 15Yo soap level in the whole range of 10-25% nonionic detergent, and also at the 20% soap level with 15% nonionic detergent.

as well as at the 15~ soap level and 15% nonionic level. Mix-tures of soybean- and rapeseedoil fatty acids (ratio of 1 to 1) gave products, which were stable at nearly all soap and non-ionic levels within the 10- 25% range.
