Definitions
- the present invention relates to a process for preparing liquid detergent compositions comprising an anionic surfactant and a nonionic surfactant. More in particular, it relates to a process for the continuous preparation of a liquid detergent composition comprising an anionic and a nonionic surfactant, and having a high surfactant content.
- EP-A-265 203 discloses liquid surfactant compositions which are mobile at 20 to 80 °C and contain a sodium or potassium salt of an alkylbenzene sulphonate or alkyl sulphate in an amount not exceeding 80% by weight; an ethoxylated nonionic surfactant in an amount not exceeding 80% by weight; and water in an amount not exceeding 10% by weight.
- Such liquid surfactant composition may be used as a concentrated liquid detergent, for example as a dishwashing liquid.
- the liquid surfactant composition may be sprayed onto a solid particulate absorbent material, for instance a porous spray-dried base powder having a low bulk density and containing no or little actives, to form a detergent base powder having an increased bulk density.
- a solid particulate absorbent material for instance a porous spray-dried base powder having a low bulk density and containing no or little actives, to form a detergent base powder having an increased bulk density.
- EP-A-265 203 describes two methods for preparing such concentrated liquid surfactant compositions.
- liquid nonionic surfactant is gradually added to a neutralized alkylbenzene paste (neutralized salt) which will typically have an active matter content of about 50% by weight.
- neutralized alkylbenzene paste neutralized salt
- the resulting viscous mixture containing more than 10% water is then heated to evaporate a sufficient amount of water such that the final water content will fall below 10%.
- alkylbenzene sulphonic acid is mixed with nonionic surfactant, and the mixture is subsequently treated with a sufficient amount of concentrated aqueous sodium hydroxide or potassium hydroxide to effect partial or complete neutralization.
- JP-A-6447755 describes a method of preparing high concentration organic sulphuric acid ester salts or organic sulphonic acid salts, wherein liquid acid precursors of the anionic surfactants are neutralized in the presence of a liquid nonionic surfactant.
- the nonionic surfactant must be added to the liquid acid precursor prior to the neutralization step, optionally as a mix with the neutralizing base.
- It is therefore an object of the present invention to provide an improved process for preparing a liquid surfactant composition comprising an anionic surfactant and a nonionic surfactant and having a relatively low water content.
- the present invention provides a process for preparing a liquid surfactant composition
- a liquid surfactant composition comprising an anionic surfactant and a nonionic surfactant characterized by blending essentially equimolar amounts of a neutralizing agent and a liquid acid precursor of the anionic surfactant simultaneously with the nonionic surfactant, the liquid surfactant composition having a water content of less than 25% by weight, wherein the anionic surfactant is an alkylbenzene sulphonate.
- the process is carried out continuously, more preferably in a loop reactor.
- the principle of the process of the invention is to neutralize the acid corresponding to the anionic surfactant with a neutralizing agent of a strength such as to lead to the desired low level of water in the final product by adding these two materials to a fluid which comprises the nonionic surfactant and which acts as a solvent or diluent for the neutralized anionic surfactant.
- the liquid acid corresponding to the anionic surfactant or acid anionic surfactant precursor is usually a stable organic compound which is commercially available.
- An example is Dobanic 113, C 12 -C 15 alkylbenzene sulphonic acid, which can be obtained from Shell.
- the neutralizing agent can be in principle any suitable alkaline substance, preferably in a concentrated aqueous solution.
- Concentrated aqueous solutions of an alkali metal hydroxide, such as a 50% by weight solution of sodium hydroxide in water are the preferred neutralizing agents.
- concentrated alkaline silicate solutions could be used.
- the process of the invention for preparing the surfactant mixtures may be carried out batch-wise, for instance by adding equimolar amounts of the anionic precursor and the neutralizing agent to a reaction vessel containing the required amount of nonionic surfactant under continuous stirring and at a controlled temperature.
- the process is carried out continuously, by feeding the anionic surfactant precursor, the nonionic surfactant and the neutralizing agent continuously and in the required amounts into a reactor and collecting the formed liquid surfactant composition after neutralization has taken place.
- the process is carried out continuously in a loop reactor.
- loop reactors are known in the art and have, as far as we are aware, only been used for carrying out the neutralization of acid anionic surfactant precursors with aqueous sodium hydroxide.
- the liquid surfactant compositions prepared according to the present invention usually correspond to the liquid surfactant compositions described in the European patent application 265,203, but also liquid compositions having a higher water content may be prepared.
- the water content of the surfactant mixtures prepared according to the present invention is less than 25% by weight, preferably less than 15% by weight. A water content of less than 10% by weight is especially preferred.
- the prepared liquid surfactant compositions comprise 1 to 80%, preferably 15 to 80% by weight of one or more anionic surfactants, 10 to 99%, preferably 10 to 85% by weight of one or more nonionic surfactants and as little water as possible, in order to keep the composition mobile in the temperature range of 20-95 °C. Most preferred ranges for the surfactants are 30 to 70% by weight for the anionic and 30 to 70% by weight for the nonionic.
- the anionic surfactant component in the composition may be a sodium or potassium salt of a liquid acid surfactant precursor.
- Particularly suitable are sodium alkyl benzene sulphonates wherein the alkyl group possesses 10 to 18 carbon atoms. Mixtures of these anionic surfactants may also be used.
- the nonionic surfactant may be any suitable nonionic surfactant that is liquid or readily liquefiable at temperatures up to about 80°C.
- suitable types of nonionic surfactants for this purpose are the ethoxylated fatty alcohols, for example a C 12 -C 15 aliphatic alcohol ethoxylated with 2 to 10 moles of ethylene oxide per mole of alcohol.
- preferred nonionics are the C 13 -C 15 fatty alcohols condensated with 3 or 7 ethoxy groups, such as those commercially available from ICI as Synperonics A3 or A7 (Trade Marks).
- the weight ratio between the anionic surfactant and the nonionic surfactant in the obtained surfactant mixture is preferably in the range of 0.125:1 to 4:1.
- compositions having a high an anionic to nonionic ratio of more than about 1.5:1 were found to be in general more viscous and are therefore less preferred.
- the especially preferred compositions prepared according to the present process have an anionic to nonionic ratio of from 0.2:1 to 2:1.
- the liquid surfactant compositions prepared according to the process of the present invention may additionally contain free fatty acid.
- they may additionally comprise 0.5 to 20%, preferably 2 to 15%, more preferably 2 to 7% by weight of a fatty acid having 8 to 22 carbon atoms. It is preferred if the fatty acid possesses 12 to 20 carbon atoms, and more in particular 16 to 18 carbon atoms.
- liquid surfactant compositions prepared according to the process of the present invention may be favourably applied in a process for making high bulk density granular detergent compositions having a high active detergent level, as disclosed by EP-A- 367 339.
- the following mobile liquid Alkylbenzene sulphonate/Nonionic surfactant mixtures were prepared in a conventional neutralization loop reactor.
- the reactor is essentially in the form of a closed loop and comprises an in-line mixer. Down stream is a heat exchanging facility and before the mixer there are three inlets which are used for the liquid acid anionic precursor, the nonionic and the aqueous sodium hydroxide. Further up stream an outlet is provided through which the neutralized surfactant composition may be bled off, the majority of the product being recirculated into the loop.
- nonionic surfactant a blend of Synperonic A3 and Synperonic A7 in a ratio of 4 : 3.
- the nonionic surfactant mixture aqueous 48% by weight sodium hydroxide solution and liquid anionic acid precursor (Dobanic 113) were dosed in continuously, whereby the amount of sodium hydroxide was chosen to be just sufficient to neutralize the acid.
- the nonionic feed rate was set at three different levels. The feed rates of the starting materials and the calculated compositions of the obtained surfactant blend are given below.
- the coolant temperature was 50°C.
- Example 1 2 3 Anionic acid Feed Rate (kg/hr) 10 10 10 NaOH (48%) Feed Rate (kg/hr) 2.59 2.59 2.59 NI Feed Rate (kg/hr) 21 11.5 5.25 % Anionic detergent 30.7 44.0 54.7 % Nonionic detergent 63.6 48.3 35.7 % H 2 O 5.7 7.7 10 Ratio Anionic/Nonionic 0.5 1 2
- the surfactant compositions of Examples 1 and 2 were easily handleable in the loop and were mobile liquids at room temperature.
- the composition of Example 3 was more viscous and was therefore more difficult to handle.
