Definitions
- the present invention relates to aqueous light duty cleaning compositions and will be described herein with particular reference to hand dishwashing liquids.
- compositions typically comprise, as the principal surfactant component, one or more surfactants selected from a relatively small group.
- principal surfactants are typically selected from amongst primary alcohol sulphates (also known as primary alkyl sulphates) , secondary alkane sulphonates, linear alkyl benzene sulphonate, alkoxylated alcohols and alkyl ether sulphates.
- polyol derived surfactants such as alkylpolyglucosides, glucosamides and other sugar based surfactants, as well as alkyl glyceryl derivatives.
- hand dishwashing compositions are not structureds by the presence of a lamellar phase.
- compositions In addition to these principal surfactants it is commonplace for compositions to comprise a so-called 'foam-booster', selected from a ine oxides, alkanolamides (particularly the mono and di ethanolamides and isopropanolamides) and other nitrogen-based surfactant compounds, including poly-hydroxy amides and betaines .
- a so-called 'foam-booster' selected from a ine oxides, alkanolamides (particularly the mono and di ethanolamides and isopropanolamides) and other nitrogen-based surfactant compounds, including poly-hydroxy amides and betaines .
- R is typically C8-C18 alkyl and n is typically 1-14, or the related alkyl ether sulphates of the general formula:
- R is again alkyl and n is typically 1-5.
- a large proportion (often some 80%wt) of the total surfactant system comprises ether sulphates, with the balance of the actives comprising one or more foam-boosters.
- the overall active concentration on product typically varies from around 20% for 'economy' brands to around 40% for 'concentrated' products. Lower concentrations, down to 2% surfactant are known as are higher concentrations, up to 70% surfactant.
- the product comprising very high levels of surfactant are still aqueous, but may be in the form of pastes, gels or bars.
- a common problem in hand dishwashing is encountered when the soil removed from the articles being washed contains a significant level of fat, grease or other oily matter.
- typical in use levels of surfactant of 0.04%wt are sufficient to remove grease from the articles and suspend it as droplets, however, coalescence of these droplets may occur to produce large and visible bodies of fatty material. These bodies of material are unsightly and can be redeposited on the articles being washed, the hands of the user or the bowl surface. The presence of visible droplets of fatty material may cause the user to believe that the wash liquor is spent and lead the user to discard the wash liquor causing unnecessary further use of products and release of surfactant into the environment.
- EP 0221774 discloses the use of hydrophobic/hydrophilic linear block copolymers . Similar compositions are disclosed in EP 222557 (P&G, 1987) .

- Example II of this document discloses a composition which comprises 30% quaternary- fabric softener, 1-1.5% nonionic and 0.1-0.2% of a polymer.
- Example X of this document discloses compositions with various quats, 0.5% polymer and 1.5-2.0%.
- coalescence of oil droplets during the dishwashing process can be significantly retarded, without detriment to the spontaneous grease removal properties of the formulation, by the presence of selected polymers having a hydrophilic backbone and hydrophobic side chains.

- the oil-soluble hydrophobic side chains of the polymer partition into oil droplets, while the hydrophilic backbone remains in the waterphase to stabilise the droplets against coalescence through a combination of steric hindrance and electrostatic repulsion.
- the particular combinations of surfactants described above comprise non-charged surfactants and potentially surfactant complex-forming systems in which the charge of the anionic surfactant is in part shielded by the amphoteric or zwitterionic surfactant, this prevents significant complex formation between the anionic surfactant and the polymer which would otherwise inhibit the action of the polymer.

- Each petri dish had a cross marked on it centrally using permanent ink.
- Petri dishes were placed in a clean oven at 45 ⁇ 2°C for 5 minutes, removed from the oven and filled with 5mls of the fat (still maintained at 60 ⁇ 2°C ) ensuring uniform coverage. The dishes were left to cool at room temperature over a period of l%-2 hours before use.
- test solution of products A-E as described below was prepared at the desired concentration (typically 0.04%AD, e.g. lgm/l t of a 40% AD concentrate) using water of a specific hardness (typically 5, 12 or 24 deg FH) and heated to 50°C in a water bath.
- the hot test solution was poured into a large beaker (e.g. 2L) containing a layer of glass beads as insulation and minimising the volume of foam produced and placed back in the waterbath, the temperature being maintained at 50C.
- the test petri dish was added; time keeping was started as soon as the dish was submerged in the test solution. At the point at which the solution broke through to the glass surface on the base of the petri dish the time was recorded. The time at which the fat in each quadrant was fully removed was also recorded. While a tiny amount of small fatty speckles may have been left on the dish: where these covered a negligible fraction of the base, they were be ignored.
- Emulsions of olive oil in water were prepared with a phase ratio of 20:80 of the oil phase to the water phase, using a jet homogeniser (ex. LabPlant) at lOOpsi (7kg/cm 2 ) to obtain an emulsion with reproducible droplet sizes in the 1-10 micron range .

- Typical droplet sizes for products A and B are given below in table lc. Concentrations in table lc are given on product not on surfactant. D[4,3] and D[3,2] are in microns.
- the extent of coalescence which occurs in the presence of the formulations used was determined after centrifugation of 10ml samples in graduated centrifuge tubes for 800 mins at 2000rpm, under conditions so as to produce an acceleration of 895g.
- the volume of coalesced oil was measured to obtain an indication of the degree of coalescence expressed as a number in ml.
- the zeta potential is the potential at the plane of shear or slip, i.e. the plane which separates water of hydration from free water. Zeta potential was measured using a Malvern Zetasizer (TM) following the instructions supplied with it.
- TM Malvern Zetasizer
- Figure 1 shows a plot of the relationship between the percentage of coalescence (C%) which occurs under the conditions specified above and the time (T) taken to remove the grease from the Petri-dish using the method specified above. Experiments were performed in 12 FH water.

- the products used are specified by the letter used to identify them in tables la and lb.
- Figure 3 shows the effect of increasing water hardness on composition E in the presence of CP5 and DC1 polymers. Experiments were performed in both 12 and 24 FH water, using product E at a surfactant concentration of 0.6g/l. The polymer concentration in g/1 is plotted against the volume of oil coalesced from the emulsion after spinning at 2000 rpm for 800 minutes .
- Figures 4a and 4b show the effect of changing the polymer type on the rate of coalescence in the centrifuge as compared with the control in which the waterphase of the emulsion was derived from E as described above.
- the concentration of surfactant was 0.6g/l and where polymer was present it was present at a level of 0.075g/l.
- the control was an emulsion in which the waterphase was derived directly from E and did not contain any polymer.
- Table 2 shows the volume of oil coalesced after 800min as described above in the presence of simple surfactant systems.
- the systems have a total surfactant concentration of 0.6gm/litre and are 50/50 mixtures of the two surfactants found by reading down or across the table.
- Good performance is generally associated with an oil volume coalesced of 0.2ml, or less.
- Figures shown in bold and underlined in table 2 indicate formulations in which there is an improvement in the stability of the oil droplets in the presence of the polymer.
- the presence of nonionics and amphoterics is beneficial, but that poor results are generally obtained with PAS a strongly charged anionic surfactant.
- LES a less strongly charged anionic surfactant, shows some improvement over PAS .
- APG and APB containing systems can be improved to give very low levels of coalescence, and in general it can be seen that the addition of the DCl polymer never causes a significant increase in the coalescence, while more often than not, improves the coalescence score.
- Figure 5 shows the effect of changing the properties of the nonionic on the rate of coalescence both in the presence of polymer DCl and otherwise. Coalescence was measured as described above, i.e. by the centrifuge method using 24 FH water (i.e. moderately hard) to prepare the waterphase of the emulsion.
- the surfactants used are a series of ethoxylated nonionics with increasing degrees of ethoxylation. This increase in ethoxylation has the effect of increasing the hydrophile/lipophile balance of the surfactant.
