Description

[0102] The invention will be further described with reference to the following non-limiting examples as follows:

[0103] Mono and Di rhamnolipids were extracted and purified from a commercial sample of JBR425, supplied by Jeneil, using Supercritical CO.sub.2 using the following method.

[0104] A commercial sample of JBR425 (ex Jeneil) was mixed with a Celite 454 support and transferred to a supercritical CO2 extractor. The temperature and pressure was increased to produce supercritical CO2 and residual oils and fats were removed from the extractor in a defatting step. A cosolvent, industrial methylated solvent (IMS) was then added to the remaining defatted rhamnolipid mixture on the Cellte 454 support in the presence of supercritical CO2. The co-solvent IMS was introduced at an increasing gradient from 2.5% to 10% to facilitate the separation and removal of the different mono and di rhamnolipid ratios.

[0105] Method for Making the Cleaning Composition

[0106] Laundry and hand dish washing formulations were produced by mixing ingredients via a Heidolf Mixer.

[0107] For Laundry Initially a large scale batch between 100 and 1 L was produced with composition as defined in the formulation sheets.

[0108] The formulations were made and the order of addition as indicated in the formulations below.

[0109] Method for Measuring Viscosity of the Samples

[0110] Formulations were produced according to the Protocol. The rheological properties were then assessed using an Anton Paar ASC Rheometer at 25 C.

[0111] The rheology measurement was performed with the serrated cup and bob geometry. The bob used was the CC27/P2 SN9625 with the serrated cup related to this geometry. Each cup contained between 24 g to 26 g of samples. All the cups were maintained at 25 C. by a Jumbalo F32 thermo bath.

[0112] The rheological measurement contains three different steps: [0113] Step 1 shear stress control measurements from 0.01 Pa to 400 Pa. [0114] Step 2 shear rate control measurements from 0.1 s.sup.1 to 1200 s.sup.1. [0115] Step 3 shear rate control measurements from 1200s.sup.1 to 0.1 s.sup.1.

[0116] After the experimental measurement was carried out we collected the data from the Rheoplus software for analysis. The data presented shows the viscosity of the formulation at a shear rate of 23 s.sup.1 as this corresponds to the pouring viscosity of the formulation

[0120] Rhamnolipid JBR 425 is a mixture of mono and Di rhamnolipids where the IUPAC name for mono rhamnolipid is 3-[3-[(2R,3R,4R,5R,6S)-3,4,5-trihydroxy-6-methyloxan-2-yl]oxydecanoyloxy]decanoic acid and Di rhamnolipid is 3-[3-[4,5-dihydroxy-6-methyl-3-(3,4,5-trihydroxy-6-methyloxan-2-yl)oxyoxan-2-yl]oxydecanoyloxy]decanoic acid

[0121] Mono and Di rhamnolipids were extracted and purified from a commercial sample of JBR425, supplied by Jeneil, using Supercritcal CO2 using the following method.

[0122] A commercial sample of JBR425 was mixed with a celllite 454 support and transferred to a Supercritical CO2 extractor. The Temperature and pressure was increased to produce Supercritical CO2 and residual oils and fats were removed from the extractor (defatting) A cosolvent (Industrial Methylated Solvent) was then added to the remaining defatted rhamnolipid on the cellite 454 support in the presence of Supercritical CO2. The IMS is introduced at an increasing gradient from 2.5% to 10% to facilitate the separation and removal of the different mono and di rhamnolipid components.

[0125] Conclusions

[0126] The results show that to produce a formulation at desirably higher pouring viscosity in the presence of EPEI and perfume using thickening polymers to achieve the pouring viscosity then the inclusion of a glycolipid such as rhamnolipids is required to produce a stable formulation.
