They are demanding laundry products that can help to reduce consumption of plastic packaging and that will have a longer-term approach to the world’s water scarcity issues. However, the trends in consumption tell a different story. As the use of powdered laundry detergent continues its steady decline, consumers are increasingly turning to the more convenient, but less sustainable, liquid laundry capsules, rather than the liquid laundry option which is remaining flat. At IMCD we have looked at how the formulation of new liquid laundry concentrates can help to meet the consumer demand for ‘greener’ solutions, reduce the amount of packaging and water required and remove the need for more the complicated manufacturing and formulation processes required by PVOH film pods. This article will demonstrate how a 25ml liquid laundry concentrate can maintain comparable cleaning performance and physical stability to liquid capsules from a leading European brand, while using more sustainable raw materials, and providing cost effective choices. The success of this solution will, however, lie with manufacturers to develop a suitably flexible and convenient package to ensure ease and accuracy of use for end-users.

In this study, dissolvable shower gel tablets for multiple uses have been developed in order to reduce the use of fresh plastic packaging. - Methods : The appropriate ratio of two surfactants, cocoyl glutamic acid (CGA) and sodium coco sulphate (SCS), was optimized using design of experiments. Additionally, skin hydration of the emollient either omega oil or glycerine was taken into account when determining its concentration. After that, powdered shower gel formulations were made and tested for their properties, including cleaning power, and foamability. On 30 human volunteers, the effects of reconstituted shower gel on skin redness, cleaning effectiveness and overall satisfaction were evaluated. - Results : The study found that, when cleaning power and foam height were taken into account, the proper surfactant ratio was 7.5:0 (SCS:CGA). The 5% glycerine shower gel formula demonstrated significantly greater skin hydration than other formulas. The in vivo study's findings demonstrated that there was no statistically significant difference between selected formulas (5% glycerine and 2.5% omega oil) in terms of cleaning ability. Comparing both formulas to the control, neither showed any skin redness. Additionally, it was discovered that the developed products were much more effective at cleaning and easier to use when washing for the volunteers than regular liquid soap. Overall satisfaction and the moisturizing feel were not significantly different among all products. - Conclusion : The formula with 7.5% SCS and 5% glycerine is said to be the best one for both cleaning ability and moisturizing effect. These findings suggest that dissolvable shower gel tablets with enhanced skin benefits could offer a promising innovation in the personal care industry.
