Sokalan® HP 30 Booster is also highly compatible with concentrated products, offering broad application in the liquid detergent category.
Liquid laundry detergent demand soared during the pandemic, as a focus on hygiene, more time spent in the home, and a desire to stock up on the essentials sent consumers heading for the checkout lane (or, more accurately, the ecommerce cart)
The post-pandemic landscape indicates a continued desire for efficacious, powerful cleaning products – liquid laundry among them – but also a return to the pre-pandemic rise in desire for sustainable home care solutions.
This dual demand for efficacy and sustainability is putting increased pressure on formulators to deliver new products that fit the bill. There are a small handful of levers that can be pulled to alter performance in liquid laundry products. One of the most compelling is the use of polymers.
How do polymers impact liquid laundry detergent?
Polymers are an incredibly broad category of materials comprised of repeating molecule chains. Potential applications for polymers span nearly every conceivable industry, but there are benefits to leveraging them in liquid laundry detergent formulations.
In liquid laundry, some of these benefits include:
- Enhanced soil release
- Prevention of redeposits of dirt during the wash cycle
- Inhibition of dye transfer
- Reduced temperature sensitivity, and strong performance at lower temperatures
- Compatibility with concentrated formulas
To appeal to both consumer trends – cleaning performance and more sustainable solutions -concentrated formulas and high performance at low temperatures are more important than ever. The liquid detergent market has transitioned to concentrated formats over time, with a particular rise in unit dose formulations (Source: Euromonitor 2021). Low temperature performance is a strong market need and enables the sustainability benefit that comes with reduced energy usage.
Introducing Sokalan® HP 30 Booster
Sokalan HP 30 Booster from BASF fills a noted gap in the market. Sokalan HP 30 Booster is specifically formulated to address oily stain removal, even at low temperatures. Oily stains are notoriously challenging in liquid laundry, and superior efficacy at low temperatures is something consumers and brands alike have been asking for.
In addition to low temperature oily stain removal, Sokalan HP 30 Booster has a high-active content (100%) formulation that makes this polymer optimal for concentrated formulas.
Blend for broad spectrum stain removal
Sokalan HP 30 Booster has been shown to be highly effective at concentrations as low as 1% against tough stains like bacon grease, butter and oil. The chart below shows results of NA3 baseline (a model premium liquid detergent) plus 1% and 2% Sokalan HP 30 Booster. Note the prevalence of green results (indicating statistical improvements) in the oily category.
Sokalan HP 30 Booster also combines well with other polymers, including the Sokalan HP 20 product from BASF, which is highly effective against stains from oxidizable/bleachable stains and clay. Formulations with 1% of HP 30 Booster and 1% HP 20 offers broad spectrum stain removal at low temperatures.
What you need to know
Sokalan HP 30 Booster is an alkoxylated polyethleneimine with a pH level of approximately 10, viscosity of 1500 mPas (at 23 degrees Centigrade) and density of 1.06 g/cm3 (at 20 degrees Centigrade). It is available as a flowable liquid with 100% actives content.
Ready for action
Combining low temperature performance, compatibility with concentrated performance and superior oily stain removal, Sokalan HP 30 Booster offers a high-value method of enhancing a liquid laundry detergent formulation to meet current customer demands.
With expectations of efficacy and sustainability expected to rise – along with an unwillingness to compromise one for the other – polymers like Sokalan HP 30 Booster are going to be in increasing demand.
