A major trend in the home care category is sustainability. This translates into the need for biodegradable and bio-sourced raw materials that perform well in target formulations. AECI Specialty Chemicals offers a range of biodegradable ingredients that fit these market needs.

SupraCare 780 is a cellulose derivative additive that combines rheology and structural benefits. This raw material acts as a highly efficient thickener in liquid detergents and as a structural agent in detergent bars, improving their physical and wear characteristics.

The additive is biodegradable (as per OECD 302B) and has a non-ionic structure, making it compatible in a wide range of formulations such as liquid laundry detergents, hand dishwashing liquids, hard surface cleaners, laundry bars, multi-purpose bars and non-soap bars.

This technology provides water structuring to solid formats (soap bars, laundry washing pearls and bars), allowing for dosage reduction of palm derivatives by up to 20%. The result is a more cost-effective formulation in an extremely cost-conscious category. It also helps to improve the sustainability of formulations.

Avoid soft, brittle bar soaps

SupraCare 780 additive helps to bind more water while maintaining the bar characteristics. Lower total fatty matter (TFM) results in reduced formulation costs. Solid formats have a brick-and-mortar structure. The brick is the hard phase and the mortar the liquid phase responsible for lather and mush.

The brick phase consists of the sodium stearate/PEG and the mortar phase consists of sodium laurate, sodium oleate, sodium palmitate, water, glycerine, electrolyte, mineral (part) and perfume. The bar will have a percolated brick structure with a continuous mortar phase (see figure 1). When more water is added the brick shrinks, i.e. the mortar is diluted, and the percolated structure compromised which softens the bar.

When sodium silicate is added, the brick grows, mortar is diluted and the percolative structure returns. Yet, there is a lack of cohesive force which leads to brittle and crumbling bars. SupraCare 780 can structure the mortar phase leading to regained bar cohesion and high-water structuring which is otherwise impossible to attain. By adding in just 0.5% of SupraCare 780 in a bar soap formulation, the TFM can be reduced by 16%.

Foam as a key performance attribute

Other benefits of SupraCare 780 include an up to 30% reduction in rate of wear and a 10% increase in foam generated. Besides cleansing capabilities, in the South African market foam is one of the most important attributes of a detergent bar. The end consumer connects the foam produced as an indication of cleansing.

SupraCare 780 can also be added to hand dishwashing liquids. As little as 0.3% is enough to thicken the hand dishwashing liquid (based on 10% of surfactants) while achieving a transparent formulation. The improved rheology gives the product a premium feel

with enhanced foaming. When compared to a state-of-the-art cellulosic rheology modifier, the SupraCare 780 additive outperformed in terms viscosity and enhanced foam. AECI Specialty Chemicals’ additive has proved to be an amazing technology for creating luxurious home care products, which are not only cost-effective but also sustainable.
