♦RSAW ESB70/ZA is a versatile cosmetic-grade raw material and widely used in the formulation of shampoos, foam bath preparations, other toiletry and cleaning products.

♦RSAW ESB70/ZA is especially useful in high active formulations by virtue of its excellent solubility characteristics and mildness to the skin.

♦Dilution

The method of dilution should always be to add the RSAW ESB70/ZA to the water and not the reverse; otherwise an extremely viscous product will result.

Our technical department is available to discuss and give the guidance on any particular aspect of the use of this product.

RSAW ESB70/ZA is sensitive to changes in temperature and pH. Decomposition can occur at temperatures above 40 °C or in acidic conditions ( pH below 5 ).

Decomposition is caused by hydrolysis and decomposed product, being acid, will catalyse further hydrolysis.

Store at a temperature below its set point will require re-heating with consequent danger of over-heating and decomposition especially close to the source of heating.

Such extreme conditions of storage, handling and use should be avoided.

RSAW ESB70/ZA contains a small amount of citric acid,acting as pH buffer and therefore counteract hydrolysis. Store at 15-40°C is recommended.
