Natrasorb® Bath is a specialty starch designed for bath powders, offering unique functionality. Its processing allows it to absorb and carry large quantities of oils and anhydrous liquids, such as bath oils, in a solid powder form. The starch creates "pockets" that hold the oils, and once it comes in contact with water, it immediately dissolves, releasing the oils for a smooth bath experience.

The adsorption evaluations were done by weighing the starch into a Hobart mixer, atomizing the oil onto the starch, mixing until homogeneous, and subjectively assessing the f low properties. 

 

Safety & Health

Health and Safety

Natrasorb® Bath starch is an organic particulate. Although it is not prone to dusting, use of a dust mask and good ventilation are recommended. Avoid contact of the powder or dust with heat, sparks or open flame. It is non GM (not genetically modified).

Storage & Handling

Storage and Handling Information

Natrasorb® Bath starch should be stored in a cool, dry location away from heat, sparks or fire. Good industrial hygiene practices should be followed when working with this starch.
