ChemSperse™ is a 100% bio-derived castor based polyester that is gently polymerized using ricinoleic acid. The resulting polyricinoleic acid (PRA) is oxidatively stable and non-volatile with an amorphous structure. ChemSperse™ is readily biodegradable with an ISO 16128 Natural Index of 1.
ChemSperse™ excels as a particle dispersant, showcasing effective wetting and dispersant stability. The polar structure interacts well with particles by effectively coating them, specifically favorable to iron oxides. Additionally, the high molecular weight and branched structure creates steric hinderance between particles which creates more stability in the dispersion, preventing agglomeration.
Due to the amorphous structure, ChemSperse™ will not crystallize, even in repeated freeze/thaw cycles. The low temperature fluidity and consistency make this material very easy to work with and store. No special heating or mixing required.
ChemSperse™ shows superior performance as a dispersant, wetting agent, SPF stabilizer, and hair conditioner.

Lists combine the ease of Bookmarks with the versatility of Tags. Instead of one collection of bookmarked items, create as many collections, called "Lists," as you need.
Find the link to your List page in the user menu.
All Tags have been converted to separate Lists, and your bookmarked items have been saved to a "Bookmarks" List.
When you click the Add to List button, a dropdown of your existing Lists appears. Click the List name to which you want to add this product or formula.
You can also create a new List. Simply click "Create a New List" and enter a name.
When you define a new List, the current item is automatically added to it. You can add a product or formula to as many Lists as you need.
Easily see which Lists this item appears in, and quickly go to that List from the links that appear on the page.
