ABSTRACT:
The present invention is drawn to a process for providing emolliency to the skin using a series so called “spider esters”. These esters are derived from poly-hydroxy functional compounds sequentially reacted with ethylene oxide or propylene oxide, followed by the reaction of the alkoxylate with fatty acid. The resulting products are called spider esters because they resemble the spider, wherein appendages are alkoxylated esters. The restrictions this orientation imposes on rotation allows for the preparation of polar esters that have little or no water solubility, and provide both moisturization to the skin and emolliency by reducing transepidermal water loss.
