it refers to a new group of acetal monoesters and diesters which have in its structure the ester function and cyclic ethers that give these products excellent properties as solvency , plasticity in polymers , solubility in polar and nonpolar means , spreadability , wetting , low volatility , non - toxicity and biodegradability . these properties make these products excellent candidates as solvents in formulations of pesticides , agricultural herbicides , for the paint and leather industry in domestic or industrial hygiene formulations ; as plasticizers for polymers such as polyvinyl chloride , nitrocellulose , cellulose , acrylics , polyvinyl vinyl and its copolymers ; as lubricants in industrial formulations , textile industry ; as emollients agents which donate oiliness for the cosmetic industry ; as wetting agents that are commonly used , and as biodiesel additives to reduce the freezing point and to improve its combustion .
