Abstract: Esters of acetals of chemical structure: are provided which have excellent solubility power in sunscreens, excellent properties of emollience, spreadability and ease of preparing stable aqueous formulas, are completely non-toxic, have no characteristics that generate ocular or cutaneous irritation, and these properties enable their use as solubilizers and emollients in cosmetic formulations for body use, facial sunscreens, makeup removers and component for use in roll-on deodorants.

Abstract: A process of crude glycerin purification originated from transesterification with alkaline catalysis without using acidification and distillation producing purified glycerin 96% and 99% purity, wherein the purification technique of glycerin obtained from productions of fatty esters using the alkaline catalysis.

Abstract: 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.
