The present invention relates to oligoesters and their use or the creation of additives. Oligoester containing additives and/or oligoesters themselves may be used for formulating pharmaceutical preparations, cosmetics or personal care products such as shampoos and conditioners. These oligoesters are particularly useful for the creation of multi-purpose additives that can impart conditioning, long substantivity and/or UV protection. Individual oligoesters and oligoester mixtures are described.
Quaternaryammoniumsalts were synthesized from ammoniumsalts and dialkyl carbonates over imidazolium ionic liquid catalysts. The reaction gave almost stoichiometric amounts of the quaternaryammoniumsalts for halides and nitrates. It was found that the electron-donating property of the alkyl moieties of ammonium cations, the electrophilic nature of the alkyl group of the carbonate, the acidity of
Mixture of dialkyl imidazoline quats with specified substitution content are provided. In one embodiment, at least a portion of the mixture includes at least one dialkyl imidazoline quat having at least one C

Methods of making imidazoline quats and quat mixtures, personal care and cosmetic products and formulations that contain the imidazoline quats and quat mixtures, methods of making such personal care and cosmetic products and formulations, and methods of using the such imidazoline quats, quat mixtures, and personal care and cosmetic products and formulations are also provided. Various embodiments are disclosed.
