Abstract:
A process of making a host composition having a host capable of accepting a guest, the process comprising mixing, in any order:(i) a non-ionic surfactant selected from the group consisting of compounds having a chemical structure: where â€œâ€”CHâ€”Oâ€”CHâ€”â€  represents an epoxide-group, where Ra and Rb are hydrocarbons that can be the same or different, where at least one of the Ra and Rb hydrocarbons includes an epoxide group within 3 carbons of the hydrocarbon attachment to contribute to the desired hydro-lypid balance of 7-9, where Rc is hydrogen or a methyl group, and where Rd is a methylene group (â€”CH2â€”), an ethyl group(â€”CH2â€”CH2â€”), or a structurally-equivalent link with a bond length range about the same as or shorter than that provided by an ethyl group, and having a hydro-lipid balance in the range of 7-9, or any combination of two or more thereof; (ii) in a stoichiometric proportion of at least 1:6 relative to the non-ionic surfactant, an amphoteric surfactant selected from the group consisting of organic compounds-having the chemical formula NH3â€”Râ€”COOH, where R is a straight, branched, or aromatic hydrocarbon structure having 6-24 carbons, or any combination of two or more thereof; (iii) at least a sufficient amount of a solvent to dissolve the amphoteric surfactant, the sol vent comprising one or more compounds selected from the group consisting of water, alcohols having straight or branched hydrocarbon structure having up to 6 carbons, glycosamionoglucans, or any combination of two or more of the foregoing; (iv) in a stoichiometric proportion of at least 1:240 relative to the non-ionic surfactant, an aromatic selected from the group consisting of compounds having at least one aromatic five- or six-member ring, or any combination of two or more thereof; (v) in a stoichiometric proportion of at least 1:240 relative to the non-ionic surfactant, of an aluminum cation; (vi) in a stoichiometric proportion of at least 1:1200 relative to the non-ionic surfactant of at least one Lewis acid that is not a Bronsted-Lowry acid; (vii) at least 0.003 molar concentration of at least one Bronsted-Lowry acid.
