“…Esterquats synthesized by esterification of triethanolamine with two equivalents of fatty acid give a thermodynamicallycontrolled statistical distribution of mono-, di-, and triesters, which commercially are quaternized with dimethyl sulphate [3]. It has been reported that esterquats establish a cleavable functionality within the "twin tails", which enhance their biodegradability by separating the positively charged nitrogen hydrophile from the hydrophobic part.…”

Rheological Behavior and Structure of a Commercial Esterquat Surfactant Aqueous System

Aqueous dispersions of a commercial esterquat-type surfactant widely used in fabric softeners were rheologically characterized. While at 4 wt % esterquat concentration, a Newtonian response was observed; non-Newtonian (Sisko) flow behavior and viscoelastic properties were found at 12 wt % and higher concentrations. The onset of nonlinear viscoelasticity in oscillatory shear provided interesting information on the strength of quiescent surfactant aggregates. Mechanical spectra corresponded to the plateau zone and the onset of the transition zone. The plateau modulus and the characteristic slopes of the relaxation spectra depended on the strength of the interactions among the aggregates. Start-up at the inception of the shear experiments were carried out to obtain information on the time-dependent shear behavior. Cryo-SEM micrographs demonstrated the occurrence of a dispersion of vesicles embedded into a bilayer matrix.

“…Typical fabric softener formulations consist of about 15% of a cationic surfactant, such as triethanolamine (TEA)-esterquats of fatty acids [40,41], in water. For the measurements, conjugates 13-16 were dissolved in ethyl acetate at a concentration to potentially release a total of 8.7 mg (0.05 mmol) of δ-damascone.…”

Abstract:Poly(styrene-co-maleic anhydride)s were modified with poly(propylene oxide (PO)-co-ethylene oxide (EO)) side chains (Jeffamine ® ) with different EO/PO molar ratios, varying between 0.11 and 3.60. These copolymers were then further functionalized with a β-mercapto ketone of δ-damascone. The obtained poly(maleic acid monoamide)-based β-mercapto ketones were then studied as delivery systems for the controlled release of δ-damascone by retro 1,4-addition. The release of δ-damascone, a volatile, bioactive molecule of the family of rose ketones, was studied by dynamic headspace analysis above a cotton surface after deposition of a cationic surfactant containing fabric softening formulation, as a function of the ethylene oxide (EO)/propylene oxide (PO) molar ratio of the grafted copolymer side chains. The polarity of the EO/PO side chain influenced the release efficiency of the damascone in a typical fabric softening application. PO-rich copolymers and the corresponding poly(styrene-co-maleic anhydride) without Jeffamine ® side chains were found to be less efficient for the desired fragrance release than the corresponding bioconjugate with a EO/PO ratio of 3.60 in the side chain. This copolymer conjugate seemed to represent a suitable balance between hydrophilicity and hydrophobicity to favor the release of the δ-damascone and to improve the deposition of the conjugate from an aqueous environment onto a cotton surface.
