• q, s, and t each independently, are an integer from 1 to 3
• X ⁇ is a softener compatible anion.
• the esterquat is produced by reacting about 1.65 (1.5 to 1.75) moles of fatty acid methyl ester with one mole of alkanol amine followed by quaternization with dimethyl sulfate (further details on this preparation method are disclosed in U.S. Pat. No. 3,915,867). Using this ratio controls the amount of each of monoesterquat, diesterquat, and triesterquat in the composition.
• the alkanol amine comprises triethanolamine.
• Monoesterquat is more soluble in water than triesterquat. Depending on the AI, more or less monoesterquat is desired. At higher AI levels (usually at least 7 %), more monoesterquat as compared to triesterquat is desired so that the esterquat is more soluble in the water so that the esterquat can be delivered to fabric during use. At lower AI levels (usually up to 3%), less monoesterquat is desired because during use, it is desired for the esterquat to leave solution and deposit on fabric to effect fabric softening. Depending on the AI, the amount of monoesterquat and triesterquat are adjusted to balance solubility and delivery of the esterquat.
• reaction products are 50-65 weight % diesterquat, 20-40 weight % monoester, and 25 weight % or less triester, which are shown below:
• the amount of diesterquat is 52-60, 53-58, or 53-55 weight %. In other embodiments, the amount of monoesterquat is 30-40 or 35-40 weight %. In other embodiments, the amount of triesterquat is 1-12 or 8-11 weight %.
• the percentages, by weight, of mono, di, and tri esterquats, as described above are determined by the quantitative analytical method described in the publication “Characterisation of quaternized triethanolamine esters (esterquats) by HPLC, HRCGC and NMR” A. J. Wilkes, C. Jacobs, G. Walraven and J. M. Talbot—Colgate Palmolive R&D Inc.—4 th world Surfactants Congress, Barcelone, 3-7 VI 1996, page 382.
• the percentages, by weight, of the mono, di and tri esterquats measured on dried samples are normalized on the basis of 100%.
• the normalization is required due to the presence of 10% to 15%, by weight, of non-quaternized species, such as ester amines and free fatty acids. Accordingly, the normalized weight percentages refer to the pure esterquat component of the raw material. In other words, for the weight % of each of monoesterquat, diesterquat, and triesterquat, the weight % is based on the total amount of monoesterquat, diesterquat, and triesterquat in the composition.
• the percentage of saturated fatty acids based on the total weight of fatty acids is 45 to 75%. Esterquat compositions using this percentage of saturated fatty acids do not suffer from the processing drawbacks of 100% saturated materials. When used in fabric softening, the compositions provide good consumer perceived fabric softness while retaining good fragrance delivery.
• the amount is at least 50, 55, 60, 65 or 70 up to 75%. In other embodiments, the amount is no more than 70, 65, 60, 55, or 50 down to 45%. In other embodiments, the amount is 50 to 70%, 55 to 65%, or 57.5 to 67.5%. In one embodiment, the percentage of the fatty acid chains that are saturated is about 62.5% by weight of the fatty acid. In this embodiment, this can be obtained from a 50:50 ratio of hard:soft fatty acid.
• a ratio of hard fatty acid to soft fatty acid is 70:30 to 40:60. In other embodiments, the ratio is 60:40 to 40:60 or 55:45 to 45:55.
• the ratio is about 50:50. Because in these specific embodiments, each of the hard fatty acid and soft fatty acid cover ranges for different levels of saturation (hydrogenation), the actual percentage of fatty acids that are fully saturated can vary. In certain embodiments, soft tallow contains approximately 47% saturated chains by weight.
• the percentage of saturated fatty acids can be achieved by using a mixture of fatty acids to make the esterquat, or the percentage can be achieved by blending esterquats with different amounts of saturated fatty acids.
• the fatty acids can be any fatty acid that is used for manufacturing esterquats for fabric softening.
