Embodiment 1A

[0067] Example 1A: Preparation of Esterquats Using Natural Oils

[0068] Esteramine intermediate

[0069] The desired amount of sunflower oil was charged to a 3-liter 4-neck glass reactor equipped with mechanical stirring, reflux condenser, thermocouple and nitrogen blanket. MDEA was added to the reactor in an amount to obtain a molar ratio of 2 fatty acid groups to 1 amine, and potassium carbonate was added to the reaction mixture. The reaction mixture was stirred at 300 rpm and heated to 160°C under nitrogen until the free amine content stabilized between 2 and 3%. The resulting esteramine mixture was then cooled to room temperature. It will be appreciated that the resulting esteramine mixture comprises about 70% by weight esteramine and about 30% by weight glycerides, primarily monoglycerides and diglycerides, which are by-products of the reaction of MDEA and sunflower oil.

Embodiment approach 1

[0073] Embodiment 1: The esterquat mixture was diluted 15% with naturally derived propylene glycol. The diluted product was a low viscosity, light colored liquid comprising 85% by weight of the esterquat mixture and 15% by weight of propylene glycol.

Embodiment approach 2

[0074] Embodiment 2: The esterquat mixture was diluted 20% with a solvent mixture of 15% by weight lauryl lactyl lactylate and 5% by weight glycerin. The diluted product is a low viscosity liquid comprising 80% by weight of the esterquat mixture and 20% by weight of lauryl lactylate / glycerin solvent.

Abstract

Esterquat compositions are disclosed that comprise, based on the weight of the composition, 0% to about 70% by weight of a solvent, and about 30% to 100% by weight of a mixture comprising about 50% to about 80% by weight, based on the weight of the mixture, of esterquats and about 20% to about 50% by weight, based on the weight of the mixture, of mono- and diglycerides. The esterquat compositions can be prepared by the direct esterification of a natural oil with an alkanolamine, followed by quaternization in the presence of the solvent. The esterquat compositions can be formulated into hair care compositions that provide improved wet and dry combing properties.

Description

technical field [0001] The present technology relates to esterquat compositions useful in compositions such as hair care compositions. In particular, the present technology relates to esterquat compositions comprising a synergistic mixture of at least one esterquat with mono- and diglycerides that provides a higher level of Diglycerides for better wet and dry combing. The present technology also relates to hair care compositions comprising the esterquat compositions, and methods of making the esterquat compositions. Background technique [0002] Quaternary ammonium compounds have been used as hair conditioners for many years. The two most common hair conditioners are behenyltrimethylammonium chloride (BTAC) and cetyltrimethylammonium chloride (CETAC). Although both actives work well as conditioners, they have certain disadvantages. BTAC and CETAC have unfavorable environmental profiles and their use in conditioning compositions has come under scrutiny. Since 2014, the E...
