Natural hydrocarbon/ester compositions with improved sensory properties
Described herein is an invention that includes a spreadable conditioning composition comprising a blend of: a branched hydrocarbon and an ester having a kinematic viscosity of less than or equal to about 100 centistokes. The composition may be natural, for example, if each of the branched hydrocarbon and the ester are independently vegetable-derived. In addition, the composition may lack ingredients that are derived from a palm oil. In an embodiment, the composition is a blend of hydrogenated farnesene and an ester selected from glyceryl triheptanoate, heptyl undecylenate, and mixtures thereof. The composition exhibits an average spreading velocity of about 4 to about 8. Also disclosed are formulations for use in products of personal care, home/institutional care, industry, pharmaceutical and medical and veterinary care and related methods.
1 . A homogeneous spreadable conditioning composition for use in a personal care formulation, the homogeneous spreadable conditioning composition consisting of:
(i) a branched hydrocarbon in a concentration of about 30% to about 80% by weight, the branched hydrocarbon having at least three methyl branches and a total of X carbon atoms where X is an integer of 13 to 19 carbon atoms; and
(ii) an ester in a concentration of about 20% to about 70% by weight selected from the group consisting of: glyceryl triheptanoate, heptyl undecylenate, and mixtures thereof;
wherein the homogeneous spreadable conditioning composition has a kinematic viscosity of less than or equal to about 25 centistokes at 25° C.; and
wherein the homogeneous spreadable conditioning composition has an average spreading velocity at 25° C. that is greater than that of the ester alone.
2 . The homogeneous spreadable conditioning composition of claim 1 , wherein the branched hydrocarbon and the ester are independently not derived from petroleum.
3 . The homogeneous spreadable conditioning composition of claim 1 , wherein the ester is selected from the group consisting of: glyceryl triheptanoate and heptyl undecylenate.
4 . The homogeneous spreadable conditioning composition of claim 1 , wherein the branched hydrocarbon has a main hydrocarbon chain having Y carbon atoms and Y is 12 and X is 15.
5 . The homogeneous spreadable conditioning composition of claim 1 , wherein the branched hydrocarbon is hydrogenated farnesene.
6 . The homogeneous spreadable conditioning composition of claim 1 , wherein the ester is vegetable-derived.
