Abstract

Implementations of a method of forming a wax ether composition may include: providing a batch of lipids, drying the batch of lipids, and cooling the batch of lipids. The method may also include dosing, with a catalyst, the batch of lipids at 0.1% to 0.3% by weight of the batch of lipids and dissolving the catalyst in the batch of lipids to form a homogenous solution. The method may include adding at least a molar equivalent of a hydrogen donor to the homogenous solution. The method may include sealing and maintaining the homogenous solution and hydrogen donor under atmospheric pressure under reflux until a chemical reaction between the homogenous solution and the hydrogen donor forms a product comprising an ether.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A composition of ethers comprising:
 a product of an etherification reaction of a feedstock comprising a hydrogen donor, a catalyst at 0.1% to 0.3% by weight, and one of jojoba wax esters or  Moringa  oil;   wherein the product comprises 1-nonanol.   
     
     
         2 . The composition of  claim 1 , wherein the hydrogen donor comprises 1,1,3,3-tetramethyldisiloxane (TMDS). 
     
     
         3 . The composition of  claim 1 , wherein the catalyst is a metal halide. 
     
     
         4 . The composition of  claim 1 , wherein the jojoba wax esters or the  Moringa  oil comprise wax esters comprising carbon chain lengths ranging from C24 to C52. 
     
     
         5 . A composition of ethers comprising:
 a product of an etherification reaction of a feedstock comprising a hydrogen donor, a catalyst at 0.1% to 0.3% by weight, and jojoba wax esters;   wherein the product is optically clear;   wherein the product contains no tocopherols or beta carotene therein; and   wherein the product has a higher oxidation stability index than an oxidation stability index of a jojoba wax ester with a substantially equivalent carbon chain length distribution to a carbon chain length distribution of the product.   
     
     
         6 . The composition of  claim 5 , wherein the hydrogen donor comprises 1,1,3,3-tetramethyldisiloxane (TMDS). 
     
     
         7 . The composition of  claim 5 , wherein the catalyst is a metal halide. 
     
     
         8 . The composition of  claim 5 , wherein the jojoba wax esters comprise wax esters comprising carbon chain lengths ranging from C24 to C52. 
     
     
         9 . A composition of ethers comprising:
 a product of an etherification reaction of a feedstock comprising a hydrogen donor, a catalyst at 0.1% to 0.3% by weight, and jojoba wax esters;   wherein the product has substantially equivalent subjective properties to dimethicone; and   wherein the product comprises only carbon, hydrogen, and oxygen atoms.   
     
     
         10 . The composition of  claim 9 , wherein the hydrogen donor comprises 1,1,3,3-tetramethyldisiloxane (TMDS). 
     
     
         11 . The composition of  claim 9 , wherein the catalyst is a metal halide. 
     
     
         12 . The composition of  claim 9 , wherein the jojoba wax esters comprise wax esters comprising carbon chain lengths ranging from C24 to C52. 
     
     
         13 . The composition of  claim 9 , wherein the subjective properties are one of spread, absorbency, feel, gloss, stickiness, slipperiness, amount of residue, silkiness, smoothness, greasiness, or moisturization.
