ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention deals with the certain novel esters derived from specific cyclic ether containing alcohols. These products have surprising hydroalcoholic solubility and a very desirable skin feel, making them ideal candidates for use in products like after shave preparations.
2. Description of the Art Practices
Fatty alcohols have been known for many years, primarily for their liquidity at high molecular weight. Over the years there have been a number of derivatives patented.
U.S. Pat. No. 4,868,236 to O'Lenick discloses a Guerbet citric ester and polymers thereof useful in plastic lubrication.
U.S. Pat. No. 5,488,121 issued Jan. 30, 1996 to O'Lenick teaches that esters based upon a Guerbet acid and Guerbet alcohols have surprisingly good liquidity.
None of these materials offer the hydroalcoholic solubility and unique dry skin feel as do the compounds of the present invention. Both of these desirable properties are a direct consequence of the proper selection of the cyclic ether containing alcohol and the proper fatty acid used to make the ester.
THE INVENTION
3. Objective of the Invention
It is the objective of the present invention to provide novel ester compositions, based upon (a) fatty acids and (b) an ether containing alcohol, which when both present in the same molecule result in an ester that exhibits outstanding hydroalcoholic solubility and excellent skin feel, heretofore unattainable.
It is another objective of the present invention to provide a process for conditioning skin by applying an effective conditioning concentration of the novel ester compositions, based upon (a) fatty acids and (b) a novel ether containing alcohol.
Other objectives will become apparent reading the present teachings.

DETAILED DESCRIPTION OF THE INVENTION
The compositions of the present invention are made by the esterification of a mixture of two novel ether alcohols conforming to the following structures:
(a) a six member ringed ether alcohol
and
(b) a five member ringed ether alcohol
The mixture is commercially available and the ratio of (a) to (b) ranges from 0.8:1 to 1.0 to 0.8, with a ratio of 1:1 being most desired.
with a fatty acid conforming to the following structure;
