Abstract
The present invention relates to specific compositions made by alkoxylation of crude guerbet alcohol mixtures that contain between 15% and 50% lower molecular weight alkoxylated alcohols. The lower molecular weight alcohols are the raw material alcohols used to make the guerbet. Compositions containing this specific bi-modal distribution have unique emulsification properties.
Claims18
A bi-modal emulsifier composition which comprises:
- (a) between 10% and 50% by weight of an emulsifier which conforms to the following structure:
- CH3(CH2)n−O—(CH2CH2O)a(CH2CH(CH3)O)b—(CH2CH2O)c—H
- wherein;
- n is an integer ranging from 5 to 19;
- a, b, and c are independently each integers ranging from 0 to 20, with the proviso that a+b+c be greater than 5;
- and
- (b) between 90% and 50% of an emulsifier which conforms to the following structure:
- wherein;
- y is an integer ranging from 5 to 19, and is equal to n;
- x is an integer ranging from 3 to 17 with the proviso that x=y+2
- a, b, and c are independently each integers ranging from 0 to 20, with the proviso that a+b+c be greater than 5.
