From PP: "Best results will be obtained from using ingredients with a MW of less than 300. Generally, the lower the MW, the better the absorption. Most compounds with a MW of less than 300 will be absorbed at a 30-40%."
In summary, the smaller the Molecular weight, the better the transdermal absorption.
