Abstract
This invention relates to the use of aminofunctional silicone microemulsions to make optically clear hair conditioning compositions. More particularly this invention is directed to optically clear hair conditioning compositions comprising an aminofunctional microemulsion, at least one long-chain quaternary amine salt, and water. The optically clear silicone compositions of this invention are useful in the hair care industry, especially as hair conditioners.
