Method of preparing microemulsions

A process for preparing a transparent microemulsion comprising:

• (a) preparing a blend of silicones comprising a low silicone content microemulsifiable silicone having the formula:
• M(R.sub.a Q.sub.b SiO.sub.(4-a-b)/2).sub.x (R.sub.c SiO.sub.(4-c)/2).sub.y M
• wherein R is a hydrocarbon or hydrocarbon radical having from 1 to about 6 carbon atoms, Q is a polar radical having the general formula --R.sup.1 HZ, wherein R.sup.1 is a divalent linking group bound to hydrogen ,and a radical Z wherein R.sup.1 is comprised of carbon and hydrogen atoms;
• carbon, hydrogen and oxygen atoms, or carbon, hydrogen and nitrogen atoms;
• and Z is an amino containing radical having the formula:
• --N(CH.sub.2).sub.z (CH.sub.2).sub.zz NH
• wherein z is one or greater and zz is zero or greater subject to the limitation such that when zz is zero Z has the formula:
• --NH(CH.sub.2).sub.z NH.sub.2
• wherein z is one or greater;
• a ranges from about 0 to about 2, b ranges from about 1 to about 3 such that a+b is less than or equal to 3, and c is a number in the range of from about 1 to about 3;
• and x is a number in the range of from 1 to about 20 and y is a number in the range from about 20 to about 800, and M is a silicone endstopping group;
• (b) adding a surfactant having a phase inversion temperature ranging from about 45.degree. to about 95.degree. C.;
• (c) heating said silicone and said surfactant to a temperature ranging from about 45.degree. C. to 95.degree. C. wherein the temperature is a temperature below the phase inversion temperature of the surfactant;
• (d) adding part I water;
• (e) adding an acid;
• and
• (f) adding part II water, whereby said microemulsion has an ASTM D871 haze number below about 150.
