Rozetta, I got a similar response when I wrote to question the formula change, a very prompt, semi-lengthy educational message about silicones and why Renpure uses them in their products. In fact, it had the exact excerpts you posted, making me think now that I simply got a form response. Hopefully a real human read my original message... I did reply back explaining CG method and why I choose not to use non water soluble silicones in my hair. Renpure didn't bother with another response after that. Disappointing.
