  • How much silicones to use (liquid and solid bar conditioner)?

    Formulas from swift crafty monkey suggest 2%
    cyclomethicone and 2% dimethicone for both LIQUID and SOLID BAR conditioners.


    The confusion is:

    1. With LIQUID, about 10 grams of product is used
    on shoulder-lenght long hair (at 4% combined silicones, this means 0.4g total
    silicones are applied to the hair). Im assuming that is enough for achieving
    the effects these ingredients are supposed to achieve? Is 2% + 2% a high amount
    in your experience? Is it a low amount?


    2. With SOLID
    BAR, the same person will rub off about 1 gram of the bar onto his/her head. If
    again 2% + 2% of each silicone are used, then only about 0.04 grams of total silicones
    were transfered from the bar to the head/hair. This quantity seems insufficient
    for any effect, but I am guessing.


    By this logic, if
    2%+2% in liquid was an average and good amount to use, then the bar would need
    to be 20% + 20% to achieve the same quantity transfered.

    What is the minimum % of cyclo and dime respectively, that is
    usually used in liquid conditioners to achieve an effect? 2%? 0.5%? 1%? 0.2%?
    Is a
    co-ingredient required at that level (I’ve read that polyquat 10 and cationic
    guar aid with deposition)? Do you have any data on quantities required
    in a bar conditioner as well?

    I have so far attempted a 10% dimethicone bar conditioner. The product was
    stable, but judging if there was any effect is hard, so I turn to you.
