    It’s an emulsion made of cationic ingredients. Its not good or bad. It’s used for hair products a lot due to conditioning properties.

    Examples of cationic ingredients: BTMS-50, centrimonium chloride and polyquats. Be careful when mixing it with anionic or amphoteric  (an emulsion might break).

    @ngarayeva001 thanks a lot. I appreciate your help 
    btms-50 is the one. I will stay away from it.

    @ngarayeva001 So what else would be good for a hair conditioner? What would you suggest?

    Couldn’t you use a chelating agent?

    @Dtdang I am not saying to stay away from it. It’s pretty useful if you are making a hair mask or hair conditioner, all I am saying you need to be careful when adding other ingredients because if you mix it with something anionic or amphoteric where pH is higher than 7 you will destabilize your emulsion.

    @Jdawgswife76 chelating agents are used to bind electrolytes in your water, which is crucial if you are working with electrolytes sensitive ingredients. Chelating agents are not conditioners. I gave several examples of conditioning ingredients above.

    That is true: acid + alkaline -> salt + h2o

    A cationic emulsion can be made with

    4% Cetrimonium Chloride on an ACTIVE ingredient basis
    2% cetearyl alcohol

    or just use premade BTMS.

    Isn’t it better to have both BTMS and centrimonium chloride is together?

    Yes, but Cetrimonium Chloire (CETAC) often reduces viscosity, unless additional fatty alcohols are added.
    Also, there are regulations that limit CETAC % in some countries.

    I agree it does decrease viscosity significantly  but it makes the product better. I am still experimenting with it. The texture is nice if you add enough oils, but performance is worse.

    It’s all how you shape the formula, I have a light conditioner with fatty alcohols, GMS and few emollients which thicken up nicely with the addition of CETAC 30%.

    @Chemist77, I have question to you that when I reduce the percentage of oil phase, do I need to reduce or to increase the percentage of emulsifier (same emulsifier)?

    Thanks in advance.

    It is all very subjective, but just don’t overkill.

    I am trying to make an all-natural conditioning bar. Can you suggest any natural ingredients that may give a similar performance?

    @J4ckbird - Similar performance to what?

    The reality is that conditioners aren’t natural so there is nothing in nature that will give similar performance. If you’re not going to use the best available ingredients (synthetic conditioning agents) you can’t expect the same performance.

    The best you can try is Coconut oil or Palm oil or something that these non-natural conditioning agents are made from. It won’t work as well but it might work well enough.

    @J4ckbird, I love natural products but maybe 90% natural s the rest maybe non-natural.
    here is simple natural conditioning bar. 
    Bmts-50
    cetyl alcohol 
    babassu oil or coconut oil ( I like Babassu Oil)
    shea butter or cocoa butter 
    natural oils you like 
    apricot oil
    essential oil (you like)

    If you love chocolate, use cocoa butter and sweet orange essential oil
    it smells great

    What are some good conditioning agents you would recommend?  Also i made a body wash with castile soap because my SLSL HAD NOT came in yet and it turned out wonderful only it left the skin feeling really to clean and not moisturized and i used jojoba,  coconut  oil and some other ingredients i would have to pull up my formula sheet but just out of curiosity if i wanted to make fast non emulsive body wash with Castile soap do you have any recommendations?

    Castile soap is a soap. It will not be moisturizing, and you can’t make non-drying body wash with it.
