    The problem is that you are trying to turn a shampoo into an emulsion.
    The whole point of a shampoo is to remove oil. Including Castor Oil in your formula is contrary to the aim of a shampoo. Remove the oil. Then you can remove the emulsifying wax and the Cetearyl Alcohol. If you want a pearlized look, you can use Glycol Stearate. 

    Of course, your level of Aloe is too high and it just gets rinsed down the drain and you don't really need that much coconut milk since it just gets rinsed down the drain too. Finally, your surfactant system (Castile soap & Decyl Glucoside) are going to be very drying and will leave hair in terrible shape.  Overall, you should rethink this and reformulate. Start simple. You don't need 13 ingredients to make a shampoo. Start with 5 or 6.

    Wow what a rollercoaster.

    1. this is not organic. Emulsifying wax contains polysorbate 60.
    2. you don't have any of your phases defined but usually you do not homogenize shampoos or cleansers.

    3. Take potassium sorbate out. It only works at ph<5.5 which your product is surely not at with castille soap

    4. Take out castor oil, it will only impede performance. If you want it for claims keep at 0.01% or less. I'd say the same for coconut milk

    5. Probably best to mix the fragrance in with some of  your decyl glucoside then add.

    Why are you including the cetearyl alcohol and emulsifying wax at all? 
    Thank you so much @Perry ;
    i will try and reformulate

    for the surfactant system what can i add to make moisturizing shampoo for kids 

    The reason i use castor oil is to provide moisturize effect to the shampoo, what can i use to provide moisturizing effect

    My ... this is one hot mess.  @Rucrasha ... try this:

    Water, Aloe Vera Leaf Juice, Coconut Water, Castile Soap, Sucrose Cocoate, Xanthan Gum, Fragrance, Preservative.

    This is going to have a pH of about 9.0+, so it's not really a great shampoo for children ... will sting the eyes, but you may be able to get an Organic Certification on it.

    Organic doesn't necessarily mean good or better, so don't confuse Organic certification with a superior product.  You can make a much better, tear-free NPA certified shampoo for children.
