    Just an FYI, this is a cosmetic forum so car polish discussions aren’t typically relevant. 
    That said, you’d also need to provide more information. Silicon emulsion 60% doesn’t give any indication really to how much you’ve used, considering you’re using units of cc and litres aside from that.
    I’d guess that you haven’t got enough of, or a suitable enough, surfactant/dispersing agent to create a stable emulsion with water and your silicon emulsion 60%. Have you determined which phases are separating?

    Thanks Ben, You right my question is not relevant on regards to this forum. But We all are chemical guys here so i though we learn from each other experiences

    Emulsion is going to separate after few hours, when we shake the bottle it gets settle , but after few hours it again gets separate. I am using silicon emulsion 220cc np-9 150cc tea 2 cc and water to complete 1 liter along with fragrance and color

    I’m guessing the ‘Silicone Emulsion 60%’ is the type as sold by, e.g., Mistralni here in the UK? https://mistralni.co.uk/products/silicone-emulsion-60pct
    I have no idea why it would be separating in that case. It’s described as completely miscible in water, the Tergitol/NP-9 is water soluble as is TEA.
    Talk me through your choices for the chemicals you’ve chosen. I’m guessing silicone emulsion is for water repellence, NP-9 for wetting, TEA for adjusting pH maybe? Fragrance and colour should be miscible enough also, especially with NP-9 present so I’m confused as to what’s separating. Have you tried isolating the two fractions and examining them more closely?

    You  should use np6 it’s best emulsifier for silicon
