Blemish Control cream formulation
I want to develop blemish control cream & I want to use Salicylic acid so I want to know that can we add Salicylic Acid in Oil Phase (Melting point of Salicylic acid is 158 to 161°C) ?
And one more thing I want to know that if I want to use salicylic acid so which thickener I can use ?
If I will use xanthan , it will not give good creamy structure. & carbomer we can not use because of pH issue.
Which another thickener we can use for the Blemish control cream.
pH of Blemish control cream is generally 3.8 to 4.8 ?
