Adding Phytosphingosine to a Glycol-Based Serum
Yes, you can add Phytosphingosine (90% Purity) to a serum formulation that contains glycol but no oil. According to the product information, Phytosphingosine (90% Purity) is soluble in organic solvents like glycol. You can blend it with the glycol in your formula before incorporating it into the rest of the serum.
However, Phytosphingosine SA is not suitable for a serum without oil. Its description specifies that it requires an oil like Octyldodecanol for proper dissolution and effectiveness, along with specific heating steps for the oil phase.
