Hello, this formula has the following problems: 1.
retinyl palmitate must be soluble in oil But there is no oil in the formula to help dissolve it. 2.
Silk Cream Maker at a rate of 1% is not enough because it is harder to integrate than the usual formula because
N-Acetyl Cysteine which has a low pH. (in this case, it must be considered
Gel Maker as a helper. as you
Gel Maker recommended, including possibly increasing the usage rate of Cream Maker.) The solution is as follows.
Gel Maker eg
Pro Polymer checked from history Found that it was bought in 2017, not sure if it's still there. If it's still there, check if the powder is intact. no physical change if so To be tested, add at the rate of 1.0% into the formula by gently scattering and blending together. Should be able to solve the problem if not
Gel Maker left, recommend using
Xanthan Gum or
Pro Polymer optional in 1.0% rate, sprinkle into the formula while However, the problem of
retinyl palmitate that cannot Soluble is also in the formula. May be a hindrance to use it. If re-mixing, it is recommended to adjust by increasing the proportion of oil. to act to dissolve
retinyl palmitate and adjust the mixing procedure. By creating a cream until complete (mix separately the water part, the oil part, then add the oil part to the water part. while blending continuously) as well as adjusting the viscosity of the finished formula (adding
Gel Maker adjust the thickener) and then gently sprinkle.
N-Acetyl Cysteine into the cream. Stir until dissolved. In the last step
