Cosmetics Formulation Development

Hello, I'm going to make a whitening and moisturizing face serum. So I want to disturb you to see if the formula is appropriate or not. especially substances that belong to the group of whitening which has multiple characters in the formula And I want to bother you about which binder to use to make it suitable for making serum because the formula contains oil. Aque 73.1000 Nicotinamide 1,3- Propanediol (Natural) 5.0000 n-acetyl glucosamine 4.0000 Activated Resorcinol™ 1.0000 Pantothenic Acid 2.0000 Microcare PHC 1.0000 Pyridoxine Hydrochloride 1.0000 Allantoin 0.5000 Sodium Hyaluronic Acid 0.4000 Glycerin e 0.3000 Disodium EDTA 0.2000 Olive Oil (Extra Virgin) 2.0000 Sweet Almond Oil (Refined) 3.0000 Phenylethyl Resorcinol (eq. Sym-White™ ) 0.5000 (there is still missing binder in the formula) Thank you.

Hello, this formula has the following problems: 1. Use Phenylethyl Resorcinol and Activated Resorcinol which is useless. Choose to use only one. That's enough. If using both of them, there is a chance of skin irritation too. 2. There should be ActiveProtec OX 1% to help make the formula more stable. Combine water-oil in this recipe, recommend Satin Cream Maker 1.5% + Xanthan Gum 0.5 % reasons for filling Xanthan Gum 0.5% because it helps stabilize formula with Phenylethyl Resorcinol or Activated Resorcinol
