Cosmetics Formulation Development

Ask the staff if you want to mix the formula as follows. 1.(oil A+oil B+oil C+oil soluble extract D+oil soluble extract E) 60% 2. ( น้ำกลั่น + water-soluble extract A + water-soluble extract B + water-soluble extract C ) 39.5% 3. สารกันเสีย (Mild Preservative ECO) 0.5 % Question 1. Can the formula be done without having to enter? Emulsifier to avoid irritation. 2. If the oil is incomplete (which may be caused by the use of various oils in the formula), can it be continued by shaking it together? 3. If you want to use SkinLipid™ dissolves in oil and is not used. Emulsifier formulas can be mixed or not because I'm afraid SkinLipid™ will solidify at normal temperature 4. Glycerin If used in large quantities, can it cause irritation to the skin or not? And what percentage of staff recommends using it to be able to benefit from? Glycerin as much as possible. 5.Staff, do you have any other suggestions? Thank you.

Hello, 1. Yes, as the members understand. The formula is stratified. Shake well before use. 2. Yes. 3. It is hard. It will form a sediment. Use Skin-mimic can be substituted. 4. Recommend 5% should be enough. Using high amounts can irritate the skin.
