Hello

1) from formula and ratio Glycerin e Which one should I buy? ( Double Glycerin or X Glycerin e ?) if changed to MOIST24 will provide a non-greasy texture. Better performance or not?

You can choose to use all 3 X- Glycerin and MOIST24 outperforms Glycerin is normal, but the price is higher. Double Glycerin was not more effective. Glycerin is simple, but has the ability to enter both water and oil. without necessity in this formula because the formula contains water which can be used Glycerin other types can be mixed in anyway ( Double Glycerin Choose when the formula contains only oil. which cannot be used Glycerin other types can be more cost effective)

2) Emulsifier which one is in the formula? Please give advice on which other should be used

because the formula needs to be bi-phase (leave it set, causing separation) not needed. Emulsifier is recommended. thickener that cannot be water-oil bonding, e.g. Xanthan Gum at a low rate (experimental 0.3-0.5%). Xanthan Gum will help capture water. -Oil together for a short time, then when set aside The formula will return to separate the layers as before. The usage rate Xanthan Gum affects how long the formula will stay together, if it is found to be too short (it's not used yet, it's back to classify again) then increase the ratio. Xanthan Gum a little more to Extending the mixing time of the formula before separating again

3) sodium benzoate used as object กันเสีย use it if using Mild Preserved Eco™ (Ethylhexylglycerin) is safer. Is it better to use it?

Yes Mild Preserved Eco is more gentle. but in terms of safety sodium benzoate is considered very secure. Because it has been used for a very long time. including being used in food At present, there is no danger that the FDA's usage rates worldwide have been identified, although synthetic sodium benzoate Derived from Benzoic Acid, but the current production process is very high purity, so it results in very high safety as well.

5) Compared to the barrier cream that the skin recipe produces, this formula has a moisturizing effect. And continued for a long time and soothe the skin less?

formula Skin Barrier Cream recipe listed on ศูนย์รวมสูตร ] ศูนย์รวมสูตร can restore skin moisture much better. But the key problem with the formula is The ingredient cost is too high. Because the ingredients are selected with an emphasis on efficiency. not taking into account the cost If members like such formulas It is recommended to adjust the ingredients. It may reduce the rate of using many items down. Or cut some high-cost items out of the formula?
