2.1 No segregation

2.2 Maintain the effectiveness of various substances

3. How will the cream texture come out? I want a soft, smooth, light texture that absorbs quickly.

Ask for more information, SPF Protect Ultra ™ II if put in the amount of 30 % -> SPF =90 PA++++

If wearing 15% SPF =50 PA ++

1. If I add 10%, has the company ever measured the SPF PA value?

2. If I put MatteSilica 5S™ to reduce oiliness, viscous and easy to spread, will it affect the action or efficiency of the Active ingredients mixed in the Oil phase?

such as MSH White ™ ( Undecylenoyl Phenylalanine), WhiteCumin ™ ( Tetrahydrodiferuloylmethane)

,Hi- GlabridinLicorice Extract (Glabridin 40%) , TXC ™ ( Cetyl Tranexamate HCl )

3. Cases affecting efficiency Is there any that help reduce it? Is it easy to spread without disturbing the performance?

thank you very much

hello


It is not recommended to add too many active ingredients or oils in the sunscreen formula. It will make it gooey and unusable.


Applying sunscreen at various rates And it's difficult to compare it to the SPF value because other components, especially the emulsion system, are very important to the sun protection efficiency. Therefore, it is necessary to send the actual measurement only if you want to know the correct sunscreen value.


MatteSilica 5S does not affect the performance of the active ingredients in the formula, but in sunscreen products. It is not advisable to add high amounts of active ingredients.
