Cosmetics Formulation Development

I want to make a lotion to reduce irritation. I don't know if the formula needs to be adjusted in any way.
1. Betaglucan 5%

2. Hi-LiconeA™ Licorice Extract (Licochalcone A 20%) 0.3%

3. MOIST72 ™ 2%
4. Skin Barrier Cream Base ( Emulsifier Free) 20%
eq. DI Water TO 100%

I would like to ask the following question.
1. Is the texture difficult to spread? If the lotion is difficult to spread, what should I do to fix it?
2. Does this formula help reduce irritation, dryness, redness, and itching?
3. How old can young children be?

thank you

Please help the staff.

Waiting for an answer.

Thank you.

I would like to thank the staff because I used to buy the bass version and use it alone.

When mixed, it will definitely become watery and may separate. You have to shake it before using.
