I intended to dilute the solution using distilled water as the solvent. Which combination of preservatives would you suggest adding?

What would you recommend for keeping skin hydrated and avoiding dryness?

I appreciate you taking the time to provide suggestions and corrections.

I thought this combination of preservatives would help a concentrated foaming cleanser be effective if diluted by 80%. Thank you for your help and time. If I understood correctly, this would be the formulation:
Phase A:
Water - 70%
Glycerin - 5%
Cocamide DEA - 2%
Disodium EDTA - 0.1%Phase B:
Cocamidopropyl Betaine - 8%
Sorbitol - 4%
Disodium Laureth Sulfosuccinate - 2%
Allantoin - 0.5%
Sodium Chloride - 0.5%Phase C:
Fragrance - 0.5-0.8%
Methylchloroisothiazolinone - 0.035%
Methylisothiazolinone - 0.015%Total: 100%
Can I still use lactic acid and sodium hydroxide to adjust the pH?
