Cosmetics Formulation Development

I'm sorry to ask for advice. Make a shower gel around September. At that time, there were a lot of bubbles, foaming up, and coming this month, the bubbles are not foaming up, the texture remains but it seems that only the viscosity of n70 and other rms are left. Please advise. Thank you.
