BANANA GEL [PDF]

Journal of General Physiology, 1922
The conditions for the formation of gels from banana extracts were studied. Gels were obtained with extracts more alkaline than pH 7.0 with very small quantities of calcium, strontium, and barium salts, the gel formation with these salts decreasing in the indicated order.

Individual sol-gel microencapsulation of benzoyl peroxide and tretinoin enables controlled release onto the skin

Heliyon
A combination of benzoyl peroxide (BPO) and tretinoin is recommended for treating acne; however, concurrent administration can be irritating, and coformulation is prevented by BPO-mediated oxidation of tretinoin.
