5. Willow Bark Extract: A source of natural salicylic acid-like ingredients that enhances skin cell turnover by promoting exfoliation, resulting in a general improvement in the appearance of the skin and a smoothing effect with accompanying reduction of fine lines and wrinkles. It also exhibits antimicrobial capabilities and can contribute to the preservative efficacy of formulas.
6. Propanediol 1,3: A natural and renewable substitute for propylene glycol that increases hydration when used in hair and body products. It has a light, non-sticky skin feel and is a good solvent for hard-to-dissolve ingredients as well as botanical extracts.

Its recommended to undergo stability and microbial testing to ensure adequate preservation and to carefully consider the choice of preservatives for personal care formulations.
