TLDR Chemical hair removal can cause skin irritation and other issues, but natural alternatives are being explored.
The document discussed temporary chemical depilation, which used chemicals like thioglycolates to break down hair keratin, facilitating easy hair removal. The depilatory formulas included components such as surface active agents, binders, alkaline pH adjustors, and hair penetrators to enhance efficiency. However, issues such as skin irritation, dark points from remaining hair, and hydrogen disulfide gas formation were noted. Alternatives like papain and eflornithine were mentioned for hair removal, with a focus on finding natural-based substances to reduce hair growth, despite challenges with compound instability in alkaline environments.
