alcohol

Description

Alcohol, specifically ethanol or isopropyl alcohol, is a widely used ingredient in skincare and cosmetic formulations. This versatile compound serves multiple purposes in product development and application. Primarily, alcohol acts as a solvent, facilitating the dissolution and blending of other ingredients. It also functions as a preservative, inhibiting microbial growth and extending product shelf life.

In skincare, alcohol is valued for its rapid evaporation properties, which create a cooling sensation upon application and promote quick absorption of active ingredients. It can temporarily tighten pores and reduce oiliness, making it beneficial for acne-prone or oily skin types. However, excessive use may lead to dryness and irritation, particularly in sensitive or dry skin.

Alcohol's astringent properties make it effective in toners and cleansers, helping to remove excess oil and debris. In hand sanitizers, high concentrations of alcohol (typically 60-95%) effectively kill harmful microorganisms. Despite its benefits, alcohol can potentially disrupt the skin barrier if used excessively or in high concentrations. Therefore, its inclusion in skincare formulations requires careful consideration of concentration, skin type, and overall product purpose.
