Ingredients Highlights

• Glycerin (10%): A hydrophilic organic compound widely recognized as a highly effective humectant. Helps attract and retain water to support hydration and comfort. Beyond surface moisturization, glycerin can penetrate the skin barrier and help maintain hydration in deeper layers for longer-lasting softness.
• Cleansing Surfactants (11.5% blend): Ingredients designed to break down and emulsify oils and debris, suspending particles so they rinse away easily with water. Surfactants may be classified as cationic, anionic, non-ionic, or amphoteric depending on the ions they form in aqueous solution—helping formulators balance cleansing performance with skin feel.
• Sodium PCA (1%): A humectant derived from glutamic acid obtained from sugarcane molasses. It occurs naturally in the skin and helps reduce water loss, supporting improved hydration and a more comfortable feel.
