Functions
Weak Preservative
Keeps your product from growing bacteria, mold, or yeast. Without these, that jar of cream becomes a petri dish in about a week.
Skin Conditioning Agent
A catch-all term for ingredients that improve how skin looks and feels — softer, smoother, more supple. The workhorse behind most moisturizers.
Draws water to skin
Locks in moisture
Strengthens skin barrier
Traditional Use
Synthesized from petroleum or glycerin in the early 20th century, this humectant was adopted by the cosmetics industry as a cheaper, more stable alternative to glycerin for moisture retention in skincare products.
