Glycols (jaise propylene glycol aur butylene glycol) chhote water-soluble compounds hain jo skincare mein humectants, solvents aur penetration enhancers ke taur par use hote hain. Yeh skin ki texture ko improve karte hain aur dusre ingredients ko dissolve karne mein madad karte hain. Typically ye formulations ka base hote hain aur stability badhate hain.
