Anti-Acne Treatment Cream with 2% Salicylic Acid
O-0057
Clear pimples and purify your skin with this facial lotion enriched with salicylic acid. Carbopol®* Ultrez 30 polymer offers good viscosity in combination with xanthan
gum in the presence of 2% salicylic acid and 5% of an electrolyte-containing extract, at pH 4. Glucamate™* SSE-20 and Glucate™* SS emulsifiers impart good
emulsion stabilization. Schercemol™* NGDO ester provides emolliency with high spreadability and light sensory while Glucam™* E-20 humectant imparts
humectancy to avoid dryness often associated with salicylic acid. Japanese green tea extract reduces skin irritation imparted by the acidic active.
