Cocamidopropyl Betaine

★ 9.4

The absolute legendary pioneer of low-pH skin washing across Malaysia and Southeast Asia. COSRX completely dismantled old-school high-pH alkaline cleansing loops by launching this physiological pH 5.5 wash. It utilizes an ultra-mild, non-stripping anionic-amphoteric surfactant matrix (Sodium Lauroyl Methyl Isethionate and Cocamidopropyl Betaine) to lift surface dirt softly. It leaves the critical moisture lipid bricks completely untouched. Packed with **0.5% Styrax Japonicus botanical extract** and natural **Tea Tree Oil**, it targets acne bacteria corridors during washing, rinsing away to leave a thoroughly clean, perfectly balanced fresh satin baseline.

★ 8.8

A cult-classic physical bar soap that elegantly dodges the severe alkaline damage of traditional bars. By utilizing Cocamidopropyl Betaine (a gentle liquid surfactant) in a solid matrix, it achieves a low pH that respects the acid mantle. The activated charcoal acts as an incredible physical sponge for heavy midday sebum, while the high dosage of raw honey and glycerin ensures the skin is conditioned during the wash phase.

★ 9.2

A highly unique, dark-tinted low-pH gel cleanser. It steps away from standard alkaline soaps by using Ammonium Laureth Sulfate (a milder, large-molecule alternative to SLS) combined with Coco-Glucoside for a gentle, non-stripping lather. The activated charcoal acts as a mild absorbent for surface pollutants, while the staggering complex of 10 different berry extracts provides a massive antioxidant bath to neutralize environmental free radicals during the wash phase. It leaves the skin exceptionally soft rather than squeaky clean.

An incredibly gentle, sulfate-free gel cleanser. Unlike the Foam or Deep Cleansing versions in the Aiken line, this formula entirely bypasses alkaline soaps. It relies on extremely mild amino-acid surfactants (Sodium Cocoyl Glycinate) and a massive Glycerin base to melt away surface impurities without stripping the delicate acid mantle. It is the absolute optimal choice for broken or compromised barriers.

★ 8.8

A highly sophisticated, pH-balanced gel-cream cleanser. It utilizes a robust blend of mild surfactants (Cocamidopropyl Betaine, Sodium Cocoyl Alaninate) alongside a low dose of Ammonium Lauryl Sulfate to effectively strip heavy oils without shocking the acid mantle. Salicylic Acid (BHA) dives into the pores to clear congestion, while the heavy lipid matrix of Ceramides, Calendula, and Sunflower oil completely prevents the post-wash tightness typically associated with acne cleansers.
