Glycolic Acid (Liquid) – 70% Solution

Description

Glycolic Acid Liquid is a high-performance Alpha Hydroxy Acid (AHA) naturally derived from sugarcane, known for its exceptional exfoliating and skin-renewing properties.

With its small molecular size, Glycolic Acid penetrates deeply to dissolve dead skin cells, unclog pores, and stimulate collagen production. These characteristics make it a key ingredient in chemical peels, toners, serums, and exfoliating cleansers.

Ideal for formulating products that target dullness, uneven texture, fine lines, and acne-prone skin, this liquid AHA helps reveal a smoother, brighter, and more youthful complexion.

• For leave-on products, 1–10% is typical.
• For rinse-off peels, up to 20% may be used with proper pH adjustment.

pH Adjustment: Glycolic acid is highly acidic (pH ~1.5). Use a neutralizing agent like Sodium Hydroxide to adjust your final product to a skin-safe pH of 3.5–4.5.

Compatibility: Avoid combining with strong actives like retinoids or vitamin C unless professionally formulated. Glycolic Acid can increase skin sensitivity.

 

Safety Guidelines

Patch Test: Always perform a patch test before full application, especially for higher concentrations.

Sun Protection: Glycolic acid increases photosensitivity. Advise users to apply sunscreen daily when using products containing AHAs.

Storage: Store in a cool, dry place away from direct sunlight. Keep tightly sealed to prevent oxidation.
