Description

Lactic Acid is a concentrated aqueous solution of lactic acid, an alpha hydroxy acid (AHA) commonly used to improve the look of dullness, uneven tone, and rough texture through gentle surface exfoliation.
Compared to glycolic acid, lactic acid is generally perceived as milder, and it also contributes to skin comfort and hydration support because it is part of the skin’s natural moisturizing factors. This makes it a popular choice for formulas designed for smoother texture with less sting.
This 88% grade is typically used as a manufacturing concentrate. It allows formulators to dose accurately, then fine-tune the final pH for the intended performance and skin feel.

FEATURES

Gentler AHA exfoliation – supports smoother-looking texture and a more even appearance.
Hydration support – can contribute to improved skin feel versus more aggressive acids.
Flexible dosing – 88% concentrate makes it easy to hit target active levels.
pH adjuster – also useful for lowering pH in water-based systems.

BEST FOR

Exfoliating toners
Gentle resurfacing serums
Body lotions for rough texture
Brightening routines
Rinse-off AHA cleansers
pH adjustment in emulsions and gels

Formulator tip: Treat 88% lactic acid as a concentrate. Add into the water phase with mixing, then adjust and verify pH (immediately and again after 24 hours) because some formulas drift after neutralization.

FORMULATION GUIDELINES

INCI	Lactic Acid (and) Water
Type	Alpha Hydroxy Acid (AHA) exfoliant concentrate / pH adjuster
Solubility	Water soluble
Active Content	88% Lactic Acid (as supplied)
Use Rate	Depends on target active level and final pH. Common finished-product levels: 2–10% (leave-on) and 3–15% (rinse-off), subject to your formulation goals and compliance requirements.
Best Phase	Water phase (add with mixing, then pH adjust)
pH Compatibility	Works in acidic systems. Typical finished-product pH is often set around 3.5–4.5 for exfoliation-focused products, or higher when used mainly for pH adjustment.
Temperature Tolerance	Stable during processing. We recommend adding below 40–50°C when possible, especially if your formula contains other heat-sensitive components.
Pro Tip	Lactic acid can thin or haze some polymer gels at low pH. If your viscosity collapses, check polymer acid tolerance and electrolyte sensitivity. For smoother sensory, many formulators use lactic acid in buffered systems and avoid overly low pH unless a strong exfoliation profile is required. Handle as a strong acid concentrate: use suitable PPE, add slowly, and avoid incompatible metals during batching.
Appearance	Clear to pale yellow liquid
Stability Notes	Final pH impacts stability, preservative efficacy, and polymer compatibility. Validate pH drift, clarity, and viscosity over time.
Storage	Store tightly closed in a cool, dry place, away from heat and moisture.
