Lactic Acid 88%

• Supplied at 88% concentration in liquid form for precise dosing flexibility across a range of formulation types
• Functions as a pH adjuster, humectant contributor, and cosmetic exfoliation ingredient
• Compatible with creams, lotions, cleansers, chemical peel formulations, and hair care products
• Naturally occurring AHA — supports clean and naturally derived positioning when desired
• INCI: Lactic Acid

Intended Use

Intended as a post-added ingredient for cosmetic formulators developing exfoliating skincare, pH-balanced cleansers, body care, or conditioning hair care products. Not a finished product — requires incorporation into a complete formulation at appropriate usage levels.

Customization Notes

• Formulators should determine final concentration based on target pH, product type, and intended cosmetic use
• Pairs well with other AHAs (glycolic, citric, malic) in multi-acid exfoliation blends
• Suitable for inclusion in products positioned around the appearance of smoother, more refined-looking skin

Option 1: Standard Formulation Incorporation

1. Determine the target lactic acid percentage for your finished product based on the product type (leave-on, rinse-off, or cleanser).
2. Add the concentrated lactic acid solution during the cool-down phase of your formulation, stirring slowly and evenly to incorporate.
3. Measure and adjust the final pH of your product to the desired range — lactic acid will significantly lower pH, so buffer as needed.
4. Test the completed batch for stability and sensory feel before moving to packaging.

Option 2: Multi-Acid Blend Development

1. Calculate usage rates for each AHA you plan to combine — lactic acid pairs well with glycolic, citric, and malic acids for a balanced multi-acid profile.
2. Add lactic acid and complementary acids to the water phase during cool-down, blending thoroughly.
3. Adjust pH to the target for your product format — a toner may require a different range than a rinse-off peel or mask.
4. Evaluate the finished multi-acid formulation for clarity, texture, and skin feel before scaling.

Option 3: pH Adjustment and Conditioning Use

1. Use small, measured amounts of lactic acid to lower and fine-tune the pH of existing formulations — such as lotions, conditioners, or cleansers — that require precise pH control.
2. Add incrementally, stirring after each addition, and test pH until the target value is reached.
3. The humectant properties of lactic acid will contribute a smoother, more conditioned feel to the final product.
4. Document usage rates for batch consistency and reproducibility across production runs.
