Lactic Acid 80% – 100g

Lactic Acid 80% – 100g – Powerful pH Control with AHA Benefits – For Smoother Skin & Better-Balanced Formulations – Gentle AHA Exfoliation for Smooth, Radiant-Looking Skin

Quick Overview

Lactic Acid 80% – Excellent Grade is a high-purity, fermentation-derived lactic acid solution designed for cosmetic, personal-care, and formulation applications. It contains 80.2% lactic acid with 97.8% L-isomer purity, making it a versatile ingredient for pH adjustment, skin exfoliation, moisturization, and formulation optimization.

Description

Lactic Acid 80% is a concentrated, water-based solution of L-(+)-Lactic Acid, a naturally occurring Alpha Hydroxy Acid (AHA). Produced through fermentation, it is supplied as a light yellowish to colorless, syrupy and hygroscopic liquid with a mildly acidic odor.

In cosmetic formulations, lactic acid is valued for its multifunctional properties. It can be used to lower and fine-tune formulation pH, support smoother-feeling skin through controlled exfoliation, and contribute to the moisturizing properties of skincare products.

Its excellent versatility makes it suitable for a wide range of formulations, including shampoos, conditioners, cleansers, creams, lotions, toners, serums, and exfoliating products.

Key Functions

• pH Adjuster – Helps lower and precisely control formulation pH.
• AHA Exfoliant – Helps loosen and remove dead surface skin cells when appropriately formulated.
• Humectant – Helps support moisture retention in suitable formulations.
• Skin Smoothing Agent – Supports a softer and smoother skin feel.
• Formulation Optimizer – Helps achieve the desired acidic pH range in personal-care products.
• Hair-Care pH Adjuster – Useful for adjusting shampoos and conditioners to an appropriate acidic pH.

Technical Data

Recommended Usage

The required amount depends on the intended purpose, formulation type, and desired final pH.

• For pH adjustment: Add gradually to the formulation while monitoring pH.
• For shampoos and conditioners: Primarily used as a pH-adjusting ingredient.
• For skincare: Can be incorporated into properly designed AHA formulations for exfoliating and skin-smoothing benefits.
• For lotions and creams: Can assist with pH adjustment and provide multifunctional skin-care benefits.
• For exfoliating products: The final lactic acid concentration and pH should be carefully controlled.

Because this is an 80% concentrated solution, it should generally be incorporated carefully rather than used directly.

Formulation Tip

For shampoo and conditioner formulations, Lactic Acid 80% is primarily valuable as a pH adjuster rather than a thickener. Add it gradually and measure the pH after each addition.

A lower pH can affect the viscosity and performance of surfactant systems, so the final formulation should always be evaluated for pH, viscosity, clarity, preservation, and overall stability after adjustment.

Safety & Precautions

• Lactic Acid 80% is a concentrated acidic material and should be handled with appropriate care.
• Wear suitable gloves and eye protection when handling the concentrated ingredient.
• Avoid direct contact with eyes and prolonged skin contact.
• Do not apply the concentrated 80% material directly to skin.
• Add gradually to formulations while monitoring pH.
• For leave-on AHA products, carefully control the final acid concentration and pH.
• Keep the container tightly closed and store according to the supplier’s recommended storage conditions.
• Perform compatibility and stability testing in finished formulations.
