Product description

Lactic Acid 80% is a natural organic acid of plant origin, obtained by fermentation of carbohydrates (e.g. corn or sugar beet). It is one of the most commonly used AHA acids (alpha-hydroxy acids) in cosmetics, where it is used mainly for its exfoliating, moisturizing and pH-regulating properties. In the skin it is naturally formed as part of metabolism and is a component of the so-called Natural Moisturizing Factor (NMF), therefore it is very well tolerated and effective in restoring a healthy skin barrier.

Key benefits:

• Gently exfoliates dead skin cells and refines the skin surface.

• Moisturizes by binding water in the skin.

• Improves elasticity and the overall appearance of the complexion.

• Regulates the pH of cosmetic products, thereby increasing their stability.

• Supports cell renewal and stimulates the skin’s natural regeneration.

Suitable for products such as:

• facial toners and serums with AHA acids

• anti-ageing creams and emulsions

• products for skin brightening and radiance

• peeling masks and treatment courses

• shampoos and hair treatments for pH regulation

• deodorants and intimate hygiene products

Use in formulation:

• Solubility: completely soluble in water, partially in alcohol.

• Recommended dosage:

  • as an active ingredient in facial cosmetics: 1 – 10% (higher concentrations may be irritating)

  • as a pH regulator: as needed to achieve the desired pH value

• Incorporation: added to the aqueous phase during cooling, or directly at the end of the formulation to adjust pH.

• Thermal resistance: process at lower temperatures (< 40 °C) to avoid degradation of the active substance.

Lactic Acid 80% is a universal cosmetic raw material that combines exfoliating, moisturizing and pH-stabilizing effects and is therefore an indispensable component of modern skin and hair care formulations.

Safety rating of the raw material according to the EWG: 2-5 depends on the use, 2 if lactic acid is used in products with low inhalation risk (e.g. creams, serums, liquid products) and 5 if it is used in products that may be inhaled (sprays, powders), due to the risk of respiratory tract irritation.

FAQ – Frequently Asked Questions

Is lactic acid suitable for sensitive skin?
Yes, but only in very low concentrations (1 – 3%) and with correctly adjusted formulation pH. Higher concentrations may cause redness or irritation.

Can I use it as a preservative?
No, lactic acid does not have sufficient preservative effect, but it is often combined with other preservatives because it helps to maintain the optimal pH for their efficacy. 

How does lactic acid differ from glycolic acid?
Lactic acid has a higher molecular weight than glycolic acid, therefore it acts more gently and is more suitable for sensitive skin.

Is lactic acid vegan?
Yes, in cosmetics lactic acid produced by fermentation of plant raw materials is used, so it is also suitable for vegan formulations.

How to correctly dilute lactic acid?

If you want to prepare a different concentration, proceed according to the following formula:

X = (desired concentration 0.5 for 50% x amount you want to prepare in g or ml)/original concentration 0.8 for 80%

To prepare 100 g of a 50% concentration from 80% acid, the formula will be as follows:

X=(0,5x100)/0,8

X=62,5

So to obtain 100 g of a 50% solution you will need 62.5 g of 80% acid and 37.5 g of water.

To achieve an accurate result, we recommend weighing the raw materials rather than measuring by volume.
