Lactic acid 80%
Our lactic acid is naturally derived from the fermentation of corn and is supplied at a concentration of 80%. It is a popular and effective alpha hydroxy acid (AHA) widely used in both soapmaking and skincare formulations.
Soapmaking
Lactic acid can be used in cold process (CP) soapmaking to:
- Lower pH slightly for a gentler bar
- Help create a harder, longer-lasting soap
- Contribute to smoother texture and better lather
Usage:
Use at 10g per 1kg of soap. Add to your lye water and mix thoroughly before blending with oils.
Skincare
Lactic acid is a milder AHA than glycolic acid and offers excellent benefits for:
- Gentle exfoliation of dead skin cells
- Improved skin texture and clarity
- Hydration, especially for dry or flaky skin
- Brightening dull, uneven complexions
It is generally well tolerated, making it suitable for more sensitive skin types than other AHAs.
Effective pH Range:
Lactic acid requires a low pH (2.0–3.5) to be effective as an exfoliant.
At pH 5.5 and above, it will no longer act as an exfoliating acid.
Suggested Use in Skincare:
Typical usage levels range from 0.5% to 12%, depending on the desired effect.
- Use lower concentrations (0.5–3%) for mild daily use or hydrating toners.
- Higher concentrations (5–10%) are common in wash-off masks or peels.
Always adjust the pH of your final product and patch test before broader use.
⚠️ Sun Sensitivity Warning:
Alpha hydroxy acids like lactic acid can increase your skin’s sensitivity to sunlight. Always use SPF protection when using AHA-containing products, particularly those left on the skin.
