Sodium salt of lactic acid produces naturally by fermentation of sugars. Clear and viscous liquid, light smell. Emulsions: used as a co-conservative. Soaps: Used to harden the soaps faster, make them last longer and give them a more glossary finish. Soluble in water and alcohol. It is a 60% combination of sodium lactate and 40% water.

INCI : Lactate sodium

Properties : Antioxidant, bacteriostatic agent (stabilizes bacteria levels), pH control agent, humor

Uses: Creams and lotions, soaps

The effects of sodium lactate in soaps

- On pigments and other dyes: lactate can pale the shades of the pigments and micas used to color the soaps. These effects are very light and generally imperceptible.

- In the molds: the temperature increases in the molds, but no sign of degradation of fragrances or other has been observed. The lactate helps to unmold the soaps made in individual molds.

- On hardness and cutting: the soap hardens much faster with sodium lactate than without. It is therefore recommended to unmold and cut the soaps as soon as possible. Generally, soaps are ready to be cut after 18 hours unlike 24 hours or more without lactate.

- On the weight of the soaps: the soaps made with sodium lactate will lose less water than a soap made without lactate and will shrink less.

- to the touch and other effects: sodium lactate gives soap a silky effect and a soft touch in addition to giving it moisturizing properties. Note that no effect on the quantity or quality of the foam has been observed. The sodium lactate does not affect the pH of the soap either.

- Trace: Please note, because the sodium lactate quickly gives a thick paste. It is recommended for opaque soaps that do not need to be worked. It is not recommended for marbing techniques that require a more liquid paste.

Use : Should be added to the aqueous phase with heat to ensure appropriate incorporation.

Concentration: from 1 to 3%

In solid soaps: the recommended rate of sodium lactate to be used is 25 g per kilo of oil used in the formulation. Here's how to determine the quantity:

25 g of sodium lactate per kg of oil

The sodium lactate is at a concentration of 60% therefore, to obtain 25 g of lactate it is necessary to divide 25 g per 0.60, which gives approximately 42 g of sodium lactate at 60%. Your quantity of oil in kg x 42 = quantity of lactate in grams.

Ex.: 5 kg of oil x 42 = 210 g of sodium lactate

Water reduction

Since sodium lactate contains 40% water, the amount of water must be reduced in the same proportion. If you used 210 g of lactate, then there are 210 g x 0.40 = 84 g of water. It will be necessary to subtract 84 g of water from the amount of total water calculated for your recipe.

Important: Add the sodium lactate to water before hydroxide.

Mon savon n'a pas durci

Il y a une erreure dans mon texte précédent. Le lactate est resté dans l'eau longtemps avant d'incorporer le NAOH.

Mon savon n'a pas durci

J'ai suivi vos calculs pour incorporer le lactate de sodium pour la première fois dans mon savon. J'ai mélanger le lactate à l'eau avant le NAOH (comme recommandé), mais il est resté dans l'eau quelque temps avant que j'y ajoute le lactate. Est ce que ça peu avoir changé quelque chose? Est-ce qu'il fallait mélanger le NAOH rapidement pour lui donner sa chaleur?

Étant donné que le lactate de sodium contient 40% d’eau, il faut réduire la quantité d’eau utilisée dans la même proportion. Si vous avez utilisé 210 g de lactate alors il y a 210 g X 0,40 = 84 g d’eau. Il faudra soustraire 84 g d’eau à la quantité d’eau totale calculée pour votre recette.


Bonjour, pouvons nous utiliser le lactate de sodium dans les shampoings en barre merci

Oui ce produit ajustera le Ph.


Bonjour. Est ce que l'ajout d'acide lactique dans une fabrication de savon fait baisser le ph du savon ?

Il baisera le PH de votre savon et l'aidera à durcir plus vite aussi
