Question

Regarding the product `Sodium Lactate (60% Liquid, Natural)`, how should it be mixed with water, and how much water should be added to 50 grams of this product for use in a cosmetic formula?

Answer

How to Mix Sodium Lactate with Water

Based on the product information for Sodium Lactate (60% Liquid, Natural), this ingredient is typically supplied as a liquid solution that is 60% Sodium Lactate and 40% water. This means the 50 grams you have already contains both Sodium Lactate and water.

The amount of additional water you need to add depends entirely on the specific cosmetic formula you are creating and the desired final concentration of Sodium Lactate in that formula. Sodium Lactate is commonly used at a concentration of 2-10% in finished products.

To determine how much water to add, you first need to decide:

  1. The total weight of your final product (e.g., 100 grams, 200 grams).
  2. The desired percentage of Sodium Lactate in your final product (e.g., 3%, 5%).

Once you have these values, you can calculate the amount of the 60% Sodium Lactate solution needed and the remaining amount of water and other ingredients.

For example, if you want to make 100 grams of a cream with 5% Sodium Lactate:

  • You need 5 grams of pure Sodium Lactate in the final product.
  • Since your product is a 60% solution, you would need (5 grams / 0.60) = 8.33 grams of the Sodium Lactate (60% Liquid, Natural) solution.
  • The remaining amount (100 grams - 8.33 grams - weight of other ingredients) would be water and other components of your formula.

Therefore, there is no single answer for how much water to add to 50 grams of Sodium Lactate without knowing your target formula and desired concentration. Always refer to recommended usage rates for your specific application.

Update 2026-05-24

The main answer is still valid: Sodium Lactate (60% Liquid, Natural) is already a water-soluble liquid containing about 60% sodium lactate and about 40% water, so there is no single fixed amount of water to add to 50 g unless the final batch size or desired sodium lactate level is known.

Important calculation clarification: 5% pure sodium lactate active and 5% of the 60% liquid product are not the same.

  • 50 g of Sodium Lactate (60% Liquid, Natural) contains about 30 g sodium lactate active and about 20 g water.
  • If the target is 5% pure sodium lactate active, calculate: required liquid product = required sodium lactate active ÷ 0.60. For example, a 100 g formula at 5% pure sodium lactate active uses 8.33 g of the 60% liquid, then water and other ingredients are added to complete 100 g.
  • If using 5% of the 60% liquid product in a formula, it supplies only 3% pure sodium lactate active.
  • If all 50 g of the 60% liquid is intended to give 5% pure sodium lactate active, the final batch would be 600 g total, so the remaining 550 g would be water and/or other ingredients.

Current catalog guidance: add Sodium Lactate (60% Liquid, Natural) into the water phase and mix until uniform. Typical use remains 2-10%, commonly 3-5%, and the final formula should be around pH 3.5-10. At levels above 3%, use appropriate caution because the product information notes possible acceleration of skin cell turnover; daytime products should include suitable sun-exposure precautions. Sodium Lactate Plus is a different ingredient blend containing sodium lactate plus sodium gluconate and should be calculated according to its own usage range.
