what is Sodium lactate?
Sodium lactate is the sodium salt of lactic acid and has a mild saline taste. It is produced by fermentation of a sugar source, such as corn or beets, and then, by neutralizing the resulting lactic acid to create a compound having the formula NaC3H5O3.
Sodium lactate, in the form of Ringer's lactate solution, is used as a medication and is included on the World Health Organization's List of Essential Medicines.
What is sodium lactate used for
Sodium lactate, a salt derived from lactic acid, is a compound with a wide range of applications across various industries, including medical, skincare, food, and industrial.
Medical Applications:
Metabolic acidosis: Sodium lactate is used intravenously to treat metabolic acidosis, a condition characterized by an excess of acid in the blood.
Arrhythmias: It can also be administered to help manage certain types of irregular heartbeats.
Skincare Benefits:
Humectant: Sodium lactate acts as a humectant, drawing moisture into the skin to improve hydration and suppleness.
Keratolytic: It also possesses keratolytic properties, helping to gently exfoliate dead skin cells and enhance skin texture.
Food Industry:
Preservative: Sodium lactate is used as a preservative in various food products to extend shelf life.
Flavor enhancer: It can also contribute to the overall flavor profile of certain foods.
Industrial Uses:
Textiles: Sodium lactate is employed in the textile industry as a plasticizer and softener for fabrics.
Plastics: It can also be used as a component in the production of certain plastics.
What Does Sodium Lactate Do In Soap?
Sodium lactate serves a dual purpose in soap making, particularly in cold process and hot process methods. When incorporated into soap recipes, it facilitates a quicker hardening process. The soap becomes more manageable during unmolding, ensuring a smoother and cleaner final product.
In hot process soaps, sodium lactate plays a crucial role in creating a smoother texture. This attribute allows artisans to experiment with intricate designs, making the soap mixture more malleable and easier to transfer into molds.
How Much Sodium Lactate in Soap?
For cold-process soap, the recommended usage is 1 teaspoon of sodium lactate per pound of oils. To ensure optimal results, add it to the cooled lye water. Be cautious not to exceed this recommended amount, as an excess of sodium lactate can lead to brittleness and crumbling in the finished product.
How Much Sodium Lactate in Hot Process Soap?
In hot process soap making, the ideal usage is 3-5% of the oil weight in the soap. Sodium lactate can be added at any stage of the process, either to the lye water or during the cooking phase. This flexibility allows artisans to tailor the soap-making experience to their preferences.
