Sodium lactate CAS 312-85-6

What is of Sodium lactate CAS 312-85-6?

Sodium lactate is the sodium salt of lactic acid, naturally produced through the fermentation of sugars like corn or beets. It is a highly versatile, biodegradable compound widely used as a food preservative, cosmetic moisturizer, soap-making additive.

Specification

Application Scenarios:

Cosmetic Grade

1. Natural Moisturizing Factor (NMF) Supplement: Sodium lactate is a core component of the natural moisturizing factor in the human skin's epidermis. Its water-absorbing and moisturizing capacity is several times that of glycerin. Widely added to high-end moisturizing lotions, creams, serums, and masks, it deeply locks in moisture, keeping skin elastic.

2. Synergistic Whitening and Anti-aging: When used in combination with lactic acid (AHA) or vitamin C, it provides a dual effect of gently exfoliating dead skin cells, promoting cell regeneration, fading melanin, and brightening skin tone.

3. Gentle Conditioner in Shampoos and Cleansers: Used in shampoos or shower gels as a pH adjuster, it effectively reduces the irritation of surfactants to the skin.

Food Grade

1. Moisture Retention and Preservation in Meat Products: Widely used in meat products such as hot dogs, ham, bacon, and roast meat. Sodium lactate effectively locks in the internal moisture of meat, significantly increasing the yield of meat products and maintaining the tenderness of the meat. More importantly, it effectively inhibits the growth of Listeria, Staphylococcus aureus, and Clostridium botulinum, directly extending the shelf life of meat products.

2. Acidity Regulator and Flavor Improver: Used as a pH regulator in candies, jellies, fruit juices, and baked goods to soften the sour taste.

3. Brewing Industry: Used in beer and spirits brewing to adjust the pH of mash or wort, inhibiting the growth of unwanted microorganisms.

Industrial Grade

1. Plastics Industry (PLA Precursor and Modification): Used in the research and development of intermediates for the synthesis of biodegradable plastics—polylactic acid (PLA), or as an environmentally friendly plasticizer and emulsifier in the processing of specific resins.

2. Dyeing and Leather Industry: Used as a buffer salt for pickling and neutralization in leather processing, helping the leather absorb dyes and tanning auxiliaries more smoothly.

3. Special Lubricating Oil Blending: Used as a hygroscopic additive in certain water-based lubricants or metal cutting fluids to prevent excessive drying or cracking of equipment surfaces.
