This is an automatic translation

Sodium levulinate is the sodium salt of levulinic acid and is used as a preservative and skin conditioning agent in cosmetics and personal care products. It is obtained starting from the degradation of the cellulose of cane sugar after treatment with mineral acids and subsequent neutralization with soda. It occurs in the form of a white crystalline solid, soluble in water and polar organic solvents. It is used as a broad-spectrum preservative due to its activity of contrasting the growth of aerobic and non-aerobic microorganisms. It is used to give stability and shelf life to emulsions, tensols such as shampoos and shower gels and in face serums.
