Description: Sorbic acid (synonym: 2,4-hexadienoic acid) is a natural, straight-chained fatty acid. It is widely been used as a preservative in foods and cosmetics. For equal preservative power, only three parts of sorbic acid must be used to equal four parts of potassium sorbate. Purity >99% (FCC grade). Fine white to off-white, free-flowing powder. Barely soluble in water (about 1% at 20°C, and 4% at 90°C). Somewhat better soluble in plant oils and propylene glycol (1% at 20°C and 10% at 90°C).
