Sorbic acid is a naturally occurring compound that's become the most commonly used food preservative in the world, and it makes the global food chain possible. 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). CAS: 110-44-1 INCI Name: Sorbic acid Benefits: - Sorbic Acid protect cosmetics and personal care products from spoilage - Effective in a wide pH range of 2.5-7. - Kosher grade Use: Typical concentration 0.05-0.3% (if used alone) or 0.05-0.15% (if used in combination with other preservatives).
