Erythritol
Description
Erythritol (CAS 149-32-6), also known by the food additive designation E968, is a naturally derived sugar alcohol used primarily as a low-calorie sweetener and humectant.
It is utilized across food, pharmaceutical, and personal care manufacturing. It delivers sweetness at approximately 70% the intensity of sucrose while contributing negligible caloric value to the final product.
This makes it a preferred ingredient in reduced-sugar and diabetic-friendly formulations. In food and beverage production, it is used to bulk out tabletop sweetener blends and sugar-free confectionery.
In low-calorie baked goods, it helps control moisture migration and extend shelf life. Pharmaceutical manufacturers incorporate it as a tablet excipient and coating agent for solid dosage forms.
Its low hygroscopicity supports stable formulations, while in personal care, it functions as a humectant in skin creams and serums. It also serves as a reactive polyol in specialty resin applications.
The material is supplied as a white crystalline powder or in granular form suited to direct compression. Standard grades include food-grade and FCC-compliant specifications for global distribution.
Pharmaceutical-grade material is available to USP and Ph. Eur. standards to meet strict regulatory requirements. Bulk supply is typically offered in 25 kg bags or large-format sacks.
