An artificial sweetener found in some foods, flavored lubricants, and cosmetics. Sucralose is much sweeter than natural sugar, and it stores easily. It is a calorie-free sweetener, as it does not break down in the digestive tract.

Compared to other sweeteners, sucralose is well-tolerated, and side effects are rare. It is thought to be safe for vaginal use. There is no evidence to suggest that sucralose has any effect on carcinogenic activity.
