What Sucralose does
- Adds sweet taste to flavored products
- Sweetens without adding sugar bulk
- Keeps its sweetness when heated
Sucralose starts from sucrose, the sugar in table sugar. Chemists replace three of sucrose's hydroxyl groups, which are small oxygen and hydrogen groups, with chlorine atoms. That change makes the molecule taste far sweeter than sugar, yet it does not add the bulk that sugar brings to a formula.
Formulators like sucralose because it dissolves easily in water and stays sweet when heated. Only a small amount is needed, so it sweetens lip products and oral care items without changing their texture. It has no feel of its own, so the product's base decides how it feels on the skin or lips.
Good for
Best for flavored products such as lip balms, toothpaste and mouthwash, where a sweet taste is part of the appeal.
Frequently asked questions
Is sucralose the same as sugar?
No. Sucralose is made from sugar but is chemically changed, so it tastes much sweeter and is used in much smaller amounts. In beauty products it is used for taste, not for moisture.
Is sucralose safe in lip balm or toothpaste?
Sucralose is widely used in food and personal care products and is generally well tolerated. If you have a known sensitivity or a specific concern, a doctor or dermatologist can advise you.
