Core Components: The Sweetener and the Fillers
While consumers primarily associate Splenda with the sweet taste, its composition is more complex than just its sweetening agent. The original Splenda packet is a finely tuned mixture designed to mimic sugar's properties in a tiny, zero-calorie package. The key sweetening component is sucralose, an intensely powerful artificial sweetener. Because sucralose is approximately 600 times sweeter than sugar, it would be difficult to measure and use on its own. To make it user-friendly, the sucralose is blended with bulking agents: dextrose and maltodextrin.
Sucralose: The Sweetness Behind the Name
Sucralose is a synthetic compound derived from sucrose (table sugar) through a multi-step chemical process. This process selectively replaces three hydroxyl groups on the sucrose molecule with three chlorine atoms, creating a substance that the body does not recognize as a carbohydrate. Because it is poorly absorbed, most sucralose passes through the body without providing calories. The compound is known for its clean, sugar-like taste and stability, making it suitable for both hot and cold beverages as well as baking. The small amount of sucralose used in each packet provides the intense sweetness that Splenda is known for.
Bulking Agents: Dextrose and Maltodextrin
Dextrose and maltodextrin are common food additives used as fillers in the original Splenda packets. Both are carbohydrates derived from corn and are used for their texture and volume.
- Maltodextrin: This is a white, flavorless powder created from starch through hydrolysis. It adds texture and volume and helps preserve the product. While it contributes to the carbohydrate count, the amount in each serving is so small that it is legally labeled as "zero-calorie" in the United States.
- Dextrose: A simple sugar (glucose), dextrose provides volume and ensures that the tiny amount of sucralose can be evenly distributed. It is also derived from starches, most often corn. Like maltodextrin, the quantity in a single packet is negligible in terms of calories.
Both dextrose and maltodextrin have a high glycemic index, meaning they can cause a rapid increase in blood sugar if consumed in large quantities. However, the minimal amount present in a single serving of Splenda packets has a very small, if any, impact on blood glucose levels.
Variations in Splenda Products
It is important to note that the ingredients of Splenda can vary significantly between different product lines. The original yellow packets are just one of many options available under the Splenda brand. The company also offers products containing natural sweeteners.
Comparison Table: Splenda Products

Other Splenda Product Ingredients
The table above showcases the differences in key product types. The ingredient profile is not consistent across the entire product line. For example, Splenda's liquid sweetener drops contain water, sucralose, and preservatives like sodium benzoate and potassium sorbate, but no bulking agents. Other variants, such as those with fiber, might include soluble corn fiber. This highlights the need for consumers to check the ingredient list for specific products, as the core formula of the original yellow packets does not apply universally to all Splenda-branded items.
Safety and Controversy
The safety of sucralose has been extensively studied and debated over the years. Regulatory bodies like the U.S. Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA) have reviewed numerous studies and concluded that sucralose is safe for consumption within recommended daily limits. However, some controversies and conflicting studies have emerged, particularly concerning the effects of sucralose on gut health and its stability at high temperatures. Despite these ongoing discussions, the overwhelming scientific consensus from major health organizations supports its use as a safe low-calorie sweetener.
Conclusion
While many people refer to Splenda as simply "sucralose," its composition is more complex. The yellow-packet version, which is the most recognizable, consists of a very small amount of sucralose blended with corn-derived bulking agents, dextrose and maltodextrin. These fillers provide necessary volume and texture, allowing the intense sweetness of sucralose to be measured and used conveniently. For different applications, such as liquid drops or natural blends, Splenda uses different ingredient combinations. Consumers should be aware of these variations and always check the label for the specific product they are using. The ingredients included in Splenda packets are generally considered safe by major health organizations and are not associated with any significant health risks for the general population when consumed in moderation.
