The 'Chemicals' Controversy
The perception that LaCroix contains harmful chemicals stems primarily from a 2018 class-action lawsuit filed against its parent company, National Beverage Corp. The suit alleged that certain flavors contained synthetic compounds, including limonene, linalool propionate, and linalool. What amplified public anxiety was the plaintiff's assertion that linalool is an ingredient in cockroach insecticide. The implication was that a popular beverage contained a toxic, man-made substance. However, this interpretation was both misleading and out of context.
The lawsuit was ultimately dismissed in 2020 after the plaintiff withdrew their allegations and retracted the claims. Crucially, the plaintiff could not provide solid evidence that the flavorings were synthetically derived rather than natural, the core point of their argument. Independent lab testing commissioned by the plaintiff could not determine the source of the ingredients, and the plaintiff later acknowledged that these same ingredients can be derived naturally.
What Are 'Natural Essences' in LaCroix?
To understand the chemical composition, it's necessary to understand the term 'natural essence.' LaCroix derives its flavors from "natural essence oils" extracted from fruits. The process involves heating the rinds, skins, and remnants of fruits to create vapor. This vapor is then condensed to capture the concentrated oils, or essences, that provide flavor and aroma without adding sugars or calories. This is a standard and regulated process in the food industry.
Understanding the Specific Compounds
Let's break down the ingredients mentioned in the lawsuit to separate fact from fear-mongering:
- Limonene: A naturally occurring chemical found in the peels of citrus fruits like lemons, limes, and oranges. It provides a citrus aroma and is used in a wide array of products, from foods and beverages to cosmetics and cleaning supplies.
- Linalool: A naturally occurring compound found in hundreds of plants, including basil, mint, cinnamon, and lavender. While it is a component of some pesticides, this does not mean it is harmful in trace amounts in a beverage. As one food safety expert explained, stating that LaCroix is toxic because it contains linalool is akin to claiming orange juice is dangerous because it contains citric acid, which is also used in cleaning products.
- Linalool Propionate (Linalyl Propionate): A naturally occurring ester found in ginger and oils from lavender and sage. It contributes a light, floral, and herbaceous aroma. It can be derived naturally or synthesized, but the lawsuit failed to prove a synthetic origin.
In food science, the origin of a chemical—whether from a plant or a lab—does not inherently determine its safety. The key factors are purity, concentration, and intended use, all of which are subject to rigorous safety regulations by bodies like the FDA. The small amounts of these volatile organic compounds used for flavoring are far below any level that would cause harm.
Potential Health Considerations
While the 'chemical' controversy is unfounded, there are other, more science-based health aspects to consider regarding sparkling water. These are generally minor and apply to all carbonated drinks, not just LaCroix.
- Dental Health: The carbonation process creates carbonic acid, which can be mildly erosive to tooth enamel over time, especially with frequent, excessive consumption. This is a concern for all carbonated beverages, but flavored sparkling waters with their slightly lower pH can be more acidic than plain sparkling water. Moderation is key, and simple steps like drinking with a meal or through a straw can mitigate risk.
- Digestive Comfort: The carbonation can cause bloating, gas, or indigestion for some individuals, particularly those with sensitive digestive systems. This is a personal tolerance issue rather than a sign of inherent danger.
Conclusion: Navigating the Facts
The short answer to "Does LaCroix have chemicals in it?" is yes, but not in the way the misleading lawsuit suggested. LaCroix, like all food products, is composed of chemical compounds. Its flavorings are derived from natural fruit essences, which consist of naturally occurring chemical components like limonene and linalool. The lawsuit alleging synthetic ingredients was withdrawn due to lack of evidence, and the scientific consensus affirms that these ingredients are safe for consumption in the trace amounts used.
Choosing sparkling water as an alternative to sugary sodas remains a healthier option for most people. Consumers should focus on proven health factors like dental enamel erosion from carbonation rather than baseless fears about naturally occurring flavor compounds. The ultimate takeaway is that the 'chemicals' in LaCroix are simply the essential oils that give fruit its signature taste.

LaCroix vs. Generic Sparkling Water
| Feature | LaCroix | Generic Store Brand Sparkling Water | Conclusion |
|---|---|---|---|
| Flavoring Source | "Natural essence oils" from fruit. | Varies greatly; could be natural or synthetic flavorings. | LaCroix provides a specific, company-defined natural source. |
| Ingredients | Carbonated water, natural flavor. | Carbonated water, flavoring (may be natural or artificial), sometimes added minerals. | Transparency on flavor origin may differ. |
| Sodium | 0 mg sodium. | Can vary; some brands add small amounts of sodium. | LaCroix is consistently sodium-free. |
| Additives | 0 sweeteners, 0 calories. | Can have added sweeteners or calories in some cases. | LaCroix is free of added sweeteners. |
| Cost | Typically priced higher than generic options. | Often more budget-friendly. | You pay a premium for the brand and its specific 'natural' process. |
Common Natural Flavors and Their Sources
- Limonene: Found in the rinds and peels of citrus fruits like oranges and lemons.
- Linalool: A naturally occurring compound in herbs, spices, and flowers such as mint, cinnamon, and lavender.
- Linalool Propionate: An ester present in essential oils from plants like ginger and sage.
- Ethyl Butanoate: A chemical compound found naturally in fruits like pineapple, which can also be produced synthetically.
Choosing Flavored Sparkling Water
- Read the Label: If 'natural flavors' is ambiguous, look for brands that specify the source or process. LaCroix uses "naturally essenced" oils from fruit.
- Consider Dental Health: Enjoy sparkling water in moderation and rinse with plain water afterward to minimize potential enamel erosion.
- Taste Test: Experiment with different brands to find the flavor profile you prefer. Some prefer the subtle taste of natural essences over more intense artificial flavors.
The Final Verdict
LaCroix does not contain synthetic or harmful 'chemicals' as sensationally alleged in a now-retracted lawsuit. Its flavors are derived from naturally extracted fruit essences, a process that is safe and regulated. The controversy was a powerful reminder of how easily public fear can be stoked by misrepresenting scientific terminology. For most consumers, LaCroix is a safe and hydrating beverage option, provided it is consumed in moderation like any other acidic, carbonated drink.
