Some disposable e-liquids may contain additional ingredients intended to enhance flavor, vapor production, or shelf life. These can include sweeteners, stabilizers, or cooling agents such as menthol or eucalyptus. Sweeteners, like sucralose, are added to intensify flavor without affecting safety significantly.
Cooling agents can create a refreshing sensation, often used in mint or menthol flavors. While these additives are generally safe at regulated concentrations, consumers should be cautious and select products from reputable brands to avoid potential risks associated with inferior formulations.
