Science
Mechanism of Action
Topically, sucralose directly influences the sensory experience of a cosmetic product by acting as an effective sweetening agent, particularly useful in lip products. It also serves as a masking agent, skillfully concealing any unpleasant inherent tastes or odors within the formulation. Furthermore, sucralose is classified as a skin conditioning agent, supporting the maintenance of a healthy skin appearance. While indirect effects on skin health via ingestion (e.g., gut microbiome disruption, insulin impact, AGE formation) are noted in research, these mechanisms are distinct from its topical application.

Key findings
- 01 Sucralose was included in a lip balm formulation at 0.6% and was part of a Human Repeated Insult Patch Test (HRIPT) summary, contributing to its 'safe as used' conclusion for topical application.

Stability
Sucralose demonstrates exceptional stability across a broad spectrum of conditions. However, its stability incrementally decreases with escalating temperature and pH, leading to complete degradation at 180°C across all pH levels. Notably, heating sucralose to extremely high temperatures (exceeding 350°C or 662°F), especially when in contact with metal, has been documented to potentially generate toxic compounds such as chloropropanols and polychlorinated dibenzo-p-dioxins.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that sucralose, alongside other related monosaccharides and disaccharides, is safe for use in cosmetics. The maximum concentration evaluated in a cosmetic product for which safety data was available in the CIR assessment was 0.6% in a lip balm. The U.S. Food and Drug Administration (FDA) approved sucralose as a general-purpose sweetener in 1999.
