Science
Mechanism of Action
As a precision-engineered recombinant fusion peptide, this ingredient primarily acts as a skin conditioning agent. Analogous recombinant peptides suggest it aids in maintaining skin's suppleness, improving smoothness, and refining texture by providing moisturizing benefits. Furthermore, it may form a protective film on the skin, shielding it from environmental stressors, and exhibit emollient properties that could contribute to an instant firming sensation.

Formulation
Stability
As is typical for peptides, this ingredient is expected to be water-soluble. Related proteins from Thermotoga maritima show improved stability in salt-free environments, even while maintaining solubility in high NaCl conditions. Optimal enzymatic activity for some Thermotoga maritima proteins occurs around pH 5.5-6.2, which might offer guidance for formulation pH to support peptide stability.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has not specifically evaluated R-THERMOTOGA MARITIMA POLYPEPTIDE-1 OLIGOPEPTIDE-105 OLIGOPEPTIDE-106 HEXAPEPTIDE-40. However, general CIR reports on other peptides (e.g., Tripeptide-1, Hexapeptide-12) suggest safety at typical use concentrations, generally below 10 ppm, when used as skin conditioning agents. For a structurally similar recombinant peptide, a patch test is recommended prior to use, indicating a cautious approach may be prudent.
