TETRADECYLEICOSYL STEARATE.

Insufficient Data / SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT

Tetradecyleicosyl Stearate is a lipophilic fatty ester that functions as a sophisticated skin conditioning agent and emollient. It contributes to a noticeably softer and smoother skin texture, while simultaneously aiding in the reduction of transepidermal water loss. Furthermore, it improves the luxurious spreadability of cosmetic formulations.

Summary

Skin Conditioning Emollient

Science

Mechanism of Action

As an emollient fatty ester, Tetradecyleicosyl Stearate conditions the skin by forming a protective, occlusive film on the surface. This action effectively minimizes moisture evaporation from the epidermis, thereby reducing transepidermal water loss (TEWL) and enhancing overall skin hydration. The resulting effect is improved skin suppleness, softness, and a refined texture, alongside optimized product feel and distribution.

Safety Profile

CIR Status
Insufficient data
Sensitization risk Unknown

The Cosmetic Ingredient Review (CIR) Expert Panel listed Tetradecyleicosyl Stearate for evaluation in a 2012 draft report on alkyl esters. However, a final safety assessment or a specific maximum concentration for this exact ingredient has not been published. While related alkyl esters, such as Octyldodecyl Stearoyl Stearate, have been deemed safe at concentrations up to 28%, comprehensive safety data specifically for Tetradecyleicosyl Stearate remains limited, leading to an 'insufficient data' CIR status.

Verdict

Insufficient Data

While Tetradecyleicosyl Stearate demonstrates potential as an emollient and skin conditioner, the current absence of specific clinical efficacy and comprehensive safety data warrants further research before a definitive recommendation can be made.
