Tetradecyl Aminobutyroylvalylaminobutyric Urea Trifluoroacetate

Tetradecyl Aminobutyroylvalylaminobutyric Urea Trifluoroacetate is a synthetic peptide-based ingredient formulated as a skin conditioning agent. It combines a long-chain fatty compound (tetradecyl) with amino acid-derived peptide sequences, creating a molecule intended to improve skin texture and moisture retention.This ingredient works primarily as a humectant and emollient, helping to draw moisture into the skin whilst forming a protective layer on the surface. It appears in a small proportion of skincare formulations, typically at very modest concentrations.

The ingredient functions through two complementary mechanisms. The peptide portion mimics natural skin amino acids, signalling hydration benefits and supporting the skin's own conditioning processes. The long-chain fatty component creates an occlusive layer that prevents transepidermal water loss, helping moisture remain in the skin.Together, these actions aim to improve skin hydration, elasticity and overall comfort without a heavy or occlusive feel.

This ingredient is typically found in moisturisers, serums and hydrating treatments at very low concentrations, so no special application technique is needed. Use as directed by the product instructions. Results are most noticeable with consistent, daily use over several weeks.

This ingredient is generally considered safe for topical use in skincare formulations. As with any new skincare product, patch testing is advisable if you have sensitive or reactive skin.
