Dodecylhexadecanol

What is Dodecylhexadecanol?

Dodecylhexadecanol is a branched, synthetic long-chain aliphatic alcohol created via Guerbet reaction from shorter-chain fatty alcohols derived from vegetable oils. It falls into the emollient and conditioning agent category for skincare products like creams and lotions. Chemically, its extended carbon chain (effectively C28 equivalent) delivers lubricity and film-forming ability. In formulations, it integrates into the oil phase, reducing interfacial tension to stabilize emulsions by hindering droplet merging and creaming. On skin, it aligns with lipid structures, promoting a silky texture and aiding moisture retention without greasiness, while supporting uniform active delivery in multi-phase products.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Emulsion stabilizer
Improves emulsion robustness by preventing droplet coalescence and phase separation, often by thickening, structuring, or strengthening the interfacial layer.
Emollient
Softens and smooths skin by filling in surface roughness and improving slip; can also help reduce moisture loss when paired with occlusives and film formers.
Skin conditioning agent
Maintains skin softness, smoothness, and flexibility.

Benefits

Delivers softening and smoothing effects for comfortable skin feel.

Strengthens emulsion integrity to maintain product consistency.

Supports skin conditioning to enhance flexibility and suppleness.
