What is Squalane?

Squalane is a saturated, branched-chain hydrocarbon lipid produced by hydrogenating squalene, a natural precursor found in olive oil, sugarcane, amaranth seeds, and human sebum. Primarily sourced from plants through sustainable processes, it serves as a versatile ingredient in moisturizers, serums, creams, lip products, and hair care formulations. In cosmetics, it acts as a non-polar emollient that spreads easily across the skin or hair surface, forming a lightweight, breathable film. This helps restore lipid balance disrupted by cleansing, enhances product texture for better slip, and supports the skin's barrier by reducing transepidermal water loss. Its stability prevents oxidation, making it ideal for oil-free or sensitive formulas where traditional oils might feel heavy.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Hair conditioning
Improves softness, shine, and manageability by reducing friction and static; commonly achieved with cationic agents, silicones, oils, or conditioning polymers.
Skin conditioning agent
Maintains skin softness, smoothness, and flexibility.
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.
Refatting
Replenishes lipids removed during cleansing to improve mildness and reduce tightness, leaving skin or hair feeling less stripped after rinse-off use.

Benefits

- Softens skin and hair by smoothing surface roughness and reducing friction.

- Conditions skin to maintain flexibility and suppleness.

- Refats after cleansing to counteract dryness and tightness.
