Common Name(s): Perfluoroisohexane

DESCRIPTION

What It Does: Provides ultra-lightweight fluorocarbon-based spreading and oxygen-carrying properties.

Why It's Used: Used as an ultra-lightweight spreading agent and specialty solvent in fluorocarbon-based formulations.

How It Works: Perfluoroisohexane (c6f14 branched isomer) provides extreme non-polarity; dissolves more oxygen than water/organic solvents; very low surface tension; water-repellent; inert.

Typically Found In: Specialty fluorocarbon formulas,high-performance sunscreens

TECHNICAL DETAILS

Primary Category: Functional ingredient – solvent

Secondary Functions: Solvent,spreading agent,emollient

Application Areas:

Typical Concentration Range: 0.5%–10%

SOURCING & ETHICS

Vegan Status: Yes

Halal Status: Yes

Source Notes: Synthetic perfluorocarbon; fluorine-containing specialty chemical.

SKIN COMPATIBILITY

Irritancy Rating: 1/5 – very low

Comedogenicity Rating: 0/5 – non-comedogenic

Sensitivity Concerns: Inert fluorocarbon; very low skin reactivity.

Safe for Sensitive Skin: Yes

SAFETY & COMPATIBILITY

Safety Profile: Good safety profile. pfas regulatory status varies by jurisdiction — verify compliance. ewg score: varies.

Works Well With: Fluorosilicone emulsifiers,other fluorocarbon ingredients

Avoid Combining With: Verify pfas regulatory compliance — some jurisdictions restricting certain perfluorocarbons

SCIENTIFIC NOTE

Perfluorocarbon solvents are under increasing regulatory scrutiny (pfas regulations); verify current regulatory status in target markets before use; functionality can often be achieved with non-fluorinated alternatives.
