TETRAHYDROFURFURYL ALCOHOL.

Avoid CAS 97-99-4 / FRAGRANCE, SOLVENT

Tetrahydrofurfuryl Alcohol functions primarily as a versatile solvent, facilitating the dissolution and optimal dispersion of other key ingredients within formulations. It also acts as an absorption enhancer, promoting deeper penetration of substances into the skin to maximize their efficacy.

Summary

Solvent Absorption Enhancer

Science

Mechanism of Action

On the skin, Tetrahydrofurfuryl Alcohol operates by enhancing the delivery of other compounds. Its solvent properties allow for better solubilization of active ingredients, while its penetration-enhancing capabilities assist in their absorption through the epidermal layers, thereby improving overall product performance.

Stability

This ingredient exhibits stability under typical conditions but is hygroscopic, meaning it attracts and holds water molecules. Its optimal pH range for stability and performance is between 5 and 6. As an alcohol, it may react adversely with strong alkaline or acidic components.

Caution
Sensitization risk Low

The European Union (ECHA) and company REACH registrations indicate this substance may damage the unborn child and is suspected of damaging fertility, representing significant reproductive safety concerns. It has also been identified as a serious eye irritant. Moderate irritation to skin and eyes is possible, particularly with repeated or prolonged exposure, and individuals with sensitive skin may experience dermatitis. Dermal tests on guinea pigs showed minor irritation and no sensitization. Formulations containing ≥10% Tetrahydrofurfuryl Alcohol are considered a low eye hazard if appropriate protection is used in handling. Despite being considered a 'green' solvent in industrial contexts, its application in precision skincare requires careful consideration due to these identified risks.

Our Assessment

Verdict

Avoid

Despite its utility as a solvent and absorption enhancer, the serious reproductive toxicity warnings from European regulatory bodies make Tetrahydrofurfuryl Alcohol unsuitable for Moumoujus formulations.
