Menthone Glycerin Acetal

Menthone Glycerin Acetal

A specialty cooling agent that provides a smooth, refreshing, and long-lasting cooling sensation with minimal mint odor.

INCI Name: Menthone Glycerin Acetal

CAS Number: 63187-91-7

Appearance: Clear, colorless to light yellow viscous liquid

Solubility: Soluble in alcohols, glycols, and oils; limited water solubility

Function: Cooling agent, sensory modifier, refreshing agent

Menthone Glycerin Acetal is a high-performance sensory ingredient used to create a controlled cooling effect in cosmetic and personal care formulations. Unlike traditional menthol, which provides an immediate and strongly mint-associated cooling sensation, Menthone Glycerin Acetal delivers a smoother, more gradual cooling profile with significantly less characteristic mint odor. This allows formulators to introduce a refreshing sensory effect without substantially altering the fragrance profile or overall character of the finished product.

Its persistent cooling effect makes it particularly useful in scalp care, facial skincare, body care, shaving products, deodorants, cleansing systems, and other formulations where a clean, fresh after-feel is desired. Its compatibility with oil, glycol, and alcohol-based systems also provides flexibility across a wide range of cosmetic formats, including emulsions, serums, gels, and anhydrous products.

Supplied as a cosmetic raw material for formulation use.

What It Does

Menthone Glycerin Acetal provides a refreshing cooling sensation that develops more gradually than conventional menthol and remains perceptible after application. Its low characteristic odor makes it especially useful in formulations where a cooling effect is desired without introducing a dominant mint note or interfering with the intended fragrance profile.

It can be used to enhance the sensory character of skincare, scalp care, haircare, body care, and grooming products, particularly where freshness and a sustained cooling after-feel are important to the finished formulation.

Key Benefits

• Provides a smooth and long-lasting cooling sensation.
• Lower characteristic mint odor than traditional menthol.
• Supports fragrance-sensitive and non-mint formulations.
• Suitable for both skin care and hair care products.
• Useful in products designed to provide freshness and a cooling after-feel.
• Compatible with alcohol, glycol, and oil-based formulation systems.
• Can be incorporated into emulsions, gels, serums, and anhydrous products.

Typical Use Levels

• 0.05–0.20% — Light, subtle cooling effect
• 0.20–0.50% — Moderate cooling effect
• 0.50–1.00% — Stronger, more pronounced cooling effect
• Up to 2% — Specialized formulations requiring a more intensive sensory profile

How to Incorporate

• Add directly to the oil phase or a suitable solvent phase.
• May be pre-dissolved in alcohol, propylene glycol, suitable glycols, or cosmetic oils before incorporation.
• For emulsified systems, addition during the cool-down phase is generally preferred.
• For predominantly aqueous systems, pre-solubilization is recommended before addition.
• Evaluate the final cooling intensity after the formulation has fully equilibrated.

Formulation Notes

• Cooling intensity depends on concentration, product format, application area, and the surrounding formulation.
• Particularly useful when a cooling effect is required without a strong menthol odor.
• May be combined with other cosmetic cooling agents to modify onset, intensity, and duration.
• Suitable for formulations where a gradual and persistent cooling sensation is preferred over a sharp initial effect.
• Solubilization should be evaluated carefully in high-water formulations due to limited direct water solubility.
• Bench testing is recommended to determine the ideal concentration for the intended application.
