Methyl Laitone aka. Coconut Decanone Methyl Aroma Chemical
CAS# 94201-19-1

Methyl Laitone (chemical name 8-methyl-1-oxaspiro[4.5]decan-2-one or coconut decanone methyl) is a premium synthetic fragrance compound developed and patented by Givaudan. In the market, this material is typically supplied as a 10% dilution in solvents like Dipropylene Glycol (DPG) or Triethyl Citrate (TEC) for easier dosing, due to its extremely powerful odor. Functioning primarily as a base note within the gourmand and lactonic olfactory families, Methyl Laitone has become an indispensable tool in the palette of modern perfumers.

The olfactory profile of Methyl Laitone is highly multidimensional. It delivers a deeply creamy, lactonic richness characteristic of natural coconut milk, combined with tropical fruity nuances such as ripe plum, apricot, and peach. Notably, this compound also possesses coumarinic and sweet hay undertones, providing a sophisticated warmth that prevents gourmand accords from becoming overly sugary or simply smelling like food. In perfumery, Methyl Laitone is highly prized for its ability to impart a "cosmetic body", filling out and adding voluptuous volume to white floral notes like jasmine, gardenia, tuberose, and ylang-ylang. Furthermore, it is a perfect ingredient to restore the natural, creamy milkiness to synthetic sandalwood accords, which can otherwise feel dry or harsh.

In terms of performance and application, Methyl Laitone is an exceptionally potent material, typically requiring only trace amounts (from 0.01% up to a maximum of 2%) to create profound changes in a fragrance's texture and volume. This compound boasts outstanding tenacity, lasting up to 168 hours (one week) on a smelling strip, and exhibits excellent substantivity on both damp and dry fabrics. Thanks to its high chemical stability, it is widely used not only in fine fragrances but also in personal and home care products such as shampoos, shower gels, bar soaps, and fabric conditioners (though it should be noted that it is unstable in highly alkaline liquid bleach).

Finally, regarding safety and sustainability, Methyl Laitone aligns well with modern industry standards. According to the 51st Amendment of the International Fragrance Association (IFRA), this material has no use restrictions in consumer product categories. Moreover, its safety has been peer-reviewed and assessed by the Research Institute for Fragrance Materials (RIFM). It is also evaluated as an environmentally friendly ingredient, featuring over 50% renewable carbon content, being inherently biodegradable, and classified as non-hazardous to aquatic organisms. This makes Methyl Laitone an excellent choice that meets both artistic perfumery standards and green chemistry goals.
