Product Overview
MCK contributes a warm, dry foundation to woody, amber and fougere fragrances. The cedar character gives the composition a defined woody direction, while the softer musk facets complement the base. Leathery and vetiver-like nuances make it relevant to fragrances built around dry woods and leather.
In floral compositions, MCK adds a woody background beneath the floral accord. It also blends with mossy and creamy fragrance directions. This makes it useful both in fragrances with a prominent woody theme and in compositions where wood provides supporting structure.
Its persistence is particularly relevant to the later development of a perfume. It is used within fragrance concentrates for commercial fine fragrance, personal care and household products.

Applications of Methyl Cedryl Ketone
Fine Fragrance Concentrates
MCK is used in cedar, leather, amber and fougere perfume compositions. It brings dry woody character to the fragrance base and complements musky notes. In floral perfumes, it provides a woody contrast beneath the floral accord.
Within a woody perfume, the cedar and leathery facets contribute to the main scent direction. In a floral or musky composition, the same material can provide a supporting woody background. These blending roles make it relevant to both wood-led perfumes and softer compositions with a dry base.
Soap Fragrances
In soap fragrances, MCK contributes woody and musky character to cedar, amber and floral-woody themes. It is incorporated as part of the fragrance compound blended into the soap base.
The relevant product conditions include the alkaline soap base and processing temperature. MCK adds a dry wood facet within the fragrance compound; odor balance and color in the finished bar remain specific to the formula. Its liquid color is particularly relevant in white or lightly colored soaps.
Shampoo and Personal Care Fragrances
MCK is used in fragrance compositions for shampoo and other perfumed personal care products. It adds a dry woody background to floral, amber and musky scent directions.
In liquid hair-care products, the fragrance is incorporated into a surfactant or emulsified base. Fragrance solubilization, product clarity and the odor of the finished formula affect its use. Its woody note forms part of the product fragrance, alongside the floral, amber or musky elements of the blend.
Detergent and Fabric Care Fragrances
Laundry detergents and fabric conditioners are established application areas for woody fragrance ingredients of this type. MCK contributes a warm woody-musky foundation to the fragrance compound, alongside the other ingredients that create the intended clean or floral character.
Liquid detergent, powder detergent and fabric conditioner bases have different formulation conditions. Odor balance, appearance and fragrance stability therefore depend on the product base. The same fragrance can behave differently in liquid detergent, powder detergent and fabric conditioner.
Candle Fragrance Compositions
MCK can be used in candle fragrance blends built around cedar, warm woods, leather or amber. It contributes to the woody part of the composition alongside the other aroma materials.
Candle performance involves both the fragrance blend and the wax-and-wick system. The fragrance character of the unlit candle and during burning can differ. MCK is an ingredient for the overall candle fragrance, with loading and performance established for the finished candle formulation.
Solubility and Fragrance Incorporation
MCK dissolves in ethanol and is relevant to alcoholic perfume concentrates. Its water insolubility makes the fragrance carrier and incorporation system important in water-rich products.
In aqueous personal care or household bases, incorporation depends on the complete fragrance blend and its solubilizer, surfactant or emulsion system. Direct mixing with water alone does not form a clear solution.
Fragrance loading is specific to the complete composition and finished-product base.
European Cosmetic Labelling
Acetyl Cedrene is listed in Annex III, entry 327, of Regulation (EC) No 1223/2009, as amended by Regulation (EU) 2023/1545. For EU cosmetic products, individual ingredient labelling is required above 0.001% in leave-on products and 0.01% in rinse-off products.
The thresholds apply to Acetyl Cedrene in the finished cosmetic product.
