What Is Mck Sg?
Mck Sg is an aroma chemical created by IFF that gives perfumers a reliable woody note. The molecule is officially named 1-Cedr-8-en-9-ylethanone, a bit of a mouthful, yet you can always track it down by its CAS number 32388-55-9. Although IFF owns the registered trade name, other suppliers sometimes offer equivalent material under generic labels.
Production involves controlled chemical synthesis that starts with plant-derived raw materials, letting the finished ingredient qualify as renewable, naturally sourced and suitable for vegan formulas. The process also makes use of by-products that would otherwise go to waste, so the material fits the industry’s upcycled trend.
At room temperature you will find Mck Sg as a clear liquid with a faint yellow tint. It pours easily, blends well with most perfume solvents and stays stable under normal lab conditions. When stored in a cool dark place the shelf life typically runs three to four years before any noticeable drop in quality.
Within the fragrance world Mck Sg is fairly common, especially in modern cedar-forward compositions, fine fabric conditioners and bar soaps where woody depth is needed without adding cost. It sits in the affordable bracket, allowing creators to use it generously when building long lasting cedar impressions.
Mck Sg’s Scent Description
Mck Sg belongs to the woody family. On a blotter the first impression is fresh-cut cedar planks quickly followed by a richer resin note that hints at pencil shavings and dry pine sap. As the minutes pass a gentle musky warmth surfaces, rounding off any sharp edges and bringing a smooth almost creamy undertone. There is also a faint amber sweetness that keeps the wood from smelling too raw.
The material acts as a base note. It rises slowly, supports middle accord ingredients for hours then lingers on skin and fabric long after top notes have vanished. On a test strip its presence is still clear after two days and in some blends can be perceived for nearly a week.
Projection is moderate which makes it a solid framework rather than a loud star. It helps anchor brighter notes without stealing attention and adds lasting body to compositions that risk fading too quickly.
How & Where To Use Mck Sg
Perfumers reach for Mck Sg when they want a clean cedar backbone that stays present for hours. It replaces expensive natural cedarwood oil in modern blends, offering the woody warmth without the batch-to-batch shifts found in naturals. It shines in masculine fougères, dry ambers, woody musks and even fruity florals that need a discreet wood touch underneath.
At low dosages around 0.1 % it acts mainly as a fixative, extending lighter notes like citrus or lavender. Around 0.5 % to 2 % the cedar facet becomes noticeable, smoothing sharp edges in smoky or leathery accords. Pushed closer to 5 % it dominates the formula with pencil-shaving dryness that can crowd out delicate florals, so most creators keep it under 3 % in fine fragrance and under 1 % in functional products.
Its scent shape changes with strength. In traces the resin nuance is softer and slightly creamy. Mid levels highlight the musky warmth while very high levels can feel dry and dusty. Because it is long lasting, over-use can leave a blunt plank-like note on skin or fabric that some people read as stale.
Mck Sg works well in alcohol, dipropylene glycol and most oil bases so no special solvent is needed. A 10 % ethanol or DPG solution makes smelling sessions safer and blending easier. Avoid pairing it with very citrus-heavy bases in soaps as it may mute the sparkle after cure. In powder detergents stability is only moderate so keep the level low or blend with a booster like Iso E Super to improve consumer pickup.
Before compounding larger batches, run a small pilot to watch for crystallisation with cooler warehouse temperatures though this is rare. Shake the drum well to homogenise any settled material then weigh by mass not volume for better accuracy given its higher log P.
Safely Using Mck Sg
Dilution is key so mix Mck Sg down to at most 10 % before any direct smelling. Avoid sniffing from the neat bottle since concentrated vapour can irritate nasal passages. Work in a well-ventilated space or under a fume hood and always wear gloves and safety glasses to keep splashes off skin and eyes.
Like many woody ketones it may cause mild skin irritation in sensitive users. If you notice redness wash with soap and water and stop exposure. Anyone who is pregnant or breastfeeding should speak with a doctor before handling aroma chemicals as a precaution. Brief low-level contact is usually fine yet long or repeated high-concentration contact can raise the risk of headaches or dermatitis.
Store finished dilutions in amber glass away from heat and strong light to slow oxidation. Wipe spills promptly because the material is slippery and hard floors become a hazard. Although it is classed as non-biodegradable never pour waste into drains. Collect any leftover or expired stock in a sealed container and send it to a licensed chemical disposal service.
Always read the most recent safety data sheet from your supplier and revisit it often since updates are common. Follow the current IFRA guidelines for category-specific limits to keep your formulas within safe exposure levels.
How To Store & Dispose of Mck Sg
Keep Mck Sg in tightly sealed bottles stored in a cool dark cupboard away from radiators or direct sunlight. Refrigeration is optional but can add an extra year or two of freshness if you have the space. Sudden temperature swings shorten shelf life so aim for steady conditions around 15 °C.
Polycone caps make the best closure for both the neat material and any dilutions because the cone liner forms a snug seal that limits air seepage. Skip glass dropper bottles since the rubber bulbs breathe and let oxygen creep in. Whenever possible top up partial bottles with inert gas or transfer them to smaller containers so the headspace stays minimal and oxidation slows.
Label every container clearly with “Mck Sg,” the CAS number 32388-55-9, concentration if diluted and the date it was filled. Adding hazard pictograms or phrases from the latest SDS helps anyone sharing the workspace recognize safety needs at a glance.
In the lab place bottles in secondary trays to catch drips. If a spill occurs mop it up with disposable towels then wash the area with detergent. Collect used towels in a sealed bag for professional disposal.
When the material reaches end of life do not rinse it down the sink because Mck Sg is classified as non-biodegradable. Decant leftovers into a clearly marked waste drum and arrange pickup by a licensed chemical disposal company that handles organic solvents. Rinse empty bottles with a small amount of ethanol, add the rinse to the waste drum then recycle or discard the clean containers following local rules.
Summary
Mck Sg is a renewable upcycled woody ketone from IFF that delivers a warm cedar profile with soft musk undertones. It performs as a dependable base note giving long lasting support to fine fragrance hard soaps fabric conditioners and more.
Perfumers value it for its stable cost friendly alternative to natural cedarwood oil and for its resistance to oxidation when handled correctly. The molecule carries moderate projection yet stays detectable for days which makes it a versatile fixative as well as a character note. Stability is excellent in most applications except high heat powder detergents where performance drops.
Keep an eye on dosage since very high levels can turn dry and dusty. Store it tightly capped in a cool spot or refrigerated to reduce oxidation and remember that disposal requires professional waste handling due to its non-biodegradable status.
Commercial quantities come straight from IFF or authorized distributors while hobbyists can order smaller lots from specialty aroma shops and generic suppliers that list it under the CAS number or generic cedar ketone names. Whether you are scaling a fine fragrance launch or tinkering with a weekend project Mck Sg offers an accessible route to long lasting modern cedar warmth.
