The biggest hurdle for the Canadian perfume hacker is compliance, regulations and the Law. SDA 40B requires complex permits and documentation to purchase legally. This is no legal advice, but you might want to have a little look at the actual law: Prohibition — use of SDA 96 No person shall, except in accordance with a specially denatured alcohol registration issued to the person, use specially denatured alcohol. Prohibition — possession of SDA 97 No person shall possess specially denatured alcohol. Prohibition — supply of SDA 98 No person shall give possession of specially denatured alcohol to a person who is not a spirits licensee, an SDA registrant or an alcohol registrant. Prohibition — sale of SDA 99 No person shall sell specially denatured alcohol. I don't know about you but there's very little room for interpretation, here and "everybody's doing it" is no excuse. Luckily for you, we’ve cleared the path for safe and legal perfume making in more ways than one so you can worry about the actual scent. Because of our specific formulation, the new Contrebande Neutral perfumery base can be sold freely to Canadian customers. You get the professional-grade performance of a lab-standard solvent without the administrative headache of government permits. For the DIY perfume maker and the perfume hacker, the difference between a masterpiece and a muddy mess lies in the solvency, stability, and purity of your carrier. Most hobbyists are forced to choose between industrial-grade chemicals they can’t easily source and low-quality "perfumer’s alcohols" that lack the structural integrity to hold complex accords. Why This Base is Superior to Standard SDA 40B 1. Canadian SDAG-3 Advantage While most commercial bases rely on SDA-40B, we have engineered our formula around 90% of SDAG-3 Azeotropic Grain Alcohol (CAS: 64-17-5). Sourced from premium Canadian grain, SDAG-3 provides a cleaner, more consistent structural profile. By moving away from the usual SDA-40B, we offer a base that behaves more predictably during the maceration process, as it's completely devoid of poisonous tert-Butyl alcohol. This is one less reagent you have to worry about degrading your other ingredients, ensuring your top notes remain vibrant and your base notes stay anchored. 2. Pre-Engineered for maximum solvency and stability Why waste time and money on complex chemistry? We’ve done the heavy lifting for you. Our neutral base is pre-formulated with a precision-balanced additive package designed to maximize your creative freedom: 5% low-odor dipropylene glycol (CAS: 25265-71-8): Increases the "fixative" power of your blend, allowing scents to linger longer on the skin without introducing unwanted notes. 5% Isopropyl myristate (CAS: 110-27-0): A powerhouse solvent that ensures even the most stubborn, resinous, and heavy molecules remain perfectly in solution: no cloudiness, no precipitation. 0.1% Butylated hydroxytoluene (CAS: 28-37-0): The gold standard in antioxidant protection. It prevents the oxidation of your precious essential oils and aroma chemicals, preserving the integrity of your work over months and years.
