Hidden Precursors in Cosmetics and Household Chemicals. How Acetone, Toluene, and MEK Fall Under Tables II and III
The boundary between the free circulation of a chemical product and state control is measured by the percentage of concentration in its composition, not by the substance name on the label. A nail polish remover with an acetone concentration of 58% is sold in any store without restrictions. The exact same product with an acetone concentration of 61% formally falls under the control regime established for narcotic drugs and psychotropic substances.
Procurement departments check product compositions by looking for familiar words: acetone, toluene, acid. The legal status of a substance is set by a specific concentration figure in the safety data sheet. The ingredient list alone decides nothing. A mistake of one percent turns a standard batch of household chemicals into an object of strict reporting to the Ministry of Internal Affairs, and turns the company executive who overlooked that figure into a defendant under the Code of Administrative Offences.
Why Percentage Matters More Than the Substance Name
The Federal Law of January 8, 1998, No. 3-FZ «On Narcotic Drugs and Psychotropic Substances» (hereinafter — Federal Law No. 3) divides controlled precursors into three tables within List IV. Table I requires special control measures and business licensing. Table II establishes general control measures without licensing. Table III allows for the exemption of some of these measures. The obligation to keep records and store the substance under control remains in place regardless.
The complete list of substances and threshold concentrations is approved by Decree of the Government of the Russian Federation of June 30, 1998, No. 681 «On Approval of the List of Narcotic Drugs, Psychotropic Substances and Their Precursors Subject to Control in the Russian Federation» (hereinafter — Decree No. 681). A substance is recognized as a precursor and an object of control only when it reaches the mass-fraction threshold specified in the list.
A common error occurs here. In research briefs and secondary reviews, diethyl ether, tetrahydrofuran, and acetonitrile are frequently placed under Table II. The original text of Decree No. 681 places all three substances in Table III, alongside acetone and toluene. A one-table difference changes the size of the fine under the Code of Administrative Offences by nearly double and determines the scope of control measures applicable to the organization.
Precise Classification According to Government Decree No. 681
Below are the substances from Table III most frequently found in solvents, cleaning products, and professional cosmetics.
| Substance | Concentration Threshold | List IV Table |
|---|---|---|
| Acetone (2-propanone) | 60% or more | III |
| Toluene | 70% or more | III |
| Methyl ethyl ketone (2-butanone) | 80% or more | III |
| Sulfuric acid | 45% or more | III |
| Hydrochloric acid | 15% or more | III |
| Acetic acid | 80% or more | III |
| Potassium permanganate | 45% or more | III |
| Acetonitrile | 15% or more | III |
| Diethyl ether | 45% or more | III |
| Tetrahydrofuran | 45% or more | III |
| Acetyl chloride | 40% or more | III |
Three positions from this list are systematically misclassified.
| Substance | Erroneous Classification in Secondary Sources | Classification Under Decree No. 681 |
|---|---|---|
| Acetonitrile | Table II | Table III, 15% or more |
| Diethyl ether | Table II | Table III, 45% or more |
| Tetrahydrofuran | Table II | Table III, 45% or more |
Table II of List IV contains a different set of substances, including methyl acrylate and methyl methacrylate at concentrations of 15% or more. Both substances are used in acrylic-based nail extension systems, so they deserve close attention during composition audits of manicure and pedicure product lines.
Salts of the substances listed in Table III are subject to the same control, where the existence of such salts is chemically possible. An exception applies only to the salts of sulfuric, hydrochloric, and acetic acids. A separate rule governs mixtures containing precursors from several tables: the product is controlled under the table with the lowest sequence number among the substances found in its composition.
How Classification Affects the Fine
Article 6.16 of the Code of the Russian Federation on Administrative Offences (hereinafter — the Code of Administrative Offences) splits liability along the same three-tier logic as the list itself.
| Part of Article 6.16 | Precursor Category | Fine for Legal Entities | Additional Sanction |
|---|---|---|---|
| Part 1 | List I and Table I of List IV | ₽200,000-400,000 | Suspension of activity for up to 90 days |
| Part 2 | Table II of List IV | ₽100,000-200,000 | Suspension of activity for up to 90 days |
| Part 3 | Table III of List IV | ₽50,000-100,000 | Confiscation of the substance |
Acetone, toluene, methyl ethyl ketone (MEK), and most acids found in household chemicals and cosmetics belong to Table III. Violating the circulation rules for such goods is punished under Part 3 of Article 6.16. For products containing Table III precursors, the fine starts at ₽50,000, four times lower than the minimum under Part 1 for List I and Table I. An erroneous classification distorts the risk assessment before an inspection even happens and can inflate a compliance budget where the actual sanction is far lower.
How to Detect a Precursor in a Product’s Composition
The primary source of composition data is the supplier’s safety data sheet. Since June 1, 2022, Russia has applied GOST R 58475-2019 «Safety Data Sheet for Chemical Products. General Requirements,» which replaced the earlier GOST 30333-2007. Section 3 of the data sheet («Composition / Information on Ingredients») must state the exact percentage of each hazardous component, not a range such as «solvent content 50-70%.»
For cosmetic products, this also involves working with the International Nomenclature of Cosmetic Ingredients (INCI). Acetone in nail polish removers occurs at concentrations from 70% to 95%, which reliably places such products in the Table III precursor category. MEK is used as a solvent in nail polishes and as a denaturing additive in alcohol-containing products, although its share in finished cosmetics rarely reaches the 80% threshold.
An audit specialist has to map INCI names to the Russian-language list in Decree No. 681. Below are the most common cosmetic entries with their synonyms.
| INCI Name | Synonyms | Threshold and Table |
|---|---|---|
| Acetone | 2-Propanone, dimethyl ketone | Table III, 60% or more |
| Toluene | Methylbenzene | Table III, 70% or more |
| Methyl Ethyl Ketone | Butanone, MEK, 2-butanone | Table III, 80% or more |
| Diethyl Ether | Ethyl ether | Table III, 45% or more |
| Methyl Methacrylate | MMA | Table II, 15% or more |
If supplier data is in doubt, especially for imported products, a laboratory establishes the exact concentration by gas chromatography. The difference between 14.5% and 15.5% hydrochloric acid determines whether the organization is subject to strict accounting at all.
Grade 646 solvents, manufactured under GOST 18188, show how a formula can balance right at the edge of the limits. A typical composition includes about 50% toluene and 7% acetone. Each component individually sits below its own threshold of 70% and 60%, so this solvent does not trigger precursor accounting. Grade 647 solvent contains no acetone at all, which moves its composition even further from the threshold.
Companies with a wide product range face this task at the scale of hundreds of items. Screening safety data sheets at the procurement stage, lab verification of disputed cases, and physically segregating controlled goods in the warehouse only work as a recurring cycle, not a one-time check. A change of solvent supplier or a rebranded nail polish remover restarts this cycle for that specific item.
Storage Requirements Once a Substance Is Classified as a Precursor
Current storage rules are set by Decree of the Government of the Russian Federation of April 30, 2022, No. 809 «On the Storage of Narcotic Drugs, Psychotropic Substances and Their Precursors» (hereinafter — Decree No. 809). The rules took effect on September 1, 2022, and remain in force until September 1, 2028.
Table II and III precursors are stored in metal cabinets or safes that are locked and sealed at the end of the working day. Requirements for the engineering and technical security of storage premises are set out in a separate Decree of the Government of the Russian Federation of December 17, 2010, No. 1035. An order from the head of the organization appoints an accountable employee and sets the procedure for keeping keys and seals used when sealing storage.
Operations involving a precursor are logged in a dedicated registration journal. Entries are made from primary documents; the journal must be bound, paginated, and certified with the signature of the head of the organization and the corporate seal. Organizations must submit reports on precursor-related activity to territorial bodies of the Ministry of Internal Affairs in the manner established by law.
What to Do
Request a safety data sheet with the exact percentage. Wording such as «solvent content 50-70%» does not allow the substance’s status to be determined and should be rejected at the procurement stage.
Check every substance against Tables II and III of Decree No. 681 using the primary source. Do not rely on research briefs or secondary reviews: diethyl ether, tetrahydrofuran, and acetonitrile are routinely misclassified in them.
For mixtures with several precursors, identify the table with the lowest number. That table sets the applicable control regime for the entire product.
Organize storage in line with Decree No. 809. A metal cabinet or safe, locking and sealing after the working day, an order appointing the accountable person.
Recalculate the fine risk across the three parts of Article 6.16. For products with Table III precursors, the fine starts at ₽50,000; for Table II, at ₽100,000. Accurate classification directly shapes compliance-budget priorities.
A product’s formula changes faster than internal procurement instructions get updated. A change of solvent supplier, a switch to a new thickener, or a rebranded nail polish remover can push concentration across a threshold without a single change in the marketing materials. Re-auditing composition with every formulation change remains the only way to find out before a Ministry of Internal Affairs inspector does.
