Unveiling The Toxicological Profile Of Ingredients In Cosmetic Products

In today’s rapidly evolving personal care industry, consumer safety, ingredient transparency, and regulatory compliance have become critical pillars of product development. With increasing global scrutiny on cosmetic ingredient safety and toxicological risk assessment, manufacturers must ensure that formulations meet stringent regulatory standards while safeguarding public health.

Recent findings have raised significant concerns regarding the presence of prohibited and hazardous chemicals in cosmetic products particularly in gel nail polish removers, where methylene chloride has been detected despite strict regulatory bans. This highlights the urgent need for robust toxicological evaluation, ingredient verification, and regulatory compliance strategies within the cosmetics industry.

What is Methylene Chloride?

Methylene chloride, also known as dichloromethane (DCM) or methyl bichloride, is a volatile organic compound (VOC) widely used in industrial applications.

Key Properties:

• Colorless liquid with a sweet odor 
• High volatility and rapid evaporation 
• Strong solvent properties 

Common Industrial Uses:

• Paint stripping and removers 
• Metal degreasing and cleaning 
• Adhesive and aerosol formulations 

Despite its industrial utility, methylene chloride is strictly prohibited in cosmetic formulations under 21 CFR 700.19, due to its severe toxicological risks and carcinogenic potential.

Why is Methylene Chloride Dangerous?

Exposure to methylene chloride poses significant acute and chronic health risks, making it unsuitable for use in personal care products.

Toxicological Concerns

• Carcinogenicity: Demonstrated cancer risk in animal studies 
• Neurotoxicity: Impacts central nervous system function 
• Hepatotoxicity & Nephrotoxicity: Damage to liver and kidneys 
• Respiratory Toxicity: Harmful via inhalation exposure 
• Dermal Absorption: Easily penetrates skin barrier 

Symptoms of Exposure

Due to its high volatility, inhalation exposure is particularly concerned in poorly ventilated environments, significantly increasing systemic toxicity risks.

The Alarming Discovery in Cosmetic Products

Recent safety investigations have identified the presence of methylene chloride in several gel nail polish remover products, including:

• AL'IVER Nail Polish Quick Gel Remover (2024) 
• AL’IVER Professional MAGIC REMOVER (2024) 
• AIBRIT Gel Nail Polish Remover (2024) 
• BesTby Gel Nail Polish Remover (2024) 

A critical issue identified is labeling non-compliance, where methylene chloride is either:

• Not declared on product labels 
• Listed under alternative or misleading chemical names 

This lack of transparency significantly increases consumer exposure risk and highlights gaps in cosmetic ingredient disclosure and regulatory enforcement.

Toxicological Testing and Risk Assessment Framework

To evaluate the safety of cosmetic ingredients, a comprehensive toxicological risk assessment framework is essential.

Key Toxicological Studies

Risk Assessment Components

These assessments integrate toxicological data, exposure scenarios, and regulatory thresholds to determine whether an ingredient is safe for use.

Global Regulatory Landscape for Cosmetic Safety

Regulatory authorities worldwide enforce strict controls on cosmetic ingredients:

• US FDA (21 CFR 700.19) – Prohibits methylene chloride 
• EU Cosmetics Regulation (EC) No 1223/2009 – Strict banned substances list 
• ASEAN Cosmetic Directive – Harmonized ingredient safety standards 
• IFRA Guidelines – Fragrance safety compliance 

Compliance with these frameworks ensures global market access and consumer safety assurance.

Challenges in Cosmetic Toxicology Compliance

• Hidden or undeclared hazardous ingredients 
• Complex global regulatory variations 
• Limited toxicological data for emerging chemicals 
• Increasing demand for clean beauty and non-toxic formulations 
• Need for advanced computational toxicology and in-silico modeling
