1,4-Dioxane Testing in Cosmetic Products: Safety and Quality

1,4-dioxane Test in Cosmetic Products

What is 1,4-Dioxane?

1,4-Dioxane is a by-product of the production of ethylene oxide derivatives. It can occur during the production of polyethylene glycol (PEG) compounds, SLS (sodium laureth sulfate) and other surfactants, often used in cosmetics.

Properties:

It is a volatile and colorless liquid.
It has a neutral odor.
Easily soluble in water.

Potential Effects:

Carcinogenic potential: Long-term exposure may have adverse effects on human health.
Skin and eye irritation: May cause skin and eye irritation at high concentrations.

Various tests and analyzes are carried out to ensure the safety of cosmetic products. The 1,4 dioxane test is a safety assurance method that looks for 1,4 dioxane, an impurity that can be found in trace amounts in products such as shampoos, deodorants, toothpastes and mouthwashes.

The general opinion is that the amount of 1,4 dioxane should be ≤10 ppm in cosmetic products. In fact, 1,4-dioxane is not used as an ingredient in cosmetics and personal care products, but may be formed as a by-product in the production process of some ethoxylated cosmetic ingredients such as detergents, foaming agents, emulsifying agents or solvents.

Why Should Cosmetic Products Be Analyzed for 1,4-Dioxane?

1,4-Dioxane is not an intentional component of cosmetic products but is a contaminant that can occur during production processes. Therefore, monitoring is necessary to ensure product safety and compliance with regulations.

Importance of Analysis:

Consumer Safety: Ensures that 1,4-Dioxane is not present in products at levels that could be harmful to human health.
Regulatory Compliance: 1,4-Dioxane levels in cosmetic products are limited in regions such as the European Union and the United States.
Brand Reputation: Strict implementation of quality control processes increases the credibility of brands in the eyes of consumers.

Methods to Reduce 1,4-Dioxane Levels

Manufacturers can take some measures to reduce the formation of 1,4-Dioxane:

Use raw materials that do not contain ethylene oxide.
Reducing 1,4-Dioxane levels in production processes by methods such as vacuum distillation.
Regular product testing and monitoring.
