In the production of cosmetic products, hygiene and microbiological safety must be controlled. Because these products, which are applied directly to the skin, hair or mucous membranes, can pose health risks to humans. The greatest risks include contamination with harmful microorganisms. In particular, Staphylococcus aureus, one of the most dangerous bacteria in cosmetic products, is a microorganism that manufacturers and consumers must pay attention to.
What is the ISO 22718 standard?
ISO 22718 is an internationally valid microbiological test method for detecting the bacterium Staphylococcus aureus in cosmetic products. This standard was developed to determine the microbiological quality of cosmetic products and to ensure the safety of consumers.
Why is Staphylococcus aureus dangerous?
Staphylococcus aureus is a bacterium that naturally occurs on the skin and mucous membranes of humans. However, if it occurs uncontrolled in cosmetic products, it can
- lead to skin irritation and infections
- lead to severe irritation of the eyes and mucous membranes
- lead to serious health problems in people with weakened immune systems
- impair the reliability of the products and the reputation of the brand
For this reason, cosmetic products must be subjected to a microbiological analysis according to the ISO 22718 standard before they are launched on the market.
Analysis methods according to ISO 22718
- A sample is taken and applied to a suitable nutrient medium.
- After a certain incubation time, the colony formation is examined.
- Suspect colonies are confirmed with biochemical or molecular methods.
- If Staphylococcus aureus is detected, the product is classified as microbiologically unsuitable.
For which cosmetic products is this prescribed?
- Skin care products (creams, lotions, serums)
- Hair care products
- Cosmetic products for babies
- Make-up products
- Products for the eye area and lips
- All other cosmetics that come into contact with the skin
Why should microbiological tests be carried out?
- Fulfillment of legal requirements
- Proof of product safety
- Avoidance of consumer complaints and negative effects on health
- Increase in brand credibility
- Creation of the necessary technical documentation for export and approval procedures
Microbiological controls are essential for safe cosmetic products
With the Staphylococcus aureus analyses carried out according to the ISO 22718 standard, the legal requirements are met and the health of consumers is protected. Manufacturers must have regular microbiological controls carried out in specialized laboratories to produce safe, high-quality and legally compliant products.
