During the manufacturing of cosmetic products, hygiene and microbiological safety must be rigorously controlled. These products, applied directly to skin, hair, or mucous membranes, can pose health risks to humans. Among the most significant risks is contamination with harmful microorganisms. Specifically, Staphylococcus aureus, recognized as one of the most dangerous bacteria in cosmetic products, is a microorganism that requires careful attention from both manufacturers and consumers.
What is the ISO 22718 standard?
ISO 22718 is an internationally recognized microbiological test method for the detection of the bacterium Staphylococcus aureus in cosmetic products. This standard was developed to ascertain the microbiological quality of cosmetic products and to ensure consumer safety.
Why is Staphylococcus aureus dangerous?
Staphylococcus aureus is a bacterium naturally found on human skin and mucous membranes. However, if it occurs uncontrolled in cosmetic products, it can lead to
- skin irritations and infections
- severe irritation of the eyes and mucous membranes
- can lead to severe health problems in individuals with compromised immune systems
- compromise product reliability and brand reputation
For this reason, cosmetic products must undergo microbiological analysis in accordance with ISO 22718 prior to their market launch.
Analytical Procedures According to ISO 22718
- A sample is collected and inoculated onto a suitable culture medium.
- After a specified incubation period, colony formation is examined.
- Suspect colonies are confirmed using biochemical or molecular methods.
- If Staphylococcus aureus is detected, the product is classified as microbiologically unsuitable.
For which cosmetic products is this required?
- 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 conducted?
- Compliance with regulatory requirements
- Demonstration of Product Safety
- Prevention of consumer complaints and adverse health effects
- Enhancement of brand credibility
- Preparation of the necessary technical documentation for export and approval procedures
Microbiological controls are essential for safe cosmetic products
Through Staphylococcus aureus analyses conducted in accordance with ISO 22718, legal requirements are met, and consumer health is protected. Manufacturers must ensure regular microbiological controls are performed in specialized laboratories to produce safe, high-quality, and legally compliant products.
