Cosmetic Testing / Health, Beauty, Personal Care Products Testing Labs
Microbiological Testing of Health, Beauty, Personal Care, Cosmetic Products
Microorganisms in cosmetics may cause spoilage or chemical change in the product and can possibly harm cosmetic, health, beauty, and personal care product consumers. Cosmetics do not need to be sterile, but their preservative system must be able to take care of harmful microbial contamination.
For the manufacturer of cosmetic and personal care products, it is important to ensure that their products are free of pathogenic (harmful) microorganisms and are safe for consumer use.
When consumers use cosmetics products and health, beauty, or personal care products, they are repeatedly challenging the cosmetics or toiletry products (for example: mascara, eye shadows, face powder, foundations, lotions, face creams, shampoos, conditioners, etc.) by contaminating ("challenging") them with their unclean hands.
Health, Beauty, Personal Care, and Cosmetic Product Testing Methods
Cosmetics and personal care products are tested to assure that the products are safe and ready to be released to the consumer market. Products are tested by the following methods:
- Aerobic Plate Count (APC)
This test determines the total number of aerobic bacteria per ml or gram of the personal care or cosmetic product. This test gives you total count of bacteria present.
It is a 48 to 72 hour test. This is a routine test, ordered on each lot manufactured of healthy, beauty, cosmetic, and personal care products.
- Yeast and Mold Count
This test determines the total number of yeast and fungi per ml or gram of the personal care or cosmetic product. It is carried out for five days.
*It is ordered along with the APC test (aerobic plate count).
- Enrichment Method for Specific Pathogen Screening
This testing is carried out to assure that the harmful bacteria are not present - not even in very low number or amount. Therefore, the product is enriched by growing in the enrichment broth for seven days so pathogenic bacteria, if present in very low number, will be able to multiply and be detected.
- Total Gram negative Test
includes Pseudomonas aeruginosa, E.coli, Salmonella, Serratia, Enterobacter, Klebsiella pneumoniae and others
- Staphylococcus aureus Test
- Microbial Identification
Once organisms are isolated from a product and a manufacturer wants to know which organisms they are, they order the Microbial Identification Test of their products. Isolates are identified starting with observing their morphology. Isolates are Gram stained and observed under the microscope. This gives an initial clue about whether they are gram negative or gram positive. Isolates are then identified by Commercial identification kits, e.g., API.
- Testing of FDA Hold Products
Accugen Labs, Inc. has numerous years of experience in testing cosmetic products detained by the FDA. Customers' products which are held by the FDA are tested and the reports, along with all the data, are then submitted to the FDA.
- Antimicrobial Preservative Effectiveness Test (Challenge Test)
The antimicrobial efficacy test evaluates the effectiveness of an antimicrobial preservative in the health, beauty, personal care, or cosmetic product. The test is carried out in such a way that the product is challenged with the known strains of the microorganisms. Personal care and cosmetic testing samples are tested at different intervals to determine the survival of the organisms. The test demonstrates the efficacy of the product to stop the growth of pathogenic organisms like Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Candida albicans, and Aspergillus niger. The microorganism survival is monitored for 28 days.
At least 100-150 mL or grams of the product are needed to run this test.
