Cosmetics Laboratory Testing

At Ullmann analytical lab, cosmetic analysis is one of our primary areas of expertise. Our cosmetic scientists are fully staffed for seven days of operation. Ninety percent of our analyses are performed on a daily basis. Our high quality instruments such as liquid chromatography, gas chromatography and ion-chromatography are used for the assay and purity of active ingredients.

All raw materials must be tested:

  •  Free of pathogenic microbiological contamination. (Microbiology page linked).
  •  Free of Inorganic impurities such as lead, arsenic, mercury, and heavy metals as per USP, FCC and CTFA requirements. (Pharmaceuticals arsenic, etc. linked).

Below maximum allowable limits of organic contamination such as residual solvent, 1, 4-dioxane, formaldehyde, phthalate, and nitrosamine.

Cosmetic Labeling Requirements: Products that are cosmetics but are also intended to treat or prevent disease, or affect the structure or functions of the human body, are considered also drugs and must comply with both the drug and cosmetic provisions of the law. Examples of products which are drugs as well as cosmetics are anti-cavity toothpastes (e.g., “fluoride” toothpastes), suntanning preparations intended to protect against sunburn, anti-perspirants that are also deodorants, and antidandruff shampoos.

ULPL offers a variety of microbiological services, such as testing and analyzing products ranging from raw materials to finished goods from a broad range of industries. Our microbiology department is staffed with scientists experienced in testing AOAC, FDA, USP, and other internationally harmonized methods of microbiological testing.

ULPL has provided microbiological services to pharmaceutical, disinfectant, cosmetic, personal care, over-the-counter, dietary-supplement and many other industries.A more detailed list of the new USP <61> and <62> can be found below. Effective May 2009, the new USP <61> and <62> provide harmonization to the existing European Pharmacopeia method for testing non-sterile pharmaceuticals.

USP <61> Microbial Enumeration Tests such as total aerobic microbial count (TAMC), and total yeast and mold count (TYMC). The Microbial Enumeration Tests' changes lude new pass/fail criteria, longer ubation durations, and the disallowing of retests. Negative control is now required every time that the product is tested. Organism validation in TSA plates have changed to Staphylococcus, Pseudomonas, and Bacillus subtilis.

USP <62> Microbiological Examination of Non-Sterile Products: Tests for Specified Microorganisms. The modifications on microbiological medias for specific pathogens like Salmonella, Pseudomonas aeruginosa, Staphylococcus aureus, Escherichia coli, Clostridia, bile–tolerant Gram-negative bacteria, and Candida albicans. Critical changes have been made to enrichment broth, ubation temperatures and ubation duration. Organisms such as Candida albicans, Clostridia species, and bile-tolerant Gram-negative bacteria may be required to be tested depending on product type per FDA and USP monograph. Negative control is required everytime that the product is tested.

Fruits Laboratory Testing

ULPL Food Testing Service - Food Product Testing involves multiple steps of sample preparation and tedious extraction. Due to the complicated nature of the food product matrice, our food testing group performs the quality control testing on food raw material and finished goods from sweet tooth snacks such as cake, cookies, candy, yogurt or ice cream; starch carbohydrate sources such as rice, noodles, and pie; beverages such as juice, mixed drinks, wine or beer.

Ullmannlab has implemented continuous training on laboratory techniques, instrumentation, technical knowledge, preparation and extraction skills. Ullmann Laboratory performs Raw Material Quality Testing according to published FCC (Food Chemical Codex published by USP) and UNICEF FAO published methods.

Nutritional Label Claims

The Nutritional Labeling and Education Act (NLEA) of 1990 mandated nutrient labeling on almost all foods and food supplements sold in the U.S.

The trans fatty acid rule was added to Nutrition Facts panel compliance, effective from January 1, 2006. ULPL adopted AOAC International's and other companies' published equivalent methods for nutritional labeling.

This includes vitamin analysis by HPLC, cholesterol by gas chromatography, fatty acid profile, and methyl ester gas chromatography.

Proximate Analysis:

  •  Calories
  •  Moisture
  •  Protein
  •  Fat
  •  Ash

Nutrition Facts Label package listed below

Calories Cholesterol Vitamin C
Calories from Fat Dietary Fiber Sodium
Protien Saturated Fats Iron
Carbohydrates Total Fat Calcium
Sugars Vitamin A (Retinol and Beta carotene)
Monounsaturated Fats Trans Fats Potassium
Polyunsaturated Fats Other Carbohydrates

  •  Moisture by LOSS ON DRYING and Karl Fisher methods may be necessary, se high moisture content reases the possibility for bacterial and mold propagation.
  •  Testing for other impurities in raw material, for example food alcohol, should not have residual toxic contamination of methanol, acetone and Isopropyl alcohol.
  •  Sugar and sugar alcohol must check for purity such as glucose, dextrose, sorbitol manitol and maltitol.
  •  Dried food sources such as fish or anchovies should check for histamine or other amines, se the presence of histamines are a sign of spoiled fished protein.
  •  For raw materials not listed in FCC, check the USDA and FDA food safety suggestions.
