Cosmetics Active Ingredient Analysis

Control of cosmetics and personal care product active ingredients such as preservatives, vitamins and sunscreens are detailed in regulations and guidelines including the EU Cosmetics Regulation (EC) 1223/2009 driving the need for robust analysis and testing

Analysis and testing of cosmetic active ingredients are key to innovative performance, product quality and safety. However, the inclusion of some active substances is subject to global regulations such as the EU Cosmetics Regulation (EC) 1223/2009 pertaining to quality and dosage levels. Manufacturers, distributors and importers of personal care products must ensure that they satisfy these guidelines. Ensuring the correct dosage of active ingredients is also critical to how the product performs. Innovation is driving the exploration and use of novel actives and bioactives in formulations to help address functional performance areas such as anti-ageing, even skin tone, brightening, UV protection, moisturizing, elasticity and can include peptides, vitamins, preservatives and more. These innovations and regulatory challenges drive the need for expert analysis and testing to determine the levels and quality of these cosmetics active ingredients. 

Expert Cosmetic Active Ingredient Analysis 
Our scientists provide chemical and biochemical testing services, experienced method development, and technical support, to help you to ensure that products meet quality standards and comply with global regulations. We provide a wide range of active ingredient analyses including preservatives, vitamins and sunscreens.

Hyaluronic Acid
Hyaluronic acid (HA) is an active ingredient used in dermal fillers, wrinkle-filling gels, visco-supplements in cosmetics and medical devices to address skin aging. Understanding the quantity, purity, physico-chemical properties, chemical composition and microbiological properties of HA are critical to supporting product development and control the quality of raw materials. We provide a complete set of analytical testing and microbiological lab services to help you characterise and ensure quality of your HA materials and formulated products.

Preservative Analysis 
Preservatives prevent cosmetic product contamination from micro-organisms during storage and continued use by the consumer. Strict rules govern the inclusion of preservatives with regard to the concentration used in the formulation. Our scientists provide broad testing expertise for the levels of preservatives in products including the dosage of these preservatives: 

  • Parabens (methylparaben, ethylparaben, propylparaben, butylparaben)
  • Phenoxyethanol
  • Triclosan
  • Methylisothiazolinone and methylchloroisothiazolinone (MIT/CIT)
  • Proxel (BIT)
  • Benzyl Alcohol
  • Chlorhexidine
  • Sorbic acid (and its salt, potassium sorbate)
  • Benzoic acid (and its salt, sodium benzoate)
  • Dehydroacetic acid (and its salt, sodium dehydroacetate)
  • Salicylic acid 

Vitamins Quantification
An increasing number of antioxidants, vitamins and bio-active ingredients are used in personal care products to help repair skin and hair damage. Examples of vitamins and bio-active ingredients routinely tested include Vitamin A Retinol, Vitamin pro A Carotene, Vitamin B1 Thiamine, Vitamin B2 Riboflavin, Vitamin B3 Nicotinic Acid, Vitamin  B3 Nicotinamide, Vitamin B5 Pantothenic Acid, Vitamin pro B5 Panthenol and more. 

Sunscreens (and UV Filters)
Both chemical and physical sunscreens are used in cosmetic products to protect the skin from exposure to harmful UV rays. Chemical filters are powerful absorbers of both UVA and UVB rays. Physical sunscreens reflect and scatter UV light. Examples of the sunscreens routinely tested:

Chemical Sunscreens: 

  • Benzophenone Phenylbenzylimidazole sulphonic acid
  • Octocrylene Ethylhexyl methoxycinnamate
  • Ethylhexyl triazone 4-methylbenzyllidene camphor
  • Butyl methoxydibenzoylmethane Diethylamino-hydroxybenzoyl-hexylbenzoate

Physical Sunscreens:

  • Titanium Dioxide
  • Zinc Oxide
