The list of all our tests
ISO 24443: 2021 is the official method for in vitro UVAPF measurement, and it gives in
vitro SPF value, UVA-PF value, and critical wavelength. These measurements provides
precious information about the formula such as the absorbance according to wavelength,
the photostability of the filters and the SPF/UVA-PF ratio, and is timesaving and cost
saving for the development of your formula before starting in vivo testing.
Photostability is an important parameter for both final products and raw materials, to ensure
the properties of the product will remain the same through time, from efficiency to
organoleptic aspect. Photostability is necessary to take into account to choose the right
packaging for your product. Tests are performed using our xenon lamp.
The photostability test with daylight completes the solar simulator test. Some
compounds are extremely sensible to light.
Substances used in cosmetic formulation, especially vegetable oils, are sensible to oxidation
and can release free radicals and alter the integrity of the formula. This test shows the
presence of free radicals in the product without treatment and the possible release of free
radicals during exposition to xenon lamp.
Sebum is a natural component of the skin but excess of sebum is not appreciated. A direct
measure of sebaceous glands secretion using a photometric method determines the sebum
level of the skin and scalp, the importance of sebum reduction and how long the effect
last. This is the ideal test for sebum reduction skincare and mattifying powders or clay
masks.

This is the ideal test for sebum reduction skincare and mattifying powders or clay masks.
Melanin and hemoglobin are the two chromophores responsible for skin color and
radiance. With our in vivo colorimeter we can measure the color parameters of a specific
area and melanin and erythema index. With this test we are able to evaluate the effect of
your product on skin lightness (scrubs, peelings, anti-dark spots), anti-redness properties
and long lasting wear of make-up and self-tans.
With the ultrasound aspect of the skin we are able to measure the skin thickness and its
density, by sending an acoustic signal to the skin. This signal will be retransmitted and
absorbed according to the structure of the skin. This device also allows to visualize the
different layers and to see the density of the dermis with the collagen network.
Ideac
Elasticity loss is one of the main characteristics of skin aging. The elasticity of the skin is
determined before and after the application of a cosmetic product. A suction cup measures
the necessary force needed to lift the skin a certain distance using negative pressure, and
the retraction time it takes for the skin to retract when the pressure is released.
TransEpidermal Water Loss is the other main parameter after measurement of hydration to
study for products targeting skin moisture. We measure the quantity of water evaporating
the skin superficial layers and the impact of the product on the reduction of water loss.
Moisturizing effect is one of the primordial properties of a cosmetic product. We measure
the effect on the product on stratum corneum conductivity and how long the effect last.
We use Dual Laser Confocal Microscopy (DLCM) to observe the different layers of the
epidermis, dermal-epidermal junction, papillary dermis and reticular dermis. This
technology allows us to visualize different structures: keratinocytes, melanocytes, dermal
papillas, blood capillaries and collagen fibers.
We perform several measures according to your needs and requests to assess the properties
of your products on collagen synthesis, on the aspect of keratinocytes, and with the
counting of red blood cells passing through blood capillaries we are able to quantify the
effect of the studied product on local microcirculation.
To evaluate the reduction of wrinkles or the smoothing effect of a formula on fine lines,
we take prints of the skin surface and measure the depth and width of the relief with our
Scanning Electron Microscope (SEM). This test suits especially anti-aging cares, primers
and moisturizers.
The hair volume test is indicated for hair products especially, but also for other products to
visualize the effect of the formula on keratin cuticles. Aspect and width of a hair are
measured by observing the sample with our Scanning Electron Microscope (SEM) to
provide high precision values.
Zeta potential is the particle charge in colloids, nanoparticles and biomolecular
particles. It helps to anticipate the stability of emulsions and suspensions, but also to
determine the skin diffusion factor, the ability of a formula to vectorize actives through the
different layers of the skin. Because of the skin surface electronegativity, compounds that
are also electronegative will flee the surface by penetrating through the different layers of
the epidermis. On the contrary, electropositive compounds will remain at the surface of the
skin. Zeta potential is generally measured at skin physiological pH 5,3 to predict the
behavior of the product on stratum corneum, pH 6 and plasmatic pH 7,38 to predict the
behavior of the product around the eye area or within the cells. Zeta potential
measurements are fast and help you to save time during your stability studies.
Knowledge about the rheological behavior of raw materials or finished products is
essential to forecast how the product will behave in storage and at the time of application in
terms of texture and spreadability. Depending on the nature of the product, the rheometer
analyzes viscoelastic properties, gel strength, stability and thixotropy.
Surface tension is the property of a liquid to shrink into the minimum surface area and to
form droplet. This parameter completes the knowledge on spreadability and wetting
properties of a raw material or finished product.
Differential Scanning Calorimetry is used to follow a product behavior depending on
temperature and highlights physicochemical properties such as melting point,
recrystallization point, oxidation induction time, glass transition or degradation. It also
gives information about the impact of storage conditions on products and to predict the
product behavior on the skin.
Volatility is measured to know how prone is the product to vaporize into ambient air. It is
essential information for the choice of the right packaging.
Dynamic and kinematic viscosity are complementary analysis used to measure the
resistance to deformation of fluids at a given velocity gradient and gravitational force. They
are used to characterize raw materials or finished products.
Flash point is the lowest temperature at which a combustible material ignites for
selfsustaining combustion in ambient air. The flammability tester covers a wide range of
temperatures (-30°C to 400°C) and tests according to standardized methods for the
cosmetic industry (ISO 2719). All types of materials can be analyzed, allowing being
compliant with transport regulation.
Density and refractive index of liquid or fluid compositions are one of the basic
measurements to characterize and compare different products.
PSD measures the size of the particles in a powder sample and the distribution of
different sizes. It allows enhancing rheology performance of final compositions.
Raman spectroscopy is a diffusion spectroscopy, which allows characterizing the
molecular composition and the external structure of a material, and is complementary to
IR spectroscopy.
The UV spectrophotometer gives quantitative results about the absorption spectrum
depending on wavelength of raw materials and finished products. It is used to determine
chemical functions, identify impurities and compare different compounds.
The infrared spectrophotometer is used to characterize and control of chemical
compounds or finished products by measuring their absorption in the IR spectrum,
especially to determine the chemical functions of a product and to identify an unknown
product or impurities.
Osmolality is the concentration of particles dissolved in a fluid. Osmotic pressure is the
phenomenon that regulates the fluid exchanges between intra and extracellular
compartment. The respect of plasmatic osmolality is therefore important to ensure the
good hydrating properties of a skincare, and especially to ensure it doesn’t damage the
cells.
Tribological properties are studied to determine the friction and lubrication behavior of
a cosmetic product on skin surface. It is essential to compare texture and spreadability
performances between products, and completes rheology analysis.
The measurement of the Oxidative Stability Index gives indication in the resistance of
fats and oils to oxidation. These data allow the screening of antioxidants, optimization
of mixtures, shelf-life determination and products valorization, in order to select the
best lipophilic ingredients, to create safe and efficient cosmetic products.
Sensory analysis provides you precious information about the organoleptic properties of
your products, in all its dimensions: visual, olfactory, and touch. With sensory analysis we
compare your products to a benchmark or between them, describe their characteristics
and score and rank them.
The penetrometer is used to determine the plasticity and resistance to deformation
(penetration) of pasty, creamy, semi-solid or highly viscous samples against the application
of force. It can be used for the evaluation and analysis of raw materials or finished products.
Penetrometer is complementary with DSC to measure hardness of waxes, lipsticks or lip
balms.
