PHYSICAL-CHEMICAL / INSTRUMENTAL TESTS

XENON TEST
Purpose of the test is the simulation of the exposure to solar radiation (UV, Visible and IR) of cosmetic products, to verify the stability of the color and any other organoleptic property.
ACCELERATED STABILITY TEST COSMETIC PRODUCT
The test allows evaluating, in vitro, the stability of the chemical-physical-organoleptic-microbiological characteristics of a cosmetic product, by exposing it to conditions of accelerated aging that simulate its natural aging (4 weeks of accelerated aging = 1 year of natural aging).
ACCELERATED STABILITY TEST MEDICAL DEVICE
The test allows evaluating, in vitro, the stability of the chemical-physical-organoleptic-microbiological characteristics of a medical device by subjecting it to conditions of accelerated aging that simulate its natural aging (12 weeks of accelerated aging = 1 year of natural aging).
NATURAL STABILITY TEST (SHELF LIFE)
The test allows evaluating, in vitro, the stability of the chemical-physical-organoleptic characteristics of a sample, subjecting it to natural aging.
STABILITY TESTS AND CONTENT-CONTAINER COMPATIBILITY OF COSMETIC PRODUCTS
The test allows evaluating, in vitro, the stability and compatibility of the content with the relative container by subjecting the product in inert containers and glass (stability) and in the sales package (content-container compatibility) to accelerate aging conditions that simulate its natural aging (4 weeks of accelerated aging = 1 year of natural aging).
STABILITY TESTS AND CONTENT - CONTAINER COMPATIBILITY OF MEDICAL DEVICES
he test allows evaluating, in vitro, the stability and compatibility of the content with the relative container by subjecting the medical device in inert containers and glass (stability) and in the sales package (content-container compatibility) to accelerate aging conditions that simulate , in vitro, its natural aging (12 weeks of accelerated aging = 1 year of natural aging).
EVALUATION OF STABILITY AFTER OPENING (PAO) BY ACCELERATED AGING TESTS
The test allows evaluating, in vitro, the stability after opening of a cosmetic product subjecting it to conditions of accelerated aging, simulating, in vitro, natural aging and repeated opening/closing as a normal use (4 weeks of accelerated aging = PAO 12 months).
IN VITRO DETERMINATION OF THE UVA PHOTOPROTECTION OF A SUNCREEN PRODUCT
The test allows determining in vitro the UVA protection factor of sunscreen products. It is based on the evaluation of UV transmittance through a thin layer of sun-protected product coated on a rough substrate (PMMA plates), before and after exposure to a controlled dose of radiation, resulting from a defined UV light source. A series of calculations allows determining the static SPF value, the UVAPF value (UVA protection), the SPF / UVAPF value and the critical wavelength.
Generally, as a first step, a screening is performed (3 readings) and, if satisfactory results are not obtained, it is possible to block the test at this preliminary level, otherwise the test is continued by performing all the expected readings (definitive test).
DETERMINATION OF THE "LARGE SPECTRUM" PROTECTION
The test allows determining the "broad spectrum" protection by evaluating the critical lambda (≥370 nm = broad spectrum) according to the procedure "IN VITRO broad spectrum test procedure 21 CFR 201.327(j).
IN VITRO PRELIMINARY EVALUATION OF THE UV-HEV-VIS-IR PROTECTION (190-900 nm) OF A SUNSCREEN PRODUCT
This is an in vitro test that allows evaluating, at a preliminary level, the protective action of a cosmetic product against the specific radiation (UV-HEV-VIS-IR) by spectrophotometric evaluation of the absorption in the wavelength range 190 -900 nm.
IN VITRO PRELIMINARY EVALUATION OF WATER RESISTANCE (WR)
This is a screening test, and it provides a preliminary instrumental evaluation of the water resistance (WR) of a sunscreen product.
IN VITRO PRELIMINARY EVALUATION OF WATER RESISTANCE (Very WR)
This is a screening test and it provides a preliminary instrumental evaluation of the water resistance (Very WR) of a sunscreen product.
IN VITRO PRELIMINARY EVALUATION OF CHLORINATED WATER RESISTANCE
This is a screening test and it provides a preliminary instrumental evaluation of the chlorinated water resistance (CWR) of a sunscreen product.
IN VITRO PRELIMINARY EVALUATION OF SALT WATER RESISTANCE
This is a screening test and it provides a preliminary instrumental evaluation of the chlorinated water resistance (SaltWR) of a sunscreen product.
IN VITRO PRELIMINARY EVALUATION OF ARTIFICIAL SWEAT RESISTANCE
This is a screening test and it provides a preliminary instrumental evaluation of the artificial sweat resistance of a sunscreen product.
VISCOSITY, DENSITY AND PH MEASUREMENTS
We carry out measurements of viscosity, density and PH on cosmetic products with appropriate instruments.
THE BOOTS STAR RATING – MEASUREMENT OF UVA:UVB RATIOS ACCORDING TO THE BOOTS STAR RATING SYSTEM – 2011 REVISION
This test is an in vitro method used to describe the ratio of UVA to UVB protection offered by sunscreen products and it allows to classify the product with star rating systems; the final outcome of this evaluation can be no stars, 3, 4, or 5 stars.
