At IMS, our mission is to generate highly predictive SPF and UVA data for our clients, rapidly and at modest cost. We do not offer dozens of different assays. Instead we have focused our research efforts on in vitro SPF and UVA testing both static and water resistance. We are committed to offering the highest quality data and the best possible service to our clients.

• For color comparisons
• To test make up removal properties of facial cleansers
• For lipstick pay-out, wear and durability evaluation

• Assess color development of prototype formulations and raw materials
• Easily follow color development via reflectance measurements (using a color probe)

Are you working to develop Suncare products that deliver superior waterproof performance? Are you responsible for developing new waterproof raw material and formulation technology? Do you wish that there was a rapid in vitro waterproof method that correlated with in vivo testing?

• One IMS in vitro SPF/UVA testing protocol
• Two 22 cm x 27 cm (8.5″ x 10.5″) sheets of VITRO-SKIN^®
• Four 6 cm x 6 cm sample holders
• Two 35 mm reference holders
• One plastic hydration chamber with two mesh shelves and a spacer
• One plastic covered foam block (to simulate the flexibility of the human dermis)
• Twelve latex finger cots

The quantity of water absorbed by human stratum corneum during product application, rub-out and dry-down impacts on how various emulsions spread and de-emulsify on skin. Our research indicates that water absorption by substrate (either human skin or VITRO-SKIN^®) can have a significant effect on measured SPF and UVA protection factors. Dramatic improvements in the correlation with in vivo testing can be achieved by reproducibly hydrating the substrate prior to product application.

Synopsis

In the last few years, the desire to acquire a tan without sunbathing has grown. In response, many cosmetic companies have produced self-tanning preparations. However, to optimize these formulations, a suitable model to assess the colour induced on the skin remains to be developed. We have developed an in vitro method using a synthetic skin in order to study the efficacy of self-tanning formulations. The in vitro test was then used to study the influence of cosmetic ingredients upon the colour induced by erythrulose- or dihydroxyacetone-containing formulations. Finally, an in vivo study allowed us to relate the results obtained in vitro with those found on human skin. The results show that this in vitro test system is a reliable tool to predict the efficacy of self-tanning products.

Several methods exist that evaluate sunscreens efficacy for ultraviolet radiations (FDA, DIN, COLIPA, Australian standards etc.) and it is generally accepted that the determination of sun protection faction (SPF) on humans is the most reliable one.

SPECTROSCOPY OF SUNSCREEN PRODUCTS: HOW TO EXPLAIN THE SPECIAL SHAPE OF UV CURVES OBTAINED FROM IN VITRO SPF TESTS.
Authors: L. Ferrero, A.M. Orcet, L. Zastrow

INTRODUCTION:
Numerous attempts have been made to understand how sunscreen preparations protect against UV radiations (1)-(4). Normally, the final UV absorption of a sunscreen product should depend on absorption curves of each UV filters placed within the preparation. However, it is now trivial to remark the bad accordance between SPF(s) directly calculated from spectroscopic absorbances of pure UV filters (obtained from dilute solutions and measured in 1 cm quartz

INTRODUCTION:
The use of polymeric additives as raw materials 1, 2, 3, 4, which could increase the SPF value of sunscreens, has grown up much lately.
