High SPF Sun Care Guide: Formulation & Testing for Compliance

Achieve high SPF & good UVA ratings with improved skin feel while minimizing actives in your sun care product formulation

Julian Hewitt will help you find ways to make actives more efficient and share practical strategies to help boost SPF: UV filters selection (organic, inorganic), rheology & film forming, photostability, cost, water-resistance...

Get your sun care cosmetics to comply faster with today’s UVA/SPF regulatory requirements by upgrading your testing strategy to overcome challenges resulting from the lack of global harmonization of test protocols and labelling criteria.

Julian Hewitt will help you avoid running expensive tests and show you how to support formulation work & UVA / SPF claims for your targeted markets (EU, US, Japan). You will learn about conducting right test at the right time (in-vitro or in-vivo) & how to interpret test results better.

Course Outline

• Module 01:

  The following sections will be covered during this session:

• Module 02:

  Summary of performance measures for sun protection products

• Module 03:

  In-vivo SPF and UVA testing

  • Basic Principles
  • Comparison of different in-vivo SPF test protocols (ISO 24444, ISO 24442, FDA 2011...)
• Module 04:

  In-vitro SPF and UVA testing

  • ISO 24443 procedure
  • FDA Final Rule of 2011
  • Critical Wavelength Test Parameters
• Module 05:

  Advantages and disadvantages of in-vivo and in-vitro testing

• Module 06:

  Global regulatory requirements – what tests are required and/or accepted in different countries/regions

• Module 07:

  Optimizing your test protocols - questions to consider when test results do not match expectations:

  • What should I do when my formulation:
    - Fails to meet my SPF target?
    - Meets my SPF target but fails the UVA/broad spectrum test?
    - Meets my SPF target when tested in-vitro, but fails the in-vivo test?
    - Meets SPF and UVA targets on initial screening, but now fails the final in-vitro UVAPF test (ISO 24443)?
