Cosmetics - Sun protection test methods - In vitro determination of sun protection factor (SPF) (ISO/FDIS 23675:2024)

This International Standard specifies a method for the in vitro determination of Sun Protection Factor. This International standard is applicable to sunscreen products with an emulsion chassis, which are intended to be placed in contact with human skin.

Kosmetische Mittel - Untersuchungsverfahren für Sonnenschutzmittel - In vitro Bestimmung des Sonnenschutzfaktors (SSF) (ISO/FDIS 23675:2024)

Dieses Dokument legt ein Verfahren zur In-vitro-Bestimmung des Sonnenschutzfaktors (SSF) fest. Dieses Verfahren gilt für Sonnenschutzmittel in Form einer Emulsion oder einer alkoholischen Einphasenrezeptur, ausgenommen Sonnenschutzmittel in Form eines losen oder gepressten Puders oder Stiftes. Es werden Spezifikationen angegeben, die eine reproduzierbare Bestimmung der spektralen Extinktionseigenschaften des SSF-Schutzes ermöglichen.
Dieses Verfahren dient ausschließlich der Bestimmung eines statischen Sonnenschutzfaktors. Für die Bestimmung der Wasserbeständigkeit eines Sonnenschutzmittels ist es nicht anwendbar.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
