M/389 - Sunscreen products

This standard specifies a method for the in vivo determination of the sun protectionfactor (SPF) of sunscreen products. It is applicable to products that containany component able to absorb, reflect or scatter ultraviolet (UV) rays and whichare intended to be placed in contact with human skin.This document provides abasis for the evaluation of sunscreen products for the protection of human skinagainst erythema induced by solar ultraviolet rays.

This document provides a basis for the evaluation of sunscreen products for the protection of human skin against erythema induced by solar ultraviolet rays.

This test method provides an in vitro procedure to characterize the UVA protection of sunscreen products. Specifications are given to enable determination of the spectral absorbance characteristics of UVA protection in a reproducible manner. In order to determine relevant UVA protection parameters the method has been created to provide a UV spectral absorbance curve from which a number of calculations and evaluations can be undertaken. Results of this measurement procedure can be used for other computations as necessary for local regulatory authorities. These include calculation of Ultraviolet-A Protection Factor (UVA-PF) (correlating with in vivo UVA-PF from Persistent Pigment Darkening testing procedure), Critical Wavelength, and UVA/UVB absorbance proportionality. These computations are optional and relate to local sunscreen product labelling requirements.

ISO 24443:2012 specifies an in vitro procedure to characterize the UVA protection of sunscreen products. Specifications are given to enable determination of the spectral absorbance characteristics of UVA protection in a reproducible manner.
In order to determine relevant UVA protection parameters, the method has been created to provide a UV spectral absorbance curve from which a number of calculations and evaluations can be undertaken. This method relies on the use of in vivo SPF results for scaling the UV absorbance curve.

This International Standard specifies an in vivo method for assessment of the UVA protection factor (UVAPF) of topical sunscreen products. This International Standard is applicable to cosmetics, drugs and other products intended to be topically applied to human skin, including any component able to absorb, reflect or scatter UV rays. It provides a basis for the evaluation of sunscreen products for the protection of human skin against UVA radiation from solar or other light sources.

ISO 24442:2011 specifies an in vivo method for assessment of the UVA protection factor (UVAPF) of topical sunscreen products. It is applicable to cosmetics, drugs and other products intended to be topically applied to human skin, including any component able to absorb, reflect or scatter UV rays.
