Cosmetics — Analytical methods — Nitrosamines: Detection and determination of N-nitrosodiethanolamine (NDELA) in cosmetics by HPLC, postcolumn photolysis and derivatization

Document Number: NL ISO 12787 : 2017

This International Standard describes a method for the detection and quantification of N-nitrosodiethanolamine (NDELA) in cosmetics and raw materials used in cosmetics by high performance liquid chromatography (HPLC) coupled with post-column photolysis and derivatization. This method is not applicable to the detection and/or quantification of nitrosamines other than NDELA, nor to the detection and/or quantification of NDELA in products other than cosmetics or raw materials used in cosmetics. If a product has the possibility of either NDELA contamination from the ingredients or NDELA formation by the composition of ingredients, the method will be applied for the testing of cosmetic products and is an alternative to ISO 15819. This method is not applicable to matrices containing oxidation dyes.

This Technical Report covers the reduction or elimination of adventitious nitrite sources, reduction or elimination of secondary amino sources, incorporation of inhibitors to N-nitrosamine formation and analytical methodologies for total N-nitroso compounds and specific methods for N-nitrosodiethanolamine (NDELA).

Cosmetics — Analytical methods — Nitrosamines: Detection and determination of N-nitrosodiethanolamine (NDELA) in cosmetics by HPLC-MS-MS

Document Number: NL ISO 21148 : 2017

This International Standard describes a method for the detection and quantification of N nitrosodiethanolamine (NDELA) in cosmetics and raw materials used in cosmetics. This method is not applicable to the detection and/or quantification of nitrosamines other than NDELA nor to the detection and/or quantification of NDELA in products other than cosmetics or raw materials used in cosmetics. If a product has a possibility of either NDELA contamination from ingredients or NDELA formation by the composition of ingredients, the method is intended to be applied for quantitative determination of NDELA. Accordingly, the method does not apply to routine testing of cosmetic products. Because of the large variety of cosmetic products within this field of application, this method might need to be adapted for certain matrices (refer to ISO 12787). Therefore, International Standards dedicated to alternative methods for testing nitrosamines in cosmetic products are being developed separately. Other methods can be employed provided that they are verified as to their detection of NDELA and validated in terms of recovery and quantification of the analyte.

It is applicable to SPF and UVA protection, and both in vivo and in vitro methods. This Technical Report does not include the aspects of labelling in a wide sense.

Cosmetics - Determination of sunscreen UVA photoprotection in vitro

Document Number: NL ISO TR 17276 : 2017

This International Standard 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. Results from this measurement procedure can be used for other computations, as required by local regulatory authorities. These include calculation of the Ultraviolet-A protection factor (UVAPF) [correlating with in vivo UVAPF from the persistent pigment darkening (PPD) testing procedure], critical wavelength and UVA absorbance proportionality. These computations are optional and relate to local sunscreen product labelling requirements. This method relies on the use of in vivo SPF results for scaling the UV absorbance curve. This International Standard is not applicable to powder products such as pressed powder and loose powder products.

Cosmetics — Analytical approach for screening and quantification methods for heavy metals in cosmetics

Document Number: NL EN 14901 : 2017

This Technical Report introduces most common and typical analytical approaches for screening and quantification of heavy metals of general interest at both raw material and finished product level. This Technical Report covers techniques from traditional colourimetric reaction, which can be executed without expensive instrument to the high-end one, like that of inductively coupled plasma-mass spectrometry (ICP-MS), which allows detection of elements at μg/kg level. Thus, this Technical Report covers the advantages and disadvantages of each analytical technique so that a suitable approach can be chosen. The intent of this Technical Report is not to set or suggest acceptable concentration limits of heavy metals in both raw materials and finished products which have to be determined by each regulatory authority. NOTE 1 The term “heavy metals” is widely used without single definition. NOTE 2 Elements can be specified as heavy metals by one legislation, while not by others.
