How can I access toxicological datasheets?

There are two way to visualize toxicological datasheets of interest:

  • By clicking the Menù item "NOAEL-search". The search-panel will open and the user will fill the box named INCI name with the desired INCI or, in alternative, the box named Substances with same NOAEL or CAS number with the CAS number or the INCI of the substance of interest. The autocomplete function is only available in the first box: if you don't see any suggestment after typing a name, please click the Apply button anyway; results will be shown below.

After this step, if records are found, you will see a table with all the ingredients meeting the search criteria (depending on the search words, results could be very redundant). All the entry are visible as links to the relative datasheet.

  • By clicking the Menù item "Substances list" and browsing the alphabetically ordered list to spot the desired ingredient. The link is visible only for the substance for which a NOAEL was found, the other INCIs listed below inherit the same tixicological evaluation.

How can I calculate the MOS for a given substance?

The user should keep in mind that the MOS value has to be calculated for every substance employed in the cosmetic formulation.
To calculate the MOS, the NOAEL should be divided by the SED (see FAQ section for more info).

In the "Downloads" section of the website the registered user can download an excel file already filled with example values in order to set the calculation on hiw substance of interest.

How can I calculate the SED for a given substance?

NOAEl-project provides an excel template where is possible to calculate the SED value in two diffrerent ways.

In any case you need the dermal absorption value (expressed as % or as μg/cm2) to calculate the SED; if this parameter is missing, a SED equal to 100 must be used.
In the first sheet the "Calculated relative dayly exposure" will be automatically filled after the user has selected the cosmetic category of interest (body lotion, shampoo ...). In order to calculate the SED, the user has to manually insert the concentration in the cosmetic product (this value must be a number between 0 and 100, where 100 corresponds to 100%) and the dermal absorption expressed as %.

In the second sheet of the same excel file, the user can calculate the SED only if the dermal absorption value (espressed as μg/cm2) is available; all the other values needed for calculation are automatically retrieved from the table on the right.

How the NOAEL-project's toxicological data-sheet is organized?

NOAEL-project toxicological datasheet (see an example at this link) is articulated in the following sections:
 
Substance identification
 
INCI name: the INCI name of the substance employed in toxicological studies that were used to identify the NOAEL reported
CAS number: all the CAS number for all the substance to which the chosen NOAEL can be extended
Substances with same NOAEL: the corresponding list of INCI name for the CAS numbers reported previously
Missing tests: list of missing endpoints required by SCCS to achieve a complete toxicological profile
Extract: indicates wheter a substance is an extract or not
Extraction source: the source from which the extract is obtained (fruit, leaves, flower...)
Extraction solvent: the solvent used to obtain the extract
Active ingredients: the list of active ingredients present in the extract with a link redirecting to their toxicological datasheet

Substance of reference for read-across: list of substances already present in the database employed to retrieve the NOAEL for the substance of interest
 
Optional fields

Annex number: if the substance is included in an Annex, this field show the Annex number, otherwise it shows the "Not in Annexes" label
Restrictionsif the substance is included in an Annex, this field shows the restrictions as reported by the SCCS

 

Chemo-physical properties section

INCI name: INCI name of the substance for which the info below refer
Log P: Partition coefficient of a substance in a mixture of 1-octanol/water
Molecular weight: Moleular weight of the substance
Dermal absorption: This value is always expressed as % and can be found in toxicological studies (specifically, in the pharmacokinetics section) or estimated following SCCS assumption that, if the molecular weight is equal or greater than 500 da and the Log P is <-1 or >4, the substance has a dermal absorption of 10%.
Dermal absorption 
(μg/cm2): dermal absoprtion expressed as μg/cm2, a parametere required in order to calculate the SED if dermal absorption (%) is missing
 

Toxicological profile of the substance

NOAEL: The NOAEL value expressed as mg/kg * bw/d
Test duration: Time of application of the substance expressed as days (d) or months (m)
Test type: Type of toxicological assay from which the NOAEL reported was retrieved
Animal model: the animal employed in the test from which the lowest NOAEL was chosen
Route of subministration: The route of subministration used in the toxicological assay

 
Quality system: This field indicates if the test employed to assess the NOAEL were conducted following OECD Principles of Good Laboratory Practice (GLP), OECD guidelines or other reliable but not GLP-compliant guidelines
Source: The source from which the reported NOAEL was retrieved, it can be an online toxicological database or a scientific journal
Notes: A field where additional toxicological endpoints such as mutgenicity and genotoxicity are described ando/or where the choise for the NOAEL reported is discussed in details.
