Criteria for obtaining AllergyCertified certification

If you want your products to be AllergyCertified you must be aware that there are specific chemicals which are never allowed. These are ingredients which are known to be allergenic like perfume, and specific preservatives such as Methylisothiazolinone and Formaldehyde and its donors.


General requirements

In order to be AllergyCertified a product needs to pass an allergy risk assessment. For this assessment we need full information and knowledge about the product. The information needed for the allergy assessment is: A copy of the products safety assessment, and  INCI names/chemical names, CAS numbers, the exact concentrations[1], information about impurities and MSDS. A trusted toxicologist makes the allergy assessment and all information given to this person will be held confidential and only be used for the assessment. If needed we can make a secrecy agreement for this.


Chemicals not allowed

Chemicals classified with these R and H- sentences are generelly not allowed in AllergyCertified products unless the chemical is used in a specific product or in such low concentration that the SCCS and/or our advisory board assess it as safe.

Sensitizing and skin effect :

R42 May cause sensitisation by inhalation

R43 May cause sensitisation by skin contact

H310 Fatal in contact with skin.

H311 Toxic in contact with skin

H312 Harmful in contact with skin

H314 Causes severe skin burns and eye damage.

H317 May cause an allergic skin reaction



R40 Limited evidence of a carcinogenic effect

R45 Limited evidence of a carcinogenic effect

H350 May cause cancer .

H351 Suspected of causing cancer .



R60 May impair fertility

R61 May cause harm to the unborn child

R62 Possible risk of impaired fertility

H360 May damage fertility or the unborn child

H361 Suspected of damaging fertility or the unborn child



R38 Irritating to skin

H315 Causes skin irritation

-Depends on the type of product (leave on, rinse off and the used concentration)


AllergyCertified products are not allowed to contain (negative list):

Perfume (Alpha isomethylionone, Amyl cinnamal, Amylcinnamyl alcohol, Anise alcohol, Benzyl alcohol, Benzyl benzoate, Benzyl cinnamate, Benzyl salicylate, Butylphenyl methylpropional, Cinnamal, Cinnamyl alcohol, Citral, Citronellol, Coumarin, Limonene, Eugenol, Evernia Furfuraceae (træmosekstrakt), Evernia prunastri (egemosekstrakt), Farnesol, Geraniol, Hydroxycitronellal, Isoeugenol, Hexyl cinnamal, Hydroxyisohexyl 3-cyclohexene carboxaldehyde, Linalool, Methyl 2-octynoate and all other perfumes whether they are synthetic or natural).


Formaldehyde donors:




Diazolidinyl urea

DMDM hydantoin

Imidazolidinyl urea



Sodium hydroxymethylglycinate


Other preservatives

Methylisothiazolinone (MI)

Methylchloroisothiazolinone (MCI)

Kathon MI/MCI

Plants from the Compositae or Asteraceae family are generally not allowed (examples on allergenic plant from this family could be)

Chamomille retutica




Metals in colorants, some colorants can contain nickel or other allergenic metals. For these ingredients we need documentation that the level of the metal in the product is safe (NOAEL) for consumers who have already been sensitized to the nickel (the metal)

Acrylates, some specific acrylates such as Methaacrylate are not allowed. If the acrylate is an impurity in another chemical we an only allowed if there is a NOAEL value and the impurity is below this value


Preservatives allowed in AllergyCertified products (positive list)

(Some are depended on concentration)

Benzoic acid

Dehydroacetic Acid





Potassium Sorbate

Sodium Benzoate

Sodium Sulfite

Sorbic Acid


Oils allowed in AllergyCertified products:

(for some of the oils we do need documentation for purity)

Aloe Barbadensis (depending on the level of Antraquinone)

Butyrospermum Parkii Butter

Brassica Campestris Oleifera

Borago Officinalis Seed Oil

Brassica Oleracea Italia

Brassica Napus Seed Oil

Elaesis Guineensis Oil/Elaesis Guineensis kernel Oil

Hydrogenated Canola Oil

Olus Oil

Olea Europaea Oil

Prunus Amydalus Dulcis Oil

Prunus Armeniaca Kernel Oil

Persea Gratissima

Ricinus Communis Oil

Simmondsia Chinensis Seed Oil

If you want to use an oil thats not on the list, then you can give us the INCI name and CAS number and we  will find out if it has allergenic potential or not.

[1] Since Contact Dermatitis can depend on the concentration of the chemicals that we get exposed to, we need the exact concentration of the ingredient in order to do our assessment.
