7-year-old Madison Gulliver has a severe reaction to “Black Henna” whilst on holiday.
This news story is only one of many alarming and saddening stories to have been reported over the past couple of years and highlights just how important it is to know exactly what is going on our skin.
Cliff Betton, Chairman of Delphic HSE had this message to all regarding PPD in Black Henna:
Paraphenylenediamine – PPD for short – is an industrial chemical. It is a simple compound, with a structure as shown below, but one that is very reactive and is used in the manufacture of polymers, linking the components together thus forming many useful materials.
Its’ reactivity is also useful in hair dyes where it is used to link the pigments used to colour hair, to the protein of the hair structure itself, giving a permanent hair colour.
In Europe, the use of PPD in cosmetics and hair dyes is strictly controlled by Law: the concentration is limited to 3% on hair and 2% on eyelashes and appropriate warnings along with recommendations for testing before use are given.
The ability to bind to proteins is what makes PPD useful, but it is also what makes PPD dangerous. As PPD can bind to proteins, there is a possibility that if used in large concentrations, it could penetrate the outer dead layer of the skin and bind to proteins within the skin itself. This binding then changes the structure of the protein and that protein becomes – as far as the body’s immune system is concerned – no longer part of you, but is seen as an invader, like a virus or bacteria, the body’s own defence mechanisms are activated to fight what is now seen as a serious threat.
Because PPD is an industrial chemical, it is comparatively inexpensive and this is where the problem lies. It can dye the skin effectively, but if used without restrictions, it may – and does – start an immune reaction, often after a single contact. In some areas of the world, temporary tattoos, of the type that are commonly to be found at the beach, are not controlled by law and can contain up to 30% + of PPD. A single contact can cause the catastrophic injuries shown in the news. These can and often do lead to permanent scarring. And even if no immediate reaction is caused, the single application of a temporary tattoo on holiday can induce an allergy that then lies dormant until the next time the body encounters PPD, may be years later at a visit to the Hair Dresser. The great majority of people who react to hair dyes in fact have had previous exposure to black henna tattoos obtained on holiday.
PPD is a useful chemical and is present in many hair dyes, but as with all things, the dose makes the poison, and getting a temporary tattoo on the beach, may give rise to pain and scarring that will last a life time. Stay safe, do NOT get a temporary tattoo anywhere that you cannot be certain that the product is safe.”
Delphic HSE fully support the voice of the UKs cosmetics industry the CTPA (Cosmetic, Toiletry & Perfumery Association) in their view on “Black Henna”. Please look at the link below by the CTPA.
If you have any concerns at all arising from this news story then please feel free to contact Delphic HSE.
The safety assessment of cosmetic raw materials is very important – it helps formulators to develop a safe product at the very early stage of product development.

There is currently no EU-wide legislation regulating tattoos and permanent makeup, meaning consumers are only protected by the General Product Safety Directive.

This year, Delphic HSE can announce that we’ve entered into a Primary Authority Partnership with Buckinghamshire and Surrey Trading Standards (BSTS). This is a big development in Delphic’s ability to give industry-leading advice on cosmetics regulatory compliance.
