The EU Nickel Directive

As a result of various problems associated with Nickel sensitisation in clothes and jewellery, the European Community ( EG ) Nickel Directive ( 76/769/EEC ) was enacted on 20th July 1999, and was set to become law in the EU on the 20th January 2000.

The Directive was devised due to fears about allergic reactions and sensitisation to Nickel, and has been designed to reduce any problems caused by this material.

By January 20th 2000 the Nickel Directive is law in the EU

There is no ambiguity – any supplier or shop saying this Directive is not a law is misguided or covering up, they may be hiding something. It is the law – do not buy anything from such people, it is your responsibility.

The directive is a large document but it is simply put as:

Items intended to come into contact with broken skin are restricted to a mass of 0.05 % Nickel. Items intended to come into close and prolonged contact with skin are restricted to a release rate of 0.5 h g/cm2/week of Nickel.

316L Surgical Steel contains between 6-13 % Nickel and it does not conform to the first part of the Directive and it cannot be used for fresh piercings. It can only be used after the healing process has taken place as replacement jewellery since it does not release Nickel. Titanium does not contain Nickel but can attract it during the manufacturing process. Titanium does conform to the first part of the Directive but may not conform to the Nickel release Directive.

Wildcat Implantanium® has been developed as an alternative to titanium in the search for a low nickel alloy containing less than 0.05% nickel by mass (500 parts per million), to meet the new criteria for implantable body jewellery.

Implantanium® is legal for all piercing applications worldwide.

Titanium

Titanium is the wonder metal of the technological age, possessing a myriad of fascinating characteristics in many forms. Titanium is used for armour plating on military vehicles, deep sea submersibles, computer chips, architectural reconstruction (including the Pantheon) nuclear storage systems, ballistic armour, medical devices, pacemakers, heart valves and in many other applications. An innovative titanium nickel alloy can actually remember it's original shape and return to it, even when severely deformed. The energy required to produce one ton of titanium from it's ore is 16 times that needed to produce one ton of steel, hence it's higher market valuation. Titanium is now also playing a major role in the body piercing jewellery market.

Because of three main characteristics, titanium is now challenging steel as the most favoured metal in the body piercing industry. Titanium is only half the weight of steel and can be anodised (thus offering a wide spectrum of surface colours). Primary piercing with nickel alloyed metals is outlawed in all EU countries with the passing of community wide legislation during 1999 - 2000. Not all grades of titanium or it's alloys are suitable for invasive body piercing jewellery applications. In the latest American Society for the Testing of Materials Titanium Textbook, there are no references to commercially pure titanium for surgical applications in over 1,000 pages of technical data (CP Titanium grades 1, 2, 3 and 4)

Wildcat are using Grade 23 surgical Titanium (specification Ti6AL4VELI) for all new titanium jewellery products. This is a grade recognized worldwide for medical devices. Heart valves, pacemakers and replacement human body parts are being made from Grade 23 titanium and are satisfactorily implanted into millions of people.

All Wildcat jewellery is made from G23Ti. It is highly polished for physiological acceptance and and decorative effect and comes in a sparkling spectrum of vivid colours. G23Ti can be used for all primary piercings in accordance with the European Union Nickel Directive. All jewellery has a super smooth surface and extreme chemical stability.

The passive oxide film on G23 Titanium is almost three times thicker than on "commercially pure" Grade 1 Titanium, (83A compared to 32A). It is the oxide film on titanium with an extremely low solubility and high protective ability which invests the material with it's high corrosion resistance properties.

Silicone

Wildcat Northern Lights range are all PMMA, glow in the dark and Ultra Violet reactive.
All pieces have passed EN71 Part 3 testing to ensure safety, a toy standard to chemical content. This is a recognised safety toxicity test.
They are however not designed for permanent wear or implantation.

Silicone Specification

Wildcat glow in the dark silicone accessories have been tested to conform with EN71 part 3 safety toy standard. This is the heavy metal analysis which is used for toy regulations to ensure safety if put into the mouth. The silicone to which the pigment is added is the medical grade as used in baby teats, diving masks etc and complies with the standard 29 days body contact as laid down in EN 30993.

However, as with all silicone pieces, they are not designed for permanent wear and are recommended for occasional use.

Blackline

Metal Specification

Since its first introduction to the medical device industry in the late 1980's, Physical Vapour Deposition (PVD) has become widely used to deposit wear resistant, thin film coatings onto medical devices (including pacemakers, surgical instruments and orthopedic implants.) The main value in PVD technology rests in the ability to modify the surface properties of a device, without changing the underlying materials properties and biomechanical functionality. Wildcat are now using this advanced technology as a surface enhancement on medical grade titanium.

Biocompatibility
(Tripartite protocol for materials that experience body contact) Sensitisation: Non sensitising (No delayed dermal contact sensitisation)
Cytoxity: Non Toxic - No evidence of causing cell lysis
Mutagenicity / Genotoxicity: Non - Mutagenic.
Acute systemic toxicity (T12): Non Toxic.
UPS muscle implantation (T14): Non-irritating to muscle tissue.
Intracutaneous Toxicity: No tissue reaction.
Hemolysis: Non-hemolytic, compatible with blood.
Important Information
Rouge Manufacturers and pathetic imitators of wildcat products are "passing off" black surface coated jewellery as "Blackline". Many of these products may be seriously dangerous.

All Wildcat Blackline (TM) involves the PVD coating on a G23 medical substrate. Cheap imports and even some western products, have a carbon compound layer on 316L surgical steel. Carbon on such a substrate will accelerate the corrosion of the steel. No such reaction is possible with Wildcats G23 titanium substrate. Disseminating corrosive materials can bring enormous legal consequences and assumes unlimited product liability. Carbon is also a totally unique element, with over a million known existing compounds.

Some carbon materials suffer from a lack of permanent integrity: particles can migrate and become entrained in blood, fibres & filaments can be shed from composites and migrate into the lymphatic system. Just because the body jewellery is black, it does not mean it is Blackline (TM). Wildcats PVD formula is proven biocompatible.

Wildcat Blackline (TM) is safe for invasive piercing jewellery and is scientifically supported.

Stainless Steel

Iron based alloys have a medical history extending over three hundred years (in 1666 Fabricus described the use of wire hoops for wound closure, and in 1886 Hansmann reported the use of steel sheet for fracture fixation). In 1916, corrosion resistant stainless steels were developed (containing a minimum of 10.5% chromium) and this unique surgical implant material evolved. (Stainless steels achieve their inert characteristics through the formation of an invisible and adherent chromium rich oxide surface film). In 1947, the American College of Surgeons recommenced stainless steels for biomedical implantation applications.

Stainless Steels are categorised into four general classes, based on composition: 200 series steel contains chromium, nickel and manganese, 300 series steels contain chromium and nickel, 400 series steels contain chromium and 500 series steels contain low chromium. The most corrosion resistant steels are the 300 series steels and hence their popularity for medical implants and body jewellery. However, not all 300 series steels are suitable for invasive body piercing applications. Wildcat use three surgical steels for body jewellery: Composition D Implantation Steel, 316L Surgical Steel and 316LVM Surgical Steel. Although these high grades all contain nickel, they do not release nickel salts into the body and do not induce contact nickel dermatitis. Wildcat have independent laboratory testing certification on file indicating that nickel evolution is below 0.01ug/cm2/week. All steels supplied by Wildcat meet the annex Criteria in the EU Nickel Directive and can be supplied, indefinitely, world-wide for all secondary piercing applications.

Surgical Stainless Steels (316L) are used for bone fixation screws, body pins, bone plates, total joint prostheses, bone nails, wires spin instrumentation, mandibular wire mesh prostheses, endodontic post and cores, sutures, staples, neurosurgical and microvascular clips, intercranial drainage valves and cardiac pacemaker electrodes amongst many other application. Body jewellery on the following pages is manufactured from equivalent (or higher) standard material. We do not play or gamble with your health. Some disreputable suppliers are offering body jewellery made from 303 Stainless Steel (a high sulphur, easy machining steel). 303 Steels elicit negative reactions in nickel sensitive persons (14% in test studies) and should be avoided at all costs. Cheap imported garbage now on the market will contaminate the wearer, permanently. All Wildcat Steels are stable, legal alloys. Our Implantation Steel is twenty times more expensive than 316 grade steels, such is our dedication to providing safe body jewellery.

ELECTROPOLISH INFORMATION:
Many of the following items have been electropolished. Electropolishing is a sophisticated surface finishing technique, where electrochemical activity slowly erodes a thin surface layer from the jewellery resulting in MICROSMOOTHING. High spots and protrusions are removed preferentially. The resultant surface is extremely smooth and crevice free. Surface geometry influences bacterial activity: the ultra smooth and ultra clean surface reduces body rejection possibilities. Electropolished body jewellery has a higher surface integrity and surface efficiency than jewellery polished by other means. For initial implant in new non-epithilized piercings, use Implantanium, Titanium, Niobium, PTFE or higher purity gold. All Nickel holding steels are now outlawed throughout the EU for primary piercing insertables. The Wildcat Collection 2000 E+OE.

Plastastic & Casein

Plastastic ™

Wildcat are now producing a fantastic range of high performance polyester ear plugs called Plastastic™. This special formula plastic is non-toxic and is used in a huge variety of surgical applications, including synthetic artery replacements, absorbable sutres, surgical staples, tendon reconstructions, prosthetic heart valves, ligament restorations, bone plates and screws, surgical mesh abdominal wall reinforcement, replacement bladders, replacement invertebral discs and even neural regenerations (repair of nerve systems).

Plugs are available in a variety of sizes and colours. All plugs are supplied with two nitrile "O" rings and are 15mm in length.

Plastastic ™ of the wildcat collection.

Casein

Casein is a unique material produced by acid precipitation of pure skimmed milk, which has varied applications both as a foodstuff and plastic. Manufactured at only two sites in the world, Casein is powdered between two rollers and laid flat. Only 1mm per week can be laid down for the Casein to bond effectively. A 16mm ear plug takes four months of preparation, followed by a further three months of hardening. The resultant product is inert. No two plugs have the same pattern.

Niobium

Unlike Implantanium®, surgical steel and other implantation alloys. Niobium is a pure element, which cannot be sub-divided into further components. Niobium is always found in ores alongside Tantalum and derives its name from this close relationship. (Tantalum was named after the mythical Greek King Tantalus, whose daughter was Niobe.) Niobium is a reactive metal (along with Titanium, Zirconium and Tantalum, perhaps the four most bio-compatible elements on the planet) is designated by the chemical symbol Nb and has the atomic number 41.

Although used extensively in the Gemini Space Programme, Niobium is widely used as a body implant material. Niobium exhibits excellent corrosion resistance properties only in a high purity form (99.9% minimum.) Wildcat use high purity Niobium for body jewellery.

It exhibits a rich oxide surface film which passivates the material in any Oxygen environment and allows for a vast array of surface colours. Overwhelmingly proven to be chemically inert, in-vitro and in-vivo studies have confirmed the excellent short and long term bio-compatibility performance of Niobium. Niobium Isotopes are now being used as diagnostic aids, in radiotherapy and for cardiac imaging and blood flow studies.

Niobium is less popular than Titanium for use in body piercing jewellery, due to its higher density and greater weight.. One advantage of the metal over Titanium is the ability for the metal to appear black: Charcoal is an anodised colour, whereas matt black is heat generated and therefore considered permanent. All other colours are the result of electrolytic anodization: The transparent surface oxide film generates interference colours, giving the illusion of colour change in much the same way as oil on a wet street - the colours are actually tricks of light refraction (no pigments are added.)

Baltic Amber

All products in this section are carved with genuine Baltic Amber. except AIP which is 50% Baltic Amber 50% synthetic amber combination. Amber began its incredible evolution some one hundred million years ago. In what was then a sub-tropical climate, trees oozed resin which polymerisated over thousands of years to become a substance known as copal. During this phase the molecules begin to cross chain link and form strong bands. Copal contains many volatile oils in the form of turpenes. Over a period of many millions of years, the volatile oils which were trapped in the resin evaporate until amber is formed. The surface of amber readily oxidises in air.

Amber can be found in many colours (white, yellow, brown , red, blue and green), although its common appearance is as a golden resin. Amber found on the Isle of White in the UK has been proven to be 120,000,000 years old. Formations discovered in the Lebanon have been determined to be 125,000,000 years old. Amber is not derived from the sap of trees (which is a watery substance containing many complex sugars), but from the resin, which contains succinic acids. Amber is considered chemically inert and is widely used for body piercing jewellery items.

Mammoth Ivory

All Wildcats mammoth ivory is extracted from the permafrost tundra of North Eastern Siberia, a vast desolate wasteland deep inside the Arctic Circle. The Russian academy estimates that more than 500,000 tons of mammoth tusks are buried along a 1000 kilometre stretch of arctic coast. Annually some five tons of ivory are taken from the ice. Fast flowing rivers, fat with melted snow, are flushing massive tusks from this icy mausoleum as they carve their way through a landscape frozen for one million years since the dawn of the first ice age. Ice layers more than 1.5 km thick erode to reveal their fascinating secrets.

This new availability of mammoth tusk makes any illegal trade in elephant ivory obsolete and should now end the obscene trade in elephant ivory products on the black market.

Ebony & Ivory

Genuine ebony & Ivory jewellery. Alternating slices of fossilized Mammoth Ivory and Black Ebony combine to make jewellery of unprecedented character and quality. All jewellery is imported under CITES control and under license from the British Government. The Ivory is Siberian Mammoth Ivory and is supplied with a certificate of origin from the Department of Trade of the Russian Federation. All Ivory has been frozen in the ice for tens of thousands of years and therefore should not be autoclaved or heat treated.

Gold

Wildcat are pleased to launch an extensive range of exotic body jewellery in 14kt & 18kt gold. 14kt gold is the most appropriate standard for threaded piercing jewellery, the metal being strong enough to maintain the threaded features even after repeated usage. 18kt gold is inappropriate for barbell usage, the softness of the material wearing out the threads after repeated removals. All gold items on the following pages are either 14kt (584 gold) or 18kt (750 gold). No nickel is added as a stabilizing agent in any product. All products are hand made by skilled craftsmen and are not mass produced in Chinese factories.

Important: 9kt Gold body jewellery can seriously affect your health

9kt gold (375 gold) is only 37.5% gold and 62.5% impure alloying metal. Anecdotal, empirical and clinical evidence indicates biological rejection of this low grade material. Dental experts have recently published clinical data confirming that the corrosion resistance of gold alloy decreases significantly as the gold content is reduced. Whereas high Nobel alloys resist deterioration and degradation, low gold alloys corrode significantly and release metallic ions directly into the body tissues, contaminating the wearer. Dental gold is regulated by ISO 1562, stipulating specific alloying elements. 9kt gold does not meet this criteria and is not considered suitable for implantation. Furthermore, Norwegian research indicates that people with dental gold restorations become hypersensitized to low quality gold (25% by sample) and develop a permanent gold allergy. Beware of suppliers offering 9kt gold body jewellery: It may permanently have an adverse affect on your health.

Wildcat do not supply 9kt gold invasive body jewellery.
