Allantoin
Allantoin can be found in various different plant substrates such as wheat germ, sugar beer, husked rice and horse chestnut bark. It is used as an important active ingredient in dermo-cosmetics thanks to its capacity to promote rapid cell proliferation, thereby increasing healing speed of inflammations, wound, erythema, burns and ulcers. It boasts excellent moisturising properties, making it a valuable ally in treating dry, atrophic, dull or chapped skin. It also acts as an antioxidant, helping slow the ageing process.
In international pharmacology, its healing, soothing, calming, moisturising and skin repair capacities are well-known.

Allergens in perfumes
An allergen is a substance that although generally harmless to most people, in some allergic or particularly sensitive individuals, it can cause allergic reactions of various types. It must be specified that any reaction depends on both personal sensitivity and the percentage contained in the product and which comes into contact.
Developments in research and analysis methods have enabled the identification of substances potentially responsible for allergies. In actual fact, despite tests guaranteeing skin compatibility of cosmetic products, some substances can still cause an allergic reaction through contact (redness, itching, irritation, etc.) in people particularly sensitive to them.
To this end, the new provisions of Directive 2003/15/EC2 establish the obligation to specify on the cosmetic product label, if any of 26 specified perfumed substances are included. These substances are, in fact, considered to be responsible for the onset of allergic reactions through contact when more than a certain concentration of them is included in the product. This "sensitive" threshold varies depending on whether the product is intended to be rinsed off or not. This obligation can be considered as a public health measure that does not aim to prohibit these substances, but rather to inform consumers about their inclusion in cosmetics.
In actual fact, these substances play a key role as they help give the products containing them a specific aroma. Allergens, which have their own characteristic odour, are amongst the main ingredients of a perfume, which can be defined as a blend of odorous substances (on average from 30 to 50 different substances), used for cosmetic purposes, to make personal hygiene products more pleasant in body care and substances for domestic use.
This provision is very important because on the one hand, it helps doctors, facilitating the diagnosis of allergies through contact, whilst on the other hand it enables consumers allergic to some perfumed substances to identify their presence in products and thereby avoid using them.
Perfumed substances exist in nature, but can also be obtained through synthesis. More specifically, 16 out of the 26 substances identified can be present in their natural state (e.g. essence of rose contains 6 of these allergens in its composition: geraniol, citronellol, citral, eugenol, farnesol and linalool).

Ammonium
Ammonium is a chemical compound with the formula NH3. It is found in small quantities in nature, in volcanic exhalations, in addition to being present in the atmosphere of the sun and other stars. For commercial or industrial purposes, it is obtained by means of chemical synthesis.
It is a volatile substance with a pungent odour that is highly characteristics and irritates the breathing apparatus.It is used in hair dyes to swell the hair and open the scales. In doing so, the pigment can thus adhere to the interior of the hair shaft, making for lasting colour.It can cause allergic reactions or other types of scalp irritation; it irritates skin and eyes in addition to potentially causing asthma and breathing difficulties.
This is why the trend is to replace it with other, less volatile, less irritating substances for the breathing apparatus and skin.
In Vebix Color line products, ammonium has been replaced with ethanolamine (INCI: ethanolamine). This substance has the same capacity to swell the hair but does not have the unpleasantly pungent odour of ammonium.

Anti-ozone complex
INCI: Oxido reductases
Oxido reductase is an enzyme that is naturally present in the organism.
In the field of cosmetics, a biotechnological derivative of the enzyme is used with excellent soothing properties. It acts by protecting the skin from attack by environmental agents, such as ozone, UV radiation and surfactants. It is able to neutralise the oxygen reactive species that cause damages to the dermis and epidermis, resulting in early skin ageing -
Antioxidants
Antioxidants can be defined as substances able to neutralize, even at low concentrations, free radicals and protect the organism from their negative action.

Apigenin
INCI: apigenin
Apigenin is an antioxidant present in the leaves of celery and parsley. Another good, natural source is found in chamomile leaves, of which it is the main active ingredient responsible for its spasmolytic properties. It acts on the hair by stimulating the microcirculation at the scalp and hair bulb, improving tissue oxygenation and the supply of nutrients that are essential to the development and strengthening of the hair follicle, thereby helping increase nourishment and oxygenation that are often insufficient in situations of hair atrophy (poor growth).
