algae - the ingredients:Ø mineralsØ carbohydratesØ fatsØ amino acidsØ vitamins
algae - the health-promoting effects:Ø activates the cell metabolismØ re-mineralises the skin through the mineral saltsØ anti-inflammatory and antipruriginous propertiesØ successfully applied in treatment of neurodermatitis and
psoriasisØ protects skin from free radicals and harmful environmental
impactØ detoxifying and purging effect on the human body due to the
high absorbency and active ingredients of the seaweedØ beta-carotene contained in the seaweed is used in cancer

Ø The minerals contained in the seawater accumulate in theseaweed. This explains the large variety of chemicalelements found in seaweed material. Moreover, theycontain carbohydrates, amino acids, fats and vitamins.
Ø Analyses of the the fibre and the aqueous extracts of thefibre showed that the active ingredients of algae material are also contained in fibres and fabrics.

SeaCell® fibre is able to release minerals gradually; this special propertyof SeaCell fibre and fabrics still remains intact after repeated washing.

SeaCell® fibre and fabrics made of SeaCell® contain the vitamins of thealgae material, with the exception of the water-soluble vitamin C.
Ø The active ingredients are not destroyed during the fibremanufacturing process.
Ø The active ingredients are incorporated in the porous fibrematrix.
Ø The minerals and vitamins are released from the fibre in a humidenvironment.
Ø The textile fibre properties of the SeaCell® fibre are compareable tothose of standard Lyocell fibres.
Ø The fibre is manufactured using the product and environmentalfriendly Lyocell technology.

Ø The bioactive substance of SeaCell® active is silver
Ø Small portions of silver-ions are released by the fibre matrix
Ø Silver-ions pass the cell-walls of micro organisms
Ø Killing of micro organisms by blocking their cell-functions

Baseline 100% SeaCell® active
Ø no need of organic compouds (pesticides)
Ø silver: harmless - skin compatible
Ø effective - even after frequent washing
Ø the outstanding properties of cellulosic fibres (wear comfort) arealso typical for SeaCell® active fibre
Ø excellent physical properties are not affected by the addition of silver
Ø textiles with a low quantity of silver - against neurodermatitis
Ø first cellulosic fiber with an antibacterial and fungicidal effect

several testings
Toxicity testing of a material extract ( ISO 10993-5):
Ø a method to differentiate between reactive and non reactive (fibre) materialsØ to get information about the biocompatibility of different materials
SeaCell® pure + SeaCell® active… cytotoxicity
Source: Fa. Cytox
Testing process:
Ø Preparation of extracts of SeaCell® pure und SeaCell® active
Ø Incubation of the extracts on L929 mouse fibroblast cells (48 h)
Ø Determination of protein content in the mouse cells after incubation
Results:
SeaCell® pure and SeaCell® active do not cause cytotoxic effects.
