QUERATAN
HYDROLYZED KERATINCAS: 69430-36-0 EINECS: 274-001-1
INTRODUCTIONKeratin is an insoluble fibrous protein, of high
molecular weight. Keratin is composedby a sequence of 18 amino
acids interlinked by hydrogen, salted and disulphidebridges.
Keratin is the major constituent of hair and nails, and its
physicochemicalcharacteristics are responsible for tissue
properties.
PROPERTIESQueratan is an hydrolyzed keratin solution of low
molecular weight. A carefulhydrolysis process results in amino
acids and small peptides.
The ability in penetrating hair cuticle is due to their low
molecular weight. Queratanrestores, hydrates and imparts gloss and
softness to damaged hair.
Queratan is water soluble, and is easily incorporated in hair
and nail careformulations.
INDICATIONSQueratan is specially indicated in formulations for
hair and nails treatment. Hair andnail appearance and vitality
depend on the integrity, moistness and electric chargedistribution
located along the keratinized fibers. Preparations containing
Queratan willhelp restoring regions where peptidic chain has been
damaged by aggressive agents.
Conditioning effect is attributed to the re-equilibrium of water
content, distribution ofelectric charge and to a balanced pH.
Queratan is soluble in water, alcohol 50%, and has good
compatibility with anionics,cationics, anphoterics and non-ionics.
It may be incorporated in shampoos,conditioners, capillary
reconditioners and nail care formulations. Suggested
concentrations are:
shampoos 1 to 3% conditioners and hair straightners 2 to 5%
capillary reconditioners 3 to 6% nail care formulations 2 to 5%
