Alfaparf Milano launches its Precious Nature Color Line- free from Ammonia, PPD, and resorcinol. This line is made up of five color families, all containing a unique ingredient depending on the color.
All 49 shades are based with sugar and rice milk. Sugar helps provide shine and rice milk has nourishing properties. The natural color family is made with reparative chestnut; cool browns are made with hazelnut for protection; warm browns are made with caramel for a more intense color; blondes are made with honey with conditioning properties; and reds are formulated with cherries for antioxidants.
Precious Nature formula’s consistency is rich and creamy and is gentle. The key element is the creamy activator, which is made from ingredients that make the color formula gentle on the scalp.
Precious Nature will be available in September. 2017
Why you want to limit contact with resorcinol.
Endocrine Disruption: Evidence from case studies, animal studies and in vitro studies demonstrates that resorcinol disrupts thyroid function and that can manifest in hyperthyroidism and an enlargement of the thyroid gland also known as a goiter.
Resorcinol has been shown to have two different effects: 1) the inhibition of enzymes involved in thyroid hormone synthesis; and 2) the activation of thyroid hormone receptors. Several studies indicate that resorcinol inhibits the activity of enzymes responsible for important stages of thyroid hormone synthesis. The enzymes are responsible for incorporating iodine in the creation of thyroid hormone. If the enzymes cannot produce thyroid hormone the body will sense a deficiency and secrete thyroid stimulating hormone this will cause the gland to enlarge and will result in a goiter. An study of resorcinol’s effects on cells, suggests that resorcinol acts like thyroid hormone and as an agonist at thyroid hormone receptors at low doses.
Further research is needed to determine whether these different effects are a result of different exposure levels, and whether exposure to resorcinol through hair dye will have a significant adverse effect on the thyroid.
Organ system toxicity: Resorcinol can be acutely toxic in high concentrations or if consumed orally. In these cases of resorcinol toxicity symptoms including convulsions, respiratory failure and cyanosis were reported. There are also effects on the central nervous system including drowsiness, unconsciousness, and seizures, however, there is little evidence that these effects will result from chronic exposure at low concentrations.
Skin irritant and sensitizer: Resorcinol is an acute irritant when in contact with the eyes. There is also evidence that it is a skin irritant and sensitizer. Few reactions occur when the concentration is under two percent, but higher concentrations lead to increased number of reactions.
VULNERABLE POPULATIONS: Hair stylists/colorists
REGULATIONS: Restricted in all types of cosmetics in Japan, The EU limits maximum concentrations and requires warning labels. The United States regulates the exposure to resorcinol for workers in certain manufacturing fields as well as in coal processing (resorcinol is a byproduct of coal manufacturing), but not among salon workers.
HOW TO AVOID: Limit hair dying. Read labels and avoid products that contain resorcinol, 1,3-benzenediol, resorcin, 1,3- dihydroxybenzene (m-hydroxybenze, m-dihydroxyphenol)
