ROSIN! YOU SAID ROSIN!
What is rosin?
What toxic poison hides behind this mysterious name that one hardly dares to whisper. Its mere mention could even, according to some manufacturers or wholesalers of cosmetics, be a harbinger of serious illness and in some cases even premature death. Before rushing to the emergency room, a journey through time and to the heart of things is essential.
Rosin comes from a city in Asia Minor where it was originally produced: Kolophon. Rosin is a resin obtained from the tapping of various conifers.
The composition of rosin varies according to the species of conifers used, the geographical origin, the manufacturing and storage processes. It comprises approximately 90% resin acids and 10% neutral substances.
It comes in a solid and brittle form at room temperature, its color varies from light yellow to dark brown.
TAPPING AND TRANSFORMATION
Tapping consists of harvesting pine oleoresin, healing substance that the pine produces and keeps in reserve in its resin canals. It protects it from external aggressions, insect attacks...
The collected resin is then distilled and transformed into two main products:
– Rosin (about 70%),
– Turpentine Oil (About 30%)
STILL ALIVE ? So let's continue...
ESTERIFICATION
Esterification is the process of transforming pure (allergenic) rosin by distillation, which makes it possible to obtain Rosin Esters.
Depending on the method of distillation, rosin esters will be used in different industries. The most allergenic modified rosins are those modified with maleic anhydride, Abitol®, terpene phenol rosin, polymerized rosin and will be destined for other industries.
On the other hand, rosin modified with glycerol (GLYCERYL ROSINATE) and hydrogenated rosin are, during their esterification, filtered from potentially allergenic agents and have a low sensitizing power. The latter will be retained for the development of depilatory waxes and other everyday hygiene products.
Although industrially processed, these rosins dedicated to the development of depilatory waxes, allow, apart from organic waxes composed of sugar, beeswax, etc., to obtain waxes offering a natural compositionup to more than 90%.
It is clear that we have never read on the front page of a newspaper:
" VALENTINE'S DAY ! SHE DIES AFTER DEPILATION WITH PINE WAX! »
More seriously, on reading these lines, we can legitimately wonder about this avalanche of disinterested warnings which leads to a collective psychosis and makes us lose all judgment.
Why do some manufacturers or wholesalers warn us against the great toxicity of waxes made from pine resin, while fortunately developing ranges of waxes without rosin, with improbable odors and colors, without explaining exactly what are the materials used for the manufacture of these synthetic resins, such as thermoplastic elastomer in particular, components that have nothing natural or green about them.
So certainly, a depilatory wax is a non-penetrating surface product. However, no one would think of removing make-up with a treatment made of plastic. It is therefore surprising that we even dare to offer it to us on other parts of the body in the form of hair-removing waxes, whether they smell good or not.
Far from any parish quarrel, it seemed important to us to refocus the debate and to restore certain truths lost in a multitude of assertions that are involuntarily false or sometimes deliberately distilled.
Epiloderm has always made the choice of vegetable resins for the development of its waxes because nothing and no one other than nature provides quality raw materials. Our hair removal method owes its excellence to this union and to the respect that nature (that of the hair too) imposes on us.
EPILODERM waxes are developed from precise and demanding specifications. All our waxes are developed in accordance with our protocol.
So PINE OR PLASTIC?
Epiloderment yours
