“The Beauty” Cocktail: Propylene Glycol, Triethanolamine, Parabens.
Different diets, fruits, vegetables, fresh juices, fitness and swimming pool – we study methods and techniques, spend a lot of money because we are accustomed to associate all this with a healthy lifestyle, maintaining our youth and beauty. However, when it’s about cosmetics everything is different – by our polls a very small amount of people reads the full ingredients list, they limit themselves to a prudently his proposed list of “active ingredients”.
While it is no longer a secret that modern cosmetics mainly composed of water and products of chemical & petrochemical synthesis.
It is enough to just quickly read this paragraph:
Methyl – Propyl – Isopropyl – Butyl – Ethyl – Parabens; Imidazolidinyl Urea, Diazolidinyl Urea, 2 – Bromo 2 -Nitropropane-1, 3-diol and other Formaldehyde – releasing preservatives; Methylchloroisothiazolinone and other Isothiazolinone-derived biocides; Phenoxyethanol; Triethanolamine, DEA; Propylene Glycol, PEG; Mineral Oil, Petrolatum; Isopropyl Alcohol; Stearalkonium Chloride, Sodium lauryl sulfate (SLS), Diethyl& Dibutly phthalate, Fragrance, Dyes et cet.
Looks impressive right? – preservatives, emulsifiers, synthetic oils, stabilizers, enhancers, fragrance), dyes. All this and similar ingredients play a main role in the production of billions of tons of cosmetics by hundreds of different brands. Cheap technology for mass production.
Petroleum is product of nature that makes those components also partly natural, say proponents of the use of these components.
Well, imagine a bartender suggesting you a cocktail which consists of the components described above. Would you try?
Not everything that has been created by nature, you can eat, drink or apply on the skin. Opponents say that there is low-concentration of each of these components contained in these cosmetics. What about daily use for many years? Changing one brand to another, these same “base components” can be applied on the skin for decades.
Useful, natural, nutritional for skin? The Choice is Yours.
Constantly smoking and drinking alcohol can also be some time without visible effect.
There is no conclusive evidence of harmful effects and people just copy each other’s statements on the internet without evidence? Let’s check it out. For example, a very wide spread preservatives – Parabens.
The preservatives – biocides are not only allergens, but are really able to penetrate the stratum corneum, in contrast to most “active ingredients”. The study, which was published in the article “Concentrations of parabens in human breast tumours “(Darbre PD, at al, Journal of Appl Toxicol. 2004 Jan-Feb; 24 (1):5-13.) demonstrated a high concentration of parabens in breast tumors tissue.
In 2012, a new study was published: “Measurement of paraben concentrations in human breast tissue at serial locations across the breast from axilla to sternum” (L Barr, at al. Journal of Applied Toxicology, Vol. 32, (March 2012), p.219 -232). The result was the discovery of one or more species of parabens in 99% (158 of 160) of tumor tissue samples, and five species of parabens were found in 60% of cases.
Based on these studies, is it possible to accurately claim that parabens were one of the causes of cancer, or with the same сonfidence deny it? No you can not – either affirm or deny.
Is it worth your life and health of a definitive answer?
That’s a good question.
There is no need to list in details the consequences of the application of these basic components of mass cosmetics. There is a lot of information on the Internet, and indeed often without reference to serious studies.
Here are the names of only a few research articles to this subject, which speak for themselves and causing a question – whether the use of these components is an “extreme sports” but without any chance to get at least one good benefit for your health?
