Propylene glycol is an ingredient commonly found in several personal-care products like shampoo, hair conditioner, as well as styling products. Propylene glycol is extensively used because of its reasonably inexpensive and also versatile nature. Its addition in a formula can accomplish a range of purposes, which makes it a prominent option by many cosmetics chemist. However, some suppliers have actually lately made the decision to no more make use of propylene glycol in their items.
As a parent, I take caution to what I use in my children’s hair care, so when I read about Propylene glycol, I freaked out! This article is meant for you if you too are always on the lookout for natural hair care and ways to eliminate the possibility of unmitigated exposure to toxins contained in hair care products.
Do not be distressed by the term antifreeze or by the chemical, propylene glycol It is risk-free at the reduced concentrations when utilized in personal care products.
This is potentially over-exaggerated because of misinformation and also publicity circulated on the web for advertising and marketing “all-natural” items.
I like to think am a serious advocate of natural products, avoiding putting toxins into our bodies whenever feasible or sensible. It’s extremely discouraging to see how the dissemination of inaccurate and insufficient information in an effort to discourage customers into making use of different items. In this article, I look at a better way to clarify and clear up some false impressions regarding this chemical.
The Chemical Facts Concerning Propylene Glycol.
It is water-soluble.
It is synthetic.
It is safe.
It is easily metabolized.
Propylene glycol (which is also commonly called 1,2 propanediol) is a fairly tiny molecular agent with two alcohol (hydroxyl) teams (- OH). It is a colorless, odorless fluid that is completely water-soluble. PG is a synthetic product acquired from the hydration of propylene oxide, which is stemmed from petroleum items. I do not directly consider a petroleum-sourced product to be a poor thing, as I consider the last structure and also its composition to be more pertinent than the source (unless contamination is an issue in the first place).
The FDA has classified propylene glycol as “Generally Acknowledged as Safe.”
Despite having extended straight exposure, there is little to no skin irritability or sensitization. It subsides rapidly once the area is purged. The MSDS advises staying clear of straight handling because of prospective irritability, which is a smart recommendation for any chemical– this is not an indication of the degree of toxicity. Remember: in the chemical market when a worker is exposed to continual as well as big quantities of a chemical in its concentrated type, it is crucial to use the strongest security precautions possible. This is not pertinent to consumers making use of an item by the teaspoonful, if that same chemical is used.
Propylene glycol is non-toxic when consumed, even in fairly big amounts.
Unlike its hazardous as well as often lethal relative, ethylene glycol, PG is conveniently metabolized by the liver right into regular items of the citric acid metabolic cycle, which are totally harmless to the body. Approximately 45 percent of any kind of consumed PG is secreted directly from the body and also never ever enters into the liver.
The removal for propylene glycol is about 4 hours, and there is no bio-accumulation (buildup in the body gradually). A couple of unusual incidents have taken place where an individual ingested a huge quantity of propylene glycol and experienced some liver and neurological problems as a result, but these were short-term and also diminished as soon as the material was metabolized and eliminated.
molecular structure of Propylene glycol
The metabolic cycle for propylene glycol
Propylene glycol → lactic acid → pyruvic acid → CARBON DIOXIDE + water
Both speculative and also unscientific evidence to this day show PG to be entirely non-carcinogenic, in spite of its “petroleum-based” origin. In an intriguing research study, some rats were fed propylene glycol at amounts equal to 5% of all of their food consumption everyday for two years, which is a quite massive volume over a big section of their life time. There were no observable impacts on their health and wellness or habits.
What “antifreeze” actually means for customers
Words are regularly utilized to alarm customers, as well as is merely a clinical term made use of to describe the reducing or anxiety of the freezing factor of a liquid. An example is the application of salt to roadways as well as pathways in a snowstorm. This procedure helps melt snow and ice as well as prevent advancement of unsafe icy problems. The salt achieves this by reducing the cold point of water.
This is an example of a “secure” chemical being used as antifreeze. Do not be surprised by the term antifreeze or by the chemical, propylene glycol. While couple of chemicals are totally without danger, propylene glycol is taken into consideration to be safe at the reduced concentrations, used in personal care items or even food products
Propylene glycol in personal care products.
It is an efficient humectant.
It is a solvent for scents as well as chemicals.
It can be utilized as an emulsifier or co-surfactant.
It is utilized as a solvent for pigments in cosmetics.
It can be used as a chemical as a result of its antifungal as well as antimicrobial residential properties.
It is frequently used in antiperspirants .
It is commonly found in hand cleansers as well as disinfecting gels.
It is an usual additive in shaving creams and gels.
I think for those of us with curly haired kids, propylene glycol’s major benefit is the fact that it is a humectant, and a very reliable one at that.
Just how propylene glycol affects hair
It applies like a humectant (draws in water to the hair).
It will not create build-up.
It will not vaporize easily (which triggers dry hair).
The application of propylene glycol that is most pertinent to those of us with curly hair is as a humectant. All the usual warnings for use with regard to its abilities to draw in water to the hair from the setting or to draw water from the hair to itself. Unless you have the excellent weathers, you may experience problems with this ingredient.
Propylene glycol is a totally water-soluble material that will not build up on the hair. It is likewise crucial to keep in mind that it is a diol with low volatility, indicating it will certainly not evaporate quickly and cause completely dry hair in the manner of low molecular weight alcohols such as SD alcohol and isopropyl alcohol.
Final verdict: Do not fear propylene glycol
Propylene glycol must not be a feared active ingredient. If product manufacturers are finding substitute components to satisfy the very same functions in their solutions served by propylene glycol, I see no harm in that. Nevertheless, I support and promote materials that contain and use propylene glycol.
