The glycerin used in the majority of intimate lubricants as a cosmetic agent is in the sights of bloggers!  Bashing deserved? This is the question of the day: is glycerin dangerous?  Is it necessary  at all costs exclude it from the composition of our intimate lubricating gels?  Infections, fungal infections, irritations, ISTT transmissions are serious alerts that are very often found on the Internet concerning this ingredient with multiple origins and virtues.  What is it really ? Let's get closer first  of the scientific field  and  let's try to find out a little more about this controversial asset that is taking quite a spanking on Instagram right now! This article that we propose to share with you resonates with our glycerin-free algae lubricant, but the purpose of the problem is quite different.  The objective is to quickly dispel these erroneous myths and inaccurate information and to discern the true from the false concerning glycerin, this component  omnipresent in the composition of intimate lubricants.

Identity card of glycerin: make way for science!

What is glycerin?

Glycerin is a cosmetic active ingredient which comes in the form of a colorless, odorless liquid with a viscous appearance. It is also one of the most widely used ingredients in cosmetics and  intimate lubricants, whether conventional or organic.  Glycerin, contrary to popular belief, is an alcohol and not a sugar!

Formula : C3H8O3
IUPAC name : propane-1,2,3-triol
Molar mass : 92.09382 g/mol
INN: Glycerol

Where does glycerin come from, how is it extracted?

She may be : 

  • of synthetic origin , from petrochemical derivatives.
  • of animal origin ,  by saponification of animal fats.
  • of vegetable origin , by saponification of vegetable oils . 

Natural glycerin is obtained during a saponification reaction when fatty acids are separated from oil or fat, glycerin being the residue. From this reaction, many types of glycerin are born on the market with their own specificity, made from animal fat or vegetable oil. Only ultra-pure, medical-grade vegan glycerin should be used to make personal lubricants. This is where things get…let's say sticky! 

In most intimate gels, there is glycerin or glycols and there is no way of knowing what type of glycerin is involved. Manufacturers of products for adults inform very little if not never consumers where their ingredients come from and how they are made and processed. Choice probably comfortable but quite confusing!

In an ecological, proactive and responsible approach, we at YESforLOV always favor the use of glycerin of vegetable origin and if possible organic. However, you are aware that glycerin can have various origins. The controversy over glycerin does not come from elsewhere : the glaring absence of information on the origin of each type of glycerin is inevitably the driving force! 

Does my product contain glycerine or glycerine derivatives?

  • Look at the INCI list: Glycerin, Trimethylene glycol, propanediol, propylene glycol… If you see references that come close to it , don't have any illusions, the glycols are in the game. Do not panic however, no cold sweats to have, vegetable glycerin is not the enemy of your mucous membranes .  

Focus on glycerin in intimate lubricants?

The truth is, high-quality vegetable-derived glycerin is an excellent water-based lubricant . It lasts longer and does not dry out: excellent texture, no sticky residue and the most natural feeling you can get, close to feminine secretions: the quality vegetable glycerin is discreet and knows how to be forgotten. !

What are the benefits of glycerin in intimate lubricants?

Here are three good reasons to use vegetable glycerin in our intimate lubricants . And we said well  “vegetable and in respectable concentration rates”.

  • Moisturizes the intimate mucosa:
    Glycerin is able to retain water, so it will help maintain perfect hydration in the skin. Obviously, it is necessary to respect the recommended dosages otherwise it is the opposite effect which occurs. 
  • Softens and protects:
    Glycerin is an excellent emollient, it will thus help to soften, soften and protect the skin from external aggressions.
  • Lubricates durably:
    Glycerin offers a long-lasting glide, it makes romantic relationships all the more pleasant and long-lasting.

Glycerin is also a solvent for the extraction of vegetable plants. No wonder it 's ubiquitous everywhere! It also plays a preservative role, promoting a certain stability in cosmetics .

What could we blame glycerin for?

In the United States, according to the Food and Drug Administration (FDA), glycerin is "generally recognized as safe when used in accordance with good manufacturing practices"

In case of bad dosage or of a doubtful origin, glycerin can cause irritations and minor allergies. Again, it is important to mention that it all depends on the origin of the glycerin and its concentration in the finished product. Our explanations in detail in the paragraph below: 

Glycerin dramatically impacts product osmolarity which is, in short, the measure of how much moisture a substance pulls from one side of a membrane to the other. If you want to know more about osmolarity, it's here but to put it simply, in the event of the wrong dosage, the lubricant can dry out your membranes, cause irritation and trigger many discomforts caused by osmotic stress which will probably create an imbalance of pH (more info on the importance of pH in this article) . 

According to one study, 86% of the lubricants listed in the WHO study have osmolarity levels well above the “LOVE WITHOUT RISK” limit .

In case of bad dosage, glycerin would be likely to increase the proliferation of a fungus Candida albicans , the main cause of vaginal mycosis.  The so-called poorly dosed glygerine-based lubricants are probably not unrelated to possible mycotic episodes which are therefore not to be excluded since this fungus is naturally present in the vagina! . 

It is clear that an unbalanced environment due to osmotic stress and a dysregulation of the vaginal pH  is a breeding ground for all sorts of troubles. However, glycerin is not a sugar per se and it does not promote the secretion of insulin : the risk of seeing glycerin cause yeast infections is therefore quite low.  To date, no study has shown that properly used glycerin could cause fungal infections. 

Yeast infections are rather caused by several factors including antibiotics that modify the flora of the genitourinary tract, stress, fatigue, lack of hygiene during sexual intercourse or even wearing a swimsuit for too long. wet. :  putting sugar in your vagina can cause a yeast infection, we remind you once again, glycerin is not a sugar but an alcohol! 

How do glycerin-based intimate lubricants
Are YESforLOV tested?

More than 200,000 intimate lubricants from our cosmetics range  glycerin based  are sold every year at YESforLOV and have been for more than 13 beautiful long years.  Our products  do n't have  never encountered any difficulties with its users, no complaint on anything, both on the phenomenon of mycoses and on that of the irritation of the mucous membranes. To date, none of our lubricants have been withdrawn from the market . ! To prove the harmlessness of our intimate lubricating gels , we carry out 2 tests. 

Practical case at your disposal  with the moisturizing mixed lubricant , the best seller and the best of intimate lubricants. 

1st test: An evaluation of the tolerance and irritant potential of the product on vaginal epithelia:

According to a clinical study conducted by an independent laboratory on the moisturizing mixed lubricant , no observations were recorded during this test.  The average Irritation Index is 0. The Moisturizing Unisex Lubricant is also rated as non-irritating. The cell death rate is also zero for a contact time of more than 3 hours. The cytotoxicity of the moisturizing natural lubricant , ie its properties to be toxic for the cells until destroying them, is judged to be low even after 24 hours of exposure .

2nd test: A gynecological test which evaluates the clinical and gynecological tolerance and the acceptability of the product: 

The volunteers evaluated the product on its properties after use over a period of 21 days. According to this test , overall satisfaction is  100%, with all participants wishing to continue using the product. 

Here are the results of the usage test  relating to the efficacy of the product ( positive responses ≥ 75%*): 

    • - The product delivers a feeling of freshness
    • - The product brings a feeling of well-being
    • - The product provides a feeling of comfort
    • - The product moisturizes the external genital mucosa

    • - The product respects the intimate area

The conclusion of  report is that the product offers excellent gynecological tolerance , according to the scale adopted, on the external genital area and excellent cosmetic acceptability, with 100% favorable opinions . 

In the same way, we also tested our gourmet oils on reconstituted mucous membranes.  which contain 95% glycerin and also sugar. According to these irritation tests , gourmet oils are neither irritating nor toxic. On the skin , the irritation index is 0.09 ,  which is very very low  and on the mucous membrane, it can only become so if the product is in contact with the mucous membrane for more than 24 hours.

Which lubricant to choose in case of glycol allergy?

I am sensitive and allergic to glycerin, what advice can you give me and what lubricant should I use? 

  • Test our natural lubricant with certified organic algae without glycerin and iso-osmotic without further delay. 
  • Be careful of lubricants that use glycerine derivatives to hide the presence of glycol.
  • Avoid lubricants that contain sugar such as aspartame or sucrose. 
  • Opt for 100% non-comedogenic silicone lubricants , there is very little risk of allergies . 
  • Ask the brand and its product managers to find out the glycol concentration and the origin of the ingredient. 

Although most decisions and opinions remain  personal, often motivated by previous experience, we have no published or known data to definitively link the use of glycerin lubricants to vaginal infections that we know can be caused in several circumstances. Glycerin is a common ingredient in personal lubricants and great if used prolongs the feeling of wetness and slipperiness. Cheap and singularly lacking in purity glycerin is  the major problem and it is endemic! The sad reality is that most intimate lubricants are of very poor quality!  The price … and the lowest at all costs!  Glycerin has become a risky product due to its obvious lack of transparency in its overall journey, from its often dubious origin to its integration into the lubricant, in an approximate dosage  which is not without danger ! It is high time to put an end to this polemic which has no place to exist : what we need is not to consider glycerin as the enemy of well-being but to have the possibility, the certainty of offering  consumers of high quality lubricants. So, without hypocrisy, absolute transparency obliges, I believe that what we need is transparency on the origin of the ingredients. What we need is to give women the information they need to make informed decisions about their own bodies without resorting to scare tactics. Do you want to know more about lubricants and  find the one that suits you best? Take the YESforLOV quiz. I hope I convinced you ! I hope I have put an end to this debate on glycerin, the latter  can  be used safely in intimate lubricants, during your longest, most satisfying and most pleasurable sexual relations there can be!  In any case, this is what I wish you from the bottom of my heart!
