Can glycerin, which is included in the composition of the Feminum intimate gel, contribute to the appearance of an intimate infection?

Indeed, in many places you can come across information that glycerin can be the cause of intimate infections and mycoses. However, I do not find scientific publications that would exclude glycerin for use in intimate gels and confirm unequivocally that it can cause diseases. Perhaps the information that glycerin can have a negative effect on the microbiome of the vulva and vagina is due to the fact that it has a sweet taste, so it is considered a sugar that could be a breeding ground for microbes. However, glycerin is not a sugar, but a sugar alcohol (sugar). It is not toxic and is widely used in cosmetology. However, the origin of glycerin and the osmolarity of the lubricant may be of some importance, unfortunately this information is generally not provided by the manufacturer. Gels with high osmolarity can in some cases cause irritation and pH disturbances, which could indirectly promote infections. According to the World Health Organization publication, many lubricants for personal use have osmolarity of 2000-6000 mOsm/kg, while the normal osmolarity of vaginal secretions is 260-290 mOsm/kg, semen - 250-380 mOsm/kg. It also recommends that lubricants should not have an osmolarity higher than 1200 mOm/kg ("Use and procurement of additional lubricants for male and female condoms: WHO/UNFPA/FHI360"). If you are prone to intimate infections, it is best to be careful and use products such as intimate gels moderately. If poor tolerance of the preparation is observed, it can be replaced with another (e.g. without the addition of glycerin and preferably also without additional auxiliary substances). However, the addition of ingredients such as lactic acid, affecting the reduction of pH, may be beneficial.
