Most lubes contain these four ingredients, none of which are found in Sustain’s lubricant:
Propylene Glycol– Used as a humectant. Found in automatic and hydraulic brake fluid. Used to make industrial anti-freeze and de-icing solution for cars, airplanes, and boats. Used as a solvent in paint and plastic industries. Also used to make polyester compounds. May be harmful by ingestion, inhalation, or through skin contact. Irritating to the eyes and skin.
Methylparabens and Propylparabens– Used as preservatives. Parabens are currently under scrutiny as they have been identified as estrogenic and disruptive of normal hormone functions; many studies are linking them with breast cancer tumors.
Polyethylene Glycol/PEG– Used as a thickener. Strips the skin’s natural moisture. A potentially harmful chemical, it can produce severe acidosis, central nervous system damage and congestion.
Glycerin– glycerin is a sugar alcohol compound. We don’t use it in our formulation because of concerns that it’s typically petrochemical based and additionally could increase the chances of getting yeast infections.
