Hola, estoy de viaje y hoy me he fijado que el compuesto de plantas micronizadas de la marca RHATMA, que sirve tanto de desodorante como para evitar la humedad y aliviar algunas irritaciones, tiene otros ingredientes, entre los cuales, magnesium stearate; sabeis si puede ser vegetal? Ahora no lo tengo a mano porque se lo he prestado a una amiga a la que le ha picado una avispa y le va muy bién, pero tenia ingredientes tipo zinc o oxido de zinc, aparte de las plantas.

Magnesium stearate, also called octadecanoic acid, magnesium salt, is a white substance which is solid at room temperature. It has the chemical formula Mg(C18H35O2)2. It is a salt containing two equivalents of stearate (the anion of stearic acid) and one magnesium cation (Mg2+). Magnesium stearate melts at about 88 °C, is not soluble in water, and is generally considered safe for human consumption. Because it is widely regarded as harmless, it is often used as a diluent[1] in the manufacture of medical tablets, capsules and powders.[2] In this regard, the substance is also useful because it has lubricating properties, preventing ingredients from sticking to manufacturing equipment during the compression of chemical powders into solid tablets; magnesium stearate is the most commonly used lubricant for tablets.[3] It is used to bind sugar in hard candies. It is also a common ingredient in baby formulas. In pure powder form, the substance can be a dust explosion hazard,[4] although this issue is effectively insignificant beyond the manufacturing plants using it.

When used as a filling agent in the manufacture of capsules and tablets, such as vitamins, the source of this ingredient is typically bovine.[citation needed] However, there is an increasing number of vegetarian options in which the product specifically indicates it contains magnesium stearate from vegetable sources.

Magnesium stearate is a major component of "bathtub rings". When produced by soap and hard water, magnesium stearate and calcium stearate both form a white solid insoluble in water, and are collectively known as "soap scum".

Gracias Zen. Sabia que todo lo que son esteres, acido estearico, etc, es muy probable que sean grasas animales pero que también hay de vegetales. Por eso he hecho constar la marca, por si también hay alguien que la conozca y sabe algo. En la dietética me dijeron que todos los ingredientes eran vegetales, pero tampoco seria la primera vez que les pillo que les pillo con algun ingrediente que no sabian qué era.
