Designed by the German company Evonik of Dr Straetmans, specialists in healthy natural conservatives for you and for the environment.

Natural preservative certified without synthetic and versatile preservatives, from sugar of the non -ripe juice of beet.

INCI : Pentylene Glycol

Appearance : Clear and odorless liquid, dermocaustic and irritating

Solubility: Water -soluble

Concentration: From 1% to 5%. The more your formula contains water, the more we suggest putting it in large quantities. However, you should not exceed 5%. We suggest putting less in formulas intended for facial care (more sensitive skin). Decrease the quantity if combined with another preservative.

Never apply pure to the skin.

Although this product is natural, it is very powerful. Conservatives manage bacteria and mold, they are often irritating in the pure or too large quantity. It is essential to comply with the recommended concentrations. You should also wear gloves and glasses when handling. Once integrated into a formula, no concerns to have.

pH: Youpi, this preservative works with any pH! If you calculate the pH of your product, it may change with the addition of this preservative. Do not panic, the pH will return to normal after about 2 hours.

Properties : Conservative, antimicrobial, moisture (unlike most conservatives, he is not drying, nor allergen elsewhere).

Use : For all your formulas containing an aqueous phase, including emulsions (E/H and H/E), formulas based on surfactants and aqueous formulas. Add at the end of the formulation and mix well.

Note that water without water do not require a curator. However, you will have the advantage of using an antioxidant, such as thevitamin E oil. It slows down fat, but is not a preservative.

The duration of the conversation : This is a whole challenge to provide the conservation time of a product! It depends on several factors, mainly on the aqueous bodies used and their proportion in the formula. On average, we plan a conservation of two years and more for surfactants based on surfactants (gels and liquid soaps), from a year and a half to two years for emulsions and aqueous formulas such as aqueous cosmetic serums and gels with stable aqueous phase. 

We recommend avoiding infusions and favoring aloe gel (which already contains a preservative), distilled water and hydrosols. According to the chemists, the latter are not stable, but we are herbalists, and we love the hydrosols! These can keep a good year or more. Which is rather stable for water. With hydrosols in the aqueous phase, an emulsion H/E is kept, thanks to the dermasoft Pentiol Eco, about two years. Wow!

ATTENTION : Hold out of the reach of children. /Do not swallow or inhale and avoid contact with the eyes. /Respect the recommended dosage. / Always do an allergy test on the forearm (finished product test).
