What if everyone switched for good to brands that have mastered natural preservation?<\/p>\n
All cosmetic products on the market are guaranteed to be \u201cstable\u201d for a certain period. But often at the cost of cocktails of chemical preservatives. Some of them are criticized as probable endocrine disruptors (the well-known parabens, among others)\u2026 At PHYT\u2019S, we work to develop formulas for cosmetics without synthetic preservatives<\/strong> that keep naturally. It is a complex exercise that we master well, thanks in particular to our expertise in working with essential oils.<\/p>\n To find out whether a cosmetic product keeps<\/strong> well, every laboratory must have \u201cchallenge tests\u201d carried out. In these tests, the cream being tested is inoculated with germs (yeasts, moulds, bacteria\u2026) following very strict protocols. Then we observe whether the product resists the growth of these germs. At PHYT\u2019S, (organic!) essential oils really are our \u201cfavourites\u201d. First, because they have countless qualities that make our cosmetics \u201cactive\u201d and effective. Second, because they give our products their subtle, distinctive fragrances. And finally, because these plant concentrates help preserve our formulas. When PHYT\u2019S began, the brand only offered \u201csalon treatments\u201d in glass ampoules: single doses that were practical and guaranteed preservation for the esthetician. Then products \u201cfor retail\u201d were developed, this time in metal tubes, but they tended to bend and get damaged. Finally, from the 1990s, we chose an innovative packaging that is both flexible and rigid, and very airtight: the multilayer Polyfoil tube. The goal: protect the cream from the outside environment. And it worked, since all our cosmetics keep without any problem, with an expiry date set at 3 years.<\/p>\n","protected":false},"excerpt":{"rendered":" What if everyone switched for good to brands that have mastered natural preservation?

\nThis makes it possible to check that the ingredients used, for example in the cream, oil or shower gel, keep the formula stable. In organic cosmetics, the list of authorized synthetic preservatives is extremely limited (restricted to a few substances considered \u201clight\u201d). Cosmetics manufacturers must therefore use ingredients of natural origin with \u201cpreservative\u201d properties. This is the case for certain essential oils that we know well at PHYT\u2019S. For more than 40 years, the laboratory has chosen \u201c0% chemical synthesis\u201d. It also strives not to \u201cuse up\u201d the famous 5% of synthetic preservatives allowed by the Cosmebio charter. This approach is rare, because designing hygiene and skincare products without synthetic preservatives is a difficult craft. It requires real knowledge of plant actives.<\/p>\nEssential oils, amazing natural preservatives<\/strong><\/h2>\n
\nThis is the case for certain essences, such as fine lavender or common thyme, which have powerful bactericidal and bacteriostatic properties. But be careful! Using essential oils in cosmetics requires precise know-how. Optimizing both the preservation effectiveness AND the skin tolerance of essential oils is a real art\u2026
\nIn addition, advances in scientific research have helped us discover other natural ingredients that help with preservation, such as certain natural fragrances.<\/p>\n\u201cPolyfoil\u201d tubes: airtight packaging that keeps cosmetics naturally<\/strong><\/h2>\n
