What parabens are, and why they're contested
Parabens are a family of preservatives - methylparaben, propylparaben, butylparaben, ethylparaben and a few others - that have been used in cosmetics since the 1920s. They are effective at very low concentrations, cheap, and stable across temperature ranges, which is why they remain legal in EU cosmetics under Regulation 1223/2009 at strictly limited percentages. The contested part is their weak estrogen-mimicking activity in laboratory studies. The European scientific consensus is that parabens at permitted levels are safe; the consumer concern is that the cumulative exposure from many products in a daily routine is hard to quantify. Many natural-cosmetics shoppers simply prefer to avoid the question. We are one of those shops.
What we use instead
Cold-process soap bars are essentially self-preserving: their high pH and low water content make them inhospitable to microbial growth. For our water-containing products - hydrosols, body splashes, creams - we rely on phenoxyethanol at well under 1%, potassium sorbate (the same preservative used in cheese and bread), and the inherent stability of cold-pressed oils stored away from light. The trade-off is a shorter shelf life than paraben-preserved cosmetics. Our products are typically dated to twelve to eighteen months from production. Store them out of direct sunlight, replace the cap firmly after each use, and the dates printed on the label are conservative.
