Ingredients higher up in an ingredient list are typically present in a larger amount. 1,2-Hexanediol is a synthetic liquid and another multi-functional powerhouse. It is a: Humectant, drawing moisture into the skin Emollient, helping to soften skin Solvent, dispersing and stabilizing formulas Preservative booster, enhancing the antimicrobial activity of other preservatives Benzoic Acid is an organic acid that shows up in cosmetics as a preservative. It helps keep a product from spoiling by holding back the growth of yeast, mold, and some bacteria. This ingredient also functions as a fragrance ingredient that helps mask the unpleasant scent of other ingredients. The way it works is worth understanding; benzoic acid works when the formula is acidic. It is able to sneak into a microbe's cell and mess up how it functions to stop it from growing in an acidic product. However, the acid switches to an inactive form and stops working if a product isn't acidic enough (above ~5 pH). This is why you'll often see it in low pH products or teamed up with other preservatives to cover the gap. Safety wise, it's one of the better studied preservatives out there. The Cosmetic Ingredient Review Expert Panel has concluded this ingredient to be safe for use in cosmetic formulations at concentrations up to 5%. A large international review found this ingredient had no effects on the human body and had low irritation potential. Just so you know, real world use is usually much lower than the 5% ceiling (usually 1% of less). The EU caps it at 2.5% in rinse-off products, 1.7% in oral care, and 0.5% in leave-on products. One thing worth mentioning (it's nothing to worry about): some people get a little stinging or flushing where they apply it. This isn't a true allergy; it's a temporary and harmless reaction. This is the same kind of mild tingle you might notice from sorbic acid. Biotinoyl Tripeptide-1 is a lab-made molecule that combines two parts: biotin (vitamin B7) and Tripeptide-1. Together, they form a peptide that’s often used in hair and eyelash products. In-vitro studies show this ingredient helps hair bulb cells grow faster and product more structual proteins. This helps keep hair securely anchored in the follicle. A small human study using a mascara with 2% Biotinoyl Tripeptide-1 reported lashes that were about 17% longer and 19% thicker after one month. One study from 2025 compared topical spray vs. a combined tropical/oral treatment. The combination group saw greater increases in total hair count. While these early results are encouraging, most of the data comes from in-vitro experiments (in test tubes) or small, short-term trials. Biotinoyl Tripeptide-1 looks promising for supporting hair strength and growth but there’s not yet strong clinical evidence to confirm how well it works. Butylene Glycol (or BG) is used within cosmetic products for a few different reasons: Overall, Butylene Glycol is a safe and well-round
