Formulation Deep Dive

RapidLash’s RapidBrow® Eyebrow Enhancing Serum is formulated as a high-performance aqueous-based brow treatment designed to stimulate and fortify the hair follicle. The carrier system utilizes a blend of water and butylene glycol for efficient active delivery, while hydroxyethylcellulose and rhizobian gum provide the necessary viscosity for targeted application. The formulation’s performance is driven by a synergistic Hexatein® 2 Complex, featuring Biotin (Vitamin B7), Panthenol (Pro-vitamin B5), and a peptide-rich profile including Octapeptide-2 and Copper Tripeptide-1 to support keratin production and hair anchoring. Botanical support is provided by Malus Domestica (Apple) Fruit Cell Culture Extract and Cucurbita Pepo (Pumpkin) Seed Extract to improve the appearance of brow density. The system is stabilized with a polymer network of Styrene/Acrylates/Ammonium Methacrylate Copolymer and PVP, utilizing a robust preservative blend of phenoxyethanol, chlorphenesin, and sorbic acid to ensure long-term formula integrity.

Preservative
Potassium Sorbate GOOD
Functions as a preservative (antimicrobial), protecting water-containing formulations primarily against yeasts and molds, with weaker activity against bacteria. Its activity is pH-dependent and strongest in acidic systems (effective below roughly pH 6, optimal near pH 4.4), so it is used in low-pH products and is commonly paired with a second preservative such as sodium benzoate for broad-spectrum coverage.
Preservative
Sodium Hydroxide GOOD
A strong alkali used at trace levels as a pH adjuster — to neutralize acids, set a formula’s target pH and activate gelling agents such as carbomer.
Disodium Phosphate NOT RATED

A mild, nonionic oil-in-water emulsifier and solubilizer that binds oil and water into stable emulsions and disperses fragrance and oil-soluble actives into water-based formulas.
Emulsifier Solvent
Sodium Phosphate NOT RATED
Citric Acid GOOD
Acts mainly as a pH adjuster and buffer and as a chelating agent that protects formula stability and preservation; at higher leave-on levels it also serves as a mild exfoliating AHA.

Polyaminopropyl Biguanide NOT RATED
Backhousia Citriodora (Australian Lemon Myrtle) Leaf Oil NOT RATED
Sodium Laureth Sulfate NOT RATED
C11-15 Pareth-7 NOT RATED
Sodium Benzoate GOOD
Functions as a preservative (antimicrobial), protecting water-containing formulations from yeast, mold, and bacterial spoilage. Its activity is pH-dependent and strongest in acidic systems (optimal below roughly pH 5), so it is used in low-pH products and frequently paired with potassium sorbate for broader, more robust preservation.
