Overview
Prolong Spray is a clinically developed topical solution designed to temporarily reduce penile sensitivity, thereby extending sexual performance duration. As a B2B product, it is primarily supplied to adult wellness brands for private labeling or as a component in pleasure enhancement kits. The formulation typically contains mild anesthetics like lidocaine or benzocaine (3-5% concentration) combined with skin-conditioning agents. Unlike pharmaceutical-grade products, this consumer version balances efficacy with safety for occasional use. Most commercial variants are alcohol-free to prevent skin irritation.
Physical and Chemical Properties
The spray exhibits low viscosity (35-45 cP) for even application and quick absorption within 10-15 minutes. pH is balanced to 6.0-7.5 to match skin physiology. The base solution usually comprises purified water, glycerin, and mild surfactants. Key performance metrics include onset time (typically 10-20 minutes) and duration (1-2 hours). The formulation avoids oil-based components to prevent condom degradation. Most products incorporate cooling agents (menthol derivatives) for enhanced user experience without compromising the primary desensitizing effect.
Main Applications
Primary application is in sexual wellness products sold through e-commerce platforms, adult stores, and discreet pharmacies. Bulk purchasers often repackage the spray with custom branding for specific markets (e.g., luxury editions with aromatic additives). Increasingly incorporated into couple's intimacy kits alongside massage oils and sensual accessories. Some manufacturers blend the formulation with arousal-enhancing ingredients like L-arginine for dual-action products. The B2B market also supplies adult film production companies for talent preparation.
Safety and Storage
Manufacturers must comply with cosmetic or medical device regulations depending on jurisdiction (FDA OTC monograph in the US, CE marking in EU). Shelf life averages 24 months unopened when stored below 25°C. Critical safety considerations include clear labeling of active ingredients and contraindications (e.g., not for use with latex allergies if containing certain additives). Bulk shipments require temperature-controlled logistics if containing heat-sensitive compounds. Industrial packaging typically uses amber glass or HDPE bottles with child-resistant caps.
B2B Procurement Guide
Reputable suppliers provide third-party test reports for microbial content (<100 CFU/g) and heavy metals (meeting USP <232> standards). MOQs range from 500-5,000 units depending on customization level. Key procurement factors include: 1) Manufacturing certifications (GMP, ISO 13485 for medical device classification), 2) Flexibility in active ingredient concentration adjustments, 3) Packaging compatibility with automated filling lines. Sample evaluation should assess spray nozzle performance (0.1-0.3ml per pump) and residual leakage rates.
