"The lubricant bought has darkened in color after only a few uses. Is it still safe to use?" Consumers often have such doubts. As a product frequently applied to sensitive areas, water based lubricant can pose serious infection risks if it deteriorates and bacteria grow inside. For both brands and consumers, knowing how to identify spoilage is crucial for protecting brand reputation and personal health.
The most direct way to identify spoilage is by "smelling, looking, and touching." A normal lubricant should not have a pungent or sour odor; if the smell changes, it is likely due to microbial overgrowth. Observe the texture. If the product shows obvious layering, flocculent substances, or the color changes from clear to cloudy, it indicates that the preservative system has failed or the formulation stability is compromised. Finally, touch it. Spoiled lubricant often loses its original silky feel, becoming unusually sticky or developing granular crystals. This is usually caused by substandard production environments or the use of non-medical-grade raw materials leading to chemical reactions.
To avoid deterioration issues, brands should choose factories with GMP pharmaceutical-grade standards from the early stages of outsourcing. Truly compliant factories use 100,000-class cleanrooms to isolate contamination sources and employ vacuum packaging or anti-backflow pump head designs. This extreme investment in production processes ensures consistent product quality throughout the shelf life. Selecting factories with 21 quality inspection steps and adherence to international certification standards (such as FDA, CE) is the fundamental guarantee to prevent deterioration problems and improve brand repurchase rates.
