Noticing thinned shampoo with odd smell; possibly expired or altered batches received.
Experiencing thinned consistency and chemical odor in recent shampoo orders, suspecting expired stock or potential tampering affecting product integrity.
This is a review from Amazon.com about product:
Keratherapy Keratin Infused Moisture Shampoo, 10.1 fl. oz., 300 ml - Anti Frizz Moisture Shampoo for Oily Scalp and Dry Ends - Kerabond Technology, Aloe Vera, & Willow Bark
The last 2 shipments I received shampoo that was thinned out and had a weird chemical smell to them. Either they are very old batches that have been sitting on a shelf for a while or they have been tampered with.
Shampoo Basics & Tips
Understanding Shampoo Consistency and Odor Changes
Thinned Formulation: Shampoo viscosity changes could indicate ingredient separation due to prolonged storage. Most formulas contain stabilizers that degrade over 2-3 years, potentially altering texture.
Chemical Smell Development
Shelf Life Factors: Preservatives like parabens break down over time, releasing volatile compounds. Temperature fluctuations during storage accelerate this process, creating unusual odors.
Batch Age Indicators
Production Codes: Manufacturers use Julian date coding (e.g., 22435 = 2022 day 435). Older batches exceeding 36 months may show quality degradation.
Tampering Evidence
Packaging Integrity: Legitimate shrinkage occurs naturally, but sudden viscosity changes combined with broken seals suggest possible dilution or contamination during handling.
Quality Preservation
Storage Conditions: Ideal shampoo preservation requires stable temperatures (15-25°C) and humidity below 60%. Improper storage accelerates ingredient breakdown.
