evidence: Mumbai, July 6: A viral claim circulating on social media suggests that the coloured marks at the bottom of toothpaste tubes indicate whether the ingredients are natural or chemical-based. According to the claim, black signifies pure chemicals, red denotes a mix of natural and chemical ingredients, blue indicates a blend of natural substances with medicinal properties, and green suggests purely natural ingredients. However, this assertion is misleading and lacks factual basis. [...] Pacmac, a company specialising in tube filling machines, clarified that these marks help machines detect the tube's end, ensuring precise packaging and printing alignment. Different colours signify various sensors or stages in the packaging process and are not related to the toothpaste's ingredients. Furthermore, toothpaste ingredient information crucial for consumers is typically found on the product packaging itself or on the tube.

Basic components such as abrasives for cleaning, humectants for texture, fluoride for dental protection, and flavouring agents are standard across all toothpaste varieties. Despite claims suggesting colour-coded insights into ingredient purity, no toothpaste brands in India or elsewhere can claim to be entirely natural, as confirmed by the Department of Consumer Affairs. In conclusion, the notion that toothpaste tube colour codes provide insights into ingredient composition is erroneous. Consumers should rely on printed ingredient lists and regulatory guidelines for accurate information about the products they use. Misinterpretations like these underscore the importance of verifying information before sharing it widely on social media platforms.
