Comparison: Sulfate Free No-Tear Shampoo Base vs. Standard Sulfate Free Shampoo Base
Question
Could you please explain the differences between the Sulfate Free No-Tear Shampoo Base (pH 6, Clear, Foaming) and the Sulfate Free Shampoo Base (pH 7, Clear, Foaming), particularly regarding the reason for the "no-tear" property and their respective cleaning power?
Answer
Understanding Sulfate Free Shampoo Bases
Regarding the Sulfate Free No-Tear Shampoo Base (pH 6, Clear, Foaming) and the Sulfate Free Shampoo Base (pH 7, Clear, Foaming):
Why is the No-Tear Base "No-Tear"?
The "no-tear" claim for the Sulfate Free No-Tear Shampoo Base is not solely due to its pH level. While a pH closer to that of tears (around 7.2-7.4) can contribute to reduced eye irritation, the primary reason for a product being "no-tear" lies in the specific blend of surfactants and other ingredients used in its formulation. The No-Tear base is formulated with very mild surfactants specifically chosen to minimize irritation if it comes into contact with the eyes.
Cleaning Power Comparison
When comparing the cleaning power of the two bases at the same concentration, the Sulfate Free No-Tear Shampoo Base generally has less cleaning efficiency than the Sulfate Free Shampoo Base (pH 7). This is a trade-off for its extra gentleness and "no-tear" property. User feedback also supports that the No-Tear version provides a milder cleanse compared to the standard type.
