What is the Difference Between Sodium Lauryl Sulfate and Sodium Lauroyl Sarcosinate?

Sodium lauryl sulfate (SLS) and sodium lauroyl sarcosinate (SLS) are both surfactants, but they have different properties and effects on the skin and hair. Here are the main differences between the two:

1. Harshness: SLS is known to be harsh and irritating, while sodium lauroyl sarcosinate is mild and gentle. SLS can strip the natural moisture and color from the hair, causing dryness, frizz, and damage. In contrast, sodium lauroyl sarcosinate does not strip the natural moisture or damage the protective barrier of the skin.
2. Derivation: SLS is derived from petroleum, while sodium lauroyl sarcosinate is derived from natural sources such as coconut oil and sarcosine, an amino acid found in meat and eggs.
3. Environmental Impact: Sodium lauroyl sarcosinate is considered environmentally friendly and biodegradable, as it is derived from natural sources.
4. pH Balance: Sodium lauroyl sarcosinate is gentle on the hair and scalp and does not affect the skin's natural pH balance.
5. Appearance and Feel: Sodium lauroyl sarcosinate enhances the appearance and feel of the hair by improving the body, suppleness, and shine.

In summary, sodium lauroyl sarcosinate is a milder and more gentle surfactant compared to sodium lauryl sulfate, making it a better choice for most skin types and hair types.

Comparative Table: Sodium Lauryl Sulfate vs Sodium Lauroyl Sarcosinate

Sodium lauryl sulfate (SLS) and sodium lauroyl sarcosinate are both surfactants used in various cleaning products and toiletries. However, they have some differences in their properties and effects on the skin and hair. Here is a comparison table between the two:

Sodium lauroyl sarcosinate is considered a milder and more gentle alternative to sodium lauryl sulfate, making it suitable for use in products like baby shampoos and other personal care items.
