It is known to be less irritating than Sodium Lauryl Sulfate but can still strip natural oils from the hair and scalp. It is often criticized for potential contamination with 1,4-dioxane, a possible carcinogen.

It is generally considered safe but can cause allergic reactions in some individuals. It is often used in combination with other surfactants to improve the overall mildness of the formulation.

Dimethicone is a silicone-based polymer used for its smoothing and conditioning properties. It forms a barrier on the hair, which can lead to buildup over time, making hair feel heavy and potentially brittle. It is not water-soluble, which can make it difficult to remove without strong detergents.

Citric Acid is used to adjust the pH of cosmetic products, ensuring they are not too alkaline. It can also act as a mild preservative and antioxidant. It is generally safe but can cause irritation in high concentrations.

Hexylene Glycol is a solvent and viscosity agent used to improve the texture and spreadability of cosmetic products. It is generally considered safe in low concentrations but can cause irritation in sensitive individuals. It helps to dissolve other ingredients and improve the overall feel of the product.
