Sodium laureth sulphate (SLES) is perhaps the most recognised compound within the broader sulphate family. Its widespread use stems from its ability to create rich lather and effectively emulsify oils, making it a staple in many cleansing products.
Sulphates are surfactants — molecules that reduce surface tension, allowing efficient mixing and impurity removal. Not a single ingredient, they are a diverse group with distinct chemical structures and functions.
The perception of sulphates as universally “bad” often originates from harsher early versions, which could strip hair of natural oils. Such older formulations sometimes led to dryness and scalp irritation.
Modern cosmetic chemistry has significantly advanced. Many formulations now utilise gentler sulphate derivatives — such as sodium coco sulphate or disodium laureth sulfosuccinate — maintaining cleansing efficacy without severe dehydrating effects.
The key lies in a formulation's overall balance — its pH level, conditioning agents, and specific surfactant type. A well-balanced product ensures effective cleansing while safeguarding hair’s integrity.
Most conventional shampoos rely heavily on aggressive sulphates for primary cleansing. Evera’s formulations, conversely, prioritise mild surfactants, often blending them with nourishing plant glycerides to mitigate potential dryness.
Our approach formulates for targeted efficacy; different hair types require varied cleansing levels. A robust cleanse benefits very oily scalps; dry or treated hair thrives with a gentler touch.
Consulting the INCI list — International Nomenclature of Cosmetic Ingredients — offers precise insight into a product’s composition. It allows differentiation between various sulphate compounds and other cleansing agents.
Ultimately, demonising an entire class of compounds overlooks the sophistication of contemporary cosmetic science. A discerning perspective on ingredients is always more valuable than broad generalisations.
