sindets

Sindets is a term with limited and scattered usage, and there is no widely accepted definition in major reference works. In many contexts, it is a misspelling or variant spelling of syndet, the term commonly used to describe synthetic detergents or cleansing surfactants. When linked to this sense, sindets refer to the class of surfactants designed to cleanse without the high alkalinity and drying effects associated with traditional soaps.

In the context of cleansing products, syndets are formulated to have a mild pH closer to that of human skin, which can reduce irritation for sensitive users. They are widely used in shampoos, facial cleansers, and body washes. Common ingredients found in syndet formulations include sodium cocoyl isethionate, sodium lauryl sulfoacetate, alkyl polyglucosides, and cocoamidopropyl betaine. Compared with traditional soaps, syndets tend to produce less soap scum, be gentler on the skin, and offer a broader range of viscosity and foaming properties, depending on the formulation.

Outside of the cleansing context, sindets may appear as a proper noun in specific works, names, or niche discussions, but there is no established, general meaning for the term beyond its possible association with syndets.

Etymology for the term sindets is unclear, and usage appears to be inconsistent. When encountered, it is often safest to treat it as a probable misspelling or as a context-specific label rather than a standalone technical term.
