Contact time, frequency and what else is in the bottle decide whether it strips — and it is not the same molecule as sodium lauryl sulfate.","\u003Ch2>How it works\u003C\u002Fh2>\u003Cp>Sodium laureth sulfate is a fatty alcohol — usually of coconut or palm origin — that has had a short chain of ethylene oxide units attached and then a sulfate group placed on the end. The result is an anionic surfactant: a negatively charged head on a fat-soluble tail, the arrangement that lifts oil and debris off skin and hair and foams generously while doing it.\u003C\u002Fp>\u003Cp>Those inserted units are the whole difference between it and sodium lauryl sulfate. They make the head bulkier and hold water around it, so the molecule packs less tightly against the proteins of the outermost skin layer. Same class, same job, gentler contact — which is why two materials that behave differently get discussed as one. The number of units is not fixed either: laureth is a family, and a supplier's grade is a distribution rather than one molecule.\u003C\u002Fp>\u003Ch2>The evidence\u003C\u002Fh2>\u003Cp>That it cleans is not in dispute. What has been examined at length is irritation, and there the reliable finding is comparative rather than absolute: this is the milder of the two familiar sulfates, and how harsh a wash feels depends far more on the system than on this name. Contact time, frequency, water temperature and the secondary surfactants beside it move the result more than the sulfate does.\u003C\u002Fp>\u003Cp>The other question attached to it is 1,4-dioxane, a by-product that can form during ethoxylation. Nobody adds it; it is a trace that manufacturing is designed to strip out, and how much may remain in a finished cosmetic is set by each market and has been revised. That makes it a specification question for the supplier and the regulator rather than something readable from a label, and no number belongs on this page.\u003C\u002Fp>\u003Ch2>Suitability\u003C\u002Fh2>\u003Cul>\u003Cli>Fine for skin that gets on well with a foaming wash\u003C\u002Fli>\u003Cli>Dry, eczema-prone and reactive skin usually does better on a lower-foam system\u003C\u002Fli>\u003Cli>Short contact — apply, work, rinse — matters more than any percentage\u003C\u002Fli>\u003Cli>Common in face washes, body washes and shampoos, not in leave-on products\u003C\u002Fli>\u003C\u002Ful>\u003Ch2>Concentration\u003C\u002Fh2>\u003Cp>No figure, and one would mislead. The level follows the format and the rest of the blend; a mild co-surfactant changes the outcome more than a couple of points either way, and a rinse-off product's exposure is decided by contact time rather than concentration. Brands do not publish it and the ingredient list does not reveal it.\u003C\u002Fp>\u003Ch2>Conflicts & combinations\u003C\u002Fh2>\u003Cp>It cannot share a water phase with a cationic conditioning agent — opposite charges form an insoluble complex and both are wasted, which is why conditioning arrives as a separate step. The useful pairing is with an amphoteric or a sugar-based nonionic, and that is how most modern formulas soften it.

Они делают «голову» объёмнее и удерживают вокруг неё воду, поэтому молекула прилегает к белкам рогового слоя не так плотно. Тот же класс, та же работа, более мягкий контакт — оттого два разных по поведению вещества обсуждают как одно.

Время контакта, частота, температура воды и вторичные ПАВ рядом сдвигают результат больше, чем сам сульфат.\u003C\u002Fp>\u003Cp>Второй привязанный к нему вопрос — 1,4-диоксан, побочный продукт, который может образоваться при этоксилировании. Его никто не добавляет: это след, который производство удаляет, а сколько допустимо в готовой косметике, каждый рынок решает сам и пересматривает. Значит, это вопрос спецификации поставщика и регулятора, а не читаемый с этикетки, и никакой цифре здесь не место.\u003C\u002Fp>\u003Ch2>Кому подходит\u003C\u002Fh2>\u003Cul>\u003Cli>Годится коже, которая дружит с пенящимся умыванием\u003C\u002Fli>\u003Cli>Сухой, склонной к экземе и реактивной обычно лучше на менее пенной системе\u003C\u002Fli>\u003Cli>Короткий контакт — нанести, помассировать, смыть — важнее любого процента\u003C\u002Fli>\u003Cli>Обычен в умывалках, гелях для душа и шампунях, но не в несмываемом уходе\u003C\u002Fli>\u003C\u002Ful>\u003Ch2>Концентрация\u003C\u002Fh2>\u003Cp>Цифры нет, и она вводила бы в заблуждение.
