No skin type needs it.","It is there for feel rather than for skin. The soft finish after rinsing is deposition, not repair.","\u003Ch2>How it works\u003C\u002Fh2>\u003Cp>Polyquaternium-7 is a synthetic copolymer of acrylamide and a small quaternary ammonium monomer, which gives one long chain carrying many fixed positive charges. Skin and hair surfaces are net negative at ordinary pH, so the polymer is drawn to them, and because it makes so many points of contact along its length it does not come away easily when the water arrives.\u003C\u002Fp>\u003Cp>That is the whole mechanism, and it is the clearest everyday demonstration of substantivity: a product that is rinsed away deliberately leaving something behind. What stays is a thin, flexible film that lowers friction, so hair detangles and skin feels smooth and slightly coated rather than squeaky. It also softens the surfactants it travels with, which is a second reason it is in the bottle.\u003C\u002Fp>\u003Ch2>The evidence\u003C\u002Fh2>\u003Cp>The deposition is real, measurable and the reason the material exists. What it is evidence of needs care. A smooth after-feel is a change to the surface, not to the barrier: nothing has been repaired, no lipid replaced, no water content raised beyond what a film slows down. A cleanser that leaves skin feeling looked after may be doing exactly that and no more, which is fine until it is credited with more.\u003C\u002Fp>\u003Cp>The manufacturing question worth knowing is residual monomer. Acrylamide is a monomer of concern, and a polymer built from it is supplied against a specification limiting how much unreacted monomer may remain. That limit is set by each market and revised, so the current local rule is the reference. It is a supplier and regulator matter rather than something a label reveals, and no figure is quoted here.\u003C\u002Fp>\u003Ch2>Suitability\u003C\u002Fh2>\u003Cul>\u003Cli>No skin type needs it; it changes how a wash feels rather than what it does\u003C\u002Fli>\u003Cli>Anyone who wants a squeaky finish will not want it\u003C\u002Fli>\u003Cli>Skin that finds cleansers tightening often prefers products that carry it\u003C\u002Fli>\u003Cli>Found in body washes, facial cleansers, micellar waters and shampoos\u003C\u002Fli>\u003C\u002Ful>\u003Ch2>Concentration\u003C\u002Fh2>\u003Cp>Used at a low level and not disclosed. Polymers of this kind work at fractions of a percent, which also places them below the point at which an ingredient list has to keep its order, so the position of the name says nothing about the amount. What can be judged is the result: if a wash leaves skin feeling coated, something is depositing.\u003C\u002Fp>\u003Ch2>Conflicts & combinations\u003C\u002Fh2>\u003Cp>Being cationic it is the classic partner for an anionic cleansing system — but as a designed pairing, since the two charges can also form an insoluble complex when the ratio is wrong. That is a formulation problem rather than a routine one. On skin there is nothing to schedule around it; on hair the film is cumulative over repeated washes and comes off with a stronger, more anionic wash, which is what a clarifying step is for.\u003C\u002Fp>","Polyquaternium-7: the cationic polymer that deposits from a rinse-off wash, why a smooth after-feel is a film rather than repair, and where the residual monomer question sits.",{"faq":75,"tldr":91,"title":95,"content":96,"meta_description":97},[76,79,82,85,88],{"a":77,"q":78},"Несёт по длинной цепи закреплённые положительные заряды, поэтому связывается с отрицательно заряженной поверхностью кожи и волоса и остаётся после смывания.

Мягкость после смывания — это осаждение, а не восстановление.","Поликватерниум-7","\u003Ch2>Как это работает\u003C\u002Fh2>\u003Cp>Поликватерниум-7 — синтетический сополимер акриламида и небольшого четвертичного аммониевого мономера; получается одна длинная цепь с множеством закреплённых положительных зарядов. Поверхность кожи и волоса при обычном pH заряжена суммарно отрицательно, поэтому полимер к ней тянется, а поскольку по своей длине он касается её во множестве точек, вода уносит его с трудом.\u003C\u002Fp>\u003Cp>Это весь механизм — и самое наглядное бытовое подтверждение субстантивности: средство смывают, а оно намеренно оставляет что-то после себя. Остаётся тонкая гибкая плёнка, снижающая трение: волосы легче расчёсываются, а кожа ощущается гладкой и слегка укрытой, а не скрипучей. Заодно он смягчает ПАВ из того же флакона — вторая причина его присутствия.\u003C\u002Fp>\u003Ch2>Доказательная база\u003C\u002Fh2>\u003Cp>Осаждение реально, измеримо и составляет смысл существования материала. Осторожность нужна с тем, доказательством чего оно служит. Гладкость после — изменение поверхности, а не барьера: ничего не восстановлено, липиды не заменены, содержание воды не поднято сверх того, что задерживает плёнка. Умывалка, после которой кожа чувствует себя ухоженной, может делать ровно это и ничего больше — что нормально, пока ей не приписали большего.\u003C\u002Fp>\u003Cp>Производственный вопрос, который стоит знать, — остаточный мономер. Акриламид — мономер, вызывающий озабоченность, и полимер на его основе поставляют по спецификации, ограничивающей, сколько непрореагировавшего мономера может остаться. Этот предел каждый рынок устанавливает и пересматривает сам, так что ориентир — действующее местное правило. Это дело поставщика и регулятора, а не то, что видно на этикетке, и цифр здесь не приводится.\u003C\u002Fp>\u003Ch2>Кому подходит\u003C\u002Fh2>\u003Cul>\u003Cli>Ни одному типу кожи он не нужен: он меняет ощущение от умывания, а не его действие\u003C\u002Fli>\u003Cli>Тем, кто хочет «скрипучей» чистоты, он не понравится\u003C\u002Fli>\u003Cli>Коже, которую умывание стягивает, средства с ним часто приятнее\u003C\u002Fli>\u003Cli>Встречается в гелях для душа, умывалках, мицеллярных водах и шампунях\u003C\u002Fli>\u003C\u002Ful>\u003Ch2>Концентрация\u003C\u002Fh2>\u003Cp>Используется в малом количестве и не раскрывается.
