混じりけ is a similar noun meaning mixture or impurity, but 混じりっけ is a more colloquial or emphatic variant with the same meaning.
Derived from the verb 混じる (まじる, to mix) with the suffix っけ, which adds a sense of 'something mixed in' or 'impurity'. The exact derivation of っけ is uncertain, but it may be related to the noun-forming suffix 気 (け).
