The　progress　in　the　study　on　complicated　reverse　aggregation　of　surfactants　in　non-polar　organic　solvents　is　reviewed.　Firstly,　the　problem　of　surfactant　dissolution　in　non-polar　organic　solvents(oils)　is　resolved.　The　inverted　aggregates　with　full　core-shell　structure　can　be　expected　to　form　using　synthesized　new　surfactants　with　a　large　headgroup　or　by　introducing　suitable　additives　to　interact　with　the　head　of　surfactant　and　increase　the　effective　size　of　the　head　of　surfactant.　These　steps　of　promoting　aggregate　formation　drive　the　surfactants　to　disperse　and　dissolve　in　non-polar　solvents.　Based　on　this　way,　a　one-step　method　of　directly　dissolving　and　preparing　homogeneous　solutions　of　surfactants　in　oils　is　developed　and　the　key　factors　about　this　method　are　discussed.　Comparatively,　the　direct　dissolution　method　is　more　convenient　and　also　more　effective　than　the　methanol　dissolution　method　as　reported　in　literature.　Some　typical　homogeneous　systems　of　surfactants　in　cyclohexane　are　exhibited　and　the　dissolution　method　upon　aggregate　formation　is　reviewed.　In　these　systems,　the　aggregates　show　varied　morphologies.　The　effect　of　surfactant　head　size　on　aggregate　morphology　is　also　discussed.　©　2019,　Editorial　Office　of　Progress　in　Chemistry.　All　right　reserved.
