Nanoemulsion and Moisturizing Cleansing Composition Comprising the Same

An oil-in-water nanoemulsion comprising:

• a) from 1.5 to 8.5% by weight anionic surfactant, the anionic surfactant comprising 100% by weight acyl isethionate or 100% by weight acyl taurate based on total weight of the anionic surfactant, or acyl isethionate, acyl taurate or both and co-anionic surfactant, the co-anionic surfactant making up from 0.01 to 65% by weight of the total weight of anionic surfactant in the nanoemulsion, the co-anionic surfactant not being an acyl isethionate or acyl taurate;
• b) from 0.0 to 5.5% by weight amphoteric surfactant;
• c) from 0.2 to 5.5% of a C8-C18, and preferably, C10-C16, and most preferably, C12-C14 fatty acid, fatty alcohol, fatty amide, or a mixture thereof;
• d) from 40 to 70% by weight of a mixture of non-hydrogenated oil and hydrogenated oil, the mixture comprising no more than 37% by weight hydrogenated oil based on total weight of the mixture of non-hydrogenated and hydrogenated oil;
• e) from 13 to 55% by weight water,
• with the provisos that the nanoemulsion:
• i) has a pH from 5.3 to 7.5, and preferably, from 6 to 7, and most preferably, from 6.1 to 6.9, or from 6.1 to 6.8;
• ii) is substantially free of at least one of sulfate-based surfactants, phthalates, dioxanes, parabens, hydantoins and isothiazolinones;
• iii) has total surfactant that does not exceed 11.5% by weight of the nanoemulsion;
• iv) has the oil at a droplet size from 10 to 775 nm;
• v) comprises from 42 to 75% by weight oil.
