Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
73 words
A fragrance dispersant composition for dispersing fragrance oil in an aqueous hard surface cleanser comprising a mixture of N(2-hydroxyethyl)acetamide comprising about 50 to about 80 weight percent of the fragrance dispersant composition, about 15% or more of an anionic surfactant capable of mixing with said N(2-hydroxyethyl) acetamide to form a homogeneous solution and an effective amount of fragrance oil, said anionic surfactant being present in an amount sufficient to solubilize said fragrance oil.
Claim 2
Dependent Claim
