  • Patent number: 5225098
    Abstract: The invention provides a firm, ultra mild, neutral pH freezer bar comprising: from about 10% to about 50% of monocarboxylic acid; wherein from about 20% to about 65% by weight of said monocarboxylic acid is neutralized; from about 20% to about 65% of an anionic and/or nonionic bar firmness aid, and from about 15% to about 40% water by weight of said bar;wherein said neutral pH is from about 6.3 to about 8.0;wherein the neutral pH freezer bar is made by the following steps:I. mixing a molten (170.degree.-205.degree. F.; 76.degree.-96.degree. C.) mixture comprising said carboxylic acid; water; and bar firmness aid; neutralizing said 20% to about 65% of said carboxylic acid, preferably with sodium hydroxide;II. cooling said mixture to a semi-solid in a scraped wall heat exchanger freezer;III. extruding said semi-solid as a soft plug; and further cooling and crystallizing said soft plug until firm to provide said neutral pH personal cleansing freezer bar.
