    摘要: 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 (170-205° F; 76-96°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; III) cooling said mixture to a semi-solid in a scraped wall heat exchanger freezer; II) 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.
