- surfactant mildness can be measured by a skin barrier destruction test which is used to assess the irri- tancy potential of surfactants. In this test the milder the surfactant, the less the skin barrier is destroyed. Skin barrier destruction is measured by the relative amount of radio-labelec water (3H-H 0) which passes from the test solution through the skin epidermis into the physiological buffer contained in the diffusate chamber. This test is described by T. J. Franz in the J. Invest. Dermatol., 1975, 64, pp. 190-195; in U.S. Pat. No. 4,673,525, Small et al., issued June 16, 1987, and in copending U.S. Pat. Application Ser.

- water-soluble alkaline earth metal salt such as magnesium sulfate or chloride, or calcium chloride
- the magnesium soap is made before the synthetic surfactant is added to the mix. Mixing is then continued to insure the equilibrium in the formation of the magnesium soap is attained. Desirable adjustments in water- soluble soap content may, of course, be made after the magnesium soap has been formed.
- the crutcher mix is dried and cooled using a combination flash chamber and chill roll or chill belt.
- the crutcher mix is first heated to approximately 132'C (270'F) by a heat exchanger and then flash dried in a chamber above the chill roll or chill belt. From the flash chamber the hot, dried mix is extruded onto the chill roll or chill belt.
- the chill belt or chill roll provides a uniform, thin, cool (29-35'C, 85-95'F) product in flake or chip form. Typical moisture for the flake is 2-12%, preferably 6-8%.
- the ways to regulate the moisture, in the order of prefer ⁇ ence are (1) increasing or decreasing steam pressure on the heat exchanger; (2) increasing or decreasing crutcher mix rate to the heat exchanger; and (3) increasing or decreasing crutcher mix temperature to the heat exchanger.
- the flakes are weighed and mixed in a batch amalgamator to obtain uniform flake size. Preweighed perfume is added to the flakes and mixed in the amalgamator to obtain the desired finished product perfume level. The perfumed flakes are transferred to the mill hopper or directly to the plodder. Milling (Optional)
- the 3-roll soap mills are set up with the first roll at 38°C (100'F) and the other two mills at about 21'C (70'F).
- the soap is passed through the mills several times to provide a homogeneous mixture of perfume and dried flakes.
- the plodder is set up with the barrel temperature at about 21'C (70"F) and the nose temperature at 38-49'C (100-120'F).
- the ideal plodder is a dual stage plodder that allows use of a vacuum of about 15-25 inches of Hg.
- the plugs should be cut in 5" sections and stamped with a cold die block using die liquor such as alcohol, if appropriate.
- the mild personal cleansing bars of Examples 1-7 are made using the above preferred crutching neutralization process.
- Example 8 is made by adding magnesium chloride to Na soap to for- ⁇ the Mg soap by ion exchange before mixing with the synthetic surfactants. Comparative Example A is made similar to the bars of
- Mg(0H)2 is used as a standard for the mildness and smears.
- Comparative Example B is the "B" bar and is used as a second standard for the mildness and smears.
- Comparative Example C is a leading commercial all soap bar and is used as a standard for typical all soap bars.
- Example 3 is the preferred overall bar for mildness, lather, and smears.
- All series of testing should include control, and all samples should be run in duplicates. A maximum of 7 products (6 plus a control) can be tested at one time, and an interval of 10 minutes between every 4 samples should be allotted for the addition of water as to not allow any products a lag time for soaking longer than 2 hours.
- Alathon soap dishes Small measuring cylinder Method 1. Wet soap bar to be tested by dipping surface to be soaked in distilled water and shaking off excess water. This procedure leads to more uniform bar smear. 2. Place bar centrally on "-Alathon” dish containing 5 ml of distilled water. Rock dish to break water tension. The Alathon dish was selected as being a standard, readily available (in U.S.) dish with low ridges. 3. Store overnight (approximately 18 hours) in standard con ⁇ ditions of temperature and humidity (27'C/80'F/80% RH were used). As this test measures the bar's ability to recover as well as absorb water, standard conditions avoid seasonal variations which may occur in uncontrolled laboratory over- night conditions.
- Ecze atous change may be present. Powderiness may be present but not prominent. May see bleeding crack.
- magnesium soap some or all of the magnesium soap can be replaced with other alkaline earth metal soap such as calcium, zinc, aluminum, and other soaps, which are substantially insoluble on the order of magnesium soap.
- Emersol 132 (Emery Industries) is really a mixture of stearate and laurate having a titer of about 55 and a maximum I.V. of 0.5. . x. Ex. 3 Ex. 4
- lathering mild synthetic surfactant mag- nesium soap
- non-soil-load non-lathering surfactant
- soil load diluent for Examples 1-4 are as follows:
- Example 7 The total level of synthetic surfactants in Example 7 is 56%, and the water level is 7.5%; the ratio of Mg soap to total synthetic is 0.18:1.
- the smears could be improved in Example 7 by lowering the water level to below about 7%.
- Example 5 which has a total synthetic of 56.6% and a Mg soap to total synthetic ratio of 0.22:1 but has a higher Mg soap level, 12.8% vs. 10%, has a better smear, notwithstanding equal water levels for Examples 5 and 7.
- mag ⁇ nesium soap level when the mag ⁇ nesium soap level is low, e.g., 10% or less, and when the level of the total synthetic surfactant(s) to magnesium soap is more than 5:1, the water level of the bar should be from about 2% to about 7%, preferably from about 2.5% to about 6% for improved smear.
- Comparative Example A is an ultra mild bar having fairly good smear, about the same as the "B" bar, a mild, commercially avail ⁇ able, soap/synthetic bar. Comparable mild bars of this invention, e.g., Examples 1-6 and 8 have improved smears over Example A, as well as the Standard Comparative Example B, which is the "B" bar. Comparative Example C is a leading pure soap bar to show the superior mildness of the bars of this invention over it.
- Comparative bar Example C a leading all soap bar, has the highest erythema grad of 2.42.
- Examples 4, 3, and 7 have erythema grades comparable t the "B" bar which show grades of from about 0.65 to about 1.29, the low and the high of four "B" bar grades.
- the erythema grade for 4, 3, and 7 are, respectively, 1.18; 0.90; and 0.68.
- Th erythema grades for Example 8 and Comparative Example A are bette than the all soap bar, Example C, and are close to the "B" bar.
- Example 8 has less preferred fatty matter, specifically a lower titer (37) and a higher Iodine Value (38) than Examples 4, 3, and 7.
- the titers and I.V.'s for Examples 4, 3, 7, and 8 are:
- Example 8 has an excellent Smear 2 of 8.
- Example 2 Significance at 90-95% confidence. Forearm Clinical results suggest that Examples 8, 9, and 2 are all better than "B" for both Redness and Dryness. Examples 8 and A are about equal, and A is significantly better than B. Example 2 is also significantly better than “B.” . Example 2 also has superior smears over “B” as shown in Tables 1 and 2; Average Smears 1 are 0.98 for Example 2 vs. 2.55 for "B,” which shows a significant advantage for Example 2. Smears 2 are 7.5 for Example 2 vs. 7.0 for "B,” which is a slight advantage for Example 2. A panel of experts compared some sensory characteristics of Example 2 with those of the "B” bar. The results are: Example 2 has sensory characteristics, tightness, smoothness, and softness, comparable to the "B” bar. The tightness result is surprising in view of the presence of 33% magnesium soap in Example 2.
