4. REQUIREMENTS: Liquid hand soap furnished under this specification shall meet or exceed the following minimum requirements:

4.1. GENERAL REQUIREMENTS: The product as received shall be a clear, moderately viscous liquid at ordinary temperatures, and when cooled to 25 F (-3.9 C). when diluted with reasonably soft water in accordance with label instructions, it shall have a slippery feel and shall lather readily when rubbed between wet hands.

4.2. CHEMICAL REQUIREMENTS: The concentrate shall be manufactured by blending into a homogeneous solution in soft water the following ingredients, which shall comply with the cited Texas Specifications:

4.2.1. Coconut fatty acid (Texas Specification No. 180-48-10A) comprising at least 28.5 percent by weight of the total formulation.

4.2.2. Caustic potash, 45% solution (Texas Specification No. 180-58-01A) in sufficient amount to solubilize the fatty acid and adjust the final pH to the level specified in Requirement 4.3.3. this should require about 17.3 percent by weight of the total.

4.2.3. EDTA Tetrasodium salt amounting to 0.2 - 0.25 percent by weight of the total, or enough to ensure compliance with Requirement 4.3.5.

4.2.4. Colorants and fragrance materials sufficient to color and perfume the product in a pleasing manner selected by the manufacturer.

4.3. TEST REQUIREMENTS: The product shall conform to the requirements of Table 1, Test Requirements, when tested by the methods cited in Section 6.



Requirement Minimum Maximum Test
Matter volatile at 105 C, pbw* -- 66.00 6.10
pH as received 9.60 10.20 6.30
Sudsing ability - ml foam layer -- 150.00 6.40
Hard-water stability at 250 ppm CaCO3 -- pass 6.50
Free acid as lauric, pbw -- 1.00 6.60
Free alkali as KOH, pbw -- trace 6.60

*pbw (percent by weight)

5. SAMPLES: Unless otherwise specified in the Invitation for Bids, no prepurchase samples shall be required. Samples tested shall be taken from regular orders.

6. TESTING: Testing shall be done by or at the direction of, the Commission and/or the receiving State agency. Tests shall be performed on products from shipments to ordering agencies. In the event products tested fail to meet or exceed all conditions and requirements of this specification, the cost of the samples used and the cost of testing shall be borne by the supplier.

6.1. TESTS: The product furnished under this specification shall be tested by the following methods or approved equally applicable procedures:

6.1.1. Matter volatile at 105 C: Determine by the oven method of ASTM D 460, Paragraph 11.

6.1.2. Matter insoluble in alcohol: Determine by the procedure of ASTM D 460, Paragraphs 18 and 19, using as test sample the oven-dried residue from the previous test.

6.1.3. pH: Determine by the procedure of ASTM E 70.

6.1.4. Sudsing ability: Transfer a one (1) ml sample of concentrate by means of a volumetric pipette to a large beaker. Add 350ml distilled water, and mix on a magnetic stirrer. Fill a 250mil graduated cylinder up to the 50ml mark with the resulting 0.1% solution. Agitate the contents by rotating the stoppered cylinder smoothly about its midpoint to the inverted position and back again. After 20 inversions over a one (1) minute period, let stand for five (5) minutes, then read the net foam volume.

6.1.5. Hard-water stability: Prepare synthetic hard water containing 0.29g calcium chloride dehydrate and 0.13g magnesium sulfate heptahydrate per liter of solution in distilled water. Mix 20ml soap concentrate with 50ml hard water in a clear glass vessel, and examine for cloudiness. In order to pass Requirement 4.3.5. the solution must be perfectly clear.

6.1.6. Free acid or alkali: Determine by the procedure of ASTM D 460, Paragraphs 18 and 19, except that a fresh 10g sample of concentrate shall be used for the test. Titrate with either 0.1N KOH or 0.1N Hcl, depending on whether the sample solution is on the acid or alkaline side of the phenolphthalein end point. Determine the result, using whichever one of the following equations is applicable:

% lauric acid = ml titrant x normality x 20 / g sample

%KOH = ml titrant x normality x 5.61 / g sample

7. INSPECTION: Products furnished under this specification shall be inspected by, or at the direction of the Commission and/or the ordering State agency either at the destination or place of manufacture.

8. PACKING / PACKAGING: Packing for shipment shall be in accordance with the manufacturer's standard practice and in a manner readily accepted by common carriers engaged in interstate commerce. Within the shipping carton, units shall be packed in a manner designed to minimize damage during the shipment because of rough or improper handling.
