| Performance Data |
| Physical property and
performance data for a variety of nonionic surfactants are shown
in the following figures and tables. HOLOF
LF-03 Surfactant is water soluble, has a cloud point
of 50 °C, and is compared to commercially available products
with similar properties. The products used in these tests are
described below: |
| |
PAE- |
A primary alcohol ethoxylate
with a 9-11 carbon chain length hydrophobe, approximately 6
moles of ethylene oxide in the hydrophile, and a cloud point
of 52 °C. (Product tested: Shell NEODOLR 91-6). |
| |
NPE |
A nonylphenol ethoxylate
with approximately 9 moles of ethylene oxide in the hydrophile
and a cloud point of 54 °C.
(Product tested: Union Carbide TERGITOLR NP-9 Surfactant). |
| |
| Low Odor |
| One of the most important
benefits of narrow range alkoxylation technology is a low level
of unreacted alcohol, which is in part responsible for the low
odor of HOLOF LF-03 Surfactant.
In many applications, a high level of unreacted alcohol results
in reduced performance because the unreacted alcohol is an inactive
species. Typical unreacted alcohol contents for HOLOF
LF-03 Surfactant and the competitive surfactant are shown
in Table 1. HOLOF LF-03 Surfactant
has a lower level of unreacted alcohol than other primary alcohol-
based surfactants. |

| Handling |
| HOLOF
LF-03 Surfactant has a uniquely low pour point, resulting
in excellent cold weather handling characteristics. Competitive
surfactants with higher pour points often require preheating
in hot rooms or with drum heaters, adding both cost and processing
time to operations. Table 2 compares the pour point of HOLOF
LF-03 Surfactant with competitive surfactants. |

| Aqueous Viscosity |
When formulating products with high
levels of nonionic surfactant, hydrotropes or solvents must
often be added to reduce viscosity and/or prevent gelling. Figure
1 shows the viscosity profile of HOLOF
LF-03 Surfactant and the competitive surfactants graphically,
while Table 2
gives the same data numerically. |
| HOLOF
LF-03 Surfactant builds viscosity at a very slow rate
and does not have a gel range, as does the NPE. Thus, HOLOF
LF-03 Surfactant can often be formulated into concentrated
products with a minimal amount of hydrotrope or solvent, thereby
reducing the final cost of the formulation. |

| Gel Temperature |
One of the key characteristics
of concentrated surfactant solutions is gel temperature. Gel
temperature is defined as the temperature at which a solution
changes from a homogeneous liquid to a non-pourable gel upon
cooling, and it provides a measure of how well a concentrated
surfactant solution will dissolve in cold water. Table 4 shows
gel temperatures for HOLOF LF-03 Surfactant
and the competitive surfactants. The two competitive products
are well known for their attractive solution properties. This
characteristic is verified by the gel temperature data. Only
50- and 60- percent solutions of HOLOF
LF-03 Surfactant have a measurable gel temperature and,
in these cases, it is below ambient temperature. The gel temperature
profile indicates that HOLOF LF-03 Surfactant
will provide outstanding cold- temperature handling and dissolution
properties. |

| Surface Tension
Reduction |
| Perhaps the most universally
recognized performance characteristic of a surfactant is its
ability to reduce the surface tension of water. Figure 2 illustrates
the dependence of aqueous surface tension on surfactant concentration
for HOLOF LF-03 Surfactant. Surface
tension decreases rapidly with increasing surfactant concentration
until the critical micelle concentration (cmc) is attained at
0.0181 wt . Above the cmc, surface tension remains relatively
constant at approximately 28 dynes/cm and the average area per
molecule at the air/water interface, calculated from the Gibbs
Equation, is 58 square Angstroms. The low cmc of HOLOF
LF-03 Surfactant and its ability to reduce the surface
tension of water to a very low value are fundamental characteristics
which result in highly efficient and effective performance in
a wide variety of applications. |

| Compatibility and
Solubility |
| HOLOF
LF-03 Surfactant is compatible with soaps, anionic surfactants,
cationic surfactants, other nonionic surfactants and auxiliary
components commonly included in many cleaning products and industrial
processes. |
| HOLOF LF-03
Surfactant is soluble in water and many other common solvents
as shown in Table 5. It is not soluble in some highly aliphatic
compounds such as heptane. |
| HOLOF LF-03
Surfactant is stable in solutions containing up to 49 phosphoric
acid. It is chemically stable in the presence of many other
nonoxidizing acids such as acetic acid, glycolic acid and citric
acid. HOLOF LF-03 is chemically
stable in dilute caustic solutions. |
| HOLOF
LF-03 Surfactant is stable on common builders such as
sodium metasilicate, sodium tripolyphosphate and sodium carbonate.
It is unstable on solid sodium hydroxide exhibiting serious
discoloration and a drop in performance properties. |

| Ross-Miles Foaming |
| Like all nonionic surfactants,
HOLOF LF-03 Surfactant has lower
foaming tendencies than most ionic surfactants. HOLOF
LF-03 Surfactant produces less stable foams than many
competitive surfactants. This feature is illustrated in Figure
3, which shows initial and five- minute Ross-Miles foam heights
for HOLOF LF-03 Surfactant and
the competitive nonionic surfactants. All four surfactants generate
foam initially, which provides the aesthetic appearance of better
cleaning and is desirable from the end-user's point of view.
The foam produced by HOLOF LF-03
Surfactant dissipates faster than that produced by the PAE and
NPE surfactants. Foam instability provides for improved rinsing
and improved operating efficiencies in industrial applications,
which can reduce the need for costly foam control agents. This
trend is noted over a broad concentration range and is maintained
up to the cloud point of the surfactant. |
 |
| |
| Draves Wetting |
The ability of a surfactant
to wet textile substrates rapidly is a key performance property
in many applications. The Draves Wetting test is a widely regarded
laboratory procedure for ranking the relative wetting efficiencies
of surfactants. This test is a timed determination for the
wetting of a cotton skein by dilute surfactant solutions. Short
wetting times are indicative of excellent wetting efficiencies.
Shown in Figure 4 are Draves Wetting times for HOLOF
LF-03 Surfactant and the competitive surfactants. All
of these surfactants are excellent wetting
agents, however, HOLOF LF-03 Surfactant
is shown to be clearly superior to the NPE. HOLOF
LF-03 Surfactant is comparable to the PAE within the
experimental limits of the test method. HOLOF
LF-03 Surfactant also is very effective in wetting other
substrates, such as
polyester, nylon, and polyethylene. |
 |
| |
| Detergency Performance |
Figure 5 demonstrates
the outstanding detergency performance of HOLOF
LF-03 Surfactant on a non-polar oily soil. Detergency
values were determined for HOLOF LF-03
Surfactant and the competitive surfactants. All of the nonionic
surfactants perform well, but even among
these tough competitors HOLOF LF-03 Surfactant
exhibits the best overall performance. The outstanding cleaning
properties of HOLOF LF-03 Surfactant,
combined with its low pour point, resistance to gelling, low
odor, and outstanding biodegradability, make HOLOF
LF-03
Surfactant an ideal surfactant for unitized-dose and other high-performance
specialty detergent products. |
 |
| |
| Hard-Surface Cleaning |
Figure 6 illustrates
the performance of HOLOF LF-03 Surfactant
and the competitive surfactants in an industry standard hard-surface
cleaning test. This testing protocol is designed to evaluate
bucket-dilutable formulations, such as those that are intended
for use in cleaning
kitchen floors or walls. All of these surfactants are candidates
for hard-surface cleaners, and performance is acceptable in
all cases. Owing to its lower odor than the PAE, and better
formulation properties than the NPE, HOLOF
LF-03 Surfactant is the preferred surfactant overall.
