[0032] The following Examples will provide details as to the
manufacture of several compositions in accordance with the
invention.
EXAMPLE 1
[0033] The individual chemical components of the present invention
are mixed in accordance with common procedures. Particularly, a
mixing kettle is used to blend the ingredients. Any of the kettles
or other machines or equipment that will come into contact with the
ingredients, including valves, pumps, hoses, and utensils, must be
thoroughly cleaned, sanitized, rinsed, and dried before use.
[0034] In addition, the room or enclosure in which the mixing takes
place must be relatively low in humidity.
[0035] These precautions are taken so that the finished product is
a clear liquid is free of water. The individual chemical components
used in connection with the present invention are sensitive to
water. Thus, contact of those components with water can have an
adverse effect.
[0036] To manufacture the product of the invention, 30.0 pounds of
Fibershield 5480, which contains C6-C14 perfluoroalkylethyl
acrylate/hema copolymer, butyl acetate, and aliphatic isoparaffin,
is added to a mixing kettle.
[0037] Next, 70.0 pounds of a C12-C14 isoparaffin (Soltrol 170) is
added to that kettle.
[0038] These, this chemical mixture and the added isoparaffin are
blended for thirty (30) minutes to create a clear liquid, and the
finished product.
[0039] The finished product is then pumped from, removed, or
otherwise discharged from the mixing kettle.
[0040] The kettle and all equipment used in connection with the
invention must be cleaned immediately. Failure to immediately and
thoroughly clean the surfaces of both the kettle and the surfaces
of the equipment that are used in the manufacture of the finished
product will result in the formation upon those surfaces of a film
that cannot be easily cleaned with either water or solvents.
EXAMPLE 2
[0041] Each of the procedures, equipment, and techniques used in
Example 1 are used in this Example 2. The only difference is in the
amounts of the chemical component ingredients.
[0042] Specifically, in this embodiment, 15.0 pounds of the
chemical mixture containing C6-C14 perfluoroalkylethyl
acrylate/hema copolymer is added to the kettle. Next, 85.0 pounds
of an added C12-C14 isoparaffin (Soltrol 170) is added to the
kettle.
EXAMPLE 3
[0043] Each of the procedures, equipment, and techniques used in
Example 1 are used in this Example 3. The only difference is in the
amounts of the ingredients.
[0044] Specifically, in this embodiment, 35.0 pounds of the
chemical mixture containing C6-C14 perfluoroalkyl ethyl
acrylate/hema copolymer is added to the kettle. Next, 65.0 pounds
of an added or additional C12-C14 isoparaffin (Soltrol 170) is
added to the kettle.
EXAMPLE 4
[0045] Each of the procedures, equipment, and techniques used in
Example 1 are used in this Example 4. The only difference is in the
amounts of the ingredients.
[0046] Specifically, in this embodiment, 25.0 pounds of a chemical
mixture containing C6-C14 perfluoroalkyl ethyl acrylate/hema
copolymer is added to the kettle. Next, 75.0 pounds of an
additional C12-C14 isoparaffin (Soltrol 170) is added to the
kettle.
EXAMPLE 5
[0047] Each of the procedures, equipment, and techniques used in
Example 1 are used in this Example 5. The only difference is in the
amounts of the ingredients.
[0048] Specifically, in this embodiment, 15.0 pounds of a chemical
mixture containing C6-C14 perfluoroalkyl ethyl acrylate/hema
copolymer is added to the kettle. Next, 85.0 pounds of an
additional isoparaffin, here C12-C14 isoparaffin (Soltrol 170), is
added to the kettle.
EXAMPLE 6
[0049] Each of the procedures, equipment, and techniques used in
Example 1 are used in this Example 6. The only difference is in the
type of ingredients.
[0050] Specifically, in this embodiment, 70.0 pounds of a C10-C13
isoparaffin (Soltrol 130) is substituted for the Soltrol 170.
[0051] It should be understood that this substitution of Soltrol
130 for Soltrol 170 can be made in any of the remaining Examples
2-5.
[0052] Products made in accordance with the invention are colorless
and odorless. The addition of the isoparaffin results in a product
that enables both better deposition, and a more uniform coating on
the hair, as compared to the assignee's prior composition.
[0053] In addition, the product of the invention coats the hair
fiber, and protects the hair against the deleterious effects of
moisture. More particularly, the product of the invention protects
permanent-treated hair against the deleterious effects of rain.
