LET'S MAKE A SHAMPOO
LET’S
MAKE A SHAMPOO
Shampoo
is used to wash our hair. All people use it to clean and take care of their
hair combines with other hair treatment products. Now, there are many
commercial shampoos in the market with different advantages. But not all people
can use it because some shampoo is not appropriate with certain kind of hair.
That’s why they might want to make their own shampoo to avoid hair problems like
scratch. They want to avoid the chemicals in commercial shampoos that can
damage their hair so they decide to make their own shampoo.
The
basic concept of shampoo was is Back in year olden days, shampoo was soap,
except with additional moisturizer so that it didn’t strip the natural oils
from your scalp and hair.
Although
a shampoo can be solid, it is easier to use if there is enough water to make a
gel or liquid. Shampoos tend to be acidic because if the pH gets too high
(alkaline) the sulfur bridges in the hair keratin can break, damaging your
hair. This recipe for making your own gentle shampoo is chemically a liquid
soap, except vegetable-based (many soaps use animal fat) and with alcohol and
glycerin added during the process. Make it in a well-ventilated room or
outdoors and be sure to read all of the safety precautions on the ingredients.
Shampoo
ingredients
· 2 lb 10 oz
olive oil
· 1 lb 7 oz of
solid-type vegetable shortening
· 1 lb coconut
oil
· 10-1/4 oz
lye (sodium hydroxide)
· 2 pints
water
· 1-1/2 oz
glycerine (glycerol)
· 1/2 oz
alcohol (I’d use vodka or other food-quality ethanol and call it close enough.
Do not use methanol)
· 1-1/2 oz
castor oil
· Essential
oils (optional), such as peppermint, rosemary, lavender, for fragrance and
therapeutic properties
HOW TO MAKE SHAMPOO
1. In the large
pan, mix together the olive oil, shortening, and coconut oil.
2. In a
well-ventilated area, preferably wearing gloves and eye protection. In case of
accidents, mix the lye and water. Use a glass or enameled container. This is an
exothermic reaction, so heat will be produced.
3. Warm the
oils to 950F-980F and allow the lye solution to cool to
the same temperature. One of the easiest ways to accomplish this is to set both
containers into a large sink or pan full of water that is at the correct
temperature.
4. When both
mixtures are at the proper temperature, stir the lye solution into the oils.
The mixture will turn opaque and may darken.
5. When the
mixture has a creamy texture, stir in the glycerine, alcohol, castor oil, and
any fragrance oils or colorants.
6. You have a
couple of option here. You can pour the shampoo into soap molds and allow it to
harden. To use this shampoo, either lather it with your hands and work it into
your hair or else shave flakes into hot water to liquefy it.
7. The other
option is to make liquid shampoo, which involves adding more water to your
shampoo mixture and bottling it.
You
may have noticed that many shampoos are pearlescent. You can make your homemade
shampoo glittery by adding glycol distearate , which is a natural wax derived
from stearic acid. The tiny wax particles reflect light, causing the effect.
