Anhydrous – means without water;
anhydrous lanolin is used in Kabana products as a raw material so that
it can mix with the Eldorado Springs water and emulsify the mixture.
Antioxidant – beneficial chemicals
that are often botanic in origin and actively seek to react with oxidative
chemicals. Often these oxidative chemicals are called free radicals, and
have extra electrons that have been excited to a highly reactive state
by UV radiation. Antioxidants act as a shield would to protect your skin
from these dangerous oxidative compounds, which can attack critical elements
of your skin cells and eventually lead to skin cancer. Wikipedia

Cold Expeller Press – a continuous-feed
machine used to extract oils from organic materials under high pressure
yet without the use of heat that can damage the extracted oils.
Deionized (DI) water – water that
has been stripped of all its normally occurring ions. It is a cheaper
form of purifying water than distilling it, as in distilled water, but
doesn’t remove non-ionic impurities such as hydrocarbons and sometimes
has an acidic component due to absorption of atmospheric carbon dioxide
and production of carbonic acid. Deionized and distilled water can rob
your body of the ions necessary for life via dilution, so while useful
in terms of scientific experimentation, it is better to use water with
a proper ionic balance. Wikipedia

Emollient – fatty compounds that
associate with water and seal it in your skin, providing a moisturizing
effect.
Emulsifying agent – a compound that
can associate with both water and oil, and provides stability to oil and
water mixtures to create a lotion.
Essential Fatty Acids – are certain
unsaturated fatty acids that cannot be produced by the human body yet
are essential to maintaining proper biochemistry and homeostasis. See
Fatty Acids.
Fatty Acids – a hydrocarbon chain
that has a carboxylic acid at one end. These biochemicals form triglycerides.
Several are essential for life. Wikipedia
– Fatty acid
Hydrocarbons – chemicals that contain
hydrogen and carbon, hence hydrocarbon – and generally produced
from petroleum oil. All FDA approved sunscreens are considered hydrocarbons,
although these compounds also contain oxygen, Nitrogen and sometimes other
elements.

Lotion – an emulsified mixture of
oil and water.
Oxidation – a chemical process, mediated
by UV radiation that results in skin damage. See Antioxidant.
Retinol – the chemical name for Vitamin
A.
Saturated fat – fats that contain
no double bonds. (see Unsaturated fat below) Stearic acid is saturated.
Take a look at its structure here.
SPF – an acronym for Sun Protection
Factor. See Erik’s September newsletter
article for more information. FDA uses the Minimal
Erythemal Dose (MED) experiment to calculate this value. So far, FDA
has not developed methods to evaluate how to label UVA protection, since
the MED does not measure UVA damage – it only measures UVB which
causes the burn (erythema – the medical term for redness).
Sun blocks are minerals approved by FDA for use in UV protective
formulations at various concentrations. These chemicals are not soluble
in water or hydrocarbon solvents and are classified as refractory, which
is another word for a ceramic. FDA has approved two such minerals as sun
blocks – zinc oxide and titanium dioxide. Zinc oxide has a broader
UV absorption profile than titanium dioxide. New manufacturing technologies
enable these compounds to be produced in nanofine sizes – the zinc
oxide used in Kabana products has an average particle size of 55nm (55
billionths of a meter or 55 millionths the diameter of a human hair),
which promotes transparent formulations of this compound. Zinc oxide and
titanium dioxide are approved as sun blocks in concentrations up to 25%
of a lotion’s weight.
Sunscreens are hydrocarbon–based chemicals that are
approved by FDA for use in UV protective formulations at various concentrations.
There are currently fourteen FDA-approved sunscreens. Some absorb UVA,
some UVB and some overlap a bit. They include the following (with maximum
FDA-approved concentration %):
p-aminobenzoic acid (PABA) (15%)
Avobenzone (3%)
Cinoxate (3%)
Dioxybenzone (3%)
Ensulizole (4%)
Homosalate (15%)
Menthyl anthranilate (5%)
Octocrylene (10%)
Octyl dimethyl PABA (8%)
Octylmethoxy cinnamate (7.5%)
Octyl salicylate (5%)
Oxybenzone (6%)
Sulisobenzone (10%)
Trolamine salicylate (12%)

Triglycerides – fats that contain
three fatty acids and one molecule of glycerol, less three molecules of
water lost during the bonding (esterification) process. Wikipedia
– Triglyceride. Fats that occur in nature are generally of this
type.
Unsaturated or Polyunsaturated – This
term describes how many double bonds a fatty acid chain may have. The
monounsaturated essential fatty acid Oleic Acid has only one Carbon-Carbon
double bond, whereas Linoleic Acid has two, and Linolenic Acid, three.
As a general rule, the more unsaturated a molecule is, the lower its melting
point. This is because the carbon chains don’t align evenly, due
to the bend created by the double bond. Take a look at Linolenic acid
here Wikipedia
– Unsaturated Fat
USP – An acronym for United States
Pharmacopoeia – this is a regulatory body that oversees the standardization
of personal care and pharmaceutical chemical purity. Any compound labeled
USP must meet the strictest of purity qualifications. USP
Vitamin A – Otherwise known as retinol
has important roles in maintaining bone and vision health. It is also
used in skin care formulas to promote a youthful appearance, and works
by increasing skin cell growth rates and collagen production. Wikipedia
– Retinol
Vitamin E – a potent antioxidant
that also encourages skin healing and reduces scarring after injury. More
