Peat mentioned that possibility, but even saturated fats oxidize in the body with difficulty.

You may have also heard an ingredient list referred to as an INCI list, which stands for “international nomenclature of cosmetic ingredients” and is the system for listing ingredients by their scientific nomenclature. It’s a system that was first developed in the 1970s and has since been adopted for use in the European Union, China, Japan, and many other countries. With few exceptions, INCI labeling names are the same in every country.

Ingredient Order

In the cosmetics industry, ingredients are always listed in order of prominence. This means that the ingredients follow an order of highest percentage to lowest percentage. Typically, the first five or six ingredients in the list make up the majority of the product, and the following ingredients are used in comparatively small quantities.

Thanks for more info. Just to clarify, are you saying (per your comment on "even saturated fats oxidize in the body with difficulty"), that if a good quality, cold-processed jojoba oil is mixed with pure anhydrous lanolin, the lanolin would protect against the jojoba oxidizing?

If one wanted to be safe, for purposes of moisturizing and to protect against rancidity, oxidation, sun exposure, cancer, etc, would it be best to use a pure anhydrous lanolin alone?

Thanks very much for helping me understand this.

P.S. Would you also clarify, is it best to avoid using lanolin oil if one has access to pure anhydrous lanolin, for all the reasons stated above? Thank you.

- A saturated fat is not an antioxidant

"The antioxidant function of vitamin E is critical for the prevention of oxidation of tissue PUFA. Animal experiments have shown that increasing the degree of dietary fatty acid unsaturation increases the peroxidizability of the lipids and reduces the time required to develop symptoms of vitamin E deficiency."

"Since systematic studies on the vitamin E requirement in relation to PUFA consumption have not been performed in man, recommendations for vitamin E intake are based on animal experiments and human food intake data. An intake of 0.6 mg alpha-tocopherol equivalents per gram linoleic acid is generally seen as adequate for human adults. The minimum vitamin E requirement at consumption of fatty acids with a higher degree of unsaturation can be calculated by a formula, which takes into account the peroxidizability of unsaturated fatty acids and is based on the results of animal experiments. There are, however, no clear data on the vitamin E requirement of humans consuming the more unsaturated fatty acids as for instance EPA (20:5, n-3) and DHA (22:6, n-3)."

- The saturated fat (straight-chain esters), which is solid at room temperature, is removed to make a liquid/oil product.

"Lanolin fatty acids are obtained through hydrolysis of lanolin for the recovery of lanolin alcohol. In addition, they are already present in a large proportion as free fatty acids in raw wool grease. It is a highly complex mixture of fatty acids, composed of roughly 40% by weight of straight chain acids, 20% of branched chain acids and approximately 40% of hydroxy acids. The majority of this mixture of fatty acids is saturated with carbon chain lengths from C8 to C40 that form a hard, waxy, buttery coloured solid."

- There is refined and unrefined lanolin

"Lanolin is secreted by the sebaceous glands of sheep and is a thick, greasy, yellow substance in its unrefined state. When this raw material is processed to remove its impurities, the resulting substance is called anhydrous lanolin."

---

"Lanolin has been found to contain traces of pesticides."

"Lanolin is a natural wax coating on sheep wool that is removed by boiling the wool and collecting the wax. Sheep are often treated with a pesticide dip which contains chemicals such as DDT, lindane, and diazinon to control parasites."

"Lanolin is a big ingredient to stay away from if you have acne-prone skin—and even worse, it can go by different names, so you have to be really careful when checking your product labels. "Lanolin is the sebum, or skin oil of sheep,” he explains. “Unfortunately, lanolin is highly comedogenic and can cause more skin breakouts." Other names for lanolin are, acetylated lanolin alcohol, ethoxylated lanolin, PEG 16 lanolin and solulan 16. Klein adds lanolin can also be a trigger of contact dermatitis."

You may have noticed the many mommy bloggers ringing the alarm bells on this ingredient. What you may, or may not, have noticed are their disclaimers which state “written while serving as a paid brand ambassador for [specific brand of organic lanolin]” or similar verbiage.

The top 3 pesticides used on sheep in 2005 were permethrin, fenvalerate, and malathion, according the Organic Trade Association.

The first 1 has been around for many decades, the other 2 are newer.

If bloggers are going haywire over the 5.9 ppm, then why aren’t they doing the same regarding the 20 ppm tolerance of permethrin for spinach or lettuce?

Or better yet, the bloggers who cry wolf that those sheep are eating contaminated alfalfa. Yes, that is true. But the threshold of that particular pesticide, as an example, is 20 ppm for alfalfa forage (same as the spinach we eat) and 45 ppm for alfalfa hay.

Lanolin, in and of itself, is not toxic. If it is truly purified lanolin ointment, the toxins (i.e. pesticides) are in extremely miniscule amounts or at least should be.

The most disturbing thing is not any of the points we discussed, rather it’s the country of origin.

China is the top exporter for “derivatives of wool grease” (i.e. lanolin), accounting for 27% of exports (9). While the US produces much of its own lanolin, its worth noting that 10% of global exported lanolin is purchased by the US. That may not sound like much, but remember we are only 4.4% of the global population, so if we’re using 10% of exported lanolin, it’s a lot relative to our population.

Also, whatever brand of product you use, it may not be a bad idea to find out exactly where they’re sourcing their lanolin from. Remember, when a cream is “made in the USA” it does not automatically mean all of the cream’s individual ingredients were made in the USA.

Only you can decide whether or not you feel confident in using lanolin!

Very interesting. Do you personally use lanolin? You seem to know a lot about it, just curious. Do you think a product sourced from New Zealand/made in New Zealand would be a safe bet, if other brands do not specify country of origin?

If pure anhydrous lanolin is mixed with a fresh organic source of jojoba oil, would the fat of the lanolin protect against (further) oxidation of any PUFA in the jojoba oil, do you think?
I no longer use it

problem solved
