CLNIQUE repairwear eye cream has this in it


Hydrogenated form of the skin-restoring ingredient lecithin.

<< As for Lecithin: Phospholipid found in egg yolks and plants. Widely used in cosmetics as an emollient and water-binding agent. Lecithin also has skin-restoring ability. >>

For our collagen extraction, we mostly use from fish or plant based. We are doubtful about this source of information too.

The brand is now available in Middle East too. We do not have such issues from Muslim groups.



低于浓度15%的时候, 用来加入可清洗的护肤品是安全的

主要是作为皮肤渗透剂,如果配方好的话,帮助皮肤吸收. 配方差的话,那么皮肤会吸入有害物质

Is Hydrogenated Lecithin Safe?
The safety of lecithin and hydrogenated lecithin has been assessed by the Cosmetic Ingredient Review Expert Panel. The Expert Panel evaluated the scientific data and concluded that lecithin and hydrogenated lecithin are safe as used in rinse-off products. However, the Panel limited the use of lecithin and hydrogenated lecithin in leave-on products to concentrations less than or equal to 15 percent.

Since hydrogenated lecithin functions as a penetration enhancer, caution should be exercised when it is combined in formulations with other ingredients that may be harmful if absorbed through the skin.

It is possible for some people to have allergies to hydrogenated lecithin since it can be derived from soybeans, eggs, and milk, which are common allergenic foods. Those that are highly sensitive to these foods might react to hydrogenated lecithin

Hydrogenated Lecithin Description
Hydrogenated lecithin is a phospholipid that is produced by controlled hydrogenation of the skin-restoring ingredient lecithin. It can be manufactured synthetically or may be derived from animals (egg yolk is a source) or plants.

Reported functions of hydrogenated lecithin in skin care and other personal care formulations include dispersing agent, skin-conditioning emollient, and emulsifier. As with other phospholipids, research shows it can enhance the penetration of other skin care ingredients in a formulation for greater efficacy. It is used in advanced active ingredient dlivery systems like liposomes and micelles, which improve adsorption and penetration through the skin’s lipid barrier.

As a raw material, the appearance of hydrogenated lecithin can vary depending on the source. Descriptions range from a white to beige-gray powder appearance.

According to the Cosmetic Ingredient Review (CIR) Expert Panel’s 2020 safety assessment, the maximum reported concentration of use was 5% (for face and neck products). Any amount 15% or below was deemed safe for rinse-off and leave-on products.

The CIR Expert Panel concluded that the safety data is insufficient for products containing hydrogenated lecithin that may be inhaled (such as sprays). As such, it is uncommon to find this ingredient in those types of products.
