Topical Creams Composed of Lecithin and Triethanolamine Combination

Finding products with a long-lasting moisturizing effect on the skin is somewhat difficult. However, some applications provide protection on the skin or in the layers just beneath the skin and help it stay hydrated.

In such creams, maintaining stability by dissolving in high water content is important. The use of liposomes to prevent water loss from the underlying skin benefits such components. These types of compositions consist of triple matrices.

In this application, the swelling property of lecithin in water is utilized. The composition consists of an oil phase and a water phase.

The oil phase of this composition contains stearate. The water phase in the hand lotion contains liposomes, triethanolamine, and Mono Propylene Glycol, which are dominant in this environment.

Lecithin is a compound with important properties for hair and hair treatments in some studies. It is a compound with lubricating properties for skin and hair. In the use of lecithin in cosmetic preparations, it is used in the range of 1%-2% in shampoos and at a level of 10% in skin oils. It is important whether the skin has a dry or moist structure when using lecithin. On dry skin, lecithin use should be in the range of 0.5% to 0.65%. Using it in higher proportions may cause the skin to dry out further.

What is the Composition of a Topical Cream?

The amount of Triethanolamine (TEA) used in this composition depends on the amount of lecithin used. For every mole of lecithin, 1 mole of Triethanolamine (TEA) is used. Based on this, if 1% lecithin is used, 0.2% Triethanolamine (TEA) is used.

In a formula suitable for skin dryness, triethanolamine (TEA) is 0.4%.

Other components used are as follows.

• Soy lecithin containing 40% Lecithin
• Triethanolamine (TEA)
• PPG 15 Stearyl Ether
• Isopropyl Palmitate
• Carboxymethyl Cellulose (CMC)
• Citric Acid
• Ethyl Alcohol
• Water

The moisturizing cream with the content mentioned above can provide long-term protection against skin dryness. The resulting moisture barrier has very strong properties.

Lecithin is generally used as an emulsifier in skincare products and can increase skin moisture. Triethanolamine, on the other hand, can be used as a pH adjuster or emulsifier in cosmetic products. Both components can play a role in the stabilization of various cosmetic products.
