Triethanolamine (TEA)

Triethanolamine

1. pH Adjuster

Triethanolamine is often used to adjust and stabilize the pH of cosmetic formulations. It helps bring the pH of acidic formulations (such as those with Carbopol, AHA, or citric acid) to a more skin-friendly level (usually around pH 5–7).

How to Use:

• Concentration: Typically, 0.1%–0.5% Triethanolamine is used to adjust the pH.
• Incorporation: After mixing your formulation, check the pH. Slowly add Triethanolamine drop by drop to the formulation while stirring until the desired pH level is reached. Be cautious not to add too much, as excessive TEA can lead to skin irritation.

2. Emulsifier

Triethanolamine is commonly used in oil-in-water emulsions, where it helps to combine and stabilize the oil and water phases of creams, lotions, and other emulsified products.

How to Use:

• Concentration: Use 0.5%–1.5% Triethanolamine as an emulsifier, depending on the formulation.
• Incorporation: Add Triethanolamine to the water phase before combining with the oil phase. It will help emulsify the oil and water, creating a smooth, stable mixture.

3. Surfactant Booster

Triethanolamine is often included in formulations with surfactants (such as cleansers and shampoos) to enhance the foaming and cleansing action. It works by neutralizing acidic surfactants, making them more effective.

How to Use:

• Concentration: Use 0.5%–1% Triethanolamine to boost surfactant performance.
• Incorporation: Add Triethanolamine to the formulation in the water phase, especially if using acidic surfactants like anionic surfactants (e.g., SLS, SLES). It helps neutralize them, improving foam formation and mildness.

4. Stabilizer for Gels and Creams

Triethanolamine is often used to stabilize gel formulations (such as those containing Carbopol) by adjusting the pH and ensuring the polymer thickens properly.

How to Use:

• Concentration: Use 0.2%–1% Triethanolamine for gel stabilization.
• Incorporation: After adding Carbopol or another gelling agent, mix the product and check the pH. Slowly add Triethanolamine while stirring until the desired viscosity and pH are achieved.

5. Buffering Agent

Triethanolamine is used as a buffering agent in formulations to help maintain a consistent pH over time, especially in products like lotions, serums, and hair care treatments.

How to Use:

• Concentration: Use 0.2%–0.5% Triethanolamine for buffering purposes.
• Incorporation: Add Triethanolamine to the water phase before mixing other ingredients. It will help maintain the pH balance and prevent drastic shifts in the formulation.

• Form - Powder

For external use only. Avoid contact with eyes. In case of irritation, discontinue use and consult a physician. Keep out of reach of children. Store in a cool, dry place.
