TECA (Titrated Extract of Centella Asiatica)
Brief Description
TECA, or Titrated Extract of Centella Asiatica, is a concentrated extract derived from the Centella Asiatica plant. It is composed of key bioactive compounds, including asiaticoside, asiatic acid, and madecassic acid. TECA is celebrated for its wound-healing, anti-inflammatory, and skin-regenerating properties, making it a highly valued ingredient in skincare formulations targeting sensitive or damaged skin.
INCI Name
Centella Asiatica Extract
Appearance
Fine, light beige to off-white powder.
Formulation Guidance
-
How to Formulate:
- TECA is generally incorporated into the water phase or dissolved in solvents such as propylene glycol or ethanol, depending on the formulation.
- It is temperature-sensitive, so it should be added at temperatures below 40°C.
- Usage Rate: Typically used at concentrations of 0.1–2%, depending on the formulation goals.
Scientific Data on Efficacy
-
Benefits:
- Stimulates collagen production, improving skin elasticity and wound healing.
- Reduces inflammation and soothes irritated skin.
- Protects against environmental stressors due to its antioxidant properties.
-
Research and Studies:
- A 2016 study published in Phytomedicine found that Centella Asiatica’s asiaticoside and madecassic acid significantly enhance wound healing and collagen synthesis in dermal cells .
- A review in Journal of Ethnopharmacology highlighted TECA’s anti-inflammatory and skin barrier-repair benefits, making it suitable for managing eczema and psoriasis .
pH Stability Range
- Stable within a pH range of 4–6. Maintaining this pH ensures the stability of its bioactive compounds.
Solubility
- Water-soluble and compatible with hydrophilic solvents like ethanol or glycerin.
Why to Use It in Formulations
TECA is a powerhouse for skin repair and anti-aging formulations. It is particularly beneficial in products designed for sensitive, irritated, or compromised skin due to its ability to support the skin barrier and promote healing. TECA also complements other active ingredients in soothing formulations like serums, creams, and masks.
Stability Considerations
TECA is sensitive to high temperatures and extreme pH ranges. Overheating or exposing it to pH levels outside of its stable range may lead to degradation, reducing its efficacy and antioxidant capacity.
Possible Alternatives
- Panthenol (Vitamin B5): Offers soothing and wound-healing properties.
- Madecassoside: A single, isolated compound from Centella Asiatica with similar benefits to TECA.
- Allantoin: Known for soothing and skin-repairing properties, ideal for sensitive skin formulations.
