Valuable CAS 1286686-34-7 / SKIN CONDITIONING

A versatile botanical wax derived from sunflower seeds, Helianthus Annuus Seed Wax functions primarily as an emollient and skin conditioning agent. It creates a protective, moisture-locking barrier on the skin's surface, enhancing hydration while simultaneously improving product texture and stability.

Science

Mechanism of Action

Helianthus Annuus Seed Wax operates by forming an occlusive film on the stratum corneum, which significantly reduces transepidermal water loss (TEWL) and thus boosts skin hydration. Its rich composition of long-chain fatty acids, triglycerides, and phytosterols contributes to its skin-softening and conditioning properties, with reported potential for anti-inflammatory effects. Furthermore, it serves as a natural thickener, consistency modifier, and stabilizer in cosmetic formulations.

Key findings

  1. 01 In human use studies, Helianthus Annuus Seed Wax at concentrations of 3.34% to 4% demonstrated no dermal irritation or sensitization in individuals with sensitive skin when incorporated into leave-on products like mascara and lipstick.
  2. 02 At concentrations of 1% to 3%, it effectively improves emulsion stability and increases viscosity in creams and lotions, contributing to a pleasant texture and forming a protective layer on the skin.
  3. 03 Formulations containing Helianthus Annuus Seed Wax at up to 5% exhibit enhanced firmness and stability, particularly in products such as lip balms, creams, and body butters.
  4. 04 When utilized in lip balms at 5% to 10%, it aids in achieving a firm yet smooth texture, providing sustained hydration and protection.

Stability

Possesses robust thermal stability due to its high melting point, typically ranging from 74-80°C, which protects formulations from melting or spoilage at elevated temperatures. It is integral for stabilizing emulsions and refining product consistency, and is optimally incorporated into the fat phase between 70°C and 80°C during the melting and mixing stage.
