SPENT GRAIN WAX.

Valuable / SKIN CONDITIONING, VISCOSITY CONTROLLING

Spent Grain Wax is an advanced emollient rich in beneficial fatty acids, designed to fortify the skin's natural barrier. It delivers significant, long-lasting hydration while actively calming irritated skin by modulating key inflammatory responses.

Summary

Skin-Conditioning Viscosity Controlling Emollient Anti-inflammatory Barrier Support Hydrating

Science

Mechanism of Action

This ingredient functions as an effective emollient, creating a protective film on the skin's surface to lock in moisture and enhance overall skin texture. Its rich composition of fatty acids is crucial for supporting the regenerative function of the skin barrier. Moreover, Spent Grain Wax actively moderates inflammatory pathways by inhibiting E-selectin expression, an initial step in the inflammatory cascade, and reducing interleukin-1alpha (an inflammatory marker) by up to 58%, thereby alleviating irritation and histamine-related discomfort.

Key findings

  1. 01 A cream incorporating Spent Grain Wax within a blend (STIMU-TEX AS®) demonstrated efficacy comparable to 1% hydrocortisone cream in treating and maintaining mild to moderate childhood atopic dermatitis, showing significant SCORAD score improvement after two weeks.
  2. 02 Ezerrawax™ (a blend containing Spent Grain Wax) at a 5% concentration reduced histamine-associated symptoms by up to 30% within 5 minutes when tested on 10 women.
  3. 03 A combination cream featuring Spent Grain Wax in a blend (STIMU-TEX AS™) and Saccharide Isomerate significantly increased skin hydration, decreased Transepidermal Water Loss (TEWL), and reduced erythema following fractional CO2 laser procedures, with no adverse events reported.
  4. 04 A cream containing Spent Grain Wax, shea butter, argania spinosa kernel oil, and tapioca starch showed significant improvement in intertrigo lesions within the first week, comparable to 1% hydrocortisone cream.

Stability

Spent Grain Wax, often utilized in proprietary blends, maintains stability within a pH range of 3.5 to 6.5. For optimal preservation, it should be stored light-protected in a cool, dry environment. When formulating, it is oil-soluble and may require gentle heating to 70-80°C to melt and enhance solubility; however, temperatures exceeding 80°C must be avoided to maintain its integrity.
