K-20W Jojoba Esters is a hydrolised ester that, when combined with glycerine in a formulation, provides significant long tem moisturisation benefits. Tests demonstrate that using a ratio of 3:1 (Glycerine to K-20W) provides 24 hour moisturisation.
This ability makes the combination an ideal component in any skin cream or lotion but particularly in formulations for dry skin.
A study investigated a synergy between Floraesters K-20W Jojoba and glycerin to increase 24h moisturisation
Skin hydration was measured as transepidermal water loss (TEWL). Results found that significantly higher moisturisation occurred in the topical formulations containing 3.75% glycerin and 1.25% Floraesters K-20W Jojoba. Results indicate that glycerin and Floraesters K20-W Jojoba work in tandem to enhance 24 hour skin moisturisation
Usage Rate: Ideally 1.25% of your formulation in combination with 3.75 Glycerine. Add to the water phase
Although expensive bear in mind that a 100ml bottle at £6 will be sufficient for 8 litres of finished product at the recommended usage rate.
