This work attempts to synthesize gold nanomaterials using a matrix as a barrier to the growth of gold clusters, which tend to grow uncontrolled. The matrix used in the study is mono glycerol stearate, which is a compound of esters formed by glycerol and stearic acid. This matrix will inhibit the formation of naturally sustainable gold clusters. This inhibition results in no gold deposits being produced in this synthesis. The results show that nanogold can be safely used in cosmetics, especially anti-aging cosmetics.
Nanogold synthesis procedure
Synthesis setup included an Erlenmeyer flask, magnetic stirrer, and hot plate. Ten milliliters of gold solution (HAuCl4) were added to the flask, and the temperature was increased to 80 °C while the stirrer operated at 300 rpm for 13 minutes. Matrix mono glyceryl stearate was then melted and added to the flask, followed by 1 mL of sodium citrate as a reducing agent. Observations were made regarding the changes occurring during the 7-minute synthesis period. The concentration of mono glyceryl stearate used in this synthesis is 0.2%, producing gold clusters with a size of 80-200 nm. The matrix concentration can be increased to produce smaller gold clusters.

It used the D-optimal experimental design to optimise the formulations of O/W cosmetic emulsions. The emulsifier was cetaryl glucoside, a natural, biodegradable, nonionic emulsifier at a low concentration (1%), and lipophilic co-emulsifiers (stearic acid, cetyl alcohol, stearyl alcohol, and glyceryl stearate) were added to the formulations to stabilise them.
· Formulation Design
The mixture studied was a four-component system: a mixture of lipophilic co-emulsifiers: stearic acid (X1), cetyl alcohol (X2), stearyl alcohol (X3), and glyceryl stearate (X4). The sum of the amounts of co-emulsifiers in each formulation was chosen to be 5%. The contents of each co-emulsifier ranged from 0% to 5%, so the effects of both single co-emulsifiers and combinations could be evaluated this way.
· Results
The rheological, pH and specific conductivity characteristics of cosmetic emulsions stabilized with low amounts of the natural emulsifier cetearyl glucoside were alterable by changing the formula of the co-emulsifier mixture. According to the research, glyceryl stearate was the main emulsifier that has an impact on the performance of emulsions.
