SKIN CARE 79
moisture evaporates from the surface. Skin applied with SDS alone had higher concentrations of water near the surface (Fig 7). As noted, SDS disrupts the water content in the stratum corneum – shown by the concentration of bright red, yellow and orange on the skin — and has the potential to cause damage to the stratum corneum. Skin applied with Polyglyceryl-10 caprylate/caprate and SDS surfactants matched the control (Fig 8). Much of the water content exists below the surface of the skin and stratum corneum. This result shows the balance of water in the skin is not as affected by SDS when the skin is is in contact with Polyglyceryl-10 caprylate/caprate mild surfactant. Thus Polyglyceryl-10 caprylate/caprate mild surfactant can help maintain the stratum corneum moisture balance, and protect the skin from potential damage caused by harsh surfactants.
Conclusion
Polyaldo 10-1-CC mild surfactant delivers the best of both worlds. It offers an excellent irritation profile, with mildness on a par with PEG-80 sorbitan laurate, combined with the initial flash foaming speed of decyl glucoside, a moderate to severe irritant (based on our study).

foam structure faster than PEG-80 sorbitan laurate, and creates a more stable foam structure and creamier foam. It has higher surface activity than PEG-80 sorbitan laurate, resulting in efficacious cleansing and a better cost-performance ratio. Classified as very low-irritating, it is a gentle surfactant for skin and hair applications where mildness is needed. In addition, Polyaldo 10-1-CC mild surfactant mitigates surfactant penetration into the stratum
corneum, protecting skin from potential damage caused by harsh surfactants and maintaining the stratum corneum moisture balance.
