Further, it minimizes porosity and provides some protection against thermal and mechani- cal damage. To increase its adsorption, the formula can be applied to hair and worn under a plastic cap for 20 to 30 min under a warm dryer.This formula also emphasizes the more recent use of D-panthenol in hair care.


While both D,L-panthenol and D-panthenol have been utilized, some believe the“real” active in the DL racemic blend is only the “D” molecule, and it must be kept at a fairly low tempera- ture to avoid its racemization.


The emollient after-feel of this conditioner is provided by cetyl alcohol, which also stabilizes the emulsion, while the spherical-shaped molecules of hydrogenated polydecene act as a lubricant, deeply penetrating into the hair fbers by diffusion.
The preparation of this formula is as follows:
mix A and heat to 80°C; add B to A at 80°C; mix for 30 min, then cool to 40°C; add C while mixing, then cool to room temperature.
