8.5.3. Wound Care
Wound care products promote healing and reduce the
chances of infection and scarring. Using halloysite, as a drug
delivery system in cases of burn care can be very beneficial.
Drugs loaded into halloysite tubes and embedded into the base
layer of a bandage can be released over an extended time
period. This increases the duration of drug effectiveness and
reduces the frequency with which a bandage needs to be
changed.
8.5.4. Nanotubes in Personal Care [20]
Safety or efficacy tests on halloysite nanotubes used in
personal care formulas are to be conducted. Natural
nanocontainer for the controlled delivery of glycerol as a
moisturizing agent for the loading and extended release of
glycerol for cosmetic applications.
8.5.5. Skin cleanser agent [24]
When applied without an active agent, the adsorptive
nature of the HNT serves as a hypoallergenic skin cleanser
capable of removing unwanted toxins and aesthetically
unpleasing oils. The clay performs as a gentle exfoliator,
drawing dead skin cells away from the surface to leave it fresh,
young, and healthy.
8.5.6. Use of HNTs in synthesis of
8.5.6.1. Silver Nanorods for Antibacterial Composite Coating [20]
Silver nanorods were synthesized inside the lumen of
the halloysite by thermal decomposition of the silver acetate,
which was loaded into halloysite from an aqueous solution by
vacuum cycling. The composite of silver nanorods encased in
clay tubes with the polymer paint was prepared, and the
coating antimicrobial activity combined with tensile strength
increase was demonstrated.
8.5.6.2. Gold nanoparticles [25]
Gold nanoparticles were synthesized by reduction of
HAuCl4 using halloysites. The results show that the gold
nanoparticles have strip-like, subcircle, and irregular shape,
which are single crystals or polycrystals.
8.5.7. Use of HNTs in protecting environment
Sorbents for contaminants and pollutant:
HNTs can be used as nano-adsorbents for the removal of the
cationic dye methylene blue from aqueous solutions. Also it
can be used in removal of Zn (II) from aqueous solution [26].
