Tetrahydrocurcuminoids (THC)

Tetrahydrocurcuminoids (THC) are derived from curcuminoids (extracted from the roots of curcuma longa, commonly known as turmeric root). Tetrahydrocurcuminoids are phenolic in nature, acting as antioxidants, protecting against free radicals and preventing the generation of free radicals.   Unlike yellow curcuminoids, THC is a colorless compound which can therefore be used in color free cosmetic products that currently employ conventional and synthetic antioxidants.

Curcuminoids and therefore THC offer protection to the skin and should be considered for inclusion as functional antioxidants in topical preparations. THC scavenges free radicals that are generated through exposure to ultraviolet radiation, chemicals or other environmental stress factors which age the skin. The efficacy of Curcuminoids and THC is also concentration dependent, with THC being even more effective at lower concentrations. THC also helps to improve the shelf life of topical formulations by inhibiting the autoxidation of fats by offering protection against rancidity of the fat components used in the formulation of cosmetics.
 
Tetrahydrocurcumin has been shown to efficiently inhibit tyrosinase. As such, it is an effective skin lightening agent with multi functional topical benefits.  It has been tested to determine its safety for topical use with no irritant or sensitization side effects.
 
The anti-inflammatory effects of THC combined with their efficient antioxidant action render them useful as ingredients in anti-aging formulations, skin lightening and brightening products and topical formulations designed to maintain general skin health and integrity.

Our Customers Say...
Hi, I just wanted to express how happy I am with Lotioncrafter. I have ordered from them three times and this last time I mistakenly put through the wrong shipping address in my order. I called and spoke to Jen and she corrected it immediately. I was very pleased with her efficiency that I had to come in write my own testimonial, something I don't usually do.

The last 2 orders arrived in a timely fashion but this one has taken a little longer because of the memorial day weekend. I knew it was going to be shipped late because on the site, they let the customers know that shipping would be delayed as a result of the holiday. I was very happy with this as well - at least I knew about the possible delay ahead of time.

Thanks Jen for always providing stellar customer service.

I just wanted to say how impressed I am with your cocoa butter. It's less expensive than my other suppliers (when they can get it at all), and I love the way it's so convenient to measure out- no more cutting and getting it all over the place! I will certainly order from you from now on. Thank you!
Amy, (Garden Goddess Bodycare)

WOW! How fun to make my own Quality skin care products. I'm financially challenged and I love that I can make a product that sells for $100 for a fraction of that! If you can follow a recipe, than you can follow these instructions.I recommend ordering the scale and paddle mixer, too. They're a time saver. Thank you Lotioncrafter!

Doris Vienneau, (None)

So happy to have found your wonderful company! As a small skin care business owner/operator, I appreciate the little things that make ordering from you a pleasure. Exceptional products, prompt service, honest sales policies and even refunds for excess shipping estimates! You've got yourself a loyal customer in return!
