Phenylethyl Resorcinol or more commonly known as 'SymWhite' is both an antioxidant and a skin-lightening agent that is naturally derived from the scotch pine bark tree. It has an excellent ability to remain stable in most cosmetic formulations making it a highly efficient skin-lightening agent. It is best dissolved in oil or propylene glycol and is stable at a pH of 3.5.

Unlike other powders, SymWhite is highly sensitive to heat and should be mixed at the very last step of a product formulation. The formula temperature must be below 40°C.

Compatibility

SymWhite is compatible with most skin-lightening actives including SepiWhite, GigaWhite, Vitamin C, L-Glutathione, Kojic Acid, and Kojic Dipalmitate.

Note: Avoid mixing too many powders into one lotion, aim for no more than 3 active skin lightening ingredients in one formulation.

To add SymWhite powder to your skin lightening cream or natural brightening lotion, it involves a simple 4 step process.

1. Ensure all your ingredients are ready. 1) Any base cream (skin brightening/lightening lotions work best) 2) SymWhite powder 3) Vegetable Oil/Propylene Gylcol. You will also require two pots (a smaller and a larger one).

2)  Mix 1-2teaspoon (about 5-10 grams) in with a small amount of vegetable oil or PG. Do not use water.  Place the mixture into a stainless steel pot, and use the double boiling method. Place the pot on top of another pot with warm water under heat. Mix, and wait until the powder has fully dissolved with the oil (it should not be grainy or powdery). 

3) Add the fully dissolved powder (with the oil or glycol) into your base lotion until it's fully mixed together. Add a little at a time, until it's all completely absorbed. 

Voila, you have just turned an ordinary brightening lotion, into a potent skin lightening lotion which you can use for at least 6 months.   Repeat the process as you wish.  Adding more than one skin lightening active will increase the potency of the lotion.  

Precautions:

SymWhite Powder is not known to have any side effects and is generally safe for most people. 

However, this product is not intended for internal use.  Do not add the powder to products containing lactic acid, or AHAs as this can affect the end pH of the lotion. If redness, itching, or irritation occurs, discontinue use immediately.

You should aim to use no more than 2-5% of any of our skin lightening additives in a single formulation. Using more than necessary can be counterproductive. Calculating percentages in a lotion is very straightforward, and guidelines have been shown below.

To make a 2% lotion, use 2grams of the Sym White Powder in a 100gram base lotion.

To make a 5% lotion, use 5grams of the Sym White Powder in a 100gram base lotion.

Although the above guidelines are sufficient for the application of most powders - the utilization rate of SymWhite powder is between 0.1% - 1% - with a recommended utilization rate of 0.5%.
