Description:
Vitamin C is a very useful vitamin C derivative. It is not only very stable in terms of chemical substances and is a non-discoloring vitamin C derivative, but also a hydrophilic and lipophilic substance, which greatly expands its applicable chemical book scope, especially in daily chemical applications. 3-O-ethyl ascorbic acid ether can easily pass through the stratum corneum into the dermis. After entering the body, it is very easy for the biological enzymes in the body to decompose and exert the biological effects of vitamin C.

Structural characteristics:
3-O-ethyl ascorbic acid ether is also called vitamin C . Vitamin C cannot be directly absorbed by the skin due to its 4 hydroxyl groups in its structure, and is easily oxidized and discolored, so its use as a whitening agent in cosmetics is limited. Vitamin C prepared by Chemicalbook after alkylation of the 3-hydroxyl group is a vitamin C derivative that does not change color and does not affect its biological activity, thus filling the gap in similar products on the market. Studies have shown that vitamin C ethyl is easily decomposed by enzymes after entering the skin and exerts the effect of vitamin C.

Use:
Vitamin C (VC ) is a lipophilic and hydrophilic amphoteric vitamin C derivative. It not only retains the redox effect of vitamin C but is also very stable. It is a non-discoloring vitamin C derivative and it is a lipophilic and hydrophilic amphoteric substance. This not only makes it extremely convenient to use in formulas, but also makes it easier to penetrate the stratum corneum and enter the dermis. After entering the skin, it is easily decomposed by biological enzymes to play the role of vitamin C, thereby improving its bioavailability.

Application:
1. Inhibit the activity of tyrosinase by acting on Cu2+, blocking the formation of melanin.
2. Very effective whitening and freckle removal (when added at 2%).
3. Anti-inflammatory caused by sunlight, with strong antibacterial and anti-inflammatory effects.
4. Improve dull skin and give skin elasticity.
5. Repair skin cell activity and promote collagen production.

Application:
Potassium sodium tartrate tetrahydrate, also known as Rochelle salt, is a double salt of Tartaric Acid first prepared by an apothecary, Pierre Seignette, of La Rochelle, France. Potassium Sodium Tartrate and monopotassium phosphate were the first materials discovered to exhibit piezoelectricity.This property led to its extensive use in "crystal" gramophone pick-ups, microphones and earpieces during the post-World War II consumer electronics boom of the mid-20th Century. Such transducers had an exceptionally high output with typical pick-up cartridge outputs as much as 2 volts or more. Rochelle salt is deliquescent so any transducers based on the material deteriorated if stored in damp conditions.

Butylated Hydroxyanisole
Appearance White powder
Purity 99%
Density 0.9976
Melting point 58-60�ºC
Flash point >230 F
Boiling point 264-270C
Application
Butylated hydroxyanisole is relatively stable to heat and is not easily destroyed under weakly alkaline conditions, so it is a good antioxidant. The antioxidant effect of BHA on animal fats is more effective than on unsaturated vegetable oils. Especially suitable for bakery products using animal fat. BHA has the property of changing color due to interaction with alkaline earth metal ions, so iron and copper containers should be avoided when using it. Mixing chelating citric acid or tartaric acid with this product not only synergizes, but also prevents coloration caused by metal ions. BHA has a certain volatility and can be distilled by water vapor, so it is easily lost in high-temperature products, especially in boiled and fried products. BHA can also be used in food packaging materials.
