Introduction
Homosalate CAS 118-56-9 is an organic compound used in some sunscreens. It is made by the Fischer-Speier esterification of salicylic acid and 3,3,5-trimethylcyclohexanol, the latter being a hydrogenated derivative of isophorone. Contained in 45% of U.S. sunscreens, it is used as a chemical UV filter. The salicylic acid portion of the molecule absorbs ultraviolet rays with a wavelength from 295 nm to 315 nm, protecting the skin from sun damage.

Magnesium Ascorbyl Phosphate is a water-soluble, non-irritating, stable derivative of Vitamin C. It has the same potential as vitamin C to boost skin collagen synthesis but is effective in significantly lower concentrations and can be used at concentrations as low as 10% to suppress melanin formation (in skin-whitening solutions). It is also important to note that Magnesuim Ascorbyl Phosphate may be better choice than Vitamin C for people with sensitive skin and those wishing to avoid any exfoliating effects since many Vitamin C formulas are highly acidic (and therefore produce exfoliating effects).
Magnesium Ascorbyl Phosphate is a very stable vitamin C derivatives (L-Ascorbic acid mono-dihydrogen phosphate magnesium salt) which does not degrade in formulas containing water. In skin care products, Magnesium Ascorbyl Phosphate is used for UV protection and repair, collagen production, skin lightening and brightening, and as an anti-inflammatory. It is also a potent antioxidant.It is considered an excellent non-irritating Sakin whitening agent that inhibits skin cells to produce melanin and lightens age spots, and is a great alternative to Quinone. Magnesium Ascorbyl Phosphate is a also a potent antioxidant that can protect skin from oxidation and UV rays, and is used as an anti-inflammatory(source).It can improve appearance of aged and fragile skin. Widely used as add-on ingredient in skin-lightening products to correct hyperpigmentation and age spots. Antioxidant effect can be increased by combining Magnesium Ascorbyl Phosphate with L-Ascorbic acid and/or vitamin E.

Carboxy Methyl Cellulose ( CMC ) is synthesized by the alkali-catalyzed reaction of cellulose with chloroacetic acid. The polar (organic acid) carboxyl groups render the cellulose soluble and chemically reactive. The functional properties of Fooding Carboxy Methyl Cellulose(CMC) depend on the degree of substitution of the cellulose structure (i.e., how many of the hydroxyl groups have taken part in the substitution reaction), as well as the chain length of the cellulose backbone structure and the degree of clustering of the carboxymethyl substituents.
Used for In vitro diagnostic (IVD) products such as diluent, wash, buffers, and detergents. Broad-spectrum bacteriostatic agents, can effectively inhibit most bacteria and fungi.
