Cellulose derivatives have the polymeric backbone of cellulose, with repeating anhydroglucose units. After alkaline treatment, cellulose is reacted with methyl chloride to yield methyl ether groups. The end product is purified and ground to a fine powder and is known as methylcellulose.

Due to its chemical and physical uniformity, semi-synthetic polymer Methylcellulose has reproducible properties. It has been helpful in cosmetic formulations as a versatile thickener, gelling agent, and emulsifier with an HLB value of 13.8.

Undecylenoyl Phenylalanine is a substituted amino acid derivative of Phenylalanine and Undecylenic acid. It is a white crystalline powder whose amphiphilic molecular structure provides cutaneous bio affinity.

Boron Nitride (BN) is a chemically stable compound of nitrogen and boron. It has become a popular cosmetic ingredient because of its unique combination of silky feel, skin adhesion, and processability.

Boron Nitride is widely used in decorative cosmetics, including concealers, eye preparations, lipsticks, and skin care products. Therefore, it is beneficial to know how BN's optical properties influence the soft focus effect.

While Benzophenone-type filters have a good absorbance in the UV-B region, they do not block UV-A radiation efficiently. Therefore, a series of Benzotriazole filters for use in personal care products exhibit strong performance over the whole ultraviolet range. Water-soluble Benzotriazoles give better performance versus water-soluble Benzophenones for the stabilization of colors.

Sodium Coco-Sulfate (CFAS) is a naturally derived anionic surfactant produced by sulfating coconut-derived fatty alcohols. As more people become familiar with its unique properties, it is beginning to be used in personal care applications.

Because it is compatible with alkanolamides, betaines, and other anionic surfactants, Sodium Coco-Sulfate can be used in formulations as the primary or secondary surfactant.

Triclocarban (TCC) is an antimicrobial agent with wide activity against Gram-positive bacteria. It is particularly suitable for application in deodorant soaps and other products such as sticks, roll-ons, creams, and lotions when antibacterial activity is required.

Acetyl Hexapeptide-38 is a synthetic peptide (with sequence Ac-Ser-Val-Val-Val-Arg-Thr-NH2) found with screening methods and using the reporter gene assay from millions of other hexapeptides with different sequences. It is also known by the trade-name Adifyline®.
