13.7.3.6 Arabinoxylans in cosmetics

Arabinoxylan derivatives, such as cation arabinoxylans and their hydrophobically modified products, are potentially useful ingredients in cosmetic and personal care products (Yang, Wuxi, & Cui, 2017). Water-soluble cationic arabinoxylans exhibit hair conditioning properties, and arabinoxylans with low-molecular-weight and high charge density can be absorbed on the hair surface. Cationic polymers are commonly used in hair conditioners as the electrostatic interactions between the positively charged cationic polymer and anionic hair surface lead to the absorption of the conditioner on the hair surface, thus making the hair soft and smooth (Fig. 13.18). Properties such as diverse structure, biocompatibility, nontoxicity, and low production costs make arabinoxylans promising candidates for these uses (US patent 2019).

Explanation:

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
