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).

Answer:
D) Tight junctions
Explanation:
Based on the information provided within the question it can be said that the structure that performs this function are known as tight junctions. This structure has two different functions. The first being to limit the passage of molecules and ions through the space between cells, and the second function is that is blocks the movement of important membrane proteins between the epithelial cells
