Final answer:
The correct examples of conditioning agents found in shampoos are silicones and polyquaternium compounds. Silicones provide slip and shine, whereas polyquaterniums help to neutralize static and improve hair texture.
Step-by-step explanation:
Two examples of conditioning agents that boost shampoos are b) Silicones and polyquaternium compounds. These ingredients are added to shampoos to enhance their conditioning properties. Silicones are synthetic ingredients that provide slip and shine, helping to detangle and smooth the hair cuticle.
Polyquaternium compounds are a family of polymers that positively charge ions to neutralize the negative charges on hair strands, thereby reducing static and enhancing the feel, appearance, and manageability of hair.
On the other hand, sodium chloride (salt) and citric acid are generally used to adjust shampoo's viscosity and pH balance, respectively, but are not primarily conditioning agents. Ethanol and hydrogen peroxide are used in personal care products but not typically for conditioning purposes in shampoo formulations. Zinc oxide and glycerin can be found in skincare products, and while glycerin has moisturizing properties, it is not commonly used for its conditioning benefits in shampoos.
