In daily life, shampoo is a necessary product for everyone, but shampooing There are many additives in water that most people don’t know much about. The ingredient list of shampoo is marked according to national standards. In the ingredient list, surfactants, hair conditioners, moisturizers, absorbents, thickeners, solubilizers, and fattening agents are listed. , fragrances, anti-dandruff agents, colorants, preservatives, etc., all use international standard names, and each raw material has its main performance role.
Today I will take you to learn about the two additives in shampoo: solubilizer and pearlescent agent.
Solubilizing agent:
Solubilizing agent (also Referred to as clarifier) refers to a surfactant with solubilizing ability. Solubilization refers to the process in which poorly soluble drugs increase their solubility in solvents and form solutions under the action of surfactants. The function of solubilizer is mainly to improve the solubility of detergent and improve the compatibility of various ingredients. Therefore, the use of solubilizers is very important for both product formulation and use.
Commonly used alcohols such as ethanol, propylene glycol, and glycerin; non-ionic solubilizers such as polyoxyethylene sorbitan monolaurate and polyethylene glycol fatty acid esters; and sodium benzenesulfonate , sodium xylene sulfonate, urea, etc. Fatty alcohol citrate is a new type of solubilizer with excellent properties.
Pearlescent agent:
Pearlescent agent, also called pearlescent flakes. Adding waxy insoluble matter to transparent shampoo and dispersing it can form a shampoo with glitter and pearlescent effect, and can increase the viscosity of the product. It can also moisturize the skin, nourish and protect hair, and have antistatic effects.
Commonly used pearlescent agents include magnesium stearate, lead stearate, magnesium aluminum silicate, and ethylene glycol stearate (generally, monoesters form corrugated pearlescent, while diesters form milky white pearlescent) ), polyethylene glycol stearate, etc. Cetyl alcohol and stearyl alcohol can also be used to prepare pearlescent shampoo.
