Problems solved by technology

[0002] At present, anti-dandruff agents commonly used in anti-dandruff shampoos mainly include: zinc pyrithione, campanol, undecylenic acid derivatives, ketoconazole, salicylic acid, etc., among which zinc pyrithione is a highly effective anti-dandruff and anti-dandruff agent. Itching agents and broad-spectrum fungicides are also one of the most widely used anti-dandruff agents at present. However, when they are used in shampoo formulations, they often cause sedimentation, and occasionally discoloration occurs if they are accidentally handled, and they are also prone to discoloration when they encounter iron ions. , Zinc pyrithione is not compatible with disodium edetate, and is unstable to light, which will cover the pearly luster of the shampoo. Its biggest disadvantage is its strong degreasing ability, and long-term use will cause dry hair and other problems
However, the anti-dandruff effect of several other anti-dandruff agents cannot meet the requirements of regulations.
Bipyridinethione, popular in recent years, is effective in killing pityriasis ovale, Bacillus ovale, Candida albicans and other fungi. It is less sensitive to metal ions and has a stable color in the shampoo system. It has better water solubility, which can improve the compounding effect, and its degreasing ability is weak, but the anti-dandruff effect is not ideal

Embodiment I-X

[0072] A suitable method for preparing the anti-dandruff composition described in Examples I-XV is as follows: add an appropriate amount of water into the reaction tank, add guar gum and polyquaternium-10 under slow stirring to disperse, heat to 60°C to 80°C, followed by adding pH adjuster (such as citric acid), ammonium lauryl sulfate, ammonium lauryl polyoxyethylene ether sulfate, cocamidopropyl betaine, fatty acid monoethanolamide, ethylene glycol dishard Sodium fatty acid, acrylic acid copolymer, phthalic acid amide, disodium edetate (if using these substances), let these substances completely disperse and cool down. When the temperature drops to about 70°C, add anti-dandruff agents 1-hydroxy-4-methyl-6-(2,4,4-trimethylpentyl)-2(1H)-pyridone and 1-hydroxy-4 -Methyl-6-(2,4,4-trimethylpentyl)-2(1H)-pyridine ketoethanolamine, after dispersing and dissolving evenly, cool down to below 50°C, add zinc chloride, emulsify silicone oil, stir evenly, Add preservatives, pigments, fl...
