Raw material color issue

one point oneRaw material decolorization issue

1.1.1Activated carbon adsorption method: using the porous structure of activated carbon to adsorb colored impurities, achieving the purpose of decolorization;

1.1.2Ion exchange resin method: using ion exchange to remove colored ions and achieve decolorization.

1.1.3Chemical precipitation method: Separation is achieved by adjusting the acidity and alkalinity to precipitate or change the solubility

one point twoRaw material color protection issue

1.2.1Addition embedding method: using macromolecules such as cyclodextrin and chitosan to embed it, avoiding direct exposure of active groups to air for oxidation and discoloration;

1.2.2Add antioxidants, such as substances that are susceptible to oxidation, and it is recommended to add vitaminsCAnd its derivatives, sulfites, cysteine, etc. prevent it from changing color;

1.2.3Add chelating agents, such asEDTA-2NaSodium hexametaphosphate, pyrophosphate, etc., are color protected by chelating easily oxidizable metal ions;

Solubility/Transdermal issues

   two point oneChemical modification: Chemical modification of raw material molecules by introducing hydrophilic groups to increase their water solubility.e.gEthoxylation modification of natural oils to increase water solubility

   two point twoUse cosolvents: Add some cosolvents to help dissolve the raw materials in water.e.gUsing essential oil ingredients in cosmetic water systems and employing solubilizers

   two point threePreparation of micro lotion or nano lotion: disperse insoluble raw materials in small droplets to form a stable lotion system.e.gOil based vitaminsEThe nanometer lotion is prepared and used in cosmetics water system.

Stability issues

     To prevent oxidation and deterioration of cosmetic ingredients during storage and use, antioxidants or preservatives are often added.e.gVitamins are often added to raw materials containing unsaturated fatty acidsEWaiting for antioxidants. Or molecular structure optimization can be used to improve its stability or efficacy compared to the original sample.e.gAscorbic acid enhances antioxidant activity through etherification protection.

Stimulating issues

   Refining and purifying raw materials to remove impurities that may cause irritation, or using multiple plant compounds to reduce the irritation caused by a certain raw material, can also achieve better synergistic effects; Or use slow-release technology to reduce instantaneous concentration and other methods to reduce irritability;

Odor issue

   Distillation and extraction are used to remove the odor substances in raw materials, and essence can also be added to cover up the bad smell of raw materials.

The issue of raw material functionality and characteristics- Collaborative efficacy

   By compounding multiple components and achieving synergistic effects1+1＞twoThe effect

Purity issue (impurity issue)

   The use of membrane filtration and chromatography techniques for separation and purification can remove impurities and large molecular substances, resulting in purer substances.

The issue of anti-corrosion of raw materials

To prevent microbial growth during storage or use of raw materials, establish corresponding anti-corrosion systems according to the needs of different raw materials.

Issues with raw material standards and specifications

 Gradually establish a raw material safety standard system based on the risk level and frequency of use of cosmetic plant ingredients, and strengthen standard research.
