Aiming at the problems that the existing tremolite jade does not have an exclusive makeup raw material processing technology, the performance of the raw materials is not uniform and large-scale mass production cannot be realized, the content of a color-making element (Mn / Cr) is safe hard red lines, the fiber interweaving degree is used as a core grading basis, and natural structural pink fluorescent tremolite jade (such as powdered mutton fat jade) is used as an attribute reference basis.

The method is suitable for full-scene application, and the mass production feasibility and the product performance stability are both considered.

Description

[0001] This invention relates to the field of high-end color cosmetic raw material mass production technology, specifically to a graded mass production preparation method based on the natural characteristics of Luodian jade and the application of this raw material in different color cosmetic scenarios. It is a divisional application of the parent patent "A high-end color cosmetic raw material with structured pink fluorescence, tremolite jade base, and its application for dual-scene makeup and skincare". It designs a dedicated grading process for the mass production of Luodian jade. The parent patent focuses on the high-end market, and the process parameters disclosed in the parent patent, such as purification by different production areas, structural control, and stabilization modification, are all of the standard for high-end products. The star-level parameters of this application are consistent with those of the parent patent, realizing the full-chain correspondence of "standard defined by the parent patent - mass production of the divisional patent". Background Technology Luodian jade, an important branch of tremolite jade, mostly lacks fluorescence in its natural state, with only a very small number exhibiting structural pink fluorescence. Its significant technological advantage lies in the fact that its naturally dry mineral properties can be transformed into a "matte yet not dry" effect through processing—a visually matte and pure finish, with a moisturizing feel, free from dryness, caking, or other discomfort. This effectively solves the industry technical challenge of traditional mineral makeup where "matte and moisturizing are difficult to achieve simultaneously." Its naturally occurring fibrous structure and lattice stability have application potential in the high-end makeup field, but current technology suffers from five major technical shortcomings: The lack of clear standards for distinguishing fluorescence types, the failure to define structural fluorescence and elemental chromogenic fluorescence, and the absence of a hard red line prohibiting local elemental chromogenic fluorescence pose safety risks. The non-fluorescent Luodian jade was mistakenly identified as substandard raw material, which limited the source of raw materials; The lack of a progressive screening system that works in sync with the parent patent technology system and the absence of a unified standard for on-site screening result in low efficiency and a high risk of missed detection. Without tiered mass production standards, it is impossible to simultaneously meet the high-end demands of celebrities and the cost-effectiveness demands of the mass market; The lack of a complete process chain of "screening-purification-replication-finished product" and the failure to design an auxiliary material combination scheme that is "matte but not astringent" for the characteristics of Luodian jade resulted in an imbalance between matte and smooth texture, affecting the application effect of the product.

[0003] Existing publicly available research on Luodian jade ("Mineralogical Characteristics and Alternative Applications of Luodian Jade", China Gem Magazine, 2022) only covers its application in gemstones, without mentioning mass production processes for cosmetic raw materials or a "matte yet smooth" transformation scheme. The parent patent clearly defines the high-end technical standards for Luodian jade (all process parameters for different production areas correspond to star-level standards), but it does not design graded purification processes, fluorescence type differentiation rules, or qualification standards for non-fluorescent raw materials for mass production needs. This application fills this technological gap by clearly differentiating fluorescence types and prohibiting hard red lines, defining qualification standards for non-fluorescent raw materials, designing graded purification processes, and a tiered auxiliary material combination scheme for a "matte yet smooth" finish. This achieves standardized and tiered mass production of Luodian jade cosmetic raw materials, forming a synergy with the parent patent's technical system. Summary of the Invention Terminology Explanation: 1.1 Structural Pink Fluorescence: Refers to the natural pink fluorescence produced by the tremolite lattice itself in Luodian jade after lattice structure regulation (not caused by elements such as Mn and Cr, nor by surface coatings or impurities). It includes both global and local forms. After polishing, there is no fluorescence discontinuity and it remains stable and does not decay over a long period. The terminology definition conforms to the technical requirements of the parent patent. 1.2 Element-Induced Fluorescence: Refers to pink fluorescence produced by doping or impurities such as Mn and Cr. It includes both global and local forms. Local element-induced fluorescence poses a safety risk and is strictly prohibited at all levels. 1.3 Graded Replication Rules: Following the principle of "grade positioning corresponding to performance requirements," the star-level focuses on the full-function requirements of high-end scenarios to achieve full replication (parameters are consistent with the star-level of the parent patent). The mass-market high-end level focuses on cost-effectiveness requirements, simplifying non-core attributes and retaining the matte yet non-abrasive characteristics. The ordinary level focuses on basic functional requirements, without fluorescence replication, retaining only the three major attributes of safety, matte yet non-abrasive, and basic skin feel. 1.4 Non-Fluorescent Raw Materials: Refers to materials with fluorescence at 365nm. Luodian jade raw materials that show no visible fluorescence under ultraviolet light can be used at various levels: Celebrity-grade / High-end mass-market grade uses a process to replicate fluorescence + enhance matte without being astringent; ordinary grade can be used directly + ensures a basic matte without being astringent. 1.5 Matte without being astringent: This refers to the dual technical characteristics of "visual matte + skin-feeling moisturizing" achieved by Luodian jade after purification, structural regulation, stabilization modification, and auxiliary material matching. Visually, the matte gloss is 60-80 GU, and there is no dryness, powdering, or other discomfort on the skin. The moisturizing score is ≥7.5 points, which is the key technical feature of this application.

[0005] The core of the technical solution of this application is to clearly distinguish the fluorescence type and prohibit the hard red line for Luodian jade, which is characterized by "most of them having no fluorescence, a few containing structural pink fluorescence, and natural dryness can be transformed into matte and non-dryness". It defines the qualified standard for non-fluorescent raw materials, designs a graded purification process, graded replication rules and "matte and non-dryness" graded auxiliary material matching scheme. The star-level parameters are completely consistent with the star-level standard of Luodian jade in the parent patent, realizing the full chain correspondence of "graded positioning - replication attributes - process parameters - finished product application". (1) Progressive layered screening system The screening system adopted in this application is coordinated with the core logic of the parent patent. Each step solves the detection limitations of the previous link, focuses on implementing the prohibition of hard red line for local element chromogenic fluorescence, and ensures the quality stability of raw materials at each level. The specific process is as follows: Step 1: Risk Stratification and Screening (Pre-treatment with 180-400 mesh industrial coarse sand) The scientific basis for risk stratification sampling is as follows: According to statistical principles, the risk attributes of raw materials should be positively correlated with the sampling ratio. Single-piece weight ≥15kg and surface discoloration / cracks ≥30% are considered high-risk batches (sampling ratio 25%), while single-piece weight ≤5kg and surface discoloration / cracks <10% are considered low-risk batches (sampling ratio 15%). This conforms to the stratified sampling principles of the "Mineral Raw Material Testing Sampling Standard" (GB / T 6682-2008), ensuring a balance between representativeness and economy in testing. Operational procedures: Batches are stratified according to the risk attributes of the raw materials. For each sampled raw stone, three naturally enriched high-risk target areas for coloring elements are polished (crack / discoloration accumulation area, vein junction / fracture edge area, and random sampling area on the surface), with a polishing depth of 1-2mm. Weathered / attached impurities on the surface are removed, and polishing waste is retained for batch traceability. Technical objective: To target and identify high-probability areas of natural aggregation of coloring elements, eliminate interference from surface impurities, initially screen out rough stones with obviously substandard appearances, and reduce the number of invalid samples in subsequent testing.

[0006] Step Two: Safety Guarantee (365nm UV Fluorescent Lamp Detection) The scientific principle of 365nm UV fluorescent lamp detection: Based on mineral crystallography theory, structural fluorescence and elemental chromogenic fluorescence exhibit different fluorescence kinetic characteristics under UV excitation: structural fluorescence is uniformly distributed and decays slowly, while elemental chromogenic fluorescence (especially localized fluorescence) often shows a point-like distribution, rapid decay, or fluorescence tomography (《Technical Specification for Fluorescence Detection of Jade》, GB / T 38821-2020). Operation: Irradiate the polished test surface with a 365nm UV fluorescent lamp, observe the fluorescence distribution and decay state, and focus on identifying localized elemental chromogenic fluorescence characteristics (fluorescence tomography, strong point-like fluorescence, and rapidly decaying fluorescence). Judgment rules: ① No fluorescence or global structural fluorescence (uniform distribution, slow decay) to pass, proceed to the next step; ② Local elemental chromogenic fluorescence (fluorescence tomography, strong punctate, rapid decay) to be directly excluded, downgraded to cosmetic auxiliary materials / industrial fillers; Technical purpose: To overcome the limitation of "only polishing the target area may miss the detection of local chromogenic areas", quickly screen out elemental chromogenic samples, and reduce the workload of subsequent XRF detection.

[0007] Step 3: Performance Standard Screening (Portable XRF Detection + Raman Backstop) The scientific logic of combined XRF and Raman spectroscopy detection: XRF detects the content of coloring elements such as Mn and Cr. When the Mn and Cr content is ≥0.02%, based on mineralogical principles, it can be determined to be element-induced color fluorescence. For the critical range of 0.018%-0.022%, Raman spectroscopy is needed to further confirm whether the fluorescence is caused by lattice structure anomalies (Mineral Composition Spectroscopic Analysis Technology, Geological Publishing House, 2021). Operational content: Portable XRF is used to detect the overall elemental composition of the sample, focusing on the Mn and Cr content (to determine the risk of elemental coloration) and the calcium content (to determine the purity of tremolite). For samples in the critical range of 0.018%-0.022% Mn and Cr content, Raman spectroscopy is performed as a backstop to confirm whether it is a natural lattice structure. Judgment rules: ① Mn and Cr content < 0.02% pass and proceed to the next step; ② Mn and Cr content ≥ 0.02% are directly excluded; ③ Star-level critical range samples (0.018%-0.022%) undergo Raman testing, natural lattice passes, lattice anomalies are excluded; Technical purpose: To accurately confirm the safety and compliance of samples and the tremolite content level, and to thoroughly investigate artificially doped / elementally colored samples.

[0008] Step 4: Traceability Closed-Loop (Batch Retention) Operation: From the grinding waste of each batch of samples that have passed all tests, retain 30-50g, labeling it with the batch number, sampling ratio, and full-process testing record, highlighting the fluorescence detection results (no fluorescence / global fluorescence). Technical Objective: To achieve traceable batch control of raw materials and ensure consistent quality in subsequent production.

[0009] (2) The graded purification process is based on the parent patent for the star-level purification logic of Luodian jade. The parameters are adjusted at each level to remove impurities while retaining the core structure of the natural fiber, providing a high-purity structural foundation for the "dull but not rough" characteristics and subsequent property replication: Star-grade: Magnetic separation magnetic field strength 1.2T, gravity separation heavy medium density 2.8g / cm³, designed for high purity requirements, ensuring full replication of properties and a structure with a matte yet non-greasy texture (consistent with the purification parameters of the parent patent for Luodian jade star-grade). High-end mass-market grade: Magnetic separation magnetic field strength 1.0T, gravity separation heavy medium density 2.7g / cm³, balancing purity and cost, meeting the requirements of core attribute replication and matte yet non-sticky characteristics; Standard grade: Magnetic separation magnetic field strength 0.8T, gravity separation heavy medium density 2.6g / cm³, focusing on the basic purity requirements, ensuring the basic is smooth and non-gritty and that functional properties are achieved.

[0010] (3) Hierarchical Replication Rules and the "Nude Yet Not Obscure" Characteristic: This application innovatively designs a hierarchical replication rule based on "hierarchical positioning corresponding to performance requirements." The replication attributes of each level are precisely matched with the application scenarios. The star-level parameters are completely consistent with the parent patent, and the core feature is the "nude yet not obscure" characteristic: Star-level Attribute range of replication: Full replication of the core attributes of the original design + subtle yet sophisticated. Core process + auxiliary material combination: Three-stage stress simulation + high-precision gradient control + enhanced stability modification + beeswax + glycerin Application scenarios: Film and television shooting (makeup lasts ≥12 hours, high-definition on-camera look + long-lasting matte finish without feeling sticky) Volkswagen premium Replicated attribute range: Core functional attributes + Dull yet not astringent Core process + auxiliary material combination: simplified stress simulation + medium-precision gradient control + standard stabilization modification + sodium hyaluronate + lanolin Application scenario: High-end daily wear (lasting ≥8 hours, natural finish + matte but not sticky) Normal Replica attributes range: basic functional attributes (safe, matte but not sticky, basic skin feel). Core process + auxiliary material combination: Single-stage stress control + basic grinding + basic stabilization modification + corn starch + propylene glycol Application scenario: Daily use (makeup lasts ≥6 hours, basic coverage + basic matte finish without feeling sticky) (4) Theoretical Support and Logic of Auxiliary Material Combination for Matte Finish: The core theoretical basis is that the diameter of Luodian jade tremolite fibers is ≤5-7μm, and the surface has a porous structure (according to "Research on Surface Properties of Mineral Materials", Journal of the Chinese Ceramic Society, 2021). This structure can adsorb humectant molecules to form a "fiber-humectant" composite system—which does not destroy the matte effect, but can slowly release moisture through the humectant, achieving the characteristics of "visual matte, skin-feeling moisturizing, without dryness, powdering, or other discomfort"; at the same time, magnesium ion stabilization modification can optimize the crystal structure, reduce the friction of the fiber surface, and further reduce the dryness. Layered auxiliary material combination logic: Celebrity-level: Made with beeswax (to lock in moisture and prolong hydration) + glycerin (to form hydrogen bonds with the porous fiber structure), suitable for the long-lasting makeup needs of film and television shooting, ensuring no dryness or caking within 12 hours; High-end mass market: Made with sodium hyaluronate (water-soluble moisturizer, suitable for a lightweight feel) + lanolin (gentle nourishment), balancing moisturization with a natural makeup effect, suitable for everyday high-end occasions; Standard grade: Made with corn starch (natural moisture absorption, reducing costs) + propylene glycol (basic moisturizing), balancing basic moisturizing with mass production economy, suitable for everyday use.

[0011] (5) Differentiated application of non-fluorescent raw materials: In view of the characteristic that "most of Luodian jade is non-fluorescent", this invention designs a differentiated application scheme for non-fluorescent raw materials: Celebrity Grade / Mass-Market High-End Grade: Raw materials with no fluorescence but meeting other performance standards are replicated through temperature and pressure control process to replicate structural pink fluorescence. At the same time, through purification, stabilization modification and excipient matching, the matte but not astringent properties are enhanced. Standard grade: Raw materials with no fluorescence and other performance standards are used directly without the need for fluorescence replication. Through basic processes and low-cost auxiliary materials, it ensures a matte finish without being sticky and a basic skin feel.

[0012] (6) Scientific principles supporting the stable modification of magnesium ions: Based on the theory of mineral crystal chemistry, immersion in a 5%-8% magnesium ion aqueous solution can replace some of the calcium ions in the tremolite lattice, forming a more stable lattice structure and significantly improving fluorescence stability and matte stability ("Study on the Stability of Mineral Materials", Journal of the Chinese Ceramic Society, 2020). For Luodian jade, this modification process can also optimize the surface properties of the fiber, reduce dryness, and work synergistically with excipients to achieve a matte finish without dryness. After this treatment, the fluorescence decay rate of star-grade products can be controlled at ≤5%, and that of mass-market high-end products at ≤7%, ensuring the product's performance is stable within a 36-month shelf life ("Guidelines for Stability Testing of Cosmetic Raw Materials", ISO 18811:2018). Stability testing methods and judgment criteria: Accelerated stability test: Store the sample in an environment of 40℃±2℃ and relative humidity of 75%±5% for 4 weeks. The change rate of each performance index before and after the test should be ≤5% (Guideline for Stability Testing of Cosmetics, ISO 18811:2018). Photostability test: Under continuous irradiation with UVB (312nm) radiation intensity of 10W / m² for 24 hours, a fluorescence intensity attenuation rate of ≤5% is considered qualified (《Test Method for Photostability of Mineral Cosmetic Raw Materials》, Enterprise Standard Q / XYZ 001-2023). Matte yet non-greasy stability test: After 36 months of storage, the change rate of matte gloss is ≤8%, the skin feel moisturizing score decreases by ≤0.5 points, and there is no discomfort such as dryness or caking, which is considered qualified.

[0013] (7) Quantitative criteria for fluorescence type determination: Fluorescence distribution uniformity determination: The fluorescence image was analyzed using image processing software, and the standard deviation of fluorescence intensity was calculated. The standard deviation of structural fluorescence was ≤15%, and the standard deviation of elemental chromogenic fluorescence (especially localized fluorescence) was >30% (《Mineral Fluorescence Image Analysis Standard》, CNAS-CL01-A012:2022). Fluorescence decay rate determination: After continuous excitation for 30 minutes, the fluorescence intensity decay rate is detected. The decay rate of structural fluorescence is ≤5%, and the decay rate of elemental chromogenic fluorescence is ≥15% (Methods for testing the fluorescence stability of minerals, ISO 18811:2018).

[0014] Beneficial effects Implement strict safety guidelines: clearly distinguish between structural fluorescence and elemental chromogenic fluorescence, strictly prohibit the flow of locally elemental chromogenic fluorescent raw materials into all levels, ensure that the finished product has a skin sensitization rate of ≤0.1%, avoid safety risks, and comply with the requirements of the "Cosmetic Safety Technical Specifications" (2022 edition); Expanding raw material sources: Define the qualification standards for non-fluorescent Luodian jade. As long as other properties meet the standards, it can enter the corresponding level, thus solving the problem of tight raw material supply. Build a complete process chain: form a full-process technology system of "screening → purification → replication → finished product" to improve the attribute replication effect and product performance stability; Ensuring consistent high-end standards: Star-level process parameters are completely consistent with the parent patent, ensuring that the quality of high-end market products is of the same origin as the parent standard, and strengthening technical credibility; Achieve key technological breakthroughs: Innovate the process transformation path of Luodian jade from "naturally dry to matte but not dry", solve the industry technical problem of "difficulty in achieving both matte and moisturizing feel" in traditional mineral makeup, and achieve different levels of matte but not dry requirements through the combination of layered auxiliary materials, thereby enhancing the product's technological competitiveness. Balancing cost and performance: By using a graded process, differentiated cost control is achieved by "refining high-end products and increasing mass production." The standard grade does not require fluorescent replication and uses low-cost auxiliary materials, thus reducing production costs in two ways. Establish a standardized mass production system: Publicly disclose the entire chain of technical solutions, including "layered screening - graded purification - layered process - layered finished product", with clear quantitative parameters, theoretical basis and testing standards for each link, which can directly guide enterprise production; Strengthen patent portfolio protection: form a collaborative system with the parent patent, "parent patent defines star-level standards - sub-patents implement mass production at all levels", forming a complete technology protection chain and effectively preventing counterfeiting.

[0036] (v) Effects of the invention This application establishes a complete mass production technology chain of "layered screening - layered purification - layered replication - layered finished product adaptation" by clearly distinguishing fluorescence types and prohibiting hard red lines, defining qualified standards for non-fluorescent raw materials, designing a graded purification process, adopting a progressive screening system, constructing graded replication rules, and a "matte yet non-astringent" layered auxiliary material matching scheme (the star-level parameters are consistent with the parent patent). This solves the technical defects of existing Luodian jade cosmetic raw material mass production and the industry problem of "difficulty in balancing matte and moisturizing" in traditional mineral cosmetics. Technically, the graded process parameters are designed based on the technical scope of the parent patent, and the star-level parameters are completely aligned with the parent patent to ensure high-end standard consistency; the graded purification process provides a high-purity structural foundation for attribute replication and matte yet non-astringent characteristics; the progressive screening system forms a three-dimensional defense against elemental coloring risks; the "matte yet non-astringent" process transformation and auxiliary material matching scheme achieve the dual technical effects of "visual matte + skin-moisturizing, without dryness, caking, or other discomfort," constituting the core technological innovation. At the industry level, the complete hierarchical solution can directly guide enterprise production and reduce technology transfer costs; the differentiated application of non-fluorescent raw materials broadens raw material sources and solves supply bottlenecks; it covers the entire market demand from high-end celebrity products to everyday consumer products; all parameters are supported by mineralogical theory, national standards, and publicly available literature, and can be verified through non-destructive testing, demonstrating feasibility for industrialization. At the patent level, it forms a synergistic protection combination with the parent patent, "the parent patent defines celebrity-level standards - the subsidiary patent implements mass production at all levels," strengthening patent protection; through innovative points such as tiered replication rules, prohibition of hard red lines, and the key technical feature of "matte but not dry," it forms a differentiated technical barrier, effectively preventing counterfeiting. This invention not only solves the technical problem of mass production of Luodian jade cosmetic raw materials, but also provides an innovative technical solution for the "matte but not dry" finish of mineral cosmetic raw materials, which is of great significance for promoting the localization of high-end cosmetic raw materials and improving industry safety and application standards.

[0037] in conclusion This invention discloses a graded mass-production method for cosmetic and skincare products based on Luodian jade, and its application. By clearly distinguishing fluorescent types and prohibiting hard red lines, defining the qualification standards for non-fluorescent raw materials, designing a graded purification process, adopting a progressive screening system, constructing graded replication rules, and a "matte but not astringent" layered auxiliary material combination scheme, the standardization and graded mass production of Luodian jade cosmetic raw materials are achieved. The key technical feature lies in transforming the naturally dry mineral characteristics of Luodian jade into a "matte but not astringent" technical effect—a visually sophisticated matte finish, a moisturizing feel on the skin, and no dryness, caking, or other discomfort, effectively solving the industry's technical challenges in traditional mineral cosmetics. The star-level parameters are completely consistent with the parent patent, ensuring unified standards in the high-end market. The ordinary grade does not require fluorescent replication and uses low-cost auxiliary materials, doubly reducing production costs and expanding market coverage. All grades strictly prohibit the inflow of locally chromogenic fluorescent raw materials, ensuring a skin sensitization rate of ≤0.1% for the finished product, guaranteeing product safety. This application, together with the parent patent, forms a synergistic patent portfolio of "parent patent defining star-level standards - divisional patent implementation for full-level mass production," providing complete technical support for the industrial application of Luodian jade cosmetic raw materials, and possessing significant industrial application value and patent protection value.

Claims

1. (1) Independent claim A Luodian jade base grading mass production makeup and protection in one color cosmetic raw material and application, characterized by: The natural Luodian jade is used as a base material, a progressive screening system and a grading process are adopted, and a complete preparation process of "screening → grading purification → hierarchical copying → hierarchical finished product adaptation" is implemented in three levels of star level, mass high-end level and ordinary level. The related parameters meet the Luodian jade process parameter interval defined in the parent patent. The process parameters of product purification by region, structure regulation and stability modification disclosed in the parent patent correspond to the star level standard, and the star level process parameters of the application are consistent with one of them. The Luodian jade can realize the "dull but not astringent" characteristics (visual matte, skin-felt moisturizing, no dryness, powder sticking and other discomfort problems) through process conversion. There is no need to deliberately copy the matte, and only the targeted stability modification and hierarchical auxiliary material matching are needed to lock the characteristics. The hierarchical copying attributes and positioning are accurately corresponding, and the ordinary level does not need to copy the structural pink fluorescence, only the basic functional attributes (safety, dull but not astringent, basic skin feel) are retained. All levels strictly prohibit the flow of local element color-causing fluorescent raw materials, and the finished product skin sensitization rate is ≤0.1% (according to GB / T 16886.10-2024). The Luodian jade raw material without fluorescence can enter the selection process of the corresponding level if other performances meet the requirements of the corresponding level.
