General Description
FINECHEMO DSTB, chemically known as Borax (Sodium Tetraborate Decahydrate), is an inorganic salt widely used in cosmetic and personal care products as a pH buffer, emulsifier, and preservative booster. It is valued for its ability to stabilize emulsions and enhance the efficacy of preservatives when used in combination with other ingredients. As a multifunctional additive, FINECHEMO DSTB supports formulation consistency and shelf life, particularly in creams, lotions, and other emulsion-based systems.
Uses in the Cosmetics Industry
FINECHEMO DSTB is utilized in a range of cosmetic applications due to its versatile functionality:
- Acts as an emulsification aid, helping oil and water components blend smoothly.
- Helps maintain formulation pH and contributes to mild cleansing performance.
- Enhances the activity of certain preservatives, especially in aqueous systems.
- Used in bath salts and soaks to soften water and stabilize product composition.
- Contributes to formulation stability and viscosity control.
It is commonly used at low concentrations and often purchased in bulk for industrial-scale cosmetic manufacturing due to its cost-effectiveness and multifunctionality.
Hazards
While FINECHEMO DSTB is effective in cosmetic formulations, its use must comply with safety guidelines due to potential hazards:
- May cause mild irritation on prolonged or concentrated exposure; should be used within safe concentration limits.
- Dust inhalation can irritate respiratory pathways; protective equipment is advised during handling.
- Borax has been associated with reproductive toxicity in high doses; its use in cosmetics is restricted or regulated in some regions (e.g., EU).
- Can accumulate in the environment; proper disposal practices should be followed.
Regulatory authorities like the EU and FDA provide guidelines on permissible levels in finished products. It should be handled with care and used in accordance with regional regulations.
Storage & Stability
- Keep in a tightly sealed container in a cool, dry area away from moisture.
- Chemically stable under normal storage conditions and compatible with various emulsifiers and actives.
FINECHEMO DSTB is available for wholesale and bulk purchase, ideal for formulators needing a stable, multi-functional ingredient for emulsification and preservation support in personal care products.
CAS Number: 1303-96-4
INCI: Disodium Tetraborate Decahydrate
Composition: FINECHEMO DSTB is composed of disodium tetraborate decahydrate, commonly known as borax. It consists of sodium, boron, oxygen, and water molecules and is widely used as a buffering agent, emulsifier, and viscosity modifier in cosmetic and industrial formulations.
Purity Grade: Technical or Cosmetic Grade (typically ≥ 99% as Na₂B₄O₇·10H₂O)
Appearance: White crystalline powder or granules
Solubility: Soluble in water; forms an alkaline solution. Insoluble in alcohol.
Preservation: Not applicable; chemically stable and does not require preservation.
Storage: Store in a tightly sealed container in a cool, dry, well-ventilated area. Avoid exposure to humidity and moisture to maintain its crystalline structure.
Raw Material Sources: Mined from naturally occurring borate mineral deposits such as tincal or kernite; also refined from brine or lake deposits rich in borates.
Manufacture: Produced by mining borate ores followed by refining and crystallization processes to isolate and purify disodium tetraborate decahydrate.
Animal Testing: Not animal tested
GMO: GMO-free (inorganic compound; not plant-derived)
Vegan: Does not contain animal-derived ingredients
Proposition: FINECHEMO DSTB complies with applicable industrial and cosmetic-grade standards. Note: Borax is restricted or banned in leave-on cosmetics in some jurisdictions (e.g., EU) due to concerns about reproductive toxicity. Compliance must be assessed based on product type and market regulations.
Warning: For external use only. Avoid inhalation of dust and contact with eyes or broken skin. May cause irritation with prolonged exposure. Use protective equipment during handling. Not recommended for use in products intended for children or pregnant individuals.
