1,3-Dihydroxyacetone
1. Basic Product Information
Product Name: 1,3-Dihydroxyacetone
Abbreviation: DHA
CAS Number: 96-26-4
Molecular Formula: C3H6O3
Molecular Weight: 90.08
Synonyms: Dihydroxyacetone, 2-Propanone, 1,3-dihydroxy-
Product Category: Cosmetic self-tanning raw material, food additive, biochemical reagent, fine organic intermediate
2. Physical and Chemical Properties
Physical Indicators
- Appearance: White to off-white crystalline powder
- Odor: Odorless, slightly sweet taste
- Solubility: Freely soluble in water, ethanol, methanol; slightly soluble in acetone; insoluble in oils and aliphatic hydrocarbons
- Melting Point: 89–91 °C
- Density (20 °C): 1.28 g/cm3
- Hygroscopicity: Highly hygroscopic, absorbs moisture rapidly in humid air
- Aqueous Stability: Stable under weak acidic conditions; undergoes Maillard browning reaction with amino substances under neutral/alkaline and heating conditions
Chemical Characteristics
- Molecular Structure: Simple triose ketose with two hydroxyl groups and one ketone group
- Core Functional Mechanism: Reacts with amino acids in stratum corneum to form brown melanoidin pigments, achieving natural sunless tanning effect
- Photostability: Moderately light-sensitive; long-term UV exposure accelerates browning and decomposition
- Thermal Stability: Stable below 70 °C; above melting point, dehydration and discoloration occur
- Chemical Compatibility: Compatible with weak acidic cosmetic buffers; incompatible with high-concentration amino compounds, strong alkalis and heavy metal ions
3. Main Application Fields
- Core Application: Cosmetic Self-Tanning Active Ingredient
Key raw material for sunless tanning lotion, cream, spray and body care products; provides natural bronze skin tone without UV radiation damage - Biochemical Research Reagent
Standard carbon source for microbial culture, enzyme activity and sugar metabolism research - Food Industry Additive
Low-calorie sweetener precursor and food browning auxiliary agent - Pharmaceutical Synthetic Intermediate
Building block for polyhydroxy compound and chiral drug synthesis
4. Platform Category & Product Group Selection Guide
1) Domestic B2B Platform Category
Recommended Path: Other Chemicals / Cosmetic Raw Materials
Reason: Mainly used as cosmetic tanning raw material, also applied in food and biochemistry fields
2) English Product Group Dropdown Options
Recommended Selection: Basic Organic Chemicals
Do NOT select Pharmaceutical Chemicals; it is daily chemical and food raw material instead of human medicine API
3. Standard Foreign Trade Packaging Specification
1kg aluminum foil vacuum bag for cosmetic formula test samples; 25kg fiber drum lined with double PE inner bags for bulk cosmetic factory orders; nitrogen-filled moisture-proof customized packaging available
