What is Carnitine Hydroxycitrate CAS 499770-48-8?

Carnitine Hydroxycitrate CAS 499770-48-8 is a salt-like active formed from L-carnitine and hydroxycitric acid. It is supplied as a white to off-white crystalline powder and is used mainly in body-sculpting cosmetics, slimming treatments and sebum-control skin care.

What is the INCI name and function of this ingredient?

The INCI name is Carnitine Hydroxycitrate. It combines L-carnitine, which helps transport fatty acids into mitochondria, with the hydroxycitrate fraction, which inhibits fatty-acid synthesis and helps reduce lipid storage in skin treatments.

How is Carnitine Hydroxycitrate used in body-sculpting products?

It is formulated into anti-cellulite creams, slimming gels and body-contouring serums at concentrations often in the 0.5-10% range, with around 2% commonly cited for facial sebum-control use. The ingredient is usually combined with caffeine or other lipolytic actives and incorporated into the aqueous or emulsion phase.

What are the key physical and specification points to confirm before ordering?

Confirm the white to off-white crystalline powder appearance, total assay of at least 98.0%, L-carnitine content about 58.0-62.0%, hydroxycitric acid content about 38.0-42.0%, water solubility, pH of a 5% solution in the 5.5-7.5 range, moisture and particle size.

How should Carnitine Hydroxycitrate be handled and stored?

It is water-soluble but hygroscopic, so keep it in tightly sealed packaging in a cool, dry, well-ventilated area and minimize exposure to humid air. It remains stable in aqueous formulations within a normal cosmetic pH range of about 3-7.

Product Description

Carnitine Hydroxycitrate, CAS 499770-48-8, is a salt-like active formed from L-carnitine and hydroxycitric acid.

Synonyms: Carnitine hydroxycitrate; L-Carnitine hydroxycitrate; 3-carboxy-2-hydroxy-N,N,N-trimethylpropanaminium 3,4-dicarboxy-3,4-dihydroxybutanoate.

CAS: 499770-48-8.

It is a white to off-white crystalline powder with a slight characteristic odor.

It has an assay of not less than 98.0%, with L-carnitine content of about 58.0–62.0% and hydroxycitric acid content of about 38.0–42.0%.

It is soluble in water and has a pH of about 5.5–7.5 in a 5% solution.

It combines L-carnitine, which supports fatty-acid transport, with hydroxycitric acid, which helps inhibit fatty-acid synthesis.

It is used in anti-cellulite creams, slimming gels and body-contouring serums.

It is also used in firming lotions for post-pregnancy and weight-loss skin care.

It is used in topical sports gels to enhance local circulation and metabolism.

It is occasionally used in V-shape face-lifting serums for its tightening properties.

It is typically used at 1.0–5.0% in the water phase of a formulation; facial sebum-control use often cites about 2%.

It is usually combined with caffeine or other lipolytic actives and added to the aqueous or emulsion phase.

Confirm appearance, assay, L-carnitine content, hydroxycitric acid content, solubility, pH, loss on drying, residue on ignition, heavy metals, arsenic, microbial count and particle size.

Store below 25 °C in a cool, dry, dark and well-ventilated area, away from direct sunlight and heat sources.

Keep inner liners tightly sealed, as the powder is hygroscopic and sensitive to humidity.

Confirm packaging with the requested quantity and destination requirements.
