Applications
Cosmetics and Personal Care
- Depilatory Creams and Lotions: Incorporated at 3-8% as the active reducing agent to dissolve hair shafts in 5-10 minutes, ideal for facial and body hair removal with minimal residue.
- Hair Straightening and Perming: Used at 2-5% in neutralizers and wave sets to reform disulfide bonds, achieving smooth, long-lasting results in professional salon treatments.
- Tonics and Dressings: Stabilizer in non-coloring hair products for enhanced conditioning and manageability without altering texture.
Industrial and Pharmaceutical Uses
- Reducing Agent in Formulations: Chelates heavy metals in topical preparations, improving stability and shelf life.
- Microbiological Media: Component in anaerobic culture media for bacterial growth promotion due to its thiol content.

Frequently Asked Questions (FAQs)
What is Calcium Thioglycollate?
Calcium Thioglycollate is the calcium salt of thioglycolic acid with formula C₄H₆CaO₄S₂ and CAS 814-71-1, functioning as a reducing agent in cosmetics. It’s a white, water-soluble powder that weakens hair keratin for depilatory and hair reshaping applications.
How is Calcium Thioglycollate used in depilatory products?
Blend at 4-6% into cream bases with alkaline activators; apply for 5-15 minutes to break disulfide bonds, then rinse for smooth results. Patch testing is recommended for sensitive skin compatibility.
Is Calcium Thioglycollate safe for cosmetic use?
Yes, it’s CIR-approved for rinse-off products up to 10%, with low irritation potential and no systemic toxicity at typical concentrations, though eye contact should be avoided.
What is the shelf life of Calcium Thioglycollate?
In tightly sealed containers stored cool and dry (<15°C), it remains stable for 2-3 years, protected from oxidation and moisture to preserve reducing potency.
Can Calcium Thioglycollate be combined with other actives?
It pairs well with urea or hydroxyethyl cellulose for enhanced viscosity but avoid strong oxidants; stability tests confirm synergy in alkaline pH environments.
Does Calcium Thioglycollate have an odor?
Our high-purity grade is virtually odorless, eliminating the mercaptan smell common in thioglycolic acid derivatives for a more pleasant user experience.
What packaging options are available for Calcium Thioglycollate?
Standard options include 25kg multi-layer paper drums and 50kg plastic-lined cartons, all desiccated and suitable for air/sea freight compliance.
