Stearic Acid – Natural Hardening Additive for Candles and Cosmetics

A saturated fatty acid of plant origin (palm, coconut) used as a hardening additive in candles and as an emulsifier in cosmetics. At 2-5% of the wax weight it hardens soft waxes such as soy or coconut, makes unmoulding easier, increases opacity and extends burn time.

Features

• Format: white flakes / beads
• Colour: white
• Origin: plant-based (palm, coconut)
• Melting point: 54-72 ºC depending on grade
• Dosage in candles: 2-5% of total wax weight
• Dosage in cosmetics: 1-25% depending on application
• Storage: cool, dry place

Recommended uses

• Soy wax: 3-5% for firmer moulded candles
• Coconut wax: 2-4% for easier unmoulding
• Soft paraffin: 3-5% to increase hardness
• Vegetable wax blends: 2-5% as needed
• Cosmetics: creams and lotions (2-5%), soaps (1-3%), balms (5-15%) and solid sticks (15-25%)
• For crafters who formulate their own blends and for candle and cosmetics manufacturers

Tips for use

• Work out 2-5% of the wax weight: for 1 kg of soy wax, 30-50 g of stearic acid.
• Add it with the wax when melting and stir until fully incorporated. Then continue as usual (fragrance, pouring...).
• Do not exceed 5%: the candle can become brittle and burn poorly.
• It increases opacity and gives a whiter, matte finish. For translucent candles or bright colours, leave it out or reduce to 1-2%.
• Not recommended in soy container waxes already formulated to adhere to glass, as it can cause pull-away and cracks.
• For cosmetic use, check that the grade is suitable for that application.
