Natural hydrocolloid gelling agent for clear, firm water gels; dissolves at 90–95°C and sets on cooling. Typical use 0.2–1.5%.
Agar Agar (Strip) is a cosmetic‑grade hydrocolloid gelling agent derived from red seaweed (agarose/agalactan polysaccharide). It builds clear, firm water gels and stabilizes suspensions in skincare.
It dissolves only when heated to about 90–95°C and forms a thermo‑reversible gel as it cools (typically sets around 35–45°C). Compared with xanthan or carrageenan, agar gives a high‑clarity, rigid gel; blending small amounts of xanthan improves elasticity and reduces syneresis.
Gel strength decreases with strong acids and high electrolytes; short exposure to alcohol (≤20%) is tolerated. Use humectants to tune texture and water retention.
Product Description: Natural polysaccharide (agarose‑rich) that builds clear, brittle water gels with excellent shape retention. Suitable for gel masks, jelly toners/serums, and rigid gel textures. Thermo‑reversible; reheating above the melt point liquefies the gel.
Usage: Gel masks, jelly toners/serums, rinse‑off jelly cleansers, anhydrous‑in‑water gel suspensions, bead/jelly in jar formats.
Mixing method:
- Premix the powder/strips with glycerin (1:3–1:5) to aid dispersion.
- Disperse into deionized water and heat to 90–95°C with stirring until fully dissolved and clear (hold 5–10 minutes).
- Cool with gentle stirring; add heat‑sensitive ingredients below 40°C. Agar gels on cooling; package before full set if a pourable texture is required.
- pH 4–10 is generally suitable. Strong acids/electrolytes reduce gel strength; ethanol ≤20% is typically acceptable.
Usage rate: 0.2–1.5% (up to 2% for very firm gels)
Product characteristics: Off‑white to pale‑yellow strips or powder; characteristic odor; forms clear, firm water gels on cooling.
Solubility: Insoluble in cold water and oils; dissolves in hot water (~90–95°C) and gels on cooling; not soluble in ethanol; dispersible with polyols.
