Salicylic Acid

1. INCI & CAS

INCI: Salicylic Acid · CAS: 69-72-7

2. Role in the formula

Salicylic acid is restricted by market. This guide uses 0.5% as a cosmetic starting point and does not claim OTC acne treatment, a peel, or a medical indication.

3. Typical use levels (formulation guide)

• The formulation record indicates confirm the market cap for rinse-off clarifiers.
• Leave-on may use the guide range only inside the destination limit, guide start 0.5% in this reference.

Pre-dissolve in a suitable solvent or a hot water phase as the TDS allows. Confirm EU, US and China limits before filing.

4. Regulatory sources & global compliance

• Treat any CosIng entry for Salicylic Acid as a reference only; verify the grade and intended use under current market rules.
• The EU Cosmetics Regulation (EC) No 1223/2009 requires an assessment addressing the safety of the finished product that contains Salicylic Acid before release of the finished cosmetic.
• Review the documentation for the actual Salicylic Acid grade and the filing requirements for the target market.

5. Safety & risk assessment

Read the recorded level as a cosmetic formulation guide; it does not establish drug approval or OTC-monograph status while finished-product patch and stability testing remain necessary.

6. Stability & packaging

Store the bulk in a closed container in a cool, shaded place; review airless or pump options if oxidation presents a concern; check the finished batch's stability and package compatibility.

7. Claims language (Do / Don’t)

• This guide frames Salicylic Acid's cosmetic direction around low-level BHA clarifying.

• The formulation note does not demonstrate drug effects, cures, or certification claims that go beyond the documented ingredient information.
• The documented facts for Salicylic Acid does not demonstrate whitening effects, acne treatment, antiperspirant performance, sunscreen protection, or hair growth.

1. INCI & CAS

INCI: Zinc PCA · CAS: 15454-75-8

2. Role in the formula

Zinc PCA (zinc pidolate) is a water-soluble zinc salt used in cosmetic oil-balance guides. It is not an antibacterial drug claim.

3. Typical use levels (formulation guide)

• For gels and scalp serums, use 0.3–1% for the formula.

Dissolve in water. Check compatibility with anionic thickeners.

4. Regulatory sources & global compliance

• A CosIng entry naming Zinc PCA does not by itself approve the purchased grade or complete cosmetic.
• Regulation (EC) No 1223/2009 sets the requirement for a safety review of the finished cosmetic in which Zinc PCA is used rather than for an ingredient name alone.
• Compare the received Zinc PCA material with its supplier specification and review destination-market filing needs.

5. Safety & risk assessment

This level is a cosmetic-formulation guide; it is not evidence of drug approval or OTC authorization so assess patch response and stability in the final formula.

6. Stability & packaging

Hold the bulk material in a sealed, cool place shielded from light; where appropriate, assess an airless or pump pack for oxidation-sensitive systems; check the finished formula and its packaging together.

7. Claims language (Do / Don’t)

• The recorded cosmetic positioning for Zinc PCA highlights zinc PCA balance.

• The cosmetic listing cannot substantiate therapeutic effects, curative outcomes, or unsupported certification statements.
• This reference for Zinc PCA does not demonstrate whitening, acne treatment, antiperspirant effects, sunscreen use, or hair growth.

1. INCI & CAS

INCI: Glycerin · CAS: 56-81-5

2. Role in the formula

For emulsions, gels, and washes, this guide assigns glycerin a polyol-humectant role. Its level is not a batch assay.

3. Typical use levels (formulation guide)

• Gels and serums: 3–8% for the formula.
• For creams, the recorded level is 2–5% for the formula.
• The guide range for rinse-off is 2–4% in this reference.

Use the water phase to introduce Glycerin; no melting stage is required.

4. Regulatory sources & global compliance

• Use CosIng's information on Glycerin as a reference, then verify the specific grade and intended use under market rules.
• For an EU-market product, Regulation (EC) No 1223/2009 requires a safety assessment of the finished cosmetic containing Glycerin at the level of the finished cosmetic product.
• Review the documentation for the actual Glycerin grade and the filing requirements for the target market.

5. Safety & risk assessment

The use-level note is a reference for cosmetic formulation; it is not evidence of drug approval or OTC authorization with patch assessment and finished-formula stability testing still required.

6. Stability & packaging

Maintain cool, closed, light-protected storage for the bulk material; take oxidation sensitivity into account when selecting the final pack; confirm stability and pack fit with the final formula.

7. Claims language (Do / Don’t)

• The cosmetic formulation concept for Glycerin centers on humectant function.

• The development record is not evidence of drug effects, clinical cures, or unsupported product certifications.
• The Glycerin entry is not evidence for skin whitening, acne treatment, antiperspirant use, sun protection, or hair growth.
