What changed
Insoluble impurities testing is now required for cosmetic oils and fats (DEAS 847-3: 2025).
Glossary of terms updated to standardize industry terminology (DEAS 847-1: 2025, DEAS 846: 2025).
Acid value and free fatty acids must be measured using new standardized methods (DEAS 847-4: 2025).
Moisture and volatile matter content must be tested via new method (DEAS 847-2: 2025).
Who it affects
Cosmetic manufacturers must test for impurities, moisture, and acidity using DEAS 2025 methods.
Testing laboratories must adopt the new analytical standards for product evaluation.

Compliance Answer: Updated Analytical Standards for Cosmetics and Oils in Kenya
Kenya enforces updated analytical standards for cosmetics and oils under the East African Standards (EAS) 847 series, which prescribe standardized testing procedures for parameters such as insoluble impurities, moisture content, acid value, and free fatty acids. These standards are harmonized across the East African Community (EAC) and are legally applicable in Kenya through the East African Standards Committee (EASC) framework1.
Regulation Analysis
The EAS 847 series comprises multiple parts, each detailing specific analytical methods for oils and fats used in cosmetics. Below is a summary of the key requirements for the parameters mentioned in the user’s question:
| Parameter | Key Requirement | Applicable Standard | Authority |
|---|---|---|---|
| Insoluble Impurities | The test method involves dissolving the material in isopropyl alcohol, filtering the solution, and washing the residue with petroleum ether. The insoluble impurities are quantified by weighing the dried residue2. | DEAS 847-3: 2025 | EASC/TC 0712 |
| Moisture Content & Volatile Matter | A known mass of the sample is evaporated to constant weight, and the moisture/volatile matter content is calculated as a percentage of the original sample mass3. | DEAS 847-2: 2025 | EASC/TC 0713 |
| Acid Value & Free Fatty Acids | The acid value is determined by titrating the material in an alcoholic medium (e.g., ethanol) with aqueous sodium or potassium hydroxide. Free fatty acids are calculated as oleic, lauric, ricinoleic, or palmitic acids4. | DEAS 847-4: 2025 | EASC/TC 0714 |
| Glossary of Terms | Defines key terms (e.g., acid value, free fatty acids) to ensure consistent interpretation of analytical methods5. | DEAS 847-1: 2025 / DEAS 846: 2025 | EASC/TC 0711, 5 |
Detailed Requirements by Parameter
1. Insoluble Impurities (DEAS 847-3: 2025)
- Scope: Applies to oils and fats used in cosmetics2.
- Test Method:
- Dissolve the sample in isopropyl alcohol.
- Filter the solution through a dried, pre-weighed filter paper.
- Wash the residue with petroleum ether and dry to constant weight.
- Calculate insoluble impurities as a percentage of the original sample mass2.
- Normative Reference: EAS 847-1 (Glossary of terms)2.
2. Moisture Content and Volatile Matter (DEAS 847-2: 2025)
- Scope: Applies to oils for cosmetic use3.
- Test Method:
- Weigh a known mass of the sample into a crucible.
- Evaporate the sample to constant weight (e.g., using an oven at 103 ± 2°C).
- Calculate moisture/volatile matter content using the formula:
\2 where \(W_1\) = original sample mass, \(W_2\) = empty crucible mass, and \(W_3\) = crucible + dried material mass2, 3.
- Normative Reference: EAS 847-1 (Glossary of terms)3.
3. Acid Value and Free Fatty Acids (DEAS 847-4: 2025)
- Scope: Applies to oils and fats for cosmetic industry4.
- Test Method:
- Principle: Titrate the sample in an alcoholic medium (e.g., ethanol) with aqueous sodium or potassium hydroxide, using phenolphthalein as an indicator. For dark-colored oils, thymolphthalein or alkali blue 6B may be used4.
- Calculation:
- Acid Value: Expressed as mg of KOH required to neutralize 1 g of sample.
- Free Fatty Acids: Calculated as oleic acid (or other relevant fatty acid) and expressed as a percentage4.
- Reagents:
- Ethanol (neutral to phenolphthalein).
- Phenolphthalein indicator solution (1% w/v in ethanol)4.
- Normative Reference: EAS 847-1 (Glossary of terms)4.
4. Glossary of Terms (DEAS 847-1: 2025 / DEAS 846: 2025)
- Purpose: Provides standardized definitions for terms used in analytical methods (e.g., acid value, free fatty acids, insoluble impurities) to ensure consistency1, 5.
- Key Definitions:
Legal Framework and Compliance
- Authority:
- Harmonization:
- Updates and Review:
- Enforcement in Kenya:
- While the EAS are regional standards, Kenya enforces them through national legislation, including the Standards Act (Cap. 496) and the Kenya Bureau of Standards (KEBS). Non-compliance may result in product recalls, fines, or legal action.
Summary Answer
Kenya’s updated analytical standards for cosmetics and oils are governed by the East African Standards (EAS) 847 series, which prescribe standardized testing methods for insoluble impurities2, moisture content3, acid value4, and free fatty acids4. These standards are developed by the East African Standards Committee (EASC) and enforced in Kenya through the Kenya Bureau of Standards (KEBS). Compliance requires adherence to the specific test methods outlined in DEAS 847-2/3/4: 2025, including titration for acid value4, evaporation for moisture content3, and filtration for insoluble impurities2. The EAS 847-1 glossary ensures consistent interpretation of terms5. Businesses must use the latest versions of these standards to avoid trade barriers and legal penalties1.
