1. **Understanding Keratohyalin:**
- Keratohyalin is a protein that forms dense cytoplasmic granules in the skin.

2. **Identifying the Role of Keratohyalin:**
- It plays a crucial role in the keratinization process, which is the formation of a protective layer of keratin in the skin.

3. **Effects of Keratohyalin:**
- Keratohyalin causes dehydration of the cells and promotes cross-linking of keratin fibers, which enhances the strength and resilience of the skin.

4. **Locating Keratohyalin in the Skin Layers:**
- Keratohyalin is specifically found in the stratum granulosum, which is the granular third layer of the epidermis.

5. **Evaluating the Options:**
- The options given are:
- Corium
- Stratum corneum
- Stratum lucidum
- Stratum granulosum
- After evaluating, we find that:
- Corium is incorrect.
- Stratum corneum is incorrect.
- Stratum lucidum is incorrect.
- Stratum granulosum is correct.

6. **Conclusion:**
- Therefore, keratohyalin is a transparent substance present in the stratum granulosum.

**Final Answer:**
Keratohyalin is a transparent substance present in the stratum granulosum.
