[quote:1jsnxrl7]1.มีสูตรแชมพูชนิดใส ใช้สารเคมีน้อย ๆ หรืออ่อนโยน แนะนำมั๊ยครับ[/quote:1jsnxrl7]

หากท่านสมาชิกหมายความ คำว่า สารเคมี หมายถึง สารที่ไม่ได้เกิดขึ้นเองได้ ตามธรรมดา ไม่มีสารทำความสะอาดชนิดใดในโลก ที่ไม่ใช่สารเคมีคะ ที่มีอ้างอิงว่าเป็นสารทำความสะอาดธรรมชาติ เช่น Soap Bark ก็มีประสิทธิภาพต่ำมาก ไม่สามารถในมาใช้ทำความสะอาดได้จริง

[quote:1jsnxrl7]2.เคยใช้ Essential Oil อย่างน้ำมันมะกรูดมาผสม แล้วขุ่น ต้องใช้อะไรทำให้ใสครับ
ใช้พวก Polysorbate อย่าง [url=http://www.myskinrecipes.com/shop/emulsifier/175-polysorbate-20-tween-20.html:1jsnxrl7]Tween 20[/url:1jsnxrl7] จะช่วยให้ใสไหมครับ เห็นว่าค่อนข้างปลอดภัย
หรือมีตัวอื่นแนะนำ-พร้อมข้อดีข้อเสียครับ[/quote:1jsnxrl7]

Clear, Low-Chemical Shampoo Formulation Advice

Here is some advice regarding your questions about formulating a clear, low-chemical shampoo, based on your experience and the information provided:

1. Clear, Gentle, Low-Chemical Shampoo Formula

It's important to understand that all cleaning agents are chemicals. The term "low-chemical" often refers to using milder surfactants or minimizing certain types of synthetic ingredients. While a specific formula isn't provided, you can create a gentler shampoo by selecting mild primary and secondary surfactants (like Cocamidopropyl Betaine, which you are already using) and incorporating conditioning agents and appropriate thickeners.

2. Making Essential Oils Clear in Shampoo

Essential oils are oils and do not naturally mix clearly with water-based shampoo formulas, causing cloudiness. To make them disperse clearly, you need a solubilizer.

Flora Solve Clear: This is specifically designed to solubilize fragrance oils and essential oils in water or water-based gels without using alcohol. It is noted for providing clear, colorless, and odorless solutions and has good temperature stability. You would typically mix Flora Solve Clear with the essential oil first (usually 2-5 parts Flora Solve Clear to 1 part essential oil) before adding this mixture to your shampoo base.
Polysorbate 20: This is also a common solubilizer used in cosmetic formulations. It can help disperse oils in water, but it might not achieve perfect clarity with all types or amounts of essential oils, and its performance can be affected by temperature compared to Flora Solve Clear. It is considered relatively safe.

Flora Solve Clear is generally recommended for better clarity and stability when incorporating essential oils into clear water-based products like shampoo.

3. Reducing the "Grippy" Feeling After Washing

The "grippy" or "squeaky clean" feeling is often a sign that the shampoo has effectively removed oils from the hair, potentially leaving the hair cuticle raised and less smooth. To counteract this and add slip and softness while minimizing harsh chemicals, you can add a conditioning agent to your shampoo formula.

Options include:

Silicone-based conditioners: These are very effective at providing softness, smoothness, and reducing tangling by coating the hair shaft. Options that can be mixed directly into water-based formulas include Silicone Quick-Cond (provides clarity and ease of use, moderate effectiveness), SiliWater (provides softness and weight without build-up, clear liquid), and Silicone Hi-Cond (provides maximum coating and softness, milky liquid). While silicones are synthetic, they are widely used for their conditioning benefits.
Non-silicone conditioners: If you prefer to avoid silicones, alternatives like GuarCat Standard or GuarCat Clear (natural guar gum derivatives) and Poly-Conditioner Pro can provide conditioning properties. GuarCat helps with softness and can also add viscosity. GuarCat Clear is a specific type that helps maintain formula clarity. Poly-Conditioner Pro also provides softness and smoothness and is suitable for silicone-free formulas.

Adding a small percentage (typically 0.1-3%) of a suitable conditioning agent can significantly improve the feel of the hair after washing.

4. Calculating Percentages in Formulations

In cosmetic formulations, percentages are almost always calculated by weight of the total formula. This means if a formula is 100 grams, and an ingredient is used at 1%, you would add 1 gram of that ingredient. The total weight of all ingredients (water, surfactants, thickeners, oils, etc.) adds up to 100%.

For example, in a 100g shampoo formula:

Water: 60g (60%)
Surfactant A: 20g (20%)
Surfactant B: 10g (10%)
Thickener: 2g (2%)
Conditioning Agent: 1g (1%)
Essential Oil: 0.5g (0.5%)
Solubilizer: 1.5g (1.5% - assuming a 3:1 ratio for the essential oil)
Preservative, Fragrance, etc.: 5g (5%)

Total: 100g (100%)

Always measure ingredients by weight for accuracy.

5. Alternatives to Cocamide DEA for Thickening and Essential Oil Stability

If you want to avoid Cocamide DEA for thickening, there are several alternatives that can also help achieve a clear shampoo:

ClearClean: This is an Acrylates Crosspolymer thickener that provides high clarity and viscosity, even allowing for the suspension of beads or pigments in the formula. It works well in a pH range of 4-6.
EasyThick: This is another thickener specifically for shampoos and liquid soaps. It is easy to use and provides a clear texture.
SugarThick: Derived from sugar, this thickener (PEG-120 Methyl Glucose Dioleate) is suitable for detergent-based formulas, provides a clear gel texture, and can also help reduce irritation from harsh surfactants.

These thickeners can help achieve the desired viscosity without using Cocamide DEA.

Regarding keeping essential oils stable and dispersed long-term, as mentioned in point 2, using an effective solubilizer like Flora Solve Clear is key. It creates a stable micro-emulsion that keeps the oil dispersed evenly throughout the shampoo, preventing separation and maintaining clarity over time.
